    Stefano Pietrosanti

    2016-03-01

    Full Text Available In this paper, a power management strategy (PMS has been developed for the control of energy storage in a system subjected to loads of random duration. The PMS minimises the costs associated with the energy consumption of specific systems powered by a primary energy source and equipped with energy storage, under the assumption that the statistical distribution of load durations is known. By including the variability of the load in the cost function, it was possible to define the optimality criteria for the power flow of the storage. Numerical calculations have been performed obtaining the control strategies associated with the global minimum in energy costs, for a wide range of initial conditions of the system. The results of the calculations have been tested on a MATLAB/Simulink model of a rubber tyre gantry (RTG crane equipped with a flywheel energy storage system (FESS and subjected to a test cycle, which corresponds to the real operation of a crane in the Port of Felixstowe. The results of the model show increased energy savings and reduced peak power demand with respect to existing control strategies, indicating considerable potential savings for port operators in terms of energy and maintenance costs.

  7. Energy Management Strategies for Diesel Hybrid Electric Vehicle

    Grondin Olivier

    2015-01-01

    Full Text Available This paper focuses on hybrid energy management for a Diesel Hybrid Electric Vehicle (HEV with a parallel architecture. The proposed strategy focuses on the reduction of Nitric Oxides (NOx emissions that represents a key issue to meet diesel emissions standards. The strategy is split in two separated functions aiming at limiting the NOx in steady-state and transient operating conditions. The first functions, control the torque split between the engine and the electric motor. This energy management is based on the Equivalent Consumption Minimization Strategy (ECMS where an additional degree of freedom is introduced to tune the optimization tradeoffs from the pure fuel economy case to the pure NOx limitation case. The second function adapts the torque split ratio between the motor and the engine, initially computed from the optimal control strategy during transient operations where NOx are produced. The engine torque correction relies on mean value models for the EGR system dynamics and for the NOx formation. This paper applies a methodology based on Software in the Loop (SiL and Hardware in the Loop (HiL simulations in order to understand the system performance according to the powertrain configurations and also to tune the proposed energy management strategy. The simulation results are confirmed by experiments performed on Hybrid-Hardware in the Loop (Hy-HiL test bench. This work shows the potential of using the hybrid architecture to limit NOx emissions by choosing the best operating point and by limiting the engine dynamics. The NOx reduction has limited impact on fuel consumption.

  8. Public sector energy management: A strategy for catalyzing energy efficiency in Malaysia

    Science.gov (United States)

    Roy, Anish Kumar

    To date the public sector role in facilitating the transition to a sustainable energy future has been envisaged mainly from a regulatory perspective. In such a role, the public sector provides the push factors---enforcing regulations and providing incentives---to correct market imperfections that impede energy transitions. An alternative and complementary role of the public sector that is now gaining increasing attention is that of catalyzing energy transitions through public sector energy management initiatives. This dissertation offers a conceptual framework to rationalize such a role for the public sector by combining recent theories of sustainable energy transition and public management. In particular, the framework identifies innovative public management strategies (such as performance contracting and procurement) for effectively implementing sustainable energy projects in government facilities. The dissertation evaluates a model of sustainable public sector energy management for promoting energy efficiency in Malaysia. The public sector in Malaysia can be a major player in leading and catalyzing energy efficiency efforts as it is not only the largest and one of the most influential energy consumers, but it also plays a central role in setting national development strategy. The dissertation makes several recommendations on how a public sector energy management strategy can be implemented in Malaysia. The US Federal Energy Management Program (FEMP) is used as a practical model. The analysis, however, shows that in applying the FEMP model to the Malaysian context, there are a number of limitations that will have to be taken into consideration to enable a public sector energy management strategy to be effectively implemented. Overall the analysis of this dissertation contributes to a rethinking of the public sector role in sustainable energy development that can strengthen the sector's credibility both in terms of governance and institutional performance.

  10. Real Time Energy Management Control Strategies for Hybrid Powertrains

    Science.gov (United States)

    Zaher, Mohamed Hegazi Mohamed

    In order to improve fuel efficiency and reduce emissions of mobile vehicles, various hybrid power-train concepts have been developed over the years. This thesis focuses on embedded control of hybrid powertrain concepts for mobile vehicle applications. Optimal robust control approach is used to develop a real time energy management strategy for continuous operations. The main idea is to store the normally wasted mechanical regenerative energy in energy storage devices for later usage. The regenerative energy recovery opportunity exists in any condition where the speed of motion is in opposite direction to the applied force or torque. This is the case when the vehicle is braking, decelerating, or the motion is driven by gravitational force, or load driven. There are three main concepts for regernerative energy storing devices in hybrid vehicles: electric, hydraulic, and flywheel. The real time control challenge is to balance the system power demand from the engine and the hybrid storage device, without depleting the energy storage device or stalling the engine in any work cycle, while making optimal use of the energy saving opportunities in a given operational, often repetitive cycle. In the worst case scenario, only engine is used and hybrid system completely disabled. A rule based control is developed and tuned for different work cycles and linked to a gain scheduling algorithm. A gain scheduling algorithm identifies the cycle being performed by the machine and its position via GPS, and maps them to the gains.

    This paper proposes a novel topology of multimode hybrid energy storage system (HESS) and its energy management strategy for electric vehicles (EVs). Compared to the conventional HESS, the proposed multimode HESS has more operating modes and thus it could in further enhance the efficiency of the system. The rule-based control strategy and the power-balancing strategy are developed for the energy management strategy to realize mode selection and power distribution. Generally, the DC-DC converter will operate at peak efficiency to convey the energy from the batteries to the UCs. Otherwise, the pure battery mode or the pure ultracapacitors (UCs) mode will be utilized without the DC-DC converter. To extend the battery life, the UCs have the highest priority to recycle the energy and the batteries are isolated from being recharged directly during regenerative braking. Simulations and experiments are established to validate the proposed multimode HESS and its energy management strategy. The results reveal that the energy losses in the DC-DC converter, the total energy consumption and the overall system efficiency of the proposed multimode HESS are improved compared to the conventional HESS.

    Offering high efficiency and producing zero emissions Fuel Cells (FCs) represent an excellent alternative to internal combustion engines for powering vehicles to alleviate the growing pollution in urban environments. Due to inherent limitations of FCs which lead to slow transient response, FC-based vehicles incorporate an energy storage system to cover the fast power variations. This paper considers a FC/supercapacitor platform that configures a hard constrained powertrain providing an adverse scenario for the energy management strategy (EMS) in terms of fuel economy and drivability. Focusing on palliating this problem, this paper presents a novel EMS based on the estimation of short-term future energy demand and aiming at maintaining the state of energy of the supercapacitor between two limits, which are computed online. Such limits are designed to prevent active constraint situations of both FC and supercapacitor, avoiding the use of friction brakes and situations of non-power compliance in a short future horizon. Simulation and experimentation in a case study corresponding to a hybrid electric bus show improvements on hydrogen consumption and power compliance compared to the widely reported Equivalent Consumption Minimization Strategy. Also, the comparison with the optimal strategy via Dynamic Programming shows a room for improvement to the real-time strategies.

    Fuel cell vehicles, as a substitute for internal-combustion-engine vehicles, have become a research hotspot for most automobile manufacturers all over the world. Fuel cell systems have disadvantages, such as high cost, slow response and no regenerative energy recovery during braking; hybridization can be a solution to these drawbacks. This paper presents a fuel cell hybrid bus which is equipped with a fuel cell system and two energy storage devices, i.e., a battery and an ultracapacitor. An energy management strategy based on fuzzy logic, which is employed to control the power flow of the vehicular power train, is described. This strategy is capable of determining the desired output power of the fuel cell system, battery and ultracapacitor according to the propulsion power and recuperated braking power. Some tests to verify the strategy were developed, and the results of the tests show the effectiveness of the proposed energy management strategy and the good performance of the fuel cell hybrid bus.

    Progress is reported in formulating energy management strategies for stand-alone PV systems, developing an analytical tool that can be used to investigate these strategies, applying this tool to determine the proper control algorithms and control variables (controller inputs and outputs) for a range of applications, and quantifying the relative performance and economics when compared to systems that do not apply energy management. The analysis technique developed may be broadly applied to a variety of systems to determine the most appropriate energy management strategies, control variables and algorithms. The only inputs required are statistical distributions for stochastic energy inputs and outputs of the system and the system's device characteristics (efficiency and ratings). Although the formulation was originally driven by stand-alone PV system needs, the techniques are also applicable to hybrid and grid connected systems.

    Full Text Available This paper demonstrates an energy management method using traffic information for commuter hybrid electric vehicles. A control strategy based on stochastic dynamic programming (SDP is developed, which minimizes on average the equivalent fuel consumption, while satisfying the battery charge-sustaining constraints and the overall vehicle power demand for drivability. First, according to the sample information of the traffic speed profiles, the regular route is divided into several segments and the statistic characteristics in the different segments are constructed from gathered data on the averaged vehicle speeds. And then, the energy management problem is formulated as a stochastic nonlinear and constrained optimal control problem and a modified policy iteration algorithm is utilized to generate a time-invariant state-dependent power split strategy. Finally, simulation results over some driving cycles are presented to demonstrate the effectiveness of the proposed energy management strategy.

In order to ensure the supply-demand balance under the conditions of higher variability the micro-grid concept of active distribution networks arising as a promising one. However, to achieve all the potential benefits that micro-gird concept offer, it is important to determine optimal operating strategies for micro-grids. The present paper compares three energy management strategies, aimed at ensuring economical micro-grid operation, to find a compromise between the complexity of strategy and its efficiency. The first strategy combines optimization technique and an additional rule while the second strategy is based on the pure optimization approach. The third strategy uses model based predictive control scheme to take into account uncertainties in renewable generation and energy consumption. In order to compare the strategies with respect to cost effectiveness, a residential micro-grid comprising photovoltaic modules, thermal energy storage system, thermal loads, electrical loads as well as combined heat and power plant, is considered.

  11. Energy management action plan: Developing a strategy for overcoming institutional barriers to municipal energy conservation

    Energy Technology Data Exchange (ETDEWEB)

    1992-12-31

    Energy offices working to improve efficiency of local government facilities face not only technical tasks, but institutional barriers, such as budget structures that do not reward efficiency, a low awareness of energy issues, and purchasing procedures based only on minimizing initial cost. The bureau, in working to remove such barriers in San Francisco, has identified 37 institutional barriers in areas such as operations & maintenance, purchasing, and facility design; these barriers were then reorganized into three groupings-- policy & attitudes, budget & incentives, and awareness & information-- and mapped. This map shows that the barriers mutually reinforce each other, and that a holistic approach is required for permanent change. The city`s recreation & parks department was used as a model department, and information about facility energy use was compiled into a departmental energy review. Staff interviews showed how barriers affect conservation. The bureau then generated ideas for projects to remove specific barriers and rated them according to potential impact and the resources required to implement them. Four of the six projects selected focused on maintenance staff: a cost- sharing lighting retrofit program, a boiler efficiency program, a departmental energy tracking system, and a budgetary incentive program for conservation. The other two projects are city-wide: promotion of a new term contract supplying energy-efficient light materials, and publication/distribution of ENERGY NEWS newsletter. A general methodology, the EMAP Strategy Guide, has been created to assist other energy offices in developing EMAPs.

    2016-11-01

    Full Text Available The rule-based logic threshold control strategy has been frequently used in energy management strategies for hybrid electric vehicles (HEVs owing to its convenience in adjusting parameters, real-time performance, stability, and robustness. However, the logic threshold control parameters cannot usually ensure the best vehicle performance at different driving cycles and conditions. For this reason, the optimization of key parameters is important to improve the fuel economy, dynamic performance, and drivability. In principle, this is a multiparameter nonlinear optimization problem. The logic threshold energy management strategy for an all-wheel-drive HEV is comprehensively analyzed and developed in this study. Seven key parameters to be optimized are extracted. The optimization model of key parameters is proposed from the perspective of fuel economy. The global optimization method, DIRECT algorithm, which has good real-time performance, low computational burden, rapid convergence, is selected to optimize the extracted key parameters globally. The results show that with the optimized parameters, the engine operates more at the high efficiency range resulting into a fuel savings of 7% compared with non-optimized parameters. The proposed method can provide guidance for calibrating the parameters of the vehicle energy management strategy from the perspective of fuel economy.

    Full Text Available This paper attempted to control a hybrid DC microgrid in islanded operation mode using decentralized power management strategies. Proposed adaptive I/V characteristic for hybrid photovoltaic (PV and battery energy storage system (BESS and wind turbine generator (WTG adapts the distributed energy resources (DER behavior independently in accordance with the load demand. Hence, the PV module can spend its maximum power on load demand and spend the extra power for charging the BESS, which will regulate DC bus voltage and maintain the power balance within the microgrid. When load demand is beyond the maximum generation power of PV unit, WTG will supply the energy shortage. The proposed control system was applied on the DC microgrid in order to achieve control objectives through a decentralized procedure, without telecommunication links. In order to validate the proposed strategies, the control system was implemented on a DC microgrid within MATLAB/SIMULINK, where the simulation results were analyzed and validated.

Different energy management strategies were investigated based on analysis of the two systems. And the two buses were compared with each other in a bus cycle and constant speed testing. The Polymer Electrolyte Membrane Fuel Cell (PEMFC) in FCB A showed an advantage in fuel economy for it worked usually in the high efficient range of the PEMFC engine. The hydrogen consumption rate in the cycle testing was 7.9 kg/100 km and 9.8 kg/100 km for FCB A and FCB B, and in the 40 kmph constant speed testing it was 3.3 kg/100 km and 4.0 kg/100 km, respectively. The fuel economy could be improved when the hydrogen and air supply subsystems are optimized and controlled with an advanced algorithm. It could also benefit from a braking energy regeneration system. Compared with FCB A, the PEMFC in FCB B worked under unfavorable operation conditions because its working range was comparatively wide, and the power changing rate was relatively large from a statistical point of view, which resulted in performance recession of the PEMFC in FCB B. After a mileage of 7000 km, the output power of the PEMFC in FCB B was reduced by 10%, compared with 2.4% in FCB A. An advanced energy management strategy is necessary to split the power between the PEMFC and a battery suitable for long durability of a PEMFC.

    Energy management strategy plays a key role for Fuel Cell Hybrid Electric Vehicles (FCHEVs), it directly affects the efficiency and performance of energy storages in FCHEVs. For example, by using a suitable energy distribution controller, the fuel cell system can be maintained in a high efficiency region and thus saving hydrogen consumption. In this paper, an energy management strategy for online driving cycles is proposed based on a combination of the parameters from three offline optimized fuzzy logic controllers using data fusion approach. The fuzzy logic controllers are respectively optimized for three typical driving scenarios: highway, suburban and city in offline. To classify patterns of online driving cycles, a Probabilistic Support Vector Machine (PSVM) is used to provide probabilistic classification results. Based on the classification results of the online driving cycle, the parameters of each offline optimized fuzzy logic controllers are then fused using Dempster-Shafer (DS) evidence theory, in order to calculate the final parameters for the online fuzzy logic controller. Three experimental validations using Hardware-In-the-Loop (HIL) platform with different-sized FCHEVs have been performed. Experimental comparison results show that, the proposed PSVM-DS based online controller can achieve a relatively stable operation and a higher efficiency of fuel cell system in real driving cycles.

  20. Power and Energy Management Strategy for Solid State Transformer Interfaced DC Microgrid

    As a result of more and more applications of renewable energy into our ordinary life, how to construct a microgrid (MG) based on the distributed renewable energy resources and energy storages, and then to supply a reliable and flexible power to the conventional power system are the hottest topics nowadays. Comparing to the AC microgrid (AC MG), DC microgrid (DC MG) gets more attentions, because it has its own advantages, such as high efficiency, easy to integrate the DC energy sources and energy storages, and so on. Furthermore, the interaction between DC MG system and the distribution system is also an important and practical issue. In Future Renewable Electric Energy Delivery and Management Systems Center (FREEDM), the Solid State Transformer (SST) is built, which can transform the distribution system to the low AC and DC system directly (usually home application level). Thus, the SST gives a new promising solution for low voltage level MG to interface the distribution level system instead of the traditional transformer. So a SST interfaced DC MG is proposed. However, it also brings new challenges in the design and control fields for this system because the system gets more complicated, which includes distributed energy sources and storages, load, and SST. The purpose of this dissertation is to design a reliable and flexible SST interfaced DC MG based on the renewable energy sources and energy storages, which can operate in islanding mode and SST-enabled mode. Dual Half Bridge (DHB) is selected as the topology for DC/DC converter in DC MG. The DHB operation procedure and average model are analyzed, which is the basis for the system modeling, control and operation. Furthermore, two novel power and energy management strategies are proposed. The first one is a distributed energy management strategy for the DC MG operating in the SST-enabled mode. In this method, the system is not only in distributed control to increase the system reliability, but the power sharing

    We examine the relationships among employees’ use of energy management strategies and two occupational well-being outcomes: job satisfaction and emotional exhaustion. Based on conservation of resources theory, it was hypothesized that employees with high job demands would benefit more from using energy management strategies (i.e., including prosocial, organizing, and meaning-related strategies), compared to employees with low job demands. We tested this proposition using a quantitative diary study. Fifty-four employees provided data twice daily across one work week (on average, 7 daily entries). Supporting the hypotheses, prosocial energy management was positively related to job satisfaction. Moreover, employees with high job demands were less emotionally exhausted when using prosocial strategies. Contrary to predictions, when using organizing strategies, employees with low job demands had higher job satisfaction and lower emotional exhaustion. Under high job demands, greater use of organizing strategies was associated with lower job satisfaction and higher emotional exhaustion. Finally, use of meaning-related strategies was associated with higher emotional exhaustion when job demands were low. With this research, we position energy management as part of a resource investment process aimed at maintaining and improving occupational well-being. Our findings show that this resource investment will be more or less effective depending on the type of strategy used and the existing drain on resources (i.e., job demands). This is the first study to examine momentary effects of distinct types of work-related energy management strategies on occupational well-being. PMID:28912741

    2014-02-01

    Full Text Available For a gasoline-hybrid electric vehicle (HEV, the energy management strategy (EMS is the computation of the distribution between electric and gasoline propulsion. Until recently, the EMS objective was to minimize fuel consumption. However, decreasing fuel consumption does not directly minimize the pollutant emissions, and the 3-way catalytic converter (3WCC must be taken into account. This paper proposes to consider the pollutant emissions in the EMS, by minimizing, with the Pontryagin minimum principle, a tradeoff between pollution and fuel consumption. The integration of the 3WCC temperature in the EMS is discussed and finally a simplification is proposed.

    2018-02-01

    Full Text Available This paper analyzes the impact of photovoltaic (PV systems on storage and electric vehicles in micro-grids. As these kinds of systems are becoming increasingly popular in the residential sector, the development of a new generation of equipment, such as more efficient batteries or solar panels, makes further study necessary. These systems are especially interesting in commercial or office buildings, since they have a more repetitive daily pattern of electricity consumption, which usually occurs within the maximum solar radiation hours. Based on this need, a novel control strategy aimed at efficiently managing this kind of micro-grid is proposed. The core of this strategy is a rule-based controller managing the power flows between the grid and the batteries of both the PV system and the electric vehicle. Through experimental data and simulations, this strategy was tested under different scenarios. The selected testbed consisted of the laboratory of a research center, which could be easily scalable to the entire building. Results showed the benefits of using an electric vehicle as an active agent in energy balance, leading to a reduction of the energetic costs of a micro-grid.

    Full Text Available The multi-energy management strategy of electric drive system of tracked bulldozer was researched. Firstly, based on power requirement of typical working condition of a tracked bulldozer, the power distribution strategy for three energy sources in the front power chain was proposed by using wavelet theory and fuzzy control theory. Secondly, the electric drive system simulation platform was built in MATLAB/Simulink. At last, a driver-controller based HILS (hardware-in-the-loop simulation platform was built and the multi-energy management strategy was verified. The HILS result shows that front power chain’s power output can meet the back power chain’s requirement, the engine-generator set works near the best fuel consumption curve, and the battery pack’s charge-discharge frequency and current are low. Thus the designed multi-energy management strategy can be used in real-time control of electric drive bulldozer.

    The addition of a fast auxiliary power source like a supercapacitor bank in fuel cell-based vehicles has a great potential because permits a significant reduction of the hydrogen consumption and an improvement of the vehicle efficiency. The Energy Management Strategies, commanding the power split between the power sources in the hybrid arrangement to fulfil the power requirement, perform a fundamental role to achieve this objective. In this work, three strategies based on the knowledge of the fuel cell efficiency map are proposed. These strategies are attractive due to the relative simplicity of the real time implementation and the good performance. The strategies are tested both in a simulation environment and in an experimental setup using a 1.2-kW PEM fuel cell. The results, in terms of hydrogen consumption, are compared with an optimal case, which is assessed trough an advantageous technique also introduced in this work and with a pure fuel cell vehicle as well.

    Full Text Available Energy storage systems (ESS play an important role in the performance of mining vehicles. A hybrid ESS combining both batteries (BTs and supercapacitors (SCs is one of the most promising solutions. As a case study, this paper discusses the optimal hybrid ESS sizing and energy management strategy (EMS of 14-ton underground load-haul-dump vehicles (LHDs. Three novel contributions are added to the relevant literature. First, a multi-objective optimization is formulated regarding energy consumption and the total cost of a hybrid ESS, which are the key factors of LHDs, and a battery capacity degradation model is used. During the process, dynamic programming (DP-based EMS is employed to obtain the optimal energy consumption and hybrid ESS power profiles. Second, a 10-year life cycle cost model of a hybrid ESS for LHDs is established to calculate the total cost, including capital cost, operating cost, and replacement cost. According to the optimization results, three solutions chosen from the Pareto front are compared comprehensively, and the optimal one is selected. Finally, the optimal and battery-only options are compared quantitatively using the same objectives, and the hybrid ESS is found to be a more economical and efficient option.

    Full Text Available An energy management strategy (EMS is important for hybrid electric vehicles (HEVs since it plays a decisive role on the performance of the vehicle. However, the variation of future driving conditions deeply influences the effectiveness of the EMS. Most existing EMS methods simply follow predefined rules that are not adaptive to different driving conditions online. Therefore, it is useful that the EMS can learn from the environment or driving cycle. In this paper, a deep reinforcement learning (DRL-based EMS is designed such that it can learn to select actions directly from the states without any prediction or predefined rules. Furthermore, a DRL-based online learning architecture is presented. It is significant for applying the DRL algorithm in HEV energy management under different driving conditions. Simulation experiments have been conducted using MATLAB and Advanced Vehicle Simulator (ADVISOR co-simulation. Experimental results validate the effectiveness of the DRL-based EMS compared with the rule-based EMS in terms of fuel economy. The online learning architecture is also proved to be effective. The proposed method ensures the optimality, as well as real-time applicability, in HEVs.

    2015-04-01

    Full Text Available Plug-in hybrid electric vehicles (PHEVs have been recognized as one of the most promising vehicle categories nowadays due to their low fuel consumption and reduced emissions. Energy management is critical for improving the performance of PHEVs. This paper proposes an energy management approach based on a particle swarm optimization (PSO algorithm. The optimization objective is to minimize total energy cost (summation of oil and electricity from vehicle utilization. A main drawback of optimal strategies is that they can hardly be used in real-time control. In order to solve this problem, a rule-based strategy containing three operation modes is proposed first, and then the PSO algorithm is implemented on four threshold values in the presented rule-based strategy. The proposed strategy has been verified by the US06 driving cycle under the MATLAB/Simulink software environment. Two different driving cycles are adopted to evaluate the generalization ability of the proposed strategy. Simulation results indicate that the proposed PSO-based energy management method can achieve better energy efficiency compared with traditional blended strategies. Online control performance of the proposed approach has been demonstrated through a driver-in-the-loop real-time experiment.

    Full Text Available This paper presents the results of the implementation of a self-consumption maximization strategy tested in a real-scale Vanadium Redox Flow Battery (VRFB (5 kW, 60 kWh and Building Integrated Photovoltaics (BIPV demonstrator (6.74 kWp. The tested energy management strategy aims to maximize the consumption of energy generated by a BIPV system through the usage of a battery. Whenever possible, the residual load is either stored in the battery to be used later or is supplied by the energy stored previously. The strategy was tested over seven days in a real-scale VRF battery to assess the validity of this battery to implement BIPV-focused energy management strategies. The results show that it was possible to obtain a self-consumption ratio of 100.0%, and that 75.6% of the energy consumed was provided by PV power. The VRFB was able to perform the strategy, although it was noticed that the available power (either to charge or discharge varied with the state of charge.

    2015-04-01

    A hybrid powertrain configuration based on a proton exchange membrane (PEMFC), a battery and a supercapacitor (SC) is designed without grid connection for the LF-LRV tramway. In order to avoid rapid changes of power demand and achieve high efficiency without degrading the mechanism performance, a power sharing strategy based on a combination of fuzzy logic control (FLC) and Haar wavelet transform (Haar-WT) is proposed for an energy management system of the hybrid tramway. The results demonstrate that the proposed energy management system is able to ensure the major positive portion of the low frequency components of power demand can be deals with the PEMFC. The battery can help provide a portion of the positive low frequency components of power demand to reduce the PEMFC burden while the SC bank can supply all the high frequency components which could damage the PEMFC membrane. Therefore, the energy management system of high-power hybrid tramway is able to guarantee a safe operating condition with transient free for the PEMFC and extend the lifetime of each power source. Finally, the comparisons with other control strategies verify that the proposed energy management system can achieve better energy efficiency of the overall hybrid tramway.

    2016-04-01

    In early lactation, most of the dairy cows are in negative energy balance; the extent and duration depend in part on the feeding strategy. Previous studies showed an increased lactation milk yield by use of a live weight (LW) adjusted feeding strategy with a high energy diet before and a reduced energy diet after LW nadir compared with a standard diet throughout lactation. The objective of the present study was to examine how such an individualized feeding strategy affects plasma indicators of energy status. It was hypothesized that an energy-enriched diet until LW nadir will reduce the severity of the negative energy balance, and that the reduction in diet energy concentration from LW nadir will extend the negative energy balance period further. Sixty-two Holstein cows (30% first parity) were managed for 16 months extended lactation and randomly allocated to one of two feeding strategies at calving. Two partially mixed rations were used, one with a high energy density (HD) and a 50 : 50 forage : concentrate ratio, and one with a lower energy density (LD, control diet) and a 60 : 40 forage : concentrate ratio. Half of the cows were offered the HD diet until they reached at least 42 days in milk and a LW gain⩾0 kg/day based on a 5-days LW average, and were then shifted to the LD diet (strategy HD-LD). The other half of the cows were offered the LD diet throughout lactation (control strategy LD-LD). Weekly blood samples were drawn for analysis of plasma metabolites and hormones. Before the shift in diet, the HD-LD cows had higher glucose and lower beta-hydroxybutyrate and non-esterified fatty acids (NEFA) concentrations than the LD-LD cows. After the shift until 36 weeks after calving, plasma NEFA was higher in HD-LD than LD-LD cows. Insulin and insulin-like growth factor-1 were not affected by the feeding strategy. To conclude, in early lactation, the energy-enriched diet reduced the negative energy balance. Plasma NEFA was higher in HD-LD than LD-LD cows from

This paper proposes a fuzzy-logic power management strategy based on Markov random prediction for an active parallel battery-UC HESS. The proposed power management strategy; the inputs for which are the vehicle speed; the current electric power demand and the predicted electric power demand; is used to distribute the electrical power between the battery bank and the UC bank. In this way; the battery bank power is limited to a certain range; and the peak and average charge/discharge power of the battery bank and overall loss incurred by the whole HESS are also reduced. Simulations and scaled-down experimental platforms are constructed to verify the proposed power management strategy. The simulations and experimental results demonstrate the advantages; feasibility and effectiveness of the fuzzy-logic power management strategy based on Markov random prediction.

    Full Text Available Recently, second-life battery systems have received a growing interest as one of the most promising alternatives for decreasing the overall cost of the battery storage systems in stationary applications. The high-cost of batteries represents a prominent barrier for their use in traction and stationary applications. To make second-life batteries economically viable for stationary applications, an effective power-electronics converter should be selected as well. This converter should be supported by an energy management strategy (EMS, which is needed for controlling the power flow among the second-life battery modules based on their available capacity and performance. This article presents the design, analysis and implementation of a generic energy management strategy (GEMS. The proposed GEMS aims to control and distribute the load demand between battery storage systems under different load conditions and disturbances. This manuscript provides the experimental verification of the proposed management strategy. The results have demonstrated that the GEMS can robustly handle any level of performance inequality among the used-battery modules with the aim to integrate different levels (i.e., size, capacity, and chemistry type of the second-life battery modules at the same time and in the same application.

    The building sector is primarily responsible for a major part of total energy consumption. The European Energy Performance of Buildings Directives (EPBD) emphasized the need to reduce the energy consumption in buildings, and put forward the rationale for developing Near to Zero Energy Buildings (NZEB). Passive and active strategies help architects to minimize the use of active HVAC systems, taking advantage of the available natural resources such as solar radiation, thermal variability and daylight. The building envelope plays a decisive role in passive and active design strategies. The ideal transparent façade would be one with optical properties, such as Solar Heat Gain Coefficient (SHGC) and Visible Transmittance (VT), that could readily adapt in response to changing climatic conditions or occupant preferences. The aim of this article consists of describing the system to maintain a small glazed pavilion located in Sofia (Bulgaria) at the desired interior temperature over a whole year. The system comprises i) the use of Water Flow Glazing facades (WFG) and Radiant Interior Walls (RIW), ii) the use of free cooling devices along with traditional heat pump connected to photo-voltaic panels and iii) the use of a new Energy Management System that collects data and acts accordingly by controlling all components. The effect of these strategies and the use of active systems, like Water Flow Glazing, are analysed by means of simulating the prototype over one year. Summer and Winter energy management strategies are discussed in order to change the SHGC value of the Water Flow Glazing and thus, reduce the required energy to maintain comfort conditions.

    2014-09-01

    Full Text Available The paper proposes a generic methodology to incorporate constraints (pollutant emission, battery health, drivability into on-line energy management strategies (EMSs for hybrid electric vehicles (HEVs and plug-in hybrid electric vehicles (PHEVs. The integration of each constraint into the EMS, made with the Pontryagin maximum principle, shows a tradeoff between the fuel consumption and the constraint introduced. As state dynamics come into play (catalyst temperature, battery cell temperature, etc., the optimization problem becomes more complex. Simulation results are presented to highlight the contribution of this generic strategy, including constraints compared to the standard approach. These results show that it is possible to find an energy management strategy that takes into account an increasing number of constraints (drivability, pollution, aging, environment, etc.. However, taking these constraints into account increases fuel consumption (the existence of a trade-off curve. This trade-off can be sometimes difficult to find, and the tools developed in this paper should help to find an acceptable solution quickly

    Water-Energy-Land (WEL) Nexus management is one of those complex decision problems where holistic approach to supply-demand management considering different criteria would be valuable. However, multi-criteria decision making with diverse indicators measured on different scales and uncertainty levels is difficult to solve. On the other hand, climate adaptation and mitigation need to be integrated, and resource sensitive regions like Mediterranean provide ample opportunities towards that end. While the water sector plays a key role in climate adaptation, mitigation focuses on the energy and agriculture sector. Recent studies on the so-called WEL nexus confirm the potential synergies to be derived from mainstreaming climate adaptation in the water sector, while simultaneously addressing opportunities for co-management with energy (and also land use). Objective of this paper is to develop scenarios for the future imbalances in water & energy supply and demand for a water stressed Mediterranean area of Northern Spain (Catalonia) and to test the scenario based climate adaptation & mitigation strategy for WEL management policies. Resource sensitive area of Catalonia presents an interesting nexus problem to study highly stressed water demand scenario (representing all major demand sectors), very heterogeneous land use including intensive agriculture to diversified urban and industrial uses, and mixed energy supply including hydro, wind, gas turbine to nuclear energy. Different energy sectors have different water and land requirements. Inter-river basin water transfer is another factor which is considered for this area. The water-energy link is multifaceted. Energy production can affect water quality, while energy is used in water treatment and to reduce pollution. Similarly, hydropower - producing energy from water - and desalination - producing freshwater using energy - both play important role in economic growth by supplying large and secure amounts of 'green' energy or

  14. Development & optimization of a rule-based energy management strategy for fuel economy improvement in hybrid electric vehicles

    Science.gov (United States)

    Asfoor, Mostafa

    The gradual decline of oil reserves and the increasing demand for energy over the past decades has resulted in automotive manufacturers seeking alternative solutions to reduce the dependency on fossil-based fuels for transportation. A viable technology that enables significant improvements in the overall energy conversion efficiencies is the hybridization of conventional vehicle drive systems. This dissertation builds on prior hybrid powertrain development at the University of Idaho. Advanced vehicle models of a passenger car with a conventional powertrain and three different hybrid powertrain layouts were created using GT-Suite. These different powertrain models were validated against a variety of standard driving cycles. The overall fuel economy, energy consumption, and losses were monitored, and a comprehensive energy analysis was performed to compare energy sources and sinks. The GT-Suite model was then used to predict the formula hybrid SAE vehicle performance. Inputs to this model were a numerically predicted engine performance map, an electric motor torque curve, vehicle geometry, and road load parameters derived from a roll-down test. In this case study, the vehicle had a supervisory controller that followed a rule-based energy management strategy to insure a proper power split during hybrid mode operation. The supervisory controller parameters were optimized using discrete grid optimization method that minimized the total amount of fuel consumed during a specific urban driving cycle with an average speed of approximately 30 [mph]. More than a 15% increase in fuel economy was achieved by adding supervisory control and managing power split. The vehicle configuration without the supervisory controller displayed a fuel economy of 25 [mpg]. With the supervisory controller this rose to 29 [mpg]. Wider applications of this research include hybrid vehicle controller designs that can extend the range and survivability of military combat platforms. Furthermore, the

    Objectives are to: (1) Investigate novel engine control strategies targeted at rapid engine/catalyst warming for the purpose of mitigating tailpipe emissions from plug-in hybrid electric vehicles (PHEV) exposed to multiple engine cold start events; and (2) Validate and optimize hybrid supervisory control techniques developed during previous and on-going research projects by integrating them into the vehicle level control system and complementing them with the modified engine control strategies in order to further reduce emissions during both cold start and engine re-starts. Approach used are: (1) Perform a literature search of engine control strategies used in conventional powertrains to reduce cold start emissions; (2) Develop an open source engine controller providing full access to engine control strategies in order to implement new engine/catalyst warm-up behaviors; (3) Modify engine cold start control algorithms and characterize impact on cold start behavior; and (4) Develop an experimental Engine-In-the-Loop test stand in order to validate control methodologies and verify transient thermal behavior and emissions of the real engine when combined with a virtual hybrid powertrain. Some major accomplishments are: (1) Commissioned a prototype engine controller on a GM Ecotec 2.4l direct injected gasoline engine on an engine test cell at the University of Tennessee. (2) Obtained from Bosch (with GM's approval) an open calibration engine controller for a GM Ecotec LNF 2.0l Gasoline Turbocharged Direct Injection engine. Bosch will support the bypass of cold start strategies if calibration access proves insufficient. The LNF engine and its open controller were commissioned on an engine test cell at ORNL. (3) Completed a literature search to identify key engine cold start control parameters and characterized their impact on the real engine using the Bosch engine controller to calibrate them.

    2014-01-01

    Development of dependable systems relies on the ability of the system to determine and respond to off-nominal system behavior. Specification and development of these fault management capabilities must be done in a structured and principled manner to improve our understanding of these systems, and to make significant gains in dependability (safety, reliability and availability). Prior work has described a fundamental taxonomy and theory of System Health Management (SHM), and of its operational subset, Fault Management (FM). This conceptual foundation provides a basis to develop framework to design and implement FM design strategies that protect mission objectives and account for system design limitations. Selection of an SHM strategy has implications for the functions required to perform the strategy, and it places constraints on the set of possible design solutions. The framework developed in this paper provides a rigorous and principled approach to classifying SHM strategies, as well as methods for determination and implementation of SHM strategies. An illustrative example is used to describe the application of the framework and the resulting benefits to system and FM design and dependability.

    Although there are recommendations for the management of osteoarthritis (OA), little is known about how people with OA actually manage this chronic condition. The aims of this study were to identify the non-pharmacological and pharmacological therapies most commonly used for the management of hip or knee OA, in a community-based sample of adults, and to compare these with evidence-based recommendations. A questionnaire was mailed to 2,200 adult members of Arthritis Queensland living in Brisbane, Australia. It included questions about OA symptoms, management therapies, and demographic characteristics. Of the 485 participants (192 men, 293 women) with hip or knee OA who completed the questionnaire, most had mild to moderate symptoms. Ninety-six percent of participants (aged 27-95 years) reported using at least one non-pharmacological therapy, and 78% reported using at least one pharmacological therapy. The most common currently used non-pharmacological strategy was range-of-motion exercises (men 52%, women 61%, p = 0.05) and the most common frequently used pharmacological strategy was glucosamine/chondroitin (men 51%, women 60%, ns). For the most highly recommended strategies, 65% of men and 54% of women had never attended an information/education course (p = 0.04), and fewer than half (46% of women and 42% of men, p = 0.03) were frequent users of anti-inflammatory agents. The findings suggest that many people with knee or hip OA do not follow the most highly endorsed of the Osteoarthritis Research Society International recommendations for management of OA. Health professionals should be encouraged to recommend evidence-based therapies to their patients.

    Full Text Available This study considers load control in a multi-residential setup where energy scheduler (ES devices installed in smart meters are employed for demand-side management (DSM. Several residential end-users share the same energy source and each residential user has non-adjustable loads and adjustable loads. In addition, residential users may have storage devices and renewable energy sources such as wind turbines or solar as well as dispatchable generators. The ES devices exchange information automatically by executing an iterative distributed algorithm to locate the optimal energy schedule for each end-user. This will reduce the total energy cost and the peak-to-average ratio (PAR in energy demand in the electric power distribution. Users possessing storage devices and dispatchable generators strategically utilise their resources to minimise the total energy cost together with the PAR. Simulation results are provided to evaluate the performance of the proposed game theoretic-based distributed DSM technique.

    Full Text Available This paper presents a rule-based energy management strategy for a plug-in hybrid school bus (PHSB. In order to verify the effectiveness and rationality of the proposed energy management strategy, the powertrain and control models were built with MATLAB/Simulink. The PHSB powertrain model includes an engine model, ISG (integrated started and generator model, drive motor model, power battery packs model, driver model, and vehicle longitudinal dynamics model. To evaluate the controller area network (CAN bus performance features such as the bus load, signal hysteresis, and to verify the reliability and real-time performance of the CAN bus multi-node control method, a co-simulation platform was built with CANoe and MATLAB/Simulink. The co-simulation results show that the control strategy can meet the requirements of the PHSB’s dynamic performance. Meanwhile, the charge-depleting mode (CD and charge-sustaining mode (CS can switch between each other and maintain a state-of-charge (SoC of around 30%, indicating that the energy management strategy effectively extends the working period of the CD mode and improves the fuel economy further. The energy consumption per 100 km includes 13.7 L diesel and 10.5 kW·h electricity with an initial SoC of 75%. The CANoe simulation results show that the bus communication performs well without error frames.

    Full Text Available Energy management strategy influences the power performance and fuel economy of plug-in hybrid electric vehicles greatly. To explore the fuel-saving potential of a plug-in hybrid electric bus (PHEB, this paper searched the global optimal energy management strategy using dynamic programming (DP algorithm. Firstly, the simplified backward model of the PHEB was built which is necessary for DP algorithm. Then the torque and speed of engine and the torque of motor were selected as the control variables, and the battery state of charge (SOC was selected as the state variables. The DP solution procedure was listed, and the way was presented to find all possible control variables at every state of each stage in detail. Finally, the appropriate SOC increment is determined after quantizing the state variables, and then the optimal control of long driving distance of a specific driving cycle is replaced with the optimal control of one driving cycle, which reduces the computational time significantly and keeps the precision at the same time. The simulation results show that the fuel economy of the PEHB with the optimal energy management strategy is improved by 53.7% compared with that of the conventional bus, which can be a benchmark for the assessment of other control strategies.

    Syuan-Yi Chen

    2016-01-01

    Full Text Available This study developed an integrated energy management/gear-shifting strategy by using a bacterial foraging algorithm (BFA in an engine/motor hybrid powertrain with electric continuously variable transmission. A control-oriented vehicle model was constructed on the Matlab/Simulink platform for further integration with developed control strategies. A baseline control strategy with four modes was developed for comparison with the proposed BFA. The BFA was used with five bacterial populations to search for the optimal gear ratio and power-split ratio for minimizing the cost: the equivalent fuel consumption. Three main procedures were followed: chemotaxis, reproduction, and elimination-dispersal. After the vehicle model was integrated with the vehicle control unit with the BFA, two driving patterns, the New European Driving Cycle and the Federal Test Procedure, were used to evaluate the energy consumption improvement and equivalent fuel consumption compared with the baseline. The results show that [18.35%,21.77%] and [8.76%,13.81%] were improved for the optimal energy management and integrated optimization at the first and second driving cycles, respectively. Real-time platform designs and vehicle integration for a dynamometer test will be investigated in the future.

First, rising energy unit costs continue to erode NASA's mission budget. NASA spent roughly $156M on facility energy in FY 2007. Although that represents less than one per cent of NASA's overall annual budget, the upward trend in energy costs concerns the agency. While NASA reduced consumption 13%, energy unit costs have risen 63%. Energy cost increases counteract the effects of energy conservation, which results in NASA buying less yet spending more. The second factor is federal energy legislation. The National Energy Conservation Policy Act, as amended by the Energy Policy Act of 2005, Executive Order (EO) 13423 (January, 2007), and the Energy Independence and Security Act (December, 2007), mandates energy/water conservation goals for all federal agencies, including NASA. There are also reporting requirements associated with this legislation. The Energy/Water Management Task was created to support NASA Headquarters Environmental Management Division (HO EMD) in meeting these requirements. With assistance from TEERM, HQ EMD compiled and submitted the NASA Annual Report to the Department of Energy FY 2007. The report contains information on how NASA is meeting federally mandated energy and water management goals. TEERM monitored input for timeliness, errors, and conformity to the new energy/water reporting guidelines and helped compile the information into the final report. TEERM also assists NASA Energy/Water Management with proposal and award calls, updates to the energy/water management database, and facilitating communication within the energy/water management community. TEERM is also supporting NASA and the Interagency Working Group (IWG) on Hydrogen and Fuel Cells. Established shortly after the President announced the Hydrogen Fuel Initiative in 2003, this IWG serves as the mechanism for collaboration among the Federal agencies

    Despite an abundant endowment of energy resources, Angola's people and its economy suffer from lack of reliable energy supplies. In 2003, the country emerged from almost three decades of civil war that left much of its infrastructure destroyed or damaged and a large part of its population displaced. Increasing access to modern energy sources in a sustainable manner would help improve livelihoods directly, as well as indirectly through the promotion of economic development. At the request of the Angolan government in 2005, the IEA conducted a survey of the Angolan energy sector and energy policies. The request spurred several visits to Angola by IEA teams who met with energy sector officials and other stakeholders collecting documentation in the capital, Luanda and in Lubango. The results of these efforts are an independent review of the major energy policy issues facing the country. While Angola faces many energy challenges, there are lessons in this analysis that are applicable in many other developing countries. This inclusive review on Angola focuses on areas for priority action and hones in on energy sub-sectors likely to play the largest role in meeting domestic demand for modern energy services: notably electricity and oil products. As biomass currently plays an immense role in meeting the bulk of the energy needs of Angolan households, this sub-sector is also featured, with emphasis on improving the sustainability of this renewable energy source. A realistic update on Angola's present day energy situation is offered and the main priorities which could form the basis of an effective overall energy strategy are presented.

  19. Romania needs a strategy for thermal energy

    Full Text Available The energy sector in Romania consists of three sub-sectors: electricity, natural gas and heat. Among these, the sub-sector of thermal energy is in the most precarious situation because it has been neglected for a long time. This sub-sector is particularly important both due to the amount of final heat consumption (of over 50% of final energy consumption, and to the fact that it has a direct negative effect on the population, industry and services. This paper presents the main directions for developing a modern strategy of the thermal energy sub-sector, which would fit into Romania’s Energy Strategy that is still in preparation This is based on the author’s 50 years of experience in this field that includes knowledge about the processes and the equipment of thermal energy, expertise in the management and restructuring of energy companies and also knowledge of the specific legislation. It is therefore recommended, following the European regulations and practices, the promotion and upgrading of district heating systems using efficient cogeneration, using trigeneration in Romania, modernizing buildings in terms of energy use, using of renewable energy sources for heating, especially biomass, and modernizing the energy consumption of rural settlements.

    Peak and average energy usage in domestic and industrial environments is growing rapidly and absence of detailed energy consumption metrics is making systematic reduction of energy usage very difficult. Smart energy management system aims at providing a cost-effective solution for managing soaring energy consumption and its impact on green house gas emissions and climate change. The solution is based on seamless integration of existing wired and wireless communication technologies combined with smart context-aware software which offers a complete solution for automation of energy measurement and device control. The persuasive software presents users with easy-to-assimilate visual cues identifying problem areas and time periods and encourages a behavioural change to conserve energy. The system allows analysis of real-time/statistical consumption data with the ability to drill down into detailed analysis of power consumption, CO2 emissions and cost. The system generates intelligent projections and suggests potential methods (e.g. reducing standby, tuning heating/cooling temperature, etc.) of reducing energy consumption. The user interface is accessible using web enabled devices such as PDAs, PCs, etc. or using SMS, email, and instant messaging. Successful real-world trial of the system has demonstrated the potential to save 20 to 30% energy consumption on an average. Low cost of deployment and the ability to easily manage consumption from various web enabled devices offers gives this system a high penetration and impact capability offering a sustainable solution to act on climate change today.

    2014-12-01

    The Northeastern United States (NE) relies heavily on thermoelectric power plants (90% of total capacity) to provide electricity to more than 70 million people. This region's power plants require consistent, large volumes of water at sufficiently cold temperatures to generate electricity efficiently, and withdraw approximately 10.5 trillion gallons of water annually. Previous findings indicate that assessments of future electricity pathways must account for water availability, water temperature and the changing climate, as changes in these conditions may limit operational efficiency in the future. To account for such electric system vulnerabilities, we have created a link between an electricity system capacity expansion model (ReEDS) and a hydrologic model that is coupled to a power plant simulation model (FrAMES-TP2M) that allows for a new approach to analyze electricity system development, performance, and environmental impacts. Together, these coupled tools allow us to estimate electricity development and operations in the context of a changing climate and impacts on the seasonal spatial and temporal variability of water resources, downstream thermal effluents that cause plant-to-plant interferences and harm aquatic habitat, economic costs of water conservation methods and associated carbon emissions. In this study, we test and compare a business-as-usual strategy with three alternative water management scenarios that include changes in cooling technologies and water sources utilized for the years 2014-2050. Results of these experiments can provide useful insight into the feasibility of the electricity expansion scenarios in terms of associated water use and thermal impacts, carbon emissions, the cost of generating electricity, and also highlight the importance of accounting for water resources in future power sector planning and performance assessments.

    2005-10-01

    There is a disconnect in most companies between strategy formulation and strategy execution. On average, 95% of a company's employees are unaware of, or do not understand, its strategy. If employees are unaware of the strategy, they surely cannot help the organization implement it effectively. It doesn't have to be like this. For the past 15 years, the authors have studied companies that achieved performance breakthroughs by adopting the Balanced Scorecard and its associated tools to help them better communicate strategy to their employees and to guide and monitor the execution of that strategy. Some companies, of course, have achieved better, longer-lasting improvements than others. The organizations that have managed to sustain their strategic focus have typically established a new corporate-level unit to oversee all activities related to strategy: an office of strategy management (OS M). The OSM, in effect, acts as the CEO's chief of staff. It coordinates an array of tasks: communicating corporate strategy; ensuring that enterprise-level plans are translated into the plans of the various units and departments; executing strategic initiatives to deliver on the grand design; aligning employees' plans for competency development with strategic objectives; and testing and adapting the strategy to stay abreast of the competition. The OSM does not do all the work, but it facilitates the processes so that strategy is executed in an integrated fashion across the enterprise. Although the companies that Kaplan and Norton studied use the Balanced Scorecard as the framework for their strategy management systems, the authors say the lessons of the OSM are applicable even to companies that do not use it.

    The electricity market was de-regulated in Finland at the end of 1995 and the customers can now freely choose their power suppliers. The national grid and local distribution network operators are now separated from the energy business. The network operators transmit the electric power to the customers on equal terms regardless from whom the power is purchased. The Finnish national grid is owned by one company Finnish Power Grid PLC (Fingrid). The major shareholders of Fingrid are the state of Finland, two major power companies and institutional investors. In addition there are about 100 local distribution utilities operating the local 110 kV, 20 kV and 0.4 kV networks. The distribution utilities are mostly owned by the municipalities and towns. In each network one energy supplier is always responsible for the hourly energy balance in the network (a `host`) and it also has the obligation to provide public energy prices accessible to any customer in the network`s area. The Finnish regulating authorities nominate such a supplier who has a dominant market share in the network`s area as the supplier responsible for the network`s energy balance. A regulating authority, called the Electricity Market Centre, ensures that the market is operating properly. The transmission prices and public energy prices are under the Electricity Market Centre`s control. For domestic and other small customers the cost of hourly metering (ca. 1000 US$) would be prohibitive and therefore the use of conventional energy metering and load models is under consideration by the authorities. Small customer trade with the load models (instead of the hourly energy recording) is scheduled to start in the first half of 1998. In this presentation, the problems of energy management from the standpoint of the energy trading and distributing companies in the new situation are first discussed. The topics covered are: the hourly load data management, the forecasting and estimation of hourly energy demands

  7. Blazing the energy trail: The Municipal Energy Management Program

    Energy Technology Data Exchange (ETDEWEB)

    1994-12-01

    The Urban Consortium Energy Task Force pioneers energy and environmental solutions for US cities and counties. When local officials participate in the task force, they open the door to many resources for their communities. The US is entering a period of renewed interest in energy management. Improvements in municipal energy management allow communities to free up energy operating funds to meet other needs. These improvements can even keep energy dollars in the community through the purchase of services and products used to save energy. With this idea in mind, the US Department of Energy Municipal Energy Management Program has funded more than 250 projects that demonstrate innovative energy technologies and management tools in cities and counties through the Urban Consortium Energy Task Force (UCETF). UCETF helps the US Department of Energy foster municipal energy management through networks with cities and urbanized counties and through links with three national associations of local governments. UCETF provides funding for projects that demonstrate innovative and realistic technologies, strategies, and methods that help urban America become more energy efficient and environmentally responsible. The task force provides technical support to local jurisdictions selected for projects. UCETF also shares information about successful energy management projects with cities and counties throughout the country via technical reports and project papers. The descriptions included here capsulize a sample of UCETF`s demonstration projects around the country.

  8. Impact of Different Driving Cycles and Operating Conditions on CO2 Emissions and Energy Management Strategies of a Euro-6 Hybrid Electric Vehicle

    Directory of Open Access Journals (Sweden)

    Claudio Cubito

    2017-10-01

    Full Text Available Although Hybrid Electric Vehicles (HEVs represent one of the key technologies to reduce CO2 emissions, their effective potential in real world driving conditions strongly depends on the performance of their Energy Management System (EMS and on its capability to maximize the efficiency of the powertrain in real life as well as during Type Approval (TA tests. Attempting to close the gap between TA and real world CO2 emissions, the European Commission has decided to introduce from September 2017 the Worldwide Harmonized Light duty Test Procedure (WLTP, replacing the previous procedure based on the New European Driving Cycle (NEDC. The aim of this work is the analysis of the impact of different driving cycles and operating conditions on CO2 emissions and on energy management strategies of a Euro-6 HEV through the limited number of information available from the chassis dyno tests. The vehicle was tested considering different initial battery State of Charge (SOC, ranging from 40% to 65%, and engine coolant temperatures, from −7 °C to 70 °C. The change of test conditions from NEDC to WLTP was shown to lead to a significant reduction of the electric drive and to about a 30% increase of CO2 emissions. However, since the specific energy demand of WLTP is about 50% higher than that of NEDC, these results demonstrate that the EMS strategies of the tested vehicle can achieve, in test conditions closer to real life, even higher efficiency levels than those that are currently evaluated on the NEDC, and prove the effectiveness of HEV technology to reduce CO2 emissions.

  9. Energy strategy: Roadmap to consensus

    1990-11-01

    The United States lacks a comprehensive approach to policy-making in the energy realm. Today, as in the past, individual constituency groups tend to focus on their particular aspect of the energy challenge. Many employ a decide-announce-defend'' approach to policy-making, setting out to secure a unilateral advantage for themselves. By so doing, they inevitably pit interest against interest. The result is a polarization of constituencies, and shortsighted policies designed to address the issue of the moment. The American Energy Assurance Council (AEAC) is a non-profit organization founded in 1987 for the sole purpose of facilitating progress toward a fair efficient wise, stable, and consensus-based national energy strategy. AEAC does not have a substantive policy agencies. Rather, we are committed to supporting a process whereby the many stakeholders and policy makers concerned with energy-related issues can come together in productive discourse, thereby overcoming ignorance of each other's positions. The Council seeks to act as a facilitative body, providing a safe'' context for inventive and creative thinking. We attempt to build a store of common knowledge, and to build on that store according to mutually agreed-upon groundrules, and employing sophisticated approaches to facilitation and mediation. This report, the National Energy Consensus Experiment (NECE), was an ambitious experiment in consensus-building. We learned a great deal from it, both in terms of substance and process, and we are convinced that it holds important lessons for others who may seek to build consensus in the public policy realm.

    2014-10-01

    Full Text Available The objectives of energy management are resource conservation, climate protection and cost savings, while the users have permanent access to the energy they need. Much of the importance of energy saving stems from the global need to save energy - this global need affects energy prices, emissions targets, and legislation. Many companies are trying to promote its image and time protect the climate through a proactive and public energy strategy. In a divisional organization, there should be a central and several sector-specific energy management units. So the diverse needs of the individual sectors and the coordination between the branches and the head office can be fulfilled. There are basically 4 steps to the energy management process and we will explore them in turn, before looking at the impact of energy management on information technology and the ethics behind such an approach.

    Change, chaos, and uncertainty touch every part of every institution. The laboratory is not immune. Managers content to continue on their familiar path soon will find themselves bypassed. To meet today's challenges, directors of technical operations, laboratory directors, team leaders, and coordinators need plenty of creativity--from everyone on their staff. It is no longer just "nice" to improve group output and problem-solving skills while staying within a "shoestring" budget. It is absolutely necessary. In this article, we explore strategies laboratory managers can use to tap the creative potential and commitment of their people. These strategies work. Whether it involves using humor, creating "idea centers," or "deconstructing the bureaucracy," the goal is the same: to encourage clinical managers to think beyond their technical and managerial experience. The examples in this article may not suit the needs, situations, or tastes of all laboratory managers. They are "food for thought." The concepts and strategies these examples illustrate are every laboratory manager's keys to adapting successfully to future challenges.

    2012-01-01

    Water and wastewater systems are significant energy consumers with an estimated 3%-4% of total U.S. electricity consumption used for the movement and treatment of water and wastewater. Water-energy issues are of growing importance in the context of water shortages, higher energy and material costs, and a changing climate. In this economic environment, it is in the best interest for utilities to find efficiencies, both in water and energy use. Performing energy audits at water and wastewater treatment facilities is one way community energy managers can identify opportunities to save money, energy, and water. In this paper the importance of energy use in wastewater facilities is illustrated by a case study of a process energy audit performed for Crested Butte, Colorado's wastewater treatment plant. The energy audit identified opportunities for significant energy savings by looking at power intensive unit processes such as influent pumping, aeration, ultraviolet disinfection, and solids handling. This case study presents best practices that can be readily adopted by facility managers in their pursuit of energy and financial savings in water and wastewater treatment. This paper is intended to improve community energy managers understanding of the role that the water and wastewater sector plays in a community's total energy consumption. The energy efficiency strategies described provide information on energy savings opportunities, which can be used as a basis for discussing energy management goals with water and wastewater treatment facility managers.

    2001-10-01

    The economic survival of any nation depends upon its ability to produce and manage sufficient supplies of low-cost safe energy. The world's consumption of fossil fuel resources currently increasing at 3% per annum is found to be unsustainable. Projections of this trend show that mankind will exhaust all known reserves in the second half of the coming century. Governments, industrialists, commercial organizations, public sector departments and the general public have now become aware of the urgent requirements for the efficient management of resources and energy-consuming activities. Most organizations in the materials, manufacturing and retail sectors and in the service industries have also created energy management departments, or have employed consultants, to monitor energy consumption and to reduce wastage. Conversely, any sustained attempt to reduce rates of energy consumption even by as little as 0.1% per annum ensures relatively an eternal future supply as well as reduction on environmental and ecological effect. Thus, there is no long- term solution to energy flow problem other than systematic and effective energy management and the continuous application of the techniques of energy management. Essential energy management strategies in support of a sustainable energy- economy are discussed.

    2017-08-01

    Full Text Available A novel and flexible interconnecting framework for microgrids and corresponding energy management strategies are presented, in response to the situation of increasing renewable-energy penetration and the need to alleviate dependency on energy storage equipment. The key idea is to establish complementary energy exchange between adjacent microgrids through a multiport electrical energy router, according to the consideration that adjacent microgrids may differ substantially in terms of their patterns of energy production and consumption, which can be utilized to compensate for each other’s instant energy deficit. Based on multiport bidirectional voltage source converters (VSCs and a shared direct current (DC power line, the energy router serves as an energy hub, and enables flexible energy flow among the adjacent microgrids and the main grid. The analytical model is established for the whole system, including the energy router, the interconnected microgrids and the main grid. Various operational modes of the interconnected microgrids, facilitated by the energy router, are analyzed, and the corresponding control strategies are developed. Simulations are carried out on the Matlab/Simulink platform, and the results have demonstrated the validity and reliability of the idea for microgrid interconnection as well as the corresponding control strategies for flexible energy flow.

    The IEA Policy Pathway publications provide details on how to implement specific recommendations drawn from the IEA 25 Energy Efficiency Policy Recommendations. This Policy Pathway, jointly produced by the International Energy Agency and the Institute for Industrial Productivity, develops the critical steps for policy makers implementing energy management programmes for industry. Optimising energy use in industry is essential to improve industrial competitiveness and achieve wider societal goals such as energy security, economic recovery and development, climate change mitigation and environmental protection. While there is significant potential to decrease energy consumption in this sector, opportunities to improve energy efficiency are still under-exploited. Energy management programmes have shown to be instrumental in addressing many of the barriers that inhibit wide-scale uptake of energy management in industry. The Policy Pathway builds on lessons learned from country experiences and provides actionable guidance on how to plan and design, implement, evaluate and monitor energy management programmes for industry.

Obesity requires appropriate and effective management by suitably trained members of a multidisciplinary team, with treatment programmes putting equal importance on weight reduction and its maintenance. Such programmes must also take into account the reduction in risk from co-morbid conditions after modest weight loss (5-10% of initial body weight). The use of an anti-obesity drug may be justified for patients at risk from obesity where dietary methods, including exercise and behaviour modification, have failed to achieve a 10% reduction in initial body weight after at least three months from the start of the episode of managed care. Anti-obesity drugs must be prescribed in an appropriate setting, with patients being reviewed on a regular basis. Essential elements for managed weight loss include, a printed management programme, appropriate equipment, specified and realistic weight-loss goals, documentation of individual patient's health risks, and clearly defined follow-up procedures with explicit guidelines for the use of drugs and notification of other doctors involved in the patient's care. The process of drug treatment necessitates a system of regular medical audit. Many health-care professionals and lay persons remain sceptical about the scientific value of anti-obesity drugs. The emergence of increasingly specific and effective agents underlines the importance of ensuring appropriate use for patients at risk from obesity.

  13. Dispatch Strategy Development for Grid-tied Household Energy Systems

    Cardwell, Joseph

    The prevalence of renewable generation will increase in the next several decades and offset conventional generation more and more. Yet this increase is not coming without challenges. Solar, wind, and even some water resources are intermittent and unpredictable, and thereby create scheduling challenges due to their inherent "uncontrolled" nature. To effectively manage these distributed renewable assets, new control algorithms must be developed for applications including energy management, bridge power, and system stability. This can be completed through a centralized control center though efforts are being made to parallel the control architecture with the organization of the renewable assets themselves--namely, distributed controls. Building energy management systems are being employed to control localized energy generation, storage, and use to reduce disruption on the net utility load. One such example is VOLTTRONTM, an agent-based platform for building energy control in real time. In this thesis, algorithms developed in VOLTTRON simulate a home energy management system that consists of a solar PV array, a lithium-ion battery bank, and the grid. Dispatch strategies are implemented to reduce energy charges from overall consumption (/kWh) and demand charges (/kW). Dispatch strategies for implementing storage devices are tuned on a month-to-month basis to provide a meaningful economic advantage under simulated scenarios to explore algorithm sensitivity to changing external factors. VOLTTRON agents provide automated real-time optimization of dispatch strategies to efficiently manage energy supply and demand, lower consumer costs associated with energy usage, and reduce load on the utility grid.

    In the course of developing the National Energy Strategy, the Department of Energy held 15 public hearings, heard from more than 375 witnesses and received more than 1000 written comments. In April 1990, the Department published an Interim Report on the National Energy Strategy, which compiles those public comments. The National Energy Strategy must be based on actual experience and factual analysis of our energy, economic and environmental situation. This report by the Nuclear Power Oversight committee, which represents electric utilities and other organizations involved in supplying electricity from nuclear energy to the American people, provides such an analysis. The conclusions here are based on hard facts and actual worldwide experience. This analysis of all the available data supports -- indeed, dictates -- expanded reliance on nuclear energy in this nation's energy supply to achieve the President's goals. 33 figs.

  5. A Novel Strategy for Optimising Decentralised Energy Exchange for Prosumers

    Directory of Open Access Journals (Sweden)

    2016-07-01

    Full Text Available The realization of the Smart Grid vision will change the way of producing and distributing electrical energy. It paves the road for end-users to become pro-active in the distribution system and, equipped with renewable energy generators such as a photovoltaic panel, to become a so called “prosumer”. The prosumer is engaged in both energy production and consumption. Prosumers’ energy can be transmitted and exchanged as a commodity between end-users, disrupting the traditional utility model. The appeal of such scenario lies in the engagement of the end user, in facilitating the introduction and optimization of renewables, and in engaging the end-user in its energy management. To facilitate the transition to a prosumers’ governed grid, we propose a novel strategy for optimizing decentralized energy exchange in digitalized power grids, i.e., the Smart Grid. The strategy considers prosumer’s involvement, energy loss of delivery, network topology, and physical constraints of distribution networks. To evaluate the solution, we build a simulation program and design three meaningful evaluation cases according to different energy flow patterns. The simulation results indicate that, compared to traditional power distribution system, the maximum reduction of energy loss, energy costs, energy provided by the electric utility based using the proposed strategy can reach 51 % , 66 % , 97.5 % , depending on the strategy. Moreover, the proportion of energy self-satisfaction approaches reaches 98 % .

There are many facets to this energy consumption, including the characteristics of the house, its appliances, and the behaviours of its inhabitants. Because of this complexity, addressing only one of these facets is not effective in substantially reducing the overall energy consumption of households. This called for an interdisciplinary approach, merging the domains of design for sustainability, sustainable housing transformation and environmental psychology.

    In todays environment-conscious world, increasing levels of automotive emissions have been recognized as a major source of pollutants and greenhouse gases. Despite increasingly stringent tailpipe emission standards, the increased use of the automobile has more than offset the lowered per-vehicle emissions. Consequently, there is a great deal of interest in so-called zero-emission vehicles, such as electric and hybrid-electric automobiles. Although very attractive in terms of emissions, these vehicle present some design challenges which are not generally part of conventional automotive design. One such challenge is the development of an effective energy management strategy for the vehicle. While a conventional automobile has an engine whose power output far exceeds the average vehicle needs, hybrid electric vehicles generally have very limited energy reserves and efficiency in the use of these reserves is paramount if acceptable overall performance is to be achieved. Man aspects of the vehicle design (such as aerodynamics, powertrain design, gross weight, etc.) strongly influence the overall vehicle efficiency. However, the actual performance achieved by any given driver is strongly dependent on his or her driving skills. One way to reduce the effect of differences in driving skills is to provide for automatic accelerator control, permitting the vehicle to be driven in an efficient manner without necessitating extensive driver training. This report describes an accelerator/brake control systems developed for use on the Zia Roadrunner New Mexico Tech`s entry in the 1993 Sunrayce for solar-electric hybrid vehicles.

    The Government's Smart Grid Strategy brings Danish consumers a big step closer to managing their own energy consumption. The strategy, combines electricity meters read on an hourly basis with variable tariffs and a data hub. It will make it possible for consumers to use the power when it is least expensive. ''Today we set the course for developing a smart energy network that will reduce the cost of converting to sustainable energy, cut electricity bills and create brand new products consumers will welcome,'' says Minister of Climate, Energy and Building Martin Lidegaard. Encouraging consumers to use energy more efficiently is a key aspect of the strategy. The remote-read electricity meters are crucial if consumers are to play a role in optimising the flexible energy network. (LN)

  16. Energy management and cooperation in microgrids

    Science.gov (United States)

    Rahbar, Katayoun

    Microgrids are key components of future smart power grids, which integrate distributed renewable energy generators to efficiently serve the load demand locally. However, random and intermittent characteristics of renewable energy generations may hinder the reliable operation of microgrids. This thesis is thus devoted to investigating new strategies for microgrids to optimally manage their energy consumption, energy storage system (ESS) and cooperation in real time to achieve the reliable and cost-effective operation. This thesis starts with a single microgrid system. The optimal energy scheduling and ESS management policy is derived to minimize the energy cost of the microgrid resulting from drawing conventional energy from the main grid under both the off-line and online setups, where the renewable energy generation/load demand are assumed to be non-causally known and causally known at the microgrid, respectively. The proposed online algorithm is designed based on the optimal off-line solution and works under arbitrary (even unknown) realizations of future renewable energy generation/load demand. Therefore, it is more practically applicable as compared to solutions based on conventional techniques such as dynamic programming and stochastic programming that require the prior knowledge of renewable energy generation and load demand realizations/distributions. Next, for a group of microgrids that cooperate in energy management, we study efficient methods for sharing energy among them for both fully and partially cooperative scenarios, where microgrids are of common interests and self-interested, respectively. For the fully cooperative energy management, the off-line optimization problem is first formulated and optimally solved, where a distributed algorithm is proposed to minimize the total (sum) energy cost of microgrids. Inspired by the results obtained from the off-line optimization, efficient online algorithms are proposed for the real-time energy management

    2008-02-15

    This paper presented a vision with respect to a continental energy strategy and the principles and goals that must underlie such a strategy. These principles include relying on signals emanating from energy markets to guide investment; limiting the role of government to that of ensuring that the policy and institutional framework is conducive to the development and operation of competitive and innovative energy markets; and ensuring free and open energy trade in energy commodities, both within the continent and with the rest of the world. The paper also identified a number of important factors that, would shape and condition continental energy development and trade. The paper provided an overview of the North American energy use and supply situation for the following resources: oil; natural gas; electricity; coal; nuclear power; hydroelectricity; geothermal energy; wind power; solar power; and ethanol. It also discussed the contribution of the North American Free Trade Agreement (NAFTA) through increased natural gas exports. It was concluded that given the petroleum resources of the three countries and their increased value because of higher oil and gas prices, there was considerable incentive for Canada, the United States, and Mexico to streamline regulations in order to facilitate the efficient development, transportation, and use of the continent's energy resources in accordance with market conditions. 38 refs., 2 tabs., 21 figs.

    Full Text Available Plug-in hybrid electric vehicles (PHEVs can be considered as a hybrid system (HS which includes the continuous state variable, discrete event, and operation constraint. Thus, a model predictive control (MPC strategy for PHEVs based on the mixed logical dynamical (MLD model and short-term vehicle speed prediction is proposed in this paper. Firstly, the mathematical model of the controlled PHEV is set-up to evaluate the energy consumption using the linearized models of core power components. Then, based on the recognition of driving intention and the past vehicle speed data, a nonlinear auto-regressive (NAR neural network structure is designed to predict the vehicle speed for known driving profiles of city buses and the predicted vehicle speed is used to calculate the total required torque. Next, a MLD model is established with appropriate constraints for six possible driving modes. By solving the objective function with the Mixed Integer Linear Programming (MILP algorithm, the optimal motor torque and the corresponding driving mode sequence within the speed prediction horizon can be obtained. Finally, the proposed energy control strategy shows substantial improvement in fuel economy in the simulation results.

    Clinical and Biomedical Engineering managers are in a position to utilize their management skills and apply analytical strategies to identify and capture cost savings opportunities in their institutions. To do so, however, they may be required to expand their scope and extend beyond what may have been their traditional areas of responsibility. This paper examines how management skills, techniques, and strategies were applied to establish a program to manage the repair of rigid and flexible surgical scopes. The program resulted in substantial cost savings, as well as other significant quantitative and qualitative benefits, and further demonstrated the value of proper technology management in healthcare institutions.

  8. Energy Optimal Control Strategy of PHEV Based on PMP Algorithm

    2017-01-01

    Full Text Available Under the global voice of “energy saving” and the current boom in the development of energy storage technology at home and abroad, energy optimal control of the whole hybrid electric vehicle power system, as one of the core technologies of electric vehicles, is bound to become a hot target of “clean energy” vehicle development and research. This paper considers the constraints to the performance of energy storage system in Parallel Hybrid Electric Vehicle (PHEV, from which lithium-ion battery frequently charges/discharges, PHEV largely consumes energy of fuel, and their are difficulty in energy recovery and other issues in a single cycle; the research uses lithium-ion battery combined with super-capacitor (SC, which is hybrid energy storage system (Li-SC HESS, working together with internal combustion engine (ICE to drive PHEV. Combined with PSO-PI controller and Li-SC HESS internal power limited management approach, the research proposes the PHEV energy optimal control strategy. It is based on revised Pontryagin’s minimum principle (PMP algorithm, which establishes the PHEV vehicle simulation model through ADVISOR software and verifies the effectiveness and feasibility. Finally, the results show that the energy optimization control strategy can improve the instantaneity of tracking PHEV minimum fuel consumption track, implement energy saving, and prolong the life of lithium-ion batteries and thereby can improve hybrid energy storage system performance.

  10. Optimal Energy Management for Microgrids

    Science.gov (United States)

    Zhao, Zheng

    Microgrid is a recent novel concept in part of the development of smart grid. A microgrid is a low voltage and small scale network containing both distributed energy resources (DERs) and load demands. Clean energy is encouraged to be used in a microgrid for economic and sustainable reasons. A microgrid can have two operational modes, the stand-alone mode and grid-connected mode. In this research, a day-ahead optimal energy management for a microgrid under both operational modes is studied. The objective of the optimization model is to minimize fuel cost, improve energy utilization efficiency and reduce gas emissions by scheduling generations of DERs in each hour on the next day. Considering the dynamic performance of battery as Energy Storage System (ESS), the model is featured as a multi-objectives and multi-parametric programming constrained by dynamic programming, which is proposed to be solved by using the Advanced Dynamic Programming (ADP) method. Then, factors influencing the battery life are studied and included in the model in order to obtain an optimal usage pattern of battery and reduce the correlated cost. Moreover, since wind and solar generation is a stochastic process affected by weather changes, the proposed optimization model is performed hourly to track the weather changes. Simulation results are compared with the day-ahead energy management model. At last, conclusions are presented and future research in microgrid energy management is discussed.

    Comprehensive lifestyle interventions, including nutrition, physical activity, and behavioral therapy, are the foundation for clinical obesity management. New tools and treatment approaches help clinicians provide these interventions and support weight management in the primary care setting. Escalating treatment, such as using pharmacotherapy, medical devices, or bariatric surgery, are important considerations for appropriate patients who do not respond to lifestyle counseling. This article provides a review of obesity treatment in primary care and managed care settings. Principles of lifestyle changes for weight management, behavioral counseling, and options for pharmacotherapy, medical devices, and bariatric surgery are discussed.

    2009-08-15

    This research compares both attitudes and recycling behaviors in a sample of college males and females (N?=?302), a demographic group whose behaviors and willingness to adopt environmentally sound policies will become the dominant force for environmental reform in the USA in approaching decades. Consistent with prior research, women were significantly more likely to support strategies for energy conservation and were much more apt to always recycle. Among males (but not females), frequent recyclers of plastic were more supportive of energy conservation strategies, while for women, the link between attitudes and behavior is weaker, perhaps due to women's purported community-welfare orientation. In addition, because the strategies that received the most support from both sexes, walking to work or school, and purchasing and cooking with local produce, may reflect the resulting health benefits as much as concern for environmental sustainability, we should consider marketing the link between environmental altruism and personal wellbeing among young populations.

    2012-05-01

    The Green Data Center Project was a successful effort to significantly reduce the energy use of the National Snow and Ice Data Center (NSIDC). Through a full retrofit of a traditional air conditioning system, the cooling energy required to meet the data center’s constant load has been reduced by over 70% for summer months and over 90% for cooler winter months. This significant reduction is achievable through the use of airside economization and a new indirect evaporative cooling cycle. One of the goals of this project was to create awareness of simple and effective energy reduction strategies for data centers. Although this particular project was able to maximize the positive effects of airside economization and indirect evaporative cooling because of its geographic location, similar strategies may also be relevant for many other sites and data centers in the United States.

    2015-08-01

    In this article, we provide a review of the literature on self-management interventions and we are giving some thought to how, when, and by whom they should be offered to patients. The present literature based on randomized clinical trials has demonstrated benefits (reduced hospital admissions and improved health status) for chronic obstructive pulmonary disease (COPD) patients undergoing self-management interventions, although there are still problems with the heterogeneity among interventions, study populations, follow-up time, and outcome measures that make generalization difficult in real life. Key to the success, self-management intervention has to target behavior change. Proper self-management support is a basic prerequisite, for example, techniques and skills used by health care providers "case manager" to instrument patients with the knowledge, confidence, and skills required to effectively self-manage their disease. To improve health behaviors and engagement in self-management, self-management interventions need to target enhancing intrinsic motivation to change. This will best be done using client-centered communication (motivational communication) that encourages patients to express what intrinsically motivates them (e.g., consistent with their values or life goals) to adopt certain health behavior, with the goal of helping them overcome their ambivalence about change. Finally, if we want to be able to design and implement self-management interventions that are integrated, coherent, and have a strong likelihood of success, we need to take a more careful look and give more attention at the case manager, the patient (patient evaluation), and the quality assurance.

    Tzeel, E Albert

    2013-06-01

    Both the prevalence of type 2 diabetes mellitus (DM) and its associated costs have been rising over time and are projected to continue to escalate. Therefore, type 2 DM (T2DM) management costs represent a potentially untenable strain on the healthcare system unless substantial, systemic changes are made. Managed care organizations (MCOs) are uniquely positioned to attempt to make the changes necessary to reduce the burdens associated with T2DM by developing policies that align with evidence-based DM management guidelines and other resources. For example, MCOs can encourage members to implement healthy lifestyle choices, which have been shown to reduce DM-associated mortality and delay comorbidities. In addition, MCOs are exploring the strengths and weaknesses of several different benefit plan designs. Value-based insurance designs, sometimes referred to as value-based benefit designs, use both direct and indirect data to invest in incentives that change behaviors through health information technologies, communications, and services to improve health, productivity, quality, and financial trends. Provider incentive programs, sometimes referred to as "pay for performance," represent a payment/delivery paradigm that places emphasis on rewarding value instead of volume to align financial incentives and quality of care. Accountable care organizations emphasize an alignment between reimbursement and implementation of best practices through the use of disease management and/ or clinical pathways and health information technologies. Consumer-directed health plans, or high-deductible health plans, combine lower premiums with high annual deductibles to encourage members to seek better value for health expenditures. Studies conducted to date on these different designs have produced mixed results.

    1993-01-01

    The threat of global warming, environmental instability and the possible use of green or carbon taxes on fossil fuels has increased the need for energy efficiency. Energy Conservation is now recognised as one of the easiest and most cost-effective ways of limiting or reducing CO[sub 2] emissions. Large UK companies are now assessing how much CO[sub 2] they dissipate to the environment and reviewing strategies to reduce this either in response to consumer demand or as a corporate policy decision. Computer-based information systems already exist to monitor and report on fluctuations in energy consumption. These are called Monitoring and Targeting (M and T) systems. This paper explains what M and T systems are and how they are being extended to cover reporting on corporate fuel-based CO[sub 2] emissions to help provide an integrated energy and environmental-management information system.

    2015-11-01

    Full Text Available The ongoing debate on water policies in Spain is characterised by a traditional paradigm, dominated by the intervention on hydrological systems through the construction and management of infrastructure, which is progressively being abandoned but is currently still strong while the emergence of new management approaches. Climate change and the Water Framework Directive (WFD are, in addition, the background to increasing challenges to traditional perspectives on drought, and important steps have been taken towards their replacement. This work analyzes the evolution of the normative structure and management models to identify recent shifts. The analysis is based on a fundamental conceptual change that places drought in the framework of risk, rather than that of crisis. I argue for the need to advance new prevention policies that can finally overcome productivist inertia and undertake essential tasks such as reallocating water flows, revising and controlling the water-concession system, and reinforcing and guaranteeing public participation.

  5. Promoting sustainable energy strategies in Russia

    1995-12-31

    Enormous structural changes are taking place in the economy of Russia. It is important that vital sectors of the economy undergo a smooth transition from a centrally-planned paradigm to a more market-oriented structure. Introducing market-oriented-institutional structures and energy planning approaches to Russian utilities can facilitate the transition to the market and allow them to become vehicles for change rather than mere witnesses. As real electricity prices increase relative to other prices, a significant industrial restructuring can be expected, with an accompanying reduction of energy consumption. By developing programs to help industry become more energy-efficiency, the electricity sector can play a central role in Russia`s economic recovery. A robust energy sector will be in a much better position to lead other sectors of the economy toward market-oriented solutions to the present economic crisis. Because of the magnitude of the task of recreating an economy for one of the world`s superpowers, institutional restructuring should take place incrementally. The transition of US utilities from a {open_quotes}build-and-grow{close_quotes} paradigm to one of Integrated Resource Planning (IRP) and subsequently to a hybrid of competition and IRP began and is continuing on the state and regional level. Local success stories on the West Coast and New England persuaded other states to adopt these methods. This strategy could also prove to be very effective in regions of Russia that are served by integrated electricity grids, such as the South Russia Power pool (Yuzhenergo) that serves the North Caucasus region. As the Russian energy system currently undergoes change, simultaneously privatizing and restructuring, these issues will be largely decided within the next two years. One of the greatest challenges involves implementing an environmentally sustainable strategy which ensures that energy efficiency and renewable energy are incorporated into the new structure.

    This Heat Management Trade Study was performed in 2008-2009 to expand on prior studies in continued efforts to analyze and evaluate options for cost-effectively managing SNF reprocessing wastes. The primary objective was to develop a simplified cost/benefit evaluation for spent nuclear fuel (SNF) reprocessing that combines the characteristics of the waste generated through reprocessing with the impacts of the waste on heating the repository. Under consideration were age of the SNF prior to reprocessing, plutonium and minor actinide (MA) separation from the spent fuel for recycle, fuel value of the recycled Pu and MA, age of the remaining spent fuel waste prior to emplacement in the repository, length of time that active ventilation is employed in the repository, and elemental concentration and heat limits for acceptable glass waste form durability. A secondary objective was to identify and qualitatively analyze remaining issues such as (a) impacts of aging SNF prior to reprocessing on the fuel value of the recovered fissile materials, and (b) impact of reprocessing on the dose risk as developed in the Yucca Mountain Total System Performance Assessment (TSPA). Results of this study can be used to evaluate different options for managing decay heat in waste streams from spent nuclear fuel.

    Mamun, Abdullah Al

    The main aim of this thesis is to explore machining strategies, analyzing energy consumption using Design of Experiments (DOE) at the material removal rate (MRR), compare to cutting geometrical trajectories according to CNC parameters such as spindle RPM, feed rate, depth of cut per pass and total depth of cut. Spindle RPM, depth of cut per pass, and feed rate are selected as the main three factors and each factor has two levels: low-level (-) and high-level (+). These experiments have been performed at an end-milling machine by using a concept of a constant volume of material removal processes in the circular and linear geometrical slots in pine wood blocks. Standard energy logger equipment has used to measure energy consumption during end-milling operation. Different statistical analysis, such as ANOVA, regression line, and cause & effect diagram have used to show different energy consumption results in the material removal process. At the end the of data analysis, it is found that a significant amount of electricity demand is associated with machining pre-cutting & post-cutting stage and this significant amount of electricity demand is defined as peripheral energy. This peripheral energy is not involved in the actual performance of material removal process in the end-milling process. In the [Figure 11] end-milling process has been involved with pine wood blocks at constant volume of material removal (2.8 cubic inch) process. Results can be varied using of hard material removal process, such as steel & aluminum metals.

    Energy Technology Data Exchange (ETDEWEB)

    Firestone, Ryan; Marnay, Chris

    2005-01-01

    On-site energy production, known as distributed energy resources (DER), offers consumers many benefits, such as bill savings and predictability, improved system efficiency, improved reliability, control over power quality, and in many cases, greener electricity. Additionally, DER systems can benefit electric utilities by reducing congestion on the grid, reducing the need for new generation and transmission capacity, and offering ancillary services such as voltage support and emergency demand response. Local aggregations of distributed energy resources (DER) that may include active control of on-site end-use energy devices can be called microgrids. Microgrids require control to ensure safe operation and to make dispatch decisions that achieve system objectives such as cost minimization, reliability, efficiency and emissions requirements, while abiding by system constraints and regulatory rules. This control is performed by an energy manager (EM). Preferably, an EM will achieve operation reasonably close to the attainable optimum, it will do this by means robust to deviations from expected conditions, and it will not itself incur insupportable capital or operation and maintenance costs. Also, microgrids can include supervision over end-uses, such as curtailing or rescheduling certain loads. By viewing a unified microgrid as a system of supply and demand, rather than simply a system of on-site generation devices, the benefits of integrated supply and demand control can be exploited, such as economic savings and improved system energy efficiency.

    Full Text Available The Smart Grid vision imposes a new approach towards energy supply that is more affordable, reliable and sustainable. The core of this new vision is the use of advanced technology to monitor power system dynamics in real time and identify system in stability. In order to implement strategic vision for energy management, it is possible to identify three main areas of investigation such as smart generation, smart grid and smart customer. Focusing on the latter topic, in this paper we present an application specifically designed to monitor an industrial site with particular attention to power consumption. This solution is a real time analysis tool, able to produce useful results to have a strategic approach in the energy market and to provide statistic analysis useful for the future choices of the industrial company. The application is based on a three layers architecture. The technological layer uses a Wireless Sensor Network (WSN to acquire data from the electrical substations. The middleware layer faces the integration problems by processing the raw data. The application layer manages the data acquired from the sensors. This WSN based architecture represents an interesting example of a low cost and non-invasive monitoring application to keep the energy consumption of an industrial site under control. Some of the added value features of the proposed solution are the routing network protocol, selected in order to have an high availability of the WSN, and the use of the WhereX middleware, able to easily implement integration among the different architectural parts.

The paper reflects on the energy performance of the campus since its operation in 2001, based on 14 years of energy data and a detailed record of all initiatives undertaken by the campus’s facilities management (FM team in order to optimise energy performance. The integrated FM strategy composed of low- and no-cost strategies, continuous improvements, ongoing commissioning and retrofits succeeded in reducing campus energy intensity from 174 to 87 kWh/(m2*yr, now outperforming most relevant benchmarks. This finding highlights the importance of operations and maintenance in reducing the energy usage of existing buildings. This presented findings draw on a single case only, which excels through a very detailed longitudinal dataset. Going forwards, the analysis of further cases is recommended to corroborate the findings. The presented results suggest that proactive operations and maintenance strategies in existing buildings can contribute towards significantly improving energy performance. The profile and competency level of facilities management personnel should consequently be raised strategically at the organisational and national/industrial policy level, whilst integrated design processes should be further expanded to include FM’s operational control and management in a holistically fashion.

    Full Text Available This article introduces the proposal of discrete model of district heating and cooling system (DHC for energy flow optimization. The aim is to achieve the best solution of the objective function, usually determined by minimizing the production and distribution costs and providing meets the needs of energy consumers. The model also introduces the idea of general prosumers strategy, where all active elements within the modern DHC system are representing by prosumers object. The prosumers are perceived as objects able to actively participate in the planning of production and consumption of energy. It is assumed that the general behaviour of the object in DHC is the same, no matter how they differ in sizes and designs. Thus, all the objects are defined by two characteristics - the ability to produce and consume. The model based on this basic principle, of course, with the most accurate information about the particular values at a time, object properties and other, should provide tools for simulation and control of modern DHC, possibly superior units as Smart Energy Grids - understood as a system integrating Smart Grids (electricity and Smart Thermal Grids (heat a cool.

    Iden, Ronald

    The multigenerational workforce presents a critical challenge for business managers, and each generation has different expectations. A human resource management study of organizations with more than 500 employees reported 58% of the managers experiencing conflict between younger and older workers. The purpose of this single case study was to explore the multigenerational strategies used by 3 managers from a Franklin County, Ohio manufacturing facility with a population size of 6 participants. The conceptual framework for this study was built upon generational theory and cohort group theory. The data were collected through face-to-face semistructured interviews, company documents, and a reflexive journal. Member checking was completed to strengthen the credibility and trustworthiness of the interpretation of participants' responses. A modified van Kaam method enabled separation of themes following the coding of data. Four themes emerged from the data: (a) required multigenerational managerial skills, (b) generational cohort differences, (c) most effective multigenerational management strategies, and (d) least effective multigenerational management strategies. Findings from this study may contribute to social change through better understanding, acceptance, and appreciation of the primary generations in the workforce, and, in turn, improve community relationships.

  7. Strategies for successful software development risk management

    Directory of Open Access Journals (Sweden)

    Marija Boban

    2003-01-01

    Full Text Available Nowadays, software is becoming a major part of enterprise business. Software development is activity connected with advanced technology and high level of knowledge. Risks on software development projects must be successfully mitigated to produce successful software systems. Lack of a defined approach to risk management is one of the common causes for project failures. To improve project chances for success, this work investigates common risk impact areas to perceive a foundation that can be used to define a common approach to software risk management. Based on typical risk impact areas on software development projects, we propose three risk management strategies suitable for a broad area of enterprises and software development projects with different amounts of connected risks. Proposed strategies define activities that should be performed for successful risk management, the one that will enable software development projects to perceive risks as soon as possible and to solve problems connected with risk materialization. We also propose a risk-based approach to software development planning and risk management as attempts to address and retire the highest impact risks as early as possible in the development process. Proposed strategies should improve risk management on software development projects and help create a successful software solution.

    Energy Technology Data Exchange (ETDEWEB)

    Saintherant, N.; Lerouge, Ch.; Welcker, A

    2008-01-15

    In the present day situation of sudden awareness about climatic change and announced fossil fuels shortage, Ireland has defined a new strategy for its energy future. Context: Ireland is strongly dependent of oil and gas imports which increase regularly to meet the demand. A small part of the electricity consumed is imported from Ulster. The share of renewable energies remains weak but is increasing significantly. Therefore, from 1990 to 2006, the proportion of renewable energies increased from 1.9% (mainly of hydroelectric origin) to 4.5%. Wind power represents now the main renewable energy source. The transportation sector is the most energy consuming and the biggest source of greenhouse gases. Strategy: the Irish policy is driven by pluri-annual strategic plans which define the objectives and means. Priority is given to the security of supplies at affordable prices: 8.5 billion euros will be invested during the 2007-2013 era for the modernization of existing energy infrastructures and companies, and in a lesser extent for the development of renewable energy sources. During this period, 415 million euros more will be devoted to the research, development and demonstration (RD and D) of new energy solutions. Research: in 2005 the energy RD and D expenses reached 12.8 million euros shared between 54% for R and D and 46% for demonstration projects. Half of the financing is given to higher education schools and is devoted to energy saving purposes (33%) and to renewable energies (29%, mainly wind power and biomass). Academic research gives a particular attention to ocean energy which represents an important potential resource in Ireland and which has already led to the creation of innovative companies. The integration of renewable energy sources to the power grid and the stability of supplies are also the object of active researches. (J.S.)

    2015-01-01

    Overwork, at first glance, seems like a problem that affects only the employee. But for medical practices and those who manage them, the problem is far greater than that. Chronically overworked employees may not be meeting their goals. They may be making more mistakes and letting things slip through the cracks. Ultimately, patients may have less-than-ideal experiences in a practice where the employees are stretched thin. And turnover may skyrocket in practices where employees are chronically overworked. This article offers practice managers 20 practical and affordable strategies they can use to manage a chronically overworked medical practice team. It suggests an effective technique they can use to tell their bosses that their employees are overworked. This article also suggests the costs to the practice of a chronically overworked staff, including a hidden cost many people overlook. It provides four coping strategies practice managers can teach to their overworked employees. It summarizes research exploring how overwork affects employees' sleep and eating habits, and additional research linking long hours of overwork to diminished productivity. Finally, this article provides five strategies practice managers can use to make their overworked employees feel valued.

    2016-12-01

    NOAA's Pacific Marine Environmental Laboratory (PMEL) hosts a wide range of scientific projects that span a number of scientific and environmental research disciplines. Each of these 14 research projects have their own data streams that are as diverse as the research. With its requirements for public access to federally funded research results and data, the 2013 White House Office of Science and Technology memo on Public Access to Research Results (PARR) changed the data management landscape for Federal agencies. In 2015, with support from the PMEL Director, Dr. Christopher Sabine, PMEL's Science Data Integration Group (SDIG) initiated a multi-year effort to formulate and implement an integrated data-management strategy for PMEL research efforts. Instead of using external requirements, such as PARR, to define our approach, we focussed on strategies to provide PMEL science projects with a unified framework for data submission, interoperable data access, data storage, and easier data archival to National Data Centers. This improves data access to PMEL scientists, their collaborators, and the public, and also provides a unified lab framework that allows our projects to meet their data management objectives, as well as those required by the PARR. We are implementing this solution in stages that allows us to test technology and architecture choices before comitting to a large scale implementation. SDIG developers have completed the first year of development where our approach is to reuse and leverage existing frameworks and standards. This presentation will describe our data management strategy, explain our phased implementation approach, the software and framework choices, and how these elements help us meet the objectives of this strategy. We will share the lessons learned in dealing with diverse and complex datasets in this first year of implementation and how these outcomes will shape our decisions for this ongoing effort.

  1. Load Reduction, Demand Response and Energy Efficient Technologies and Strategies

    Energy Technology Data Exchange (ETDEWEB)

    Boyd, Paul A.; Parker, Graham B.; Hatley, Darrel D.

    2008-11-19

    The Department of Energy’s (DOE’s) Pacific Northwest National Laboratory (PNNL) was tasked by the DOE Office of Electricity (OE) to recommend load reduction and grid integration strategies, and identify additional demand response (energy efficiency/conservation opportunities) and strategies at the Forest City Housing (FCH) redevelopment at Pearl Harbor and the Marine Corps Base Hawaii (MCBH) at Kaneohe Bay. The goal was to provide FCH staff a path forward to manage their electricity load and thus reduce costs at these FCH family housing developments. The initial focus of the work was at the MCBH given the MCBH has a demand-ratchet tariff, relatively high demand (~18 MW) and a commensurate high blended electricity rate (26 cents/kWh). The peak demand for MCBH occurs in July-August. And, on average, family housing at MCBH contributes ~36% to the MCBH total energy consumption. Thus, a significant load reduction in family housing can have a considerable impact on the overall site load. Based on a site visit to the MCBH and meetings with MCBH installation, FCH, and Hawaiian Electric Company (HECO) staff, recommended actions (including a "smart grid" recommendation) that can be undertaken by FCH to manage and reduce peak-demand in family housing are made. Recommendations are also made to reduce overall energy consumption, and thus reduce demand in FCH family housing.

    2017-02-01

    This paper presents a comprehensive review of power management strategy (PMS) utilized in hybrid electric vehicles (HEVs) with an emphasis on model predictive control (MPC) based strategies for the first time. Research on MPC-based power management systems for HEVs has intensified recently due to its many inherent merits. The categories of the existing PMSs are identified from the latest literature, and a brief study of each type is conducted. Then, the MPC approach is introduced and its advantages are discussed. Based on the acquisition method of driver behavior used for state prediction and the dynamic model used, the MPC is classified and elaborated. Factors that affect the performance of the MPC are put forward, including prediction accuracy, design parameters, and solvers. Finally, several important issues in the application of MPC-based power management strategies and latest developing trends are discussed. This paper not only provides a comprehensive analysis of MPC-based power management strategies for HEVs but also puts forward the future and emphasis of future study, which will promote the development of energy management controller with high performance and low cost for HEVs.

    The adoption of the Balanced Scorecard philosophy of measure, monitor and manage by The Hospital for Sick Children (SickKids) has resulted in SickKids' staff understanding, appreciating and ultimately being able to accept the enhanced transparency and accountability around performance, at both the system and hospital levels. The leadership of the organization observed these differences after initial SickKids scorecard update meetings, realizing this was not a flavour of the month but a totally new way of operating in a quest to achieve SickKids' vision and mission. Almost immediately, the internal culture began to shift as staff better understood how their roles actively contribute to the organization's ability to execute on its strategy. Based on 2010 staff engagement results, 70% of staff "see a direct link between personal work objectives and SickKids' strategy," while 60% were familiar with the newly released strategic plan, unprecedented results based on current benchmarks. This article provides an overview of the SickKids strategy management system, outlining both best practices and the journey from its launch to induction into the Balanced Scorecard Hall of Fame. Performance, at all levels across the enterprise, has shown measureable improvement with the introduction of the comprehensive strategy management system.

    Full Text Available Background: Unlike Enterprise Risk Management, which is certainly quite well rooted in business practice, Supply Chain Risk Management (SCRM still continues to be dynamically developing subject of academic research, whereas its practical applications are rather scarce. Material and methods: On the basis of broad review of the current state of the art in world literature, significant  relevancies to the core processes and enterprise strategy are discussed.   Results: The paper shows some interesting from the enterprise's performance and competitiveness point of view additional benefits, potentially resulting from the proactive, consistent and effective implementation of the SCRM system. Conclusions: Some additional advantages from proactive supply chain risk management account for perceiving SCRM as multifunctional instrument of strategic SC management, exceeding established understanding RM as security and threat-prevention  tool only. Positive influence from SCRM onto SC performance and competitiveness can make reasonable to enhance its position within SCM strategy.

    Full Text Available Energy efficient computing has recently become hot research area. Many works have been carried out on conserving energy, but considering energy efficiency in grid computing is few. This paper proposes energy efficient resource management in mobile grid. The objective of energy efficient resource management in mobile grid is to maximize the utility of the mobile grid which is denoted as the sum of grid application utility. The utility function models benefits of application and system. By using nonlinear optimization theory, energy efficient resource management in mobile grid can be formulated as multi objective optimization problem. In order to derive a distributed algorithm to solve global optimization problem in mobile grid, we decompose the problem into the sub problems. The proposed energy efficient resource management algorithm decomposes the optimization problem via iterative method. To test the performance of the proposed algorithm, the simulations are conducted to compare proposed energy efficient resource management algorithm with other energy aware scheduling algorithm.

    The IEA Policy Pathway publications provide details on how to implement specific recommendations drawn from the IEA 25 Energy Efficiency Policy Recommendations. This Policy Pathway, jointly produced by the International Energy Agency and the Institute for Industrial Productivity, develops the critical steps for policy makers implementing energy management programmes for industry. Optimising energy use in industry is essential to improve industrial competitiveness and achieve wider societal goals such as energy security, economic recovery and development, climate change mitigation and environmental protection.While there is significant potential to decrease energy consumption in this sector, opportunities to improve energy efficiency are still under-exploited. Energy management programmes have shown to be instrumental in addressing many of the barriers that inhibit wide-scale uptake of energy management in industry. The Policy Pathway builds on lessons learned from country experiences and provides actionable guidance on how to plan and design, implement, evaluate and monitor energy management programmes for industry.

  13. Energy management and vehicle synthesis

    Science.gov (United States)

    Czysz, P.; Murthy, S. N. B.

    The major drivers in the development of launch vehicles for the twenty-first century are reduction in cost of vehicles and operations, continuous reusability, mission abort capability with vehicle recovery, and readiness. One approach to the design of such vehicles is to emphasize energy management and propulsion as being the principal means of improvements given the available industrial capability and the required freedom in selecting configuration concept geometries. A methodology has been developed for the rational synthesis of vehicles based on the setting up and utilization of available data and projections, and a reference vehicle. The application of the methodology is illustrated for a single stage to orbit (SSTO) with various limits for the use of airbreathing propulsion.

    Full Text Available There has been a continuous growth in ecological agriculture (EA in recent years. It is recognized as a production system with rational energy use and low demand for fossil fuels. There are many studies relating to this subject, in contrast to the few studies regarding the use of energy and its impact on the environment in ecological greenhouses. This article analyzes the strategies adopted by a Transformational Agricultural Society (Sociedad Agraria de Transformación in order to improve energy efficiency in ecological greenhouses, with regards to the use of fossil fuels. The methodology is based on the Working With People (WWP Model, which involves social learning processes over 30 years in one of the largest regions of ecological crops in Spain. The results show that the measures taken to manage the greenhouses have achieved a decrease of over 80% in terms of fossil fuel consumption. The experience demonstrates that EA, as opposed to conventional agriculture (CA, is a system with great potential when it comes to reducing energy consumption and environmental improvements through various strategies.

  15. Research on Factors Influencing Individual's Behavior of Energy Management

    Science.gov (United States)

    Fan, Yanfeng

    With the rapid rise of distributed generation, Internet of Things, and mobile Internet, both U.S. and European smart home manufacturers have developed energy management solutions for individual usage. These applications help people manage their energy consumption more efficiently. Domestic manufacturers have also launched similar products. This paper focuses on the factors influencing Energy Management Behaviour (EMB) at the individual level. By reviewing academic literature, conducting surveys in Beijing, Shanghai and Guangzhou, the author builds an integrated behavioural energy management model of the Chinese energy consumers. This paper takes the vague term of EMB and redefines it as a function of two separate behavioural concepts: Energy Management Intention (EMI), and the traditional Energy Saving Intention (ESI). Secondly, the author conducts statistical analyses on these two behavioural concepts. EMI is the main driver behind an individual's EMB. EMI is affected by Behavioural Attitudes, Subjective Norms, and Perceived Behavioural Control (PBC). Among these three key factors, PBC exerts the strongest influence. This implies that the promotion of the energy management concept is mainly driven by good application user experience (UX). The traditional ESI also demonstrates positive influence on EMB, but its impact is weaker than the impacts arising under EMI's three factors. In other words, the government and manufacturers may not be able to change an individual's energy management behaviour if they rely solely on their traditional promotion strategies. In addition, the study finds that the government may achieve better promotional results by launching subsidies to the manufacturers of these kinds of applications and smart appliances.

    2015-01-01

    We develop an analytical approach for more systematically analyzing environmental management problems in order to develop strategic plans. This approach can be deployed by agencies, non-profit organizations, corporations, or other organizations and institutions tasked with improving environmental quality. The analysis relies on assessing the underlying natural processes followed by articulation of the relevant societal forces causing environmental change: (1) science and technology, (2) governance, (3) markets and the economy, and (4) public behavior. The four forces analysis is then used to strategize which types of actions might be most effective at influencing environmental quality. Such strategy has been under-used and under-valued in environmental management outside of the corporate sector, and we suggest that this four forces analysis is a useful analytic to begin developing such strategy.

    Gunasekaran, S

    1986-01-01

    Grain drying is very specific to the geographic location, kind of drying system, and the type of grain. Under a given set of conditions, the optimal system can be selected based on careful evaluation. However, a good choice of drying systems, procedures, and management practices can be made from the information already available. The review of several grain-drying procedures has provided some insight in making a quick evaluation of the process and arriving at the most suitable system for a particular application. Despite extensive research efforts, the present knowledge of grain drying is yet insufficient to optimally design each drying process with respect to capacity, quality, and energy requirement. There is a need for incorporating grain and air parameters more accurately. It is also important to develop comprehensive drying simulation models to encompass agronomic practices, such as planting and harvesting. Recent efforts indicate a strong influence of planting and harvesting strategies on optimal drying and storage system selection. Results of the varietal trials at Ohio State University indicate that it is now possible to select midseason varieties, which dry down rapidly, without sacrificing yield. Also, low moisture at harvest is important to the energy management process because it affects total drying time and energy required. It is also important from a quality standpoint because kernel damage increases rapidly at harvesting moisture levels above 25%. The trend in grain-dryer design has shifted from focusing on drying capacity and operation reliability to energy consumption. The development in design of energy efficient continuous-flow dryers has been significant. Multistage concurrentflow dryers are excellent examples. Various aspects of dryer staging for efficient operation and control are yet to be determined. Recirculation of the exhaust air is a proven method of improving energy efficiency. Likewise, in batch-in-bin systems, stirring and

    In many agricultural regions of the world, aquifer overdrafting for agricultural irrigation continues. Management strategies are investigated that transition from this unsustainable use of water to a future, diminished use of irrigation. Complications arising from climate change and volatile energy prices are considered. A command and control strategy is modeled using combined simulation and optimization techniques. This strategy is compared with market based mechanisms such as cap and trade and Pigouvian pricing that are modeled using agent based methods. The formulations are designed to model the effects of different management strategies including those that seek to avoid rapid changes in basin-wide water utilization (considered a surrogate for agricultural production) over this time period. Formulations also include limits on total reduction in aquifer storage and controls on streamflow in the basin. The management formulations used in this study are developed for planning horizons of 50 to 100 years and use the Republican River Basin in the High Plains Aquifer as a case study. Historical and climate-adjusted recharge patterns are considered. Spatial and temporal variation in total irrigated acreage and the aquifer storage change determined by the solutions of the management formulations are analyzed and presented.

    The increasing requirement of transmission network sizes would result in huge energy consumption with communication traffic. Green communication technologies are expected to help in reducing energy consumption impact to environment. Therefore, it is important to design energy-efficient strategy that can decrease energy consumption. This paper proposes to use the acquaintance and improved targeted immunization strategies from complex systems to resolve energy consumption issues and uses traffic as measure standard to obtain a stable threshold. The simulation results show that the improved control strategy is better and more effective to save as much energy as possible.

    In power systems, energy storage effectively improves the reliability of the system and smooths out the fluctuations of intermittent energy. However, the installed capacity value of energy storage cannot effectively measure the contribution of energy storage to the generator adequacy of power systems. To achieve a variety of purposes, several control strategies may be utilized in energy storage systems. The purpose of this paper is to study the influence of different energy storage control strategies on the generation adequacy. This paper presents the capacity value of energy storage to quantitatively estimate the contribution of energy storage on the generation adequacy. Four different control strategies are considered in the experimental method to study the capacity value of energy storage. Finally, the analysis of the influence factors on the capacity value under different control strategies is given.

    Ghanem, Mohamed

    2015-06-01

    Full Text Available Background: Instead of waiting for challenges to confront hospital management, doctors and managers should act in advance to optimize and sustain value-based health. This work highlights the importance of scenario planning in hospitals, proposes an elaborated definition of the stakeholders of a hospital and defines the influence factors to which hospitals are exposed to. Methodology: Based on literature analysis as well as on personal interviews with stakeholders we propose an elaborated definition of stakeholders and designed a questionnaire that integrated the following influence factors, which have relevant impact on hospital management: political/legal, economic, social, technological and environmental forces. These influence factors are examined to develop the so-called critical uncertainties. Thorough identification of uncertainties was based on a “Stakeholder Feedback”. Results: Two key uncertainties were identified and considered in this study: According to the developed scenarios, complementary education of the medical staff as well as of non-medical top executives and managers of hospitals was the recommended core strategy. Complementary scenario-specific strategic options should be considered whenever needed to optimize dealing with a specific future development of the health care environment. Conclusion: Strategic planning in hospitals is essential to ensure sustainable success. It considers multiple situations and integrates internal and external insights and perspectives in addition to identifying weak signals and “blind spots”. This flows into a sound planning for multiple strategic options. It is a state of the art tool that allows dealing with the increasing challenges facing hospital management.

    1984-01-01

    The thermal energy management processes experiment (TEMP) will demonstrate that through the use of two-phase flow technology, thermal systems can be significantly enhanced by increasing heat transport capabilities at reduced power consumption while operating within narrow temperature limits. It has been noted that such phenomena as excess fluid puddling, priming, stratification, and surface tension effects all tend to mask the performance of two-phase flow systems in a 1-g field. The flight experiment approach would be to attack the experiment to an appropriate mounting surface with a 15 to 20 meter effective length and provide a heat input and output station in the form of heaters and a radiator. Using environmental data, the size, location, and orientation of the experiment can be optimized. The approach would be to provide a self-contained panel and mount it to the STEP through a frame. A small electronics package would be developed to interface with the STEP avionics for command and data handling. During the flight, heaters on the evaporator will be exercised to determine performance. Flight data will be evaluated against the ground tests to determine any anomalous behavior.

    Full Text Available The shipping sector is facing new challenges in energy consumption and management. In a recent study conducted by the European Sea Ports Organization (ESPO has shown that energy consumption has risen from 7th place in 2009, to 2nd in 2016, as far as the 10 environmental priorities of European ports. Energy management is seen as the greatest risk for shipping companies, due to the variability existing in the oil and gas markets, in recent decades. Unsuccessful energy management strategies have been shown to have serious consequences for the natural environment, as well as for the companies themselves, which include the enhancement of global warming, and the destruction of a positive corporate image/reputation. Due to this, shipping companies now consider energy as an integral part of their overall strategy and adopt risk management assessments in order to attain the best returns on their investments. The ISO 50001 standard provides a useful tool to companies that are eager to develop and apply an efficient energy strategy consistent with modern Social Corporate Responsibility requirements and aspirations.

    The global healthcare burden attributable to heart failure is ever increasing. Patients presenting with refractory heart failure should be evaluated for compliance with medical regimens and sodium and/or fluid restriction, and every attempt should be made to optimize conventional strategies. Reversible causes such as ischemia should be identified and revascularization considered in persistently symptomatic patients, particularly those with a viable myocardium. Carefully selected patients who continue to deteriorate clinically in spite of optimization of medical therapy may be considered for advanced treatment strategies, such as continuous inotropic infusions, mechanical circulatory support devices, cardiac transplantation, or referral to hospice care. We discuss the clinical presentation and management of patients with advanced/refractory (Stage D) heart failure.

  1. Strategies for risk management in cancer nursing.

    Science.gov (United States)

    Chamorro, T; Tarulli, D

    1990-01-01

    In the current social and legal climate, nurses are increasingly subject to litigation charging professional negligence. A higher professional standing for nursing and a larger role in the decision-making aspects of health care have helped to effect this revolution. There are inherent risks in providing health care that are intensified by the rapid growth in medical technology and complex treatment. Claims brought against nurses have been categorized in studies, and primary causes of patient injury in the healthcare facility are also identified. Using these and other data, areas within cancer nursing that predispose to the risk of increased liability can be anticipated. Issues that are unique to the acute care, ambulatory, or homecare setting in oncology are described. Risk management is a mechanism that addresses the prevention and control of financial loss resulting from claims of negligence. Using risk management concepts, strategies are developed to help the cancer nurse recognize intrinsic dangers and reduce the potential for liability.

    2015-09-09

    PROBLEM/BACKGROUND: Pain management is a major worldwide health problem. It manifests itself in a variety of forms involving in turn a multiplicity of responses and therapeutic strategies. Following from this, the training of health personnel must deal with this situation and must not only offer technical assistance, but must also deal with the psychological and social aspects of the problem. In recent years various guidelines and protocols have become popular for pain management. The aim of this paper is to present a literature review of the major international databases. Type of research: Systematic review. To identify relevant studies in the literature on pain management and identify the guidelines recognized by the scientific community. A literature search was conducted using the keywords "pain management" and "nurse" published since 2000 in English and Italian in the following databases: PubMed, CINAHL, Med Line. Excluding items which did not meet the inclusion criteria, 49 articles were included in the review. Despite a growing availability of evidence-based guidelines, drugs for pain control and the enactment of legislation to promote the use of opioid analgesics in pain therapy, a substantial proportion of the European population continues to have pain. Estimates of the prevalence of pain symptoms in the literature show that between 40% and 63% of hospitalized patients reported pain, peaking at 82.3% in cancer patients in advanced stages of the disease or terminally ill (in hospital or at home). Several studies published in recent years have agreed on a definition of some key points in the management of pain. Studies agree that pain should be recognized as the 5th vital sign, hence the need for validated scales whether single or multi-dimensional, quantitative or qualitative. The approach to the management of pain must be multi-professional, and the use of pharmacology must be in accordance with the WHO three-step approach. Several studies have demonstrated

  3. Robust Control of Aeronautical Electrical Generators for Energy Management Applications

    Directory of Open Access Journals (Sweden)

    Giacomo Canciello

    2017-01-01

    Full Text Available A new strategy for the control of aeronautical electrical generators via sliding manifold selection is proposed, with an associated innovative intelligent energy management strategy used for efficient power transfer between two sources providing energy to aeronautical loads, having different functionalities and priorities. Electric generators used for aeronautical application involve several machines, including a main generator and an exciter. Standard regulators (PI or PID-like are normally used for the rectification of the generator voltage to be used to supply a high-voltage DC bus. The regulation is obtained by acting on a DC/DC converter that imposes the field voltage of the exciter. In this paper, the field voltage is fed to the generator windings by using a second-order sliding mode controller, resulting into a stable, robust (against disturbances action and a fast convergence to the desired reference. By using this strategy, an energy management strategy is proposed that dynamically changes the voltage set point, in order to intelligently transfer power between two voltage busses. Detailed simulation results are provided in order to show the effectiveness of the proposed energy management strategy in different scenarios.

    Full Text Available The states from European Union must take advantage from renewable energy sources in order to revive the economy. Climate change creates new jobs and could reduce energy imports which would stimulate the economy of those states. The European Union should support research in the field, apply more efficient policies in energy, and create economies of scale to get an integrated European energy market in which the main actors can reduce the cost of production of renewable energy. In addition, it is possible to use the comparative advantages of the Member States and not only, like Greece, through solar energy, Southern Mediterranean, through distribution networks interconnections with EU, Russia and Ukraine, through biomass and the North Sea, through wind energy. This paper refers to the evolution and trends of the renewable energy sources and presents some scenarios of it.

    2013-01-01

    India has one of the highest incidences of oral cancer and accounts for about 30% of all new cases annually. A high prevalence of smokeless tobacco use has led to an increasing incidence, which in combination with delayed presentation has made oral cancer a major health problem in India. Limited access to cancer care, relative lack of trained healthcare providers and financial resources are some of the challenges to the management of oral cancer in India despite improvements in diagnostic techniques and management strategies. We reviewed the literature pertaining to the epidemiology, aetiopathogenesis, pre-malignancy, tumour progression, management of the primary site, mandible, neck lymph node metastases, reconstruction options and screening of oral cancer. The parameters evaluated were overall survival, disease-free survival, recurrence and loco-regional control. Nine studies on surgical intervention were reviewed. There were 23 studies on the management of chemotherapy and 30 trials analysing radiotherapy as an intervention. India has one of the highest incidences of oral cancer and delayed stage presentation is common. Surgery remains the treatment of choice and adjuvant treatment is recommended in high-risk patients. Elective neck dissection is warranted in clinically lymph node-negative neck for patients with thick tumours, imaging-suspected lymph nodes and those who may not have a reliable follow-up. Functional outcomes and treatment-related morbidity needs to be considered, and reconstruction with free tissue transfer provides the best results. Copyright 2013, NMJI.

    CLN2 disease (neuronal ceroid lipofuscinosis type 2) is a rare, autosomal recessive, pediatric-onset, rapidly progressive neurodegenerative lysosomal storage disorder caused by tripeptidyl peptidase 1 (TPP1) enzyme deficiency, and is characterized by language delay, seizures, rapid cognitive and motor decline, blindness, and early death. No management guidelines exist and there is a paucity of published disease-specific evidence to inform clinical practice, which currently draws upon experience from the field of childhood neurodisability. Twenty-four disease experts were surveyed on CLN2 disease management and a subset met to discuss current practice. Management goals and strategies are consistent among experts globally and are guided by the principles of pediatric palliative care. Goals and interventions evolve as the disease progresses, with a shift in focus from maintenance of function early in the disease to maintenance of quality of life.

    2004-03-01

    Kolter Property Management Ltd., which manages office buildings across North America, is committed to energy efficiency. The company implements systems that save energy and make use of waste heat in office buildings. Kolter's Ontario Hydro Place was the most energy efficient building in the world when it was built in 1975. Kolter joined the Energy Innovators Initiative (EII) in 1999. The program helps commercial businesses and public institutions improve their energy efficiency and reduce greenhouse gas (GHG) emissions. Kolter's goal is to reduce energy consumption and GHG emissions by 15 per cent below 1990 levels by 2005. The strategies include: improve efficiency through low-cost opportunities such as good operating and maintenance practices; reduce energy operating costs by initiating an energy retrofit program that will reduce GHG emissions; improve energy efficiency through capital upgrades; and, work with EII to reduce the overall energy consumption of its properties. This paper describes the efforts that Kolter made at Canada Square in Toronto where an energy bill of nearly $3 million was reduced through energy upgrades such as electronic ballasts, light reflector systems, T-8 lamps, new and upgraded HVAC systems, and a sub-metering system. The retrofit project saved 17.3 per cent energy and $503,264 in annual energy bills. GHGs were reduced by 3,681 tonnes per year. 1 tab., 3 figs.

    Thirty-five years after the Agency's founding, the IEA responsibility for ensuring access to global oil supplies is still a core mandate -- but new energy-related concerns have arisen. Energy security is no longer only about oil. And the industrialised nations of the world are no longer the only major consumers of energy. Climate change driven by greenhouse gas emissions -- 60% of which derive from energy production or use -- is a growing threat. So energy policy was tasked with a new objective: to cut greenhouse gas emissions while maintaining economic growth.

  15. Strategic Energy Management Plan For Fort Buchanan, Puerto Rico

    2001-10-31

    This document reports findings and recommendations as a result of a design assistance project with Fort Buchanan with the goals of developing a Strategic Energy Management Plan for the Site. A strategy has been developed with three major elements in mind: 1) development of a strong foundation from which to build, 2) understanding technologies that are available, and 3) exploring financing options to fund the implementation of improvements. The objective of this report is to outline a strategy that can be used by Fort Buchanan to further establish an effective energy management program. Once a strategy is accepted, the next step is to take action. Some of the strategies defined in this Plan may be implemented directly. Other strategies may require the development of a more sophisticated tactical, or operational, plan to detail a roadmap that will lead to successful realization of the goal. Similarly, some strategies are not single events. Rather, some strategies will require continuous efforts to maintain diligence or to change the culture of the Base occupants and their efforts to conserve energy resources.

    Almost 40 years after the Agency’s founding, the IEA responsibility for ensuring access to global oil supplies is still a core mandate. Yet over the course of its history, the IEA’s responsibilities have expanded along with both the international energy economy and conceptions of energy security itself. Our mission to promote secure and sustainable energy provision spans the energy mix. At the same time, a changing global energy map means that the industrialised nations of the world no longer dominate energy consumption. The IEA must work in close co-operation with partner countries and organisations worldwide to achieve its three core objectives: energy security, economic prosperity, and environmental sustainability. Working toward international commitments to reduce greenhouse gas emissions that cause global climate change; facilitating energy technology exchange, innovation and deployment; improving modern energy access to the billions of people who are without it; bolstering both cleanliness and security through energy efficiency; and promoting flexible and functioning energy markets – these efforts complement our traditional core responsibilities of mitigating the effects of supply disruptions and improving statistical transparency.

  17. Forest management strategies for reducing carbon emissions, the French case

    Valade, Aude; Luyssaert, Sebastiaan; Bellassen, Valentin; Vallet, Patrick; Martin, Manuel

    2015-04-01

    International agreements now recognize the role of forest in the mitigation of climate change through the levers of in-situ sequestration, storage in products and energy and product substitution. These three strategies of carbon management are often antagonistic and it is still not clear which strategy would have the most significant impact on atmospheric carbon concentrations. With a focus on France, this study compares several scenarios of forest management in terms of their effect on the overall carbon budget from trees to wood-products. We elaborated four scenarios of forest management that target different wood production objectives. One scenario is 'Business as usual' and reproduces the current forest management and wood production levels. Two scenarios target an increase in bioenergy wood production, with either long-term or short-term goals. One scenario aims at increasing the production of timber for construction. For this, an empirical regression model was developed building on the rich French inventory database. The model can project the current forest resource at a time horizon of 20 years for characteristic variables diameter, standing volume, above-ground biomass, stand age. A simplified life-cycle analysis provides a full carbon budget for each scenario from forest management to wood use and allows the identification of the scenario that most reduces carbon emissions.

    This review considers management strategies (combinations of initial investigation and empirical treatments) for dyspeptic patients. Dyspepsia was defined to include both epigastric pain and heartburn. To determine the effectiveness, acceptability, and cost effectiveness of the following initial management strategies for patients presenting with dyspepsia (a) Initial pharmacological therapy (including endoscopy for treatment failures). (b) Early endoscopy. (c) Testing for Helicobacter pylori (H. pylori )and endoscope only those positive. (d) H. pylori eradication therapy with or without prior testing. Trials were located through electronic searches and extensive contact with trialists. All randomised controlled trials of dyspeptic patients presenting in primary care. Data were collected on dyspeptic symptoms, quality of life and use of resources. An individual patient data meta-analysis of health economic data was conducted Twenty-five papers reporting 27 comparisons were found. Trials comparing proton pump inhibitors (PPI) with antacids (three trials) and histamine H2-receptor antagonists (H2RAs) (three trials), early endoscopy with initial acid suppression (five trials), H. pylori test and endoscope versus usual management (three trials), H. pylori test and treat versus endoscopy (six trials), and test and treat versus acid suppression alone in H. pylori positive patients (four trials), were pooled. PPIs were significantly more effective than both H2RAs and antacids. Relative risks (RR) and 95% confidence intervals (CI) were; for PPI compared with antacid 0.72 (95% CI 0.64 to 0.80), PPI compared with H2RA 0.63 (95% CI 0.47 to 0.85). Results for other drug comparisons were either absent or inconclusive. Initial endoscopy was associated with a small reduction in the risk of recurrent dyspeptic symptoms compared with H. pylori test and treat (OR 0.75, 95% CI 0.58 to 0.96), but was not cost effective (mean additional cost of endoscopy US$401 (95% CI $328 to 474

    2014-01-01

    Elite-standard rowers tend to use a fast-start strategy followed by an inverted parabolic-shaped speed profile in 2000-m races. This strategy is probably the best to manage energy resources during the race and maximise performance. This study investigated the use of virtual reality (VR) with novice rowers as a means to learn about energy management. Participants from an avatar group (n = 7) were instructed to track a virtual boat on a screen, whose speed was set individually to follow the appropriate to-be-learned speed profile. A control group (n = 8) followed an indoor training programme. In spite of similar physiological characteristics in the groups, the avatar group learned and maintained the required profile, resulting in an improved performance (i.e. a decrease in race duration), whereas the control group did not. These results suggest that VR is a means to learn an energy-related skill and improve performance.

    2017-10-01

    There is no question that regular exercise can be beneficial and lead to improvements in overall cardiovascular health. However, for patients with diabetes, exercise can also lead to challenges in maintaining blood glucose balance, particularly if patients are prescribed insulin or certain oral hypoglycemic agents. Hypoglycemia is the most common adverse event associated with exercise and insulin therapy, and the fear of hypoglycemia is also the greatest barrier to exercise for many patients. With the appropriate insulin dose adjustments and, in some cases, carbohydrate supplementation, blood glucose levels can be better managed during exercise and in recovery. In general, insulin strategies that help facilitate weight loss with regular exercise and recommendations around exercise adjustments to prevent hypoglycemia and hyperglycemia are often not discussed with patients because the recommendations can be complex and may differ from one individual to the next. This is a review of the current published literature on insulin dose adjustments and starting-point strategies for patients with diabetes in preparation for safe exercise.

    This study of competitiveness has three objectives. The first objective is to explain how macroeconomic and microeconomic factors can affect structural change in the US economy and how energy is linked to these factors. The second objective is to provide an explanation of how many individual decision makers, in responding to higher energy prices, have changed the structure of the economy. This structural change, and the effect it has had on energy use, is estimated for the US economy. A major component of these changes results from changes in US trade with other countries, which gives rise to the third objective. The third objective is to develop a research design that will allow a better understanding of the role that energy plays in the competitiveness of goods in world trade. 30 refs., 11 figs., 5 tabs.

  14. Strategy of image management in retail shops

    2007-12-01

    Full Text Available A sound positioning in consumers’ mind, along with strong promotion support, brought many retail shops to the top. This is mostly thanks to the image created in the consumers’ mind. A retail shop’s image may but need not conform to reality. Image often looks like a cliché. It overstates certain elements of the shop while simply omitting others. That is exactly why image is of great importance and often crucial to consumer behavior. This paper aims at determining the impact of image on customer behavior in the course of decision making about shopping and choosing a particular retail shop. Image is a significant factor of success of every company, hence also of a retail shops. It is a relatively strong value and a component of creating competitive advantage. But if we do not pay sufficient attention to image, it can become counterproductive. Instead to, like an additional value helps creating and maintaining the advantage in competition and realization of business aims, transforms into a limiting factor. Therefore, it is imperative to identify the elements of image that are of greatest importance to customers. Research has shown that customers choose the retail shop first and after that products and brands within this shop. When it comes to the supermarket, as a kind of retail shop, research has shown that two out of three shopping decisions are made by the customer on the spot, that is, without previous planning. That practically means that we can influence customers with different sales techniques. The paper suggests different strategies of image management for supermarkets and conventional shops. For supermarkets it is the “widest assortment” strategy, while for conventional shops the strategy is that of a “selected group of products“. Improvements to research methods will enable getting more information about customer behavior, while pressures of increased competition in the business environment will force retailers to get

    White, A.L.; Becker, M.B.; Schatzki, S.T.

    1990-02-01

    This study examines the energy implications of alternative solid waste management systems. As state and local governments move away from a traditional single facility strategies to more integrated waste management systems, energy use and recovery patterns will be substantially altered. The direct and indirect effects of such trends will result in major shifts in the volumes and composition of waste handled at incineration, recycling, composting and landfill facilities. In addition, second order energy savings will result from the substitution of recycled for virgin materials in the manufacturing sector. As such shifts occur, the energy balance -- the difference between energy recovered and energy used -- will undergo major adjustments. Such repercussions will occur at the regional, state, local and facility-specific level. Energy balances defined in this study cover seven use points, three recovery points and, separately, energy saved in production processes. For each of eleven Northeastern states, we estimate current balances based on existing waste management systems. State-specific profiles of recycling, composting, resource recovery and landfill activities provide the starting point for these base year estimates. Using the same estimating procedure, and taking into account each state's policy and planning objectives during the 1990's, we proceed to estimate the energy balances which will result if such objectives are met. By comparing current against future balances, we project the percentage change over a specified planning horizon. 2 figs., 37 tabs.

But its strong fluctuation and randomness have a serious effect on the stability of the microgrid without the coordination of the energy storage batteries. The main factors that influence the development of the energy storage system are the lack of valid operation and maintenance management as well as the cost control. By analyzing the typical characteristics of the energy storage batteries in their life cycle, the geometric process-based model including the deteriorating system and the improving system is firstly built for describing the operation process, the preventive maintenance process, and the corrective maintenance process. In addition, this paper proposes an optimized management strategy, which aims to minimize the long-run average cost of the energy storage batteries by defining the time interval of the detection and preventive maintenance process as well as the optimal corrective maintenance times, subjected to the state of health and the reliability conditions. The simulation is taken under the built model by applying the proposed energy storage batteries’ optimized management strategy, which verifies the effectiveness and applicability of the management strategy, denoting its obvious practicality on the current application.

    Full Text Available The article is devoted to the transformation of the energy strategy of Russia in the conditions of the current economic crisis. The special attention is paid to current trends in the sphere of international relations having a decisive influence on the formation of Russia’s energy strategy. The authors point to the crisis of the modern world, the deepening of interstate contradictions, the expansion of confrontation, the revision of the uniform principles of trade, established by the World Trade Organization, the changes in the global financial system. The authors investigate the possibility of political arrangements between the leading suppliers of oil on the destabilization of the oil market in order to achieve geopolitical goals. In the article special attention is also paid to the issue of political motivation of anti-Russian sanctions directed at impeding Russia’s development and its Fuel & Energy Complex, in particular. Today, against the background of the current political situation, the energy strategy of Russia is exposed to adjustment. The country has the important task of ensuring technological independence of the energy sector on the basis of import substitution of the equipment, diversification of the directions of export of energy resources, preservation of leading positions in the world market of peaceful nuclear energy, etc. The authors conclude that the energy strategy of Russia is important part of foreign policy strategy of the country, and it is focused on practical cooperation with all countries and is aimed at protecting interests of the state.

    Topology management via per-node transmission power adjustment has been shown effective in extending network lifetime. The existing algorithms constructs static topologies which fail to take the residual energy of network nodes, and cannot balance energy consumption efficiently. To address this problem, a Light Weighted Distributed Topology Control algorithm EMDCT(Energy Management Dynamic Control Topology ) is proposed in this paper. Based on the link metric of the network, both the energy consumption rate level and residual energy levels at the two end nodes are considered. EMDCT generates a Dynamic Topology that changes with the variation of node energy without the aid of location information, each node determines its transmission power according to local network information, which reduces the overhead complexity of EMDCT greatly. The experiment results show that EMDCT preserves network connectivity and manitains minimum-cost property of the network also it can extend network lifetime more remarkably.

  10. Energy Management of Smart Distribution Systems

    Science.gov (United States)

    Ansari, Bananeh

    Electric power distribution systems interface the end-users of electricity with the power grid. Traditional distribution systems are operated in a centralized fashion with the distribution system owner or operator being the only decision maker. The management and control architecture of distribution systems needs to gradually transform to accommodate the emerging smart grid technologies, distributed energy resources, and active electricity end-users or prosumers. The content of this document concerns with developing multi-task multi-objective energy management schemes for: 1) commercial/large residential prosumers, and 2) distribution system operator of a smart distribution system. The first part of this document describes a method of distributed energy management of multiple commercial/ large residential prosumers. These prosumers not only consume electricity, but also generate electricity using their roof-top solar photovoltaics systems. When photovoltaics generation is larger than local consumption, excess electricity will be fed into the distribution system, creating a voltage rise along the feeder. Distribution system operator cannot tolerate a significant voltage rise. ES can help the prosumers manage their electricity exchanges with the distribution system such that minimal voltage fluctuation occurs. The proposed distributed energy management scheme sizes and schedules each prosumer's ES to reduce the electricity bill and mitigate voltage rise along the feeder. The second part of this document focuses on emergency energy management and resilience assessment of a distribution system. The developed emergency energy management system uses available resources and redundancy to restore the distribution system's functionality fully or partially. The success of the restoration maneuver depends on how resilient the distribution system is. Engineering resilience terminology is used to evaluate the resilience of distribution system. The proposed emergency energy

    This final report presents the results of a study made on how facility management (FM) is positioned in enterprises and on how energy management can be integrated into the facility management process. Also, recommendations are made on the actions that are considered necessary to improve the understanding of facility management and energy management. The findings of an analysis made of the results of a survey among 200 enterprises, 20 interviews and 5 case studies are presented. The authors state that, in spite of the relatively small sample taken - mostly larger enterprises - trends in facility management and energy management could be shown. The findings of the survey, such as the relative importance of the integration of energy topics in facility management and the need for standardised indicators and benchmarking, are discussed in detail. Also, it is noted that the success of FM is in part due to delegation of responsibility to smaller business units or even to individual employees. The market potential for FM services is examined, with yearly growth rates of up to 20%. The importance of anchoring FM strategies at the top level of management is stressed, as is the need for promotion of the idea of facility management and training concepts for those responsible for its implementation.

  17. Evolutionary space station fluids management strategies

    1989-01-01

    Results are summarized for an 11-month study to define fluid storage and handling strategies and requirements for various specific mission case studies and their associated design impacts on the Space Station. There are a variety of fluid users which require a variety of fluids and use rates. Also, the cryogenic propellants required for NASA's STV, Planetary, and Code Z missions are enormous. The storage methods must accommodate fluids ranging from a high pressure gas or supercritical state fluid to a sub-cooled liquid (and superfluid helium). These requirements begin in the year 1994, reach a maximum of nearly 1800 metric tons in the year 2004, and trail off to the year 2018, as currently planned. It is conceivable that the cryogenic propellant needs for the STV and/or Lunar mission models will be met by LTCSF LH2/LO2 tanksets attached to the SS truss structure. Concepts and corresponding transfer and delivery operations have been presented for STV propellant provisioning from the SS. A growth orbit maneuvering vehicle (OMV) and associated servicing capability will be required to move tanksets from delivery launch vehicles to the SS or co-orbiting platforms. Also, appropriate changes to the software used for OMV operation are necessary to allow for the combined operation of the growth OMV. To support fluid management activities at the Space Station for the experimental payloads and propellant provisioning, there must be truss structure space allocated for fluid carriers and propellant tanksets, and substantial beam strengthening may be required. The Station must have two Mobile Remote Manipulator Systems (MRMS) and the growth OMV propellant handling operations for the STV at the SS. Propellant needs for the Planetary Initiatives and Code Z mission models will most likely be provided by co-orbiting propellant platform(s). Space Station impacts for Code Z mission fluid management activities will be minimal.

    materials strategy, based upon additional events and information, by the end of 2011.DOE's strategy with respect to critical materials rests on three pillars. First, diversified global supply chains are essential. To manage supply risk, multiple sources of materials are required. This means taking steps to facilitate extraction, processing and manufacturing here in the United States, as well as encouraging other nations to expedite alternative supplies. In all cases, extraction and processing should be done in an environmentally sound manner. Second, substitutes must be developed. Research leading to material and technology substitutes will improve flexibility and help meet the material needs of the clean energy economy. Third, recycling, reuse and more efficient use could significantly lower world demand for newly extracted materials. Research into recycling processes coupled with well-designed policies will help make recycling economically viable over time.The scope of this report is limited. It does not address the material needs of the entire economy, the entire energy sector or even all clean energy technologies. Time and resource limitations precluded a comprehensive scope. Among the topics that merit additional research are the use of rare earth metals in catalytic converters and in petroleum refining. These topics are discussed briefly in Chapter 2.

    Energy consumption in downlink mode is becoming an important topic as cellular communications grow into a large scale enterprise. The search for high rates keeping energy constraints low has put forward the idea that cells with smaller size may improve not only the capacity of the network, but also reduce the amount of energy that is needed to achieve such capacities. When using heterogeneous networks, users can be encouraged to handoff to a femtocell, that offers better capacity per unit energy spent, by means of different handoff strategies. These strategies may also improve the energy use of the network if the handoff priority is given to both, capacity, and energy use. © 2012 IEEE.

    Full Text Available This paper examines energy management in a heterogeneous processor consisting of an integrated CPU–GPU for high-performance computing (HPC applications. Energy management for HPC applications is challenged by their uncompromising performance requirements and complicated by the need for coordinating energy management across distinct core types – a new and less understood problem. We examine the intra-node CPU–GPU frequency sensitivity of HPC applications on tightly coupled CPU–GPU architectures as the first step in understanding power and performance optimization for a heterogeneous multi-node HPC system. The insights from this analysis form the basis of a coordinated energy management scheme, called DynaCo, for integrated CPU–GPU architectures. We implement DynaCo on a modern heterogeneous processor and compare its performance to a state-of-the-art power- and performance-management algorithm. DynaCo improves measured average energy-delay squared (ED2 product by up to 30% with less than 2% average performance loss across several exascale and other HPC workloads.

  13. Optimal urban water conservation strategies considering embedded energy: coupling end-use and utility water-energy models.

    2014-12-01

    Although most freshwater resources are used in agriculture, a greater amount of energy is consumed per unit of water supply for urban areas. Therefore, efforts to reduce the carbon footprint of water in cities, including the energy embedded within household uses, can be an order of magnitude larger than for other water uses. This characteristic of urban water systems creates a promising opportunity to reduce global greenhouse gas emissions, particularly given rapidly growing urbanization worldwide. Based on a previous Water-Energy-CO2 emissions model for household water end uses, this research introduces a probabilistic two-stage optimization model considering technical and behavioral decision variables to obtain the most economical strategies to minimize household water and water-related energy bills given both water and energy price shocks. Results show that adoption rates to reduce energy intensive appliances increase significantly, resulting in an overall 20% growth in indoor water conservation if household dwellers include the energy cost of their water use. To analyze the consequences on a utility-scale, we develop an hourly water-energy model based on data from East Bay Municipal Utility District in California, including the residential consumption, obtaining that water end uses accounts for roughly 90% of total water-related energy, but the 10% that is managed by the utility is worth over 12 million annually. Once the entire end-use + utility model is completed, several demand-side management conservation strategies were simulated for the city of San Ramon. In this smaller water district, roughly 5% of total EBMUD water use, we found that the optimal household strategies can reduce total GHG emissions by 4% and utility's energy cost over 70,000/yr. Especially interesting from the utility perspective could be the "smoothing" of water use peaks by avoiding daytime irrigation that among other benefits might reduce utility energy costs by 0.5% according to our

  14. Strategies for sustainable management of renewable resources during environmental change.

    2017-03-15

    As a consequence of global environmental change, management strategies that can deal with unexpected change in resource dynamics are becoming increasingly important. In this paper we undertake a novel approach to studying resource growth problems using a computational form of adaptive management to find optimal strategies for prevalent natural resource management dilemmas. We scrutinize adaptive management, or learning-by-doing, to better understand how to simultaneously manage and learn about a system when its dynamics are unknown. We study important trade-offs in decision-making with respect to choosing optimal actions (harvest efforts) for sustainable management during change. This is operationalized through an artificially intelligent model where we analyze how different trends and fluctuations in growth rates of a renewable resource affect the performance of different management strategies. Our results show that the optimal strategy for managing resources with declining growth is capable of managing resources with fluctuating or increasing growth at a negligible cost, creating in a management strategy that is both efficient and robust towards future unknown changes. To obtain this strategy, adaptive management should strive for: high learning rates to new knowledge, high valuation of future outcomes and modest exploration around what is perceived as the optimal action. © 2017 The Author(s).

    Hurd, G.L. [Anadarko Canada Corp., Calgary, AB (Canada)

    2003-07-01

    This presentation offered some perspectives in security risk management as it relates to the energy sector. Since the events of September 11, 2001 much attention has been given to terrorism and the business is reviewing protection strategies. The paper made reference to each of the following vulnerabilities in the energy sector: information technology, globalization, business restructuring, interdependencies, political/regulatory change, and physical/human factors. The vulnerability of information technology is that it can be subject to cyber and virus attacks. Dangers of globalization lie in privacy and information security, forced nationalization, organized crime, and anti-globalization efforts. It was noted that the Y2K phenomenon provided valuable lessons regarding interdependencies and the effects of power outages, water availability, transportation disruption, common utility corridor accidents, and compounding incidents. The paper also noted the conflict between the government's desire to have a resilient infrastructure that can withstand and recover from attacks versus a company's ability to afford this capability. The physical/human factors that need to be considered in risk management include crime, domestic terrorism, and disasters such as natural disasters, industrial disasters and crisis. The energy industry has geographically dispersed vulnerable systems. It has done a fair job of physical security and has good emergency management practices, but it was noted that the industry cannot protect against all threats. A strategy of vigilance and awareness is needed to deal with threats. Other strategies include contingency planning, physical security, employee communication, and emergency response plans. tabs., figs.

    The main EU programmes, supporting the renewable deployment, are the research and development programmes JOULE, THERMIE and FAIR, included in the 4th framework programme, the ALTENER programme and the `Community Support Framework` programme. Research and development (R and E) activity within the JOULE and THERMIE programmes are divided into five areas, of which the third concerns the renewable energies. The support could range from 40 to 100 % of the cost. JOULE programme is research oriented, while the THERMIE programme is demonstration oriented. The FAIR programme is also a specific research and development programme for agriculture and agrifood industry. It could cover, among others, projects in connection with the biogas exploitation. The ALTENER programme provides support for the so called `software` actions, promoting renewables, mainly training and information actions, including events like the present one. Furthermode, it provides support for technical specifications, creation of infrastructure for the promotion of renewables and so on. ALTENER does not support investments. Finally the `Community Support Framework` programme promoting the regional development, could, in some cases, support traditional technology investments in relation to renewables. (au)

    Building Energy Performance Standards (BEPS) were mandated by the Energy Conservation Standards for New Buildings Act of 1976 (Title III of Energy Conservation and Production Act) to promote energy efficiency and the use of renewable resources in new buildings. The report analyzes alternative Federal strategies and their component policy instruments and recommends a strategy for achieving the goals of the Act. The concern is limited to space conditioning (heating, cooling, and lighting) and water heating. The policy instruments considered include greater reliance on market forces; research and development; information, education and demonstration programs; tax incentives and sanctions; mortgage and finance programs; and regulations and standards. The analysis starts with an explanation of the barriers to energy conservation in the residential and commercial sectors. Individual policy instruments are then described and evaluated with respect to energy conservation, economic efficiency, equity, political impacts, and implementation and other transitional impacts. Five possible strategies are identified: (1) increased reliance on the market place; (2) energy consumption tax and supply subsidies; (3) BEPS with no sanctions and no incentives; (4) BEPS with sanctions and incentives (price control); and (5) BEPS with sanctions and incentives (no price controls). A comparative analysis is performed. Elements are proposed for inclusion in a comprehensive strategy for conservation in new buildings. (MCW)

    2002-06-01

    In this paper, the author reviewed the energy management activities, over the last two years, of Petroleos Mexicanos, also known as Pemex. These activities generated substantial savings. A brief overview of Pemex was provided. The State Oil Company of Mexico, Pemex occupies the third rank of the world oil producers, and is in seventh place in terms of proven reserves. The gas production has earned the company the ninth spot, and it is in tenth place as far as its refining capacity is concerned. Pemex has annual revenues of 50, 000 million American dollars and operates in excess of 1,000 facilities. The energy management program implemented covered an experts network, training, campaigns, and information and monitoring system. Each of the components of the energy management system were reviewed. Linking each facility, the experts network was created to enhance the efficient use of energy. The Energy Saving and Environmental Protection campaign was held over the period 1999-2000 and involved the participation of 209 work sites. For its part, the Energy Efficient Use and Savings campaign took place in 2000-2001, involving 205 work sites. Both resulted in substantial savings. An internal carbon dioxide trading system was also implemented to improve air quality, and was designed to provide a cap and trade carbon dioxide emissions. The next phase involved the implementation of an information and monitoring system, which defined an Energy Consumption Index used in monthly reports. The next steps in the process were briefly outlined. 5 figs.

    The power industry restructuring in various countries in recent years has created an environment where trading of electric energy is conducted in a market environment. In such an environment, electric power companies compete for the market share through spot and bilateral markets. Being profit driven, electric power companies need to make decisions on spot market bidding, contract evaluation, and risk management. New methods and software tools are required to meet these upcoming needs. In this research, bidding strategy and contract pricing are studied from a market participant's viewpoint; new methods are developed to guide a market participant in spot and bilateral market operation. A supplier's spot market bidding decision is studied. Stochastic optimization is formulated to calculate a supplier's optimal bids in a single time period. This decision making problem is also formulated as a Markov Decision Process. All the competitors are represented by their bidding parameters with corresponding probabilities. A systematic method is developed to calculate transition probabilities and rewards. The optimal strategy is calculated to maximize the expected reward over a planning horizon. Besides the spot market, a power producer can also trade in the bilateral markets. Bidding strategies in a bilateral market are studied with game theory techniques. Necessary and sufficient conditions of Nash Equilibrium (NE) bidding strategy are derived based on the generators' cost and the loads' willingness to pay. The study shows that in any NE, market efficiency is achieved. Furthermore, all Nash equilibria are revenue equivalent for the generators. The pricing of "Flexible" contracts, which allow delivery flexibility over a period of time with a fixed total amount of electricity to be delivered, is analyzed based on the no-arbitrage pricing principle. The proposed algorithm calculates the price based on the optimality condition of the stochastic optimization formulation

  6. Optimal Bidding Strategy for Renewable Microgrid with Active Network Management

    2016-01-01

    Full Text Available Active Network Management (ANM enables a microgrid to optimally dispatch the active/reactive power of its Renewable Distributed Generation (RDG and Battery Energy Storage System (BESS units in real time. Thus, a microgrid with high penetration of RDGs can handle their uncertainties and variabilities to achieve the stable operation using ANM. However, the actual power flow in the line connecting the main grid and microgrid may deviate significantly from the day-ahead bids if the bids are determined without consideration of the real-time adjustment through ANM, which will lead to a substantial imbalance cost. Therefore, this study proposes a formulation for obtaining an optimal bidding which reflects the change of power flow in the connecting line by real-time adjustment using ANM. The proposed formulation maximizes the expected profit of the microgrid considering various network and physical constraints. The effectiveness of the proposed bidding strategy is verified through the simulations with a 33-bus test microgrid. The simulation results show that the proposed bidding strategy improves the expected operating profit by reducing the imbalance cost to a greater degree compared to the basic bidding strategy without consideration of ANM.

  7. Energy Smart Management of Scientific Data

    Scientific data centers comprised of high-powered computing equipment and large capacity disk storage systems consume considerable amount of energy. Dynamic power management techniques (DPM) are commonly used for saving energy in disk systems. These involve powering down disks that exhibit long idle periods and placing them in standby mode. A file request from a disk in standby mode will incur both energy and performance penalties as it takes energy (and time) to spin up the disk before it can serve a file. For this reason, DPM has to make decisions as to when to transition the disk into standby mode such that the energy saved is greater than the energy needed to spin it up again and the performance penalty is tolerable. The length of the idle period until the DPM decides to power down a disk is called idlenessthreshold. In this paper, we study both analytically and experimentally dynamic power management techniques that save energy subject to performance constraints on file access costs. Based on observed workloads of scientific applications and disk characteristics, we provide a methodology for determining file assignment to disks and computing idleness thresholds that result in significant improvements to the energy saved by existing DPMsolutions while meeting response time constraints. We validate our methods with simulations that use traces taken from scientific applications.

  8. Smart EV Energy Management System to Support Grid Services

    Science.gov (United States)

    Wang, Bin

    Under smart grid scenarios, the advanced sensing and metering technologies have been applied to the legacy power grid to improve the system observability and the real-time situational awareness. Meanwhile, there is increasing amount of distributed energy resources (DERs), such as renewable generations, electric vehicles (EVs) and battery energy storage system (BESS), etc., being integrated into the power system. However, the integration of EVs, which can be modeled as controllable mobile energy devices, brings both challenges and opportunities to the grid planning and energy management, due to the intermittency of renewable generation, uncertainties of EV driver behaviors, etc. This dissertation aims to solve the real-time EV energy management problem in order to improve the overall grid efficiency, reliability and economics, using online and predictive optimization strategies. Most of the previous research on EV energy management strategies and algorithms are based on simplified models with unrealistic assumptions that the EV charging behaviors are perfectly known or following known distributions, such as the arriving time, leaving time and energy consumption values, etc. These approaches fail to obtain the optimal solutions in real-time because of the system uncertainties. Moreover, there is lack of data-driven strategy that performs online and predictive scheduling for EV charging behaviors under microgrid scenarios. Therefore, we develop an online predictive EV scheduling framework, considering uncertainties of renewable generation, building load and EV driver behaviors, etc., based on real-world data. A kernel-based estimator is developed to predict the charging session parameters in real-time with improved estimation accuracy. The efficacy of various optimization strategies that are supported by this framework, including valley-filling, cost reduction, event-based control, etc., has been demonstrated. In addition, the existing simulation-based approaches do

    2017-09-01

    Full Text Available The regional level is essential for the use of renewable energies since on this level national political goals are harmonized with implementation activities. Hence, regional strategies can, we argue, be useful. Yet, these strategies must be tailored to meet a variety of contextual conditions. Within this study, we identified natural and socio-economic conditions that need to be considered when developing regional strategies for Energiewende. Focusing on these conditions, we conducted a multivariate statistical analysis of all 412 German districts (Landkreise. We identified nine energy context types characterized by different renewable energy potentials and socio-economic conditions. We propose to develop one generic regional energy transition strategy for each of the energy context types. These can serve as a governance tool that operationalizes and allocates national Energiewende goals according to regional contextual conditions. Moreover, the energy context types may support regional decision makers by allowing them to prioritize steps in the transition process, to establish networks with, and to learn from, similar regions.

  18. Strategies for commercializing customer thermal-energy storage. [64 references

    1976-12-01

    This report presents strategies for commercializing customer thermal storage. Four storage techniques are evaluated: space heating, air conditioning, hot-water heating, and interruptible hot-water heating. The storage systems involved store off-peak electric energy for thermal applications during peak load hours. Analyses of both storage techniques and principal parties affected by storage indicate four barriers: the absence of (1) commercially available air conditioning storage devices, (2) appropriate rates, (3) information on both rates and devices, and (4) widespread utility support. Development of appropriate rates is the key to commercialization. The criteria used to evaluate rate types are: maximum combined utility and customer benefits, ease of commercialization, and practical feasibility. Four rate types--demand charges, time-of-use rates, and two forms of load management rates (a monthly credit and an off-peak discount)--plus the possibility of utility ownership are considered. The best rate types for each storage option are: for hot-water heating, a monthly credit for allowing utility interruptions or an off-peak price discount for storage; for space heating, an off-peak discount contingent upon meeting utility requirements; and for air conditioning, an off-peak discount plus monthly credit.

    To examine strategies employed by clinicians from different disciplines to manage their emotions during difficult healthcare conversations. Self-report questionnaires were collected prior to simulation-based Program to Enhance Relational and Communication Skills (PERCS) workshops for professionals representing a range of experience and specialties at a tertiary pediatric hospital. In response to an open-ended prompt, clinicians qualitatively described their own strategies for managing their emotions during difficult healthcare conversations. 126 respondents reported emotion management strategies. Respondents included physicians (42%), nurses (29%), medical interpreters (16%), psychosocial professionals (9%), and other (4%). Respondents identified 1-4 strategies. Five strategy categories were identified: Self-Care (51%), Preparatory and Relational Skills, (29%), Empathic Presence (28%), Team Approach (26%), and Professional Identity (20%). Across disciplines and experience levels, clinicians have developed strategies to manage their emotions when holding difficult healthcare conversations. These strategies support clinicians before, during and after difficult conversations. Understanding what strategies clinicians already employ to manage their emotions when holding difficult conversations has implications for educational planning and implementation. This study has potential to inform the development of education to support clinicians' awareness of their emotions and to enhance the range and effectiveness of emotion management during difficult healthcare conversations.

    Energy load models in the process of hydrogen reduction of ilmenite for lunar oxygen production are being developed. The load models will be used as a first step to ultimately determine the optimal energy system needed to supply the power requirements for the process. The goal is to determine the energy requirements in the process of hydrogen reduction of ilmenite to produce oxygen. The general approach is shown, and the objectives are to determine the energy loads of the processes in the system. Subsequent energy management studies will be made to minimize the system losses (irreversibilities) and to design optimal energy system power requirements. A number of processes are being proposed as possible candidates for lunar application and some detailed experimental efforts are being conducted within this project at the University of Arizona. Priorities are directed toward developing the energy models for each of the proposed processes being considered. The immediate goals are to identify the variables that would impact energy requirements and energy sources of supply.

    The policy instruments considered include: greater reliance on market forces; research and development; information, education and demonstration programs; tax incentives and sanctions; mortgage and finance programs; and regulations and standards. The analysis starts with an explanation of the barriers to energy conservation in the residential and commercial sectors. Individual policy instruments are described and evaluated with respect to energy conservation, economic efficiency, equity, political impacts, and implementation and other transitional impacts. Five possible strategies are identified: (1) increased reliance on the market place; (2) energy consumption tax and supply subsidies; (3) Building Energy Performance Standards (BEPS) with no sanctions and no incentives; (4) BEPS with sanctions and incentives (price control); and (5) BEPS with sanctions and incentives (no price controls). A comparative analysis is performed. Elements are proposed for inclusion in a comprehensive strategy for conservation in new buildings.

  14. CHANGE MANAGEMENT STRATEGIES RELATED TO THE GLOBAL ENVIRONMENT COMPLEXITY

    Directory of Open Access Journals (Sweden)

    Elena DOVAL

    2016-12-01

    Full Text Available The changes in organizations appear as a reaction to the organizational environment changes. In order to manage these changes successfully, the managers need to anticipate and design alternative strategies by preparing different options.  Nevertheless, the complexity of the global environment forces the managers to adopt strategies for their organizations that are facilitating the creation of new strategic competences and competitive advantages to face the environmental rapid changes. In this context, this paper is aiming to illustrate the main directions the change management may consider to change the organization strategies in order to harmonize them to the external environment, such as: integration versus externalization, flexible specialization and flexible organization, standardization versus adaptation, market segmentation, relationship building and maintaining and communication integration.  However, the new strategies are based on a changed attitude of the managers towards the competitive advantage that is dynamic and focused on creation rather then to operations.

    Bugni, Estelle; Cohen, Richard; Mazellier, Cécile

    2017-12-01

    Medical biology laboratories rely especially on internal quality control (IQC) to monitor the performance of equipment and ensure results reliability. Strategies for these controls vary considerably from one laboratory to another. Some laboratories use Westgard's rules to detect drifts and are faced with a large number of false rejections caused by frequent runs of control samples and strategies that activate all rejection rules, regardless of the analyte considered. To minimize these rejections, some laboratories have combined several theories, sometimes despite the relevance of the resulting strategy. In this article, we want to explain the foundations of the main IQC theories and set out a strategy to optimize the detection of problems while minimizing false IQC rejections. We will also address some frequently asked questions from laboratories as part of ISO 15189 accreditation.

    : Previous studies have provided theoretical and empirical evidence that environmental forces influence hospital strategy. : Rooted in resource dependence theory and the information uncertainty perspective, this study examined the relationship between environmental market characteristics and hospitals' selection of a health information technology (HIT) management strategy. : A cross-sectional design is used to analyze secondary data from the American Hospital Association Annual Survey, the Healthcare Information and Management Systems Society Analytics Database, and the Area Resource File. Univariate and multinomial logistic regression analyses are used. : Overall, 3,221 hospitals were studied, of which 60.9% pursed a single-vendor HIT management strategy, 28.9% pursued a best-of-suite strategy, and 10.2% used a best-of-breed strategy. Multivariate analyses controlling for hospital characteristics found that measures of environmental factors representing munificence, dynamism, and/or complexity were systematically associated with various hospital HIT management strategy use. Specifically, the number of generalist physicians per capita was positively associated with the single-vendor strategy (B = -5.64, p = .10). Hospitals in urban markets were more likely to pursue the best-of-suite strategy (B = 0.622, p < .001). Dynamism, measured as the number of managed care contracts for a given hospital, was negatively associated with the single-vendor strategy (B = 0.004, p = .049). Lastly, complexity, measured as market competition, was positively associated with the best-of-breed strategy (B = 0.623, p = .042). : By and large, environmental factors are associated with hospital HIT management strategies in mostly theoretically supported ways. Hospital leaders and policy makers interested in influencing the adoption of hospital HIT should consider how market conditions influence HIT management decisions as part of programs to promote meaningful use.

    2009-04-15

    Today, Denmark has some of the most strict energy requirements in the world for new buildings. The long-term vision is that all new buildings shall be plus-energy buildings, i.e. they generate more energy than they consume. At the same time, the energy consumption in the existing buildings shall be reduced significantly. The strategy presents initiatives that shall contribute to reduce the energy consumption in both new buildings and in the existing buildings. The initiatives are eg. still stricter energy requirements for new buildings, stricter building codes for the existing buildings, economic incentives, better education, improvements of accounting of the energy consumption, and innovation. All the initiatives must secure that any reduction in energy consumption does not affect the indoor climate negatively. (ln)

    According to this publication, Norway is now about to consume more energy than the country produces and the authorities realize that there is a need for increased energy flexibility in buildings. Traditionally, energy flexibility in buildings is defined as the possibility of using several energy sources for heating. The net total floor area in Norwegian buildings is 313 million m{sup 2}. Dwellings account for 65%, commercial buildings for 35%. Private dwellings in small houses account for 57%. Conditions are such that improvement in the energy consumption can be achieved faster by measures aiming at existing buildings rather than at new buildings. House owners and energy suppliers maintain that the prices of electricity and oil are a barrier for the introduction of new renewable energy sources. The superior strategy is that all measures suggested should contribute to the authorities` target of a sustainable development, in the climate policy and the energy supply policy. 9 refs., 12 figs., 4 tabs.

  20. Photovoltaic Energy Harvester with Power Management System

    Directory of Open Access Journals (Sweden)

    M. Ferri

    2010-01-01

    Full Text Available We present a photovoltaic energy harvester, realized in 0.35-μm CMOS technology. The proposed system collects light energy from the environment, by means of 2-mm2 on-chip integrated microsolar cells, and accumulates it in an external capacitor. While the capacitor is charging, the load is disconnected. When the energy in the external capacitor is enough to operate the load for a predefined time slot, the load is connected to the capacitor by a power management circuit. The choice of the value of the capacitance determines the operating time slot for the load. The proposed solution is suitable for discrete-time-regime applications, such as sensor network nodes, or, in general, systems that require power supply periodically for short time slots. The power management circuit includes a charge pump, a comparator, a level shifter, and a linear voltage regulator. The whole system has been extensively simulated, integrated, and experimentally characterized.

    Escriva-Bou, Alvar; Lund, Jay R.; Pulido-Velazquez, Manuel

    2015-06-01

    Although most freshwater resources are used in agriculture, residential water use is a much more energy intensive user. Based on this, we analyze the increased willingness to adopt water conservation strategies if energy cost is included in the customers' utility function. Using a Water-Energy-CO2 emissions model for household water end uses and probability distribution functions for parameters affecting water and water-related energy use in 10 different locations in California, this research introduces a probabilistic two-stage optimization model considering technical and behavioral decision variables to obtain the most economical strategies to minimize household water and water-related energy bills and costs given both water and energy price shocks. Results can provide an upper bound of household savings for customers with well-behaved preferences, and show greater adoption rates to reduce energy intensive appliances when energy is accounted, resulting in an overall 24% reduction in indoor water use that represents a 30% reduction in water-related energy use and a 53% reduction in household water-related CO2 emissions. Previous use patterns and water and energy rate structures can affect greatly the potential benefits for customers and so their behavior. Given that water and energy are somewhat complementary goods for customers, we use results of the optimization to obtain own-price and cross-price elasticities of residential water use by simulating increases in water and energy prices. While the results are highly influenced by assumptions due to lack of empirical data, the method presented has no precedent in the literature and hopefully will stimulate the collection of additional relevant data.

    To illustrate the need for and suggest strategies that will enhance sustainable management of a large intensive care unit (ICU). The challenges faced by intensive care nursing in South Africa are well documented. However, there appear to be no strategies available to assist nurses to manage large ICUs or for ICU managers to deal with problems as they arise. Data sources to illustrate the need for strategies were challenges described by ICU managers in the management of large ICUs. A purposive sample of managers was included in individual interviews during compilation of evidence regarding the challenges experienced in the management of large ICUs. The challenges were presented at the Critical Care Society of Southern Africa Congress held on 28 August to 2 September 2012 in Sun City North-West province, South Africa. Five strategies are suggested for the challenges identified: divide the units into sections; develop a highly skilled and effective nursing workforce to ensure delivery of quality nursing care; create a culture to retain an effective ICU nursing team; manage assets; and determine the needs of ICU nurses. ICUs need measures to drive the desired strategies into actions to continuously improve the management of the unit. Future research should be aimed at investigating the effectiveness of the strategies identified. This research highlights issues relating to large ICUs and the strategies will assist ICU managers to deal with problems related to large unit sizes, shortage of trained ICU nurses, use of agency nurses, shortage of equipment and supplies and stressors in the ICU. The article will make a contribution to the body of nursing literature on management of ICUs. © 2014 John Wiley & Sons Ltd.

    In today's volatile healthcare environment, traditional planning tools are inadequate to guide financial managers of provider organizations in developing managed care strategies. These tools often disregard the uncertainty surrounding market forces such as employee benefit structure, the future of Medicare managed care, and the impact of consumer behavior. Scenario analysis overcomes this limitation by acknowledging the uncertain healthcare environment and articulating a set of plausible alternative futures, thus supplying financial executives with the perspective to craft strategies that can improve the market position of their organizations. By being alert for trigger points that might signal the rise of a specific scenario, financial managers can increase their preparedness for changes in market forces.

    There are many opportunities for industrial and commercial facilities to improve energy efficiency by minimizing waste through process optimization. Large energy users can effectively reduce energy costs, improve profits and reduce greenhouse gas emissions by using computing and control equipment. This book covers all aspects of an Energy Management Information System (EMIS) including metering, data collection, data analysis, reporting and cost benefit analyses. EMIS provides relevant information to businesses that enables them to improve energy performance. EMIS deliverables include early detection of poor performance, support for decision making and effective energy reporting. EMIS also features data storage, calculation of effective targets for energy use and comparative energy consumption. Computer systems can be used to improve business performance in terms of finance, personnel, sales, resource planning, maintenance, process control, design and training. In the 1980s, the Canadian Industry Program for Energy Conservation (CIPEC) developed 2 versions of an energy accounting manual to help industrial, commercial and institutional sectors implement energy-accounting systems. The manual was revised in 1989 and is a useful energy management tool for business and other organizations. The EMIS examples described in this booklet reflect that energy is a variable operating cost, not a fixed overhead charge. 8 tabs., 38 figs.

    Full Text Available ABSTRACT Caregiving has an important influence on the prognosis of dementia, particularly regarding the management strategy implemented. Therefore, evaluating which characteristics of caregivers can influence the choice of a particular strategy for managing dementia is needed. Objective: To evaluate the association between characteristics of caregivers and their management strategies as applied to patients with dementia. Methods: A cross-sectional study involving 45 professional caregivers from two nursing homes in Porto Alegre, Brazil, was conducted. Age, gender, education, years as a caregiver, income, burden, depressive and anxiety symptoms and dementia management strategies were evaluated for all participants. Pearson's or Spearman's correlation tests were applied according to the variable distribution (parametric or non-parametric. Bivariate correlation analysis was applied. P<0.05 was considered statistically significant. Results: There was a significant and moderate positive correlation between burden measured by the Zarit Burden Interview and criticism measured by the Dementia Management Strategies Scale (Spearman's rho = 0.555, p < 0.001. No other correlations were observed. Conclusion: Among the caregiver characteristics that directly affect the approach to managing dementia, high caregiver burden was found to be associated with high criticism, an authoritative way of managing dementia. This exploratory study indicated that a possible way of decreasing negative dementia management is to reduce caregiver burden.

  13. The Development of Cloud Energy Management

    2015-05-01

    Full Text Available The energy management service (EMS has been utilized for saving energy since 1982 by managing the energy usage of site or facilities through the microprocessor, computer, Ethernet, internet, and wireless sensor network. The development and represented function groups of EMS are illustrated in the supplementary file of this paper. Along with this tendency, a cloud EMS, named the intelligent energy management network (iEN, was launched by Chunghwa Telecom in 2011 and tested during a pilot run from 2012 to 2013. The cloud EMS integrated three service modes together, including infrastructure as a service (IaaS, platform as a service (PaaS, and software as a service (SaaS. This cloud EMS could reduce the facility cost and enable a continuously improved service for energy conservation. From the literature review, 32 selected EMS cases of whole site and single facility were chosen for calculating the energy savings and payback rate. According to the literature, the average energy savings by applying EMS are 11.6% and 21.4% for the whole site and single facility, respectively. The iEN was applied on 55 demo sites with the similar scale, the same kind of machines and approaching conditions. The testing sites include a factory, a complex building, and a residual building, 12 lighting systems and 8 air conditioning systems. According to the testing results, the average energy savings by applying iEN are 10% and 23.5% for the whole site and single facility, respectively. Comparing with the reported EMS cases, it was found that the energy savings by adopting the cloud EMS were only 70%–80% compared with those using the traditional EMS. Although the cloud EMS presented less energy savings, it revolutionized the traditional EMS by its innovative business model. Compared with the averaged 1.7 years payback period of the traditional EMS, more than 70% of the cloud EMS cases could pay back immediately for the service fees and without the equipment investment.

  14. Integrated Management of Residential Energy Resources

    Antunes C. H.

    2012-10-01

    Full Text Available The increasing deployment of distributed generation systems based on renewables in the residential sector, the development of information and communication technologies and the expected evolution of traditional power systems towards smart grids are inducing changes in the passive role of end-users, namely with stimuli to change residential demand patterns. The residential user should be able to make decisions and efficiently manage his energy resources by taking advantages from his flexibility in load usage with the aim to minimize the electricity bill without depreciating the quality of energy services provided. The aim of this paper is characterizing electricity consumption in the residential sector and categorizing the different loads according to their typical usage, working cycles, technical constraints and possible degree of control. This categorization of end-use loads contributes to ascertain the availability of controllable loads to be managed as well as the different direct management actions that can be implemented. The ability to implement different management actions over diverse end-use load will increase the responsiveness of demand and potentially raises the willingness of end-users to accept such activities. The impacts on the aggregated national demand of large-scale dissemination of management systems that would help the end-user to make decisions regarding electricity consumption are predicted using a simulator that generates the aggregated residential sector electricity consumption under variable prices.

    2015-05-01

    Integrated environmental management became an economic necessity after industrial development proved to be unsustainable without consideration of environmental direct and indirect impacts. Energy dependency and air pollution along with climate change grew into major challenges facing developed and developing countries alike. Thus, a new global market structure emerged and changed the way we do trade. The search intensified for alternatives to petroleum. However, scientists, policy makers, and environmental activists agreed to focus on strategic conservation and optimization of energy use. Environmental concerns will remain partially unaddressed with the current pace of consumption because greenhouse gas emissions will continue to rise with economic growth. This paper discusses energy efficiency, steady integration of alternative sources, and increased use of best available technologies. Energy criteria developed for environmental labeling certification are presented. Our intention is to encourage manufacturers and service providers to supply consumers with less polluting and energy-consuming goods and services, inform consumers of the environmental and energy impacts, and thereby instill sustainable and responsible consumption. As several programs were initiated in developed countries, environmental labeling requirements created barriers to many exports manufactured in developing countries, affecting current world trade and putting more pressure on countries to meet those requirements. Defining an institutional and legal framework of environmental labeling is a key challenge in implementing such programs for critical economic sectors like tourism, textiles, and food production where energy needs are the most important aspect to control. A case study of Tunisia and its experience with eco-labeling is presented.

Based on current population and consumption trends, the Nation's use of energy and minerals can be expected to grow, driving the demand for ever broader scientific understanding of resource formation, location, and availability. In addition, the increasing importance of environmental stewardship, human health, and sustainable growth place further emphasis on energy and mineral resources research and understanding. Collectively, these trends in resource demand and the interconnectedness among resources will lead to new challenges and, in turn, require cutting-edge science for the next generation of societal decisions. The contributions of the U.S. Geological Survey to energy and minerals research are well established. Based on five interrelated goals, this plan establishes a comprehensive science strategy. It provides a structure that identifies the most critical aspects of energy and mineral resources for the coming decade. * Goal 1. - Understand fundamental Earth processes that form energy and mineral resources. * Goal 2. - Understand the environmental behavior of energy and mineral resources and their waste products. * Goal 3. - Provide inventories and assessments of energy and mineral resources. * Goal 4. - Understand the effects of energy and mineral development on natural resources. * Goal 5. - Understand the availability and reliability of energy and mineral resource supplies. Within each goal, multiple, scalable actions are identified. The level of specificity and complexity of these actions varies, consistent with the reality that even a modest refocus can yield large payoffs in the near term whereas more ambitious plans may take years to reach fruition. As such, prioritization of actions is largely dependent on policy direction, available resources, and the sequencing of prerequisite steps that will

    This paper aims to understand the relationship between households’ livelihood strategy and soil management using commonalities among rural households. We grouped households into four distinct types according to similar livelihood diversification strategies. For each household type, we identified...... the dominant income-generating strategies as well as the main agronomic activities pursued. The household types were: (I) households that pursue a cereal-based livelihood diversification strategy (23 %); (II) households predominantly engaged in casual off-farm-based strategy (15 %); (III) households......(Type IV) were not only economically “better off” but also more likely to undertake improved soil management practices than those pursuing less economically rewarding, cereal-based (Type I) or casual off-farm-based (Type II) livelihood diversification strategies. This was largely attributed to differences...

    Full Text Available Mycosis fungoides is the most common primary cutaneous T-cell lymphoma. The approach to diagnosis and further follow-up is outlined. Evidence for interventions is based classically on a Tumor Node Metastasis Blood TNMB “stage-based” approach. The treatment options in India are limited. The options as per risk stratification and prognostic index are discussed. Early stages and low-risk patients can be managed with expectant policy or skin-directed therapies including topical steroids and phototherapy; intermediate-risk patients can be opted for interferons or retinoids or low dose methotrexate along with radiotherapy including total skin electron beam therapy while high-risk patients are managed most often with single agent or multiagent palliative chemotherapy. Patients who are intermediate- or high-risk need management by a multispecialty team at tertiary care centers.

    Full Text Available Knowledge is one of the most important resources of every company that must be effectively managed like any other resources. In addition to inter-organizational reasons, most of companies consider knowledge management and its effective usage as a leverage to be able to compete in their field. Although a lot of research has been conducted in this area, company's manager and decision makers fail in choosing the suitable knowledge management strategy which is the basis and initial step in their field of work. Therefore this research has been done with the goal of selecting the appropriate strategy for project oriented companies. Proposal of this research is to consider the main success factors of knowledge management, besides of its individual properties for each project, and also achievement of their reciprocal relationship through fuzzy DEMATEL method. For this purpose, according to previous studies, 6 main successful factors of knowledge management and 10 important properties of enterprise resource planning implementation project as secondary factors have been identified. Aforementioned project is related to one of the biggest distribution industry companies in Iran. Selected factors serve as assessment criterion for 3 Human-oriented strategy, system-oriented strategy, and dynamic strategy. Finally, by using fuzzy DEMATEL method, importance and efficacy of each strategy according to criteria has been identified.

    Subramani, Arun; Badruzzaman, Mohammad; Oppenheimer, Joan; Jacangelo, Joseph G

    2011-02-01

    Energy is a significant cost in the economics of desalinating waters, but water scarcity is driving the rapid expansion in global installed capacity of desalination facilities. Conventional fossil fuels have been utilized as their main energy source, but recent concerns over greenhouse gas (GHG) emissions have promoted global development and implementation of energy minimization strategies and cleaner energy supplies. In this paper, a comprehensive review of energy minimization strategies for membrane-based desalination processes and utilization of lower GHG emission renewable energy resources is presented. The review covers the utilization of energy efficient design, high efficiency pumping, energy recovery devices, advanced membrane materials (nanocomposite, nanotube, and biomimetic), innovative technologies (forward osmosis, ion concentration polarization, and capacitive deionization), and renewable energy resources (solar, wind, and geothermal). Utilization of energy efficient design combined with high efficiency pumping and energy recovery devices have proven effective in full-scale applications. Integration of advanced membrane materials and innovative technologies for desalination show promise but lack long-term operational data. Implementation of renewable energy resources depends upon geography-specific abundance, a feasible means of handling renewable energy power intermittency, and solving technological and economic scale-up and permitting issues.

  19. Weed management strategies for castor bean crops

    Directory of Open Access Journals (Sweden)

    Augusto Guerreiro Fontoura Costa

    2014-04-01

    Full Text Available Castor bean crops are agriculturally relevant due to the quality and versatility of their oil, both for the chemical industry and for biodiesel production. Proper weed management is important for both the cultivation and the yield of castor bean crops; therefore, the intention of the present work is to review pertinent information regarding weed management, including the studies regarding weed interference periods, chemical controls for use in different crop production systems and herbicide selectivity, for castor bean crops. Weed science research for castor bean crops is scarce. One of the main weed management challenges for castor bean crops is the absence of herbicides registered with the Ministry of Agriculture, Livestock and Food Supply (MALFS. Research for viable herbicides for weed control in castor bean crops should be directed by research and/or rural extension institutions, associations and farmers cooperatives, as well as by manufactures, for the registration of these selective herbicides, which would be primarily used to control eudicotyledons in castor bean crops. New studies involving the integration of weed control methods in castor bean also may increase the efficiency of weed management, for both small farmers using traditional crop methods in the Brazilian Northeast region, as well as for areas with the potential for large scale production, using conservation tillage systems, such as the no-tillage crop production system.

    Adaptive management is a well-established approach to managing natural resources, but there is little evidence demonstrating effectiveness of adaptive management over traditional management techniques. Peer-reviewed literature attempts to draw conclusions about adaptive management effectiveness using social perceptions, but those studies are largely restricted to employees of US federal organizations. To gain a more comprehensive insight into perceived adaptive management effectiveness, this study aimed to broaden the suite of disciplines, professional affiliations, and geographic backgrounds represented by both practitioners and scholars. A questionnaire contained a series of questions concerning factors that lead to or inhibit effective management, followed by another set of questions focused on adaptive management. Using a continuum representing strategies of both adaptive management and traditional management, respondents selected those strategies that they perceived as being effective. Overall, characteristics (i.e., strategies, stakeholders, and barriers) identified by respondents as contributing to effective management closely aligned with adaptive management. Responses were correlated to the type of adaptive management experience rather than an individual's discipline, occupational, or regional affiliation. In particular, perceptions of characteristics contributing to adaptive management effectiveness varied between respondents who identified as adaptive management scholars (i.e., no implementation experience) and adaptive management practitioners. Together, these results supported two concepts that make adaptive management effective: practitioners emphasized adaptive management's value as a long-term approach and scholars noted the importance of stakeholder involvement. Even so, more communication between practitioners and scholars regarding adaptive management effectiveness could promote interdisciplinary learning and problem solving for improved

    Funded by the U.S. Department of Energy in November 2013, a Building Energy Management Open Source Software (BEMOSS) platform was engineered to improve sensing and control of equipment in small- and medium-sized commercial buildings. According to the Energy Information Administration (EIA), small- (5,000 square feet or smaller) and medium-sized (between 5,001 to 50,000 square feet) commercial buildings constitute about 95% of all commercial buildings in the U.S. These buildings typically do not have Building Automation Systems (BAS) to monitor and control building operation. While commercial BAS solutions exist, including those from Siemens, Honeywell, Johnsons Controls and many more, they are not cost effective in the context of small- and medium-sized commercial buildings, and typically work with specific controller products from the same company. BEMOSS targets small and medium-sized commercial buildings to address this gap.

  6. Network switching strategy for energy conservation in heterogeneous networks.

    2017-01-01

    In heterogeneous networks (HetNets), the large-scale deployment of small base stations (BSs) together with traditional macro BSs is an economical and efficient solution that is employed to address the exponential growth in mobile data traffic. In dense HetNets, network switching, i.e., handovers, plays a critical role in connecting a mobile terminal (MT) to the best of all accessible networks. In the existing literature, a handover decision is made using various handover metrics such as the signal-to-noise ratio, data rate, and movement speed. However, there are few studies on handovers that focus on energy efficiency in HetNets. In this paper, we propose a handover strategy that helps to minimize energy consumption at BSs in HetNets without compromising the quality of service (QoS) of each MT. The proposed handover strategy aims to capture the effect of the stochastic behavior of handover parameters and the expected energy consumption due to handover execution when making a handover decision. To identify the validity of the proposed handover strategy, we formulate a handover problem as a constrained Markov decision process (CMDP), by which the effects of the stochastic behaviors of handover parameters and consequential handover energy consumption can be accurately reflected when making a handover decision. In the CMDP, the aim is to minimize the energy consumption to service an MT over the lifetime of its connection, and the constraint is to guarantee the QoS requirements of the MT given in terms of the transmission delay and call-dropping probability. We find an optimal policy for the CMDP using a combination of the Lagrangian method and value iteration. Simulation results verify the validity of the proposed handover strategy.

    Alessandro Serpi

    2017-11-01

    Full Text Available A novel optimal power and energy management (OPEM for centralized hybrid energy storage systems (HESS in microgrids is presented in this paper. The proposed OPEM aims at providing multiple grid services by suitably exploiting the different power/energy features of electrochemical batteries (B and supercapacitors (S. The first part of the paper focuses on the design and analysis of the proposed OPEM, by highlighting the advantages of employing hand-designed solutions based on Pontryagin’s minimum principle rather than resorting to pre-defined optimization tools. Particularly, the B power profile is synthesized optimally over a given time horizon in order to provide both peak shaving and reduced grid energy buffering, while S is employed in order to compensate for short-term forecasting errors and to prevent B from handling sudden and high-frequency power fluctuations. Both the B and S power profiles are computed in real-time in order to benefit from more accurate forecasting, as well as to support each other. Then, the effectiveness of the proposed OPEM is tested through numerical simulations, which have been carried out based on real data from the German island of Borkum. Particularly, an extensive and detailed performance analysis is performed by comparing OPEM with a frequency-based management strategy (FBM in order to highlight the superior performance achievable by the proposed OPEM in terms of both power and energy management and HESS exploitation.

    2006-09-01

    Commercial buildings account for a large portion of summer peak electric demand. Research results show that there is significant potential to reduce peak demand in commercial buildings through advanced control technologies and strategies. However, a better understanding of commercial buildings contribution to peak demand and the use of energy management and control systems is required to develop this demand response resource to its full potential. The main objectives of the study were: (1) To evaluate the size of contributions of peak demand commercial buildings in the U.S.; (2) To understand how commercial building control systems support energy efficiency and DR; and (3) To disseminate the results to the building owners, facility managers and building controls industry. In order to estimate the commercial buildings contribution to peak demand, two sources of data are used: (1) Commercial Building Energy Consumption Survey (CBECS) and (2) National Energy Modeling System (NEMS). These two sources indicate that commercial buildings noncoincidental peak demand is about 330GW. The project then focused on technologies and strategies that deliver energy efficiency and also target 5-10% of this peak. Based on a building operations perspective, a demand-side management framework with three main features: (1) daily energy efficiency, (2) daily peak load management and (3) dynamic, event-driven DR are outlined. A general description of DR, its benefits, and nationwide DR potential in commercial buildings are presented. Case studies involving these technologies and strategies are described. The findings of this project are shared with building owners, building controls industry, researchers and government entities through a webcast and their input is requested. Their input is presented in the appendix section of this report.

    1997-09-24

    The Global Nuclear Vision Project is examining, using scenario building techniques, a range of long-term nuclear energy futures. The exploration and assessment of optimal nuclear fuel-cycle and material strategies is an essential element of the study. To this end, an established global E{sup 3} (energy/economics/environmental) model has been adopted and modified with a simplified, but comprehensive and multi-regional, nuclear energy module. Consistent nuclear energy scenarios are constructed using this multi-regional E{sup 3} model, wherein future demands for nuclear power are projected in price competition with other energy sources under a wide range of long-term demographic (population, workforce size and productivity), economic (price-, population-, and income-determined demand for energy services, price- and population-modified GNP, resource depletion, world-market fossil energy prices), policy (taxes, tariffs, sanctions), and top-level technological (energy intensity and end-use efficiency improvements) drivers. Using the framework provided by the global E{sup 3} model, the impacts of both external and internal drivers are investigated. The ability to connect external and internal drivers through this modeling framework allows the study of impacts and tradeoffs between fossil- versus nuclear-fuel burning, that includes interactions between cost, environmental, proliferation, resource, and policy issues.

    Wildlife planning for renewable energy must cope with the uncertainties of potential wildlife impacts. Unfortunately, the environmental policies which instigate renewable energy and those which protect wildlife are not coherently aligned-creating a green versus green dilemma. Thus, climate mitigation efforts trigger renewable energy development, but then face substantial barriers from biodiversity protection instruments and practices. This article briefly reviews wind energy and wildlife interactions, highlighting the lively debated effects on bats. Today, planning and siting of renewable energy are guided by the precautionary principle in an attempt to carefully address wildlife challenges. However, this planning attitude creates limitations as it struggles to negotiate the aforementioned green versus green dilemma. More adaptive planning and management strategies and practices hold the potential to reconcile these discrepancies to some degree. This adaptive approach is discussed using facets of case studies from policy, planning, siting, and operational stages of wind energy in Germany and the United States, with one case showing adaptive planning in action for solar energy as well. This article attempts to highlight the benefits of more adaptive approaches as well as the possible shortcomings, such as reduced planning security for renewable energy developers. In conclusion, these studies show that adaptive planning and operation strategies can be designed to supplement and enhance the precautionary principle in wildlife planning for green energy.

    Full Text Available The installation of stationary super-capacitor energy storage system (ESS in metro systems can recycle the vehicle braking energy and improve the pantograph voltage profile. This paper aims to optimize the energy management, location, and size of stationary super-capacitor ESSes simultaneously and obtain the best economic efficiency and voltage profile of metro systems. Firstly, the simulation platform of an urban rail power supply system, which includes trains and super-capacitor energy storage systems, is established. Then, two evaluation functions from the perspectives of economic efficiency and voltage drop compensation are put forward. Ultimately, a novel optimization method that combines genetic algorithms and a simulation platform of urban rail power supply system is proposed, which can obtain the best energy management strategy, location, and size for ESSes simultaneously. With actual parameters of a Chinese metro line applied in the simulation comparison, certain optimal scheme of ESSes’ energy management strategy, location, and size obtained by a novel optimization method can achieve much better performance of metro systems from the perspectives of two evaluation functions. The simulation result shows that with the increase of weight coefficient, the optimal energy management strategy, locations and size of ESSes appear certain regularities, and the best compromise between economic efficiency and voltage drop compensation can be obtained by a novel optimization method, which can provide a valuable reference to subway company.

    Full Text Available Nowadays, striving to find an efficient way for developing or identifying appropriate knowledge management strategies in organizations has become so critical. Researchers and practitioners have attached great importance to information pyramids in organizations and have highlighted the lack of trained and skilled staff as a serious problem. On the other hand, having more flexibility at workplace, offering better service, and fulfilling customers' demands require a strategy for managing knowledge and its consequence. Knowledge management provides a wide range of different strategies and methods for identifying, creating, and sharing knowledge in organizations. This deep insight which consists of individual, organization’s experience, knowledge, and understanding helps organization respond to both internal and external stimuli and act in harmony. One fact which has seemingly achieved a consensus is the need for different strategies of knowledge management. Among the wide range of various and often unclear knowledge management strategies one can choose a strategy in a specific situation. The aim of this paper is to respond to strategic questions which emphasize competitive intelligence and internal knowledge retrieval system. The implications are discussed in detail.

Patients with epilepsy who become pregnant are at risk of complications, including changes in seizure frequency, maternal morbidity and mortality, and congenital anomalies due to antiepileptic drug exposure. Appropriate management of epilepsy during pregnancy may involve frequent monitoring of antiepileptic drug serum concentrations, potential preconception switching of antiepileptic medications, making dose adjustments, minimizing peak drug concentration with more frequent dosing, and avoiding potentially teratogenic medications. Ideally, preconception planning will be done to minimize risks to both the mother and fetus during pregnancy. It is important to recognize benefits and risks of current and emerging therapies, especially with revised pregnancy labeling in prescription drug product information. This review will outline risks for epilepsy during pregnancy, review various recommendations from leading organizations, and provide an evidence-based approach for managing patients with epilepsy before, during, and after pregnancy.

  18. Local energy governance in vermont: an analysis of energy system transition strategies and actor capacity

    Science.gov (United States)

    Rowse, Tarah

    While global, national, and regional efforts to address climate and energy challenges remain essential, local governments and community groups are playing an increasingly stronger and vital role. As an active state in energy system policy, planning and innovation, Vermont offers a testing ground for research into energy governance at the local level. A baseline understanding of the energy planning and energy organizing activities initiated at the local level can support efforts to foster a transition to a sustainable energy system in Vermont. Following an inductive, applied and participatory approach, and grounded in the fields of sustainability transitions, energy planning, and community energy, this research project identifies conditions for change, including opportunities and challenges, within Vermont energy system decision-making and governance at the local level. The following questions are posed: What are the main opportunities and challenges for sustainable energy development at the town level? How are towns approaching energy planning? What are the triggers that will facilitate a faster transition to alternative energy systems, energy efficiency initiatives, and localized approaches? In an effort to answer these questions two studies were conducted: 1) an analysis of municipal energy plans, and 2) a survey of local energy actors. Study 1 examined Vermont energy planning at the state and local level through a review and comparison of 40 municipal plan energy chapters with the state 2011 Comprehensive Energy Plan. On average, municipal plans mentioned just over half of the 24 high-level strategies identified in the Comprehensive Energy Plan. Areas of strong and weak agreement were examined. Increased state and regional interaction with municipal energy planners would support more holistic and coordinated energy planning. The study concludes that while municipalities are keenly aware of the importance of education and partnerships, stronger policy mechanisms

    Conlon, M K

    1997-11-01

    In a world of increased competition and changing consumer expectations, one of the keys to a fiscally sound health plan is having a dynamic marketing strategy that takes into account the shifting attitudes of consumers as managed care markets mature. The primary goal of any health plan marketing strategy should be the acquisition and retention of members. Providing cost-efficient and convenient service for enrollees, offering low or no deductibles, having convenient office locations, and minimizing paper-work are important elements of such a marketing strategy. Factors such as brand awareness and the perceived image of a health plan also are important considerations in acquiring and retaining market share. The relative importance of these consumer satisfaction criteria change as a managed care market evolves and matures. Financial and marketing managers, thus, should ascertain their market's stage of development and respond with appropriate marketing strategies.

    Tsung-Yung Chiu

    2012-12-01

    Full Text Available Global energy sources are gradually becoming scarce and prices are continually rising. Governments and businesses in various countries are actively developing technologies for energy management and developing new sources of energy. On 15 June 2011, the International Organization for Standardization (ISO announced the ISO 50001 standard for energy management systems. Organizations and enterprises are confronted with challenges associated with enhancing energy performance indicators, continuing to improve energy consumption efficiency, and managing third-party international certifications. This study conducted cases studies of businesses that have introduced an ISO 50001 energy management system by using an integration-energy-practice model to improve energy performance indicators and to complete the international auditing and certification procedures for ISO 50001 energy management systems. Based on case study results, the achievement rates for annual energy performance indicators increased, thereby enhancing the energy intensity efficiency. Establishing an integration-energy-practice model for introducing an ISO 50001 energy management system can efficiently meet demands for energy performance indicators and pass the international certification for ISO 50001 energy management systems. The proposed model efficiently provides enterprises with methods for developing sustainable energy management. It integrates internal and external technical resources to establish energy technology think tanks, for promoting successful technology and experiences to various sectors, thereby allowing enterprises to integrate energy management, increase energy efficiency, and meet the ISO 50001 international standard for energy management systems.

  1. A Single-Degree-of-Freedom Energy Optimization Strategy for Power-Split Hybrid Electric Vehicles

    Directory of Open Access Journals (Sweden)

    Chaoying Xia

    2017-07-01

    Full Text Available This paper presents a single-degree-of-freedom energy optimization strategy to solve the energy management problem existing in power-split hybrid electric vehicles (HEVs. The proposed strategy is based on a quadratic performance index, which is innovatively designed to simultaneously restrict the fluctuation of battery state of charge (SOC and reduce fuel consumption. An extended quadratic optimal control problem is formulated by approximating the fuel consumption rate as a quadratic polynomial of engine power. The approximated optimal control law is obtained by utilizing the solution properties of the Riccati equation and adjoint equation. It is easy to implement in real-time and the engineering significance is explained in details. In order to validate the effectiveness of the proposed strategy, the forward-facing vehicle simulation model is established based on the ADVISOR software (Version 2002, National Renewable Energy Laboratory, Golden, CO, USA. The simulation results show that there is only a little fuel consumption difference between the proposed strategy and the Pontryagin’s minimum principle (PMP-based global optimal strategy, and the proposed strategy also exhibits good adaptability under different initial battery SOC, cargo mass and road slope conditions.

  2. Anchorage strategies in geriatric hip fracture management

    2016-12-01

    Full Text Available There is an enormous humanitarian and socioeconomic need to improve the quality and effectiveness of care for patients with hip fracture. To reduce mechanical complications in the osteosynthesis of proximal femoral fractures, improved fixation techniques have been developed including blade or screw-anchor devices, locked minimally invasive or cement augmentation strategies. However, despite numerous innovations and advances regarding implant design and surgical techniques, systemic and mechanical complication rates remain high. Treatment success depends on secure implant fixation in often-osteoporotic bone as well as on patient-specific factors (fracture stability, bone quality, comorbidity, and gender and surgeon-related factors (experience, correct reduction, and optimal screw placement in the head/neck fragment. For fracture fixation, the anchorage of the lag screw within the femoral head plays a crucial role depending on the implant’s design. Meta-analyses and randomized controlled studies demonstrate that there is a strong trend towards arthroplasty treating geriatric femoral neck fractures. However, for young adults as well as older patients with less compromised bone quality, or in undisplaced fractures, head-preserving therapy is preferred as it is less invasive and associated with good functional results. This review summarizes the evidence for the internal fixation of femoral neck fractures and trochanteric femoral fractures in elderly patients. In addition, biomechanical considerations regarding implant anchorage in the femoral head including rotation, migration, and femoral neck shortening are made. Finally, cement augmentation strategies for hip fracture implants are evaluated critically.

    Fusarium wilt is caused by the fungal pathogens, Fusarium oxysporum or Fusarium solani. It is a devastating disease that affects many important food and vegetable crops and a major source of loss to farmers worldwide. Initial strategies developed to combat this devastating plant disease include the use of cultural, physical and chemical control. None of these strategies have been able to give the best results of completely ameliorating the situation except for the cultural method which is mainly preventive. A good knowledge of the nature, behaviour and environmental conditions of growth of the disease agent is very important to controlling the disease development in that case. Biological control has been shown to be an environmentally friendly alternative. It makes use of rhizospheric and endophytic microorganisms that can survive and compete favourably well with the Fusarium wilt pathogen. They include plant growth-promoting rhizobacteria (PGPR) such as Bacillus spp. and Pseudomonas spp. For PGPR to control or inhibit the growth of the Fusarium wilt pathogen, they make use of mechanisms such as indole acetic acid production, siderophore production, phosphate solublilization, systemic resistance induction and antifungal volatile production among others.

    Full Text Available In this paper we study energy cost saving strategies in power networks in presence of prosumers. Three tips are considered: (i distributed power network architecture, (ii peak energy shaving with the integration of prosumers’ contribution, (iii Electric vehicles self-charging by means of prosumers’ production. The proposed distributed power network architecture reduces significantly the transmission costs and can reduce significantly the global energy cost up to 42 percent. Different types of prosumer who use self-charging photovoltaic systems, are able to intelligently buy energy from, or sell it, to the power grid. Therein, prosumers interact in a distributed environment during the purchase or sale of electric power using a double auction with negotiation mechanism. Using a two-step combined learning and optimization scheme, each prosumer can learn its optimal bidding strategy and forecast its energy production, consumption and storage. Our simulation results, conducted for the region of Sicily in Italy, show that the integration of prosumers can reduce peak hour costs up to 19 percent and 6 percent for eligible prosumers with electric vehicles.

    Unlike fossil fuels, biomass is a renewable resource that can sequester carbon during growth, be converted to energy, and then re-grown. Biomass is also a flexible fuel that can service many end-uses. This paper explores the importance of bioenergy to potential future energy transformation and climate change management. Using a model comparison of fifteen models, we characterize and analyze future dependence on, and the value of, bioenergy in achieving potential long-run climate objectives—reducing radiative forcing to 3.7 and 2.8 W/m2 in 2100 (approximately 550 and 450 ppm carbon dioxide equivalent atmospheric concentrations). Model scenarios project, by 2050, bioenergy growth of 2 to 10% per annum reaching 5 to 35 percent of global primary energy, and by 2100, bioenergy becoming 15 to 50 percent of global primary energy. Non-OECD regions are projected to be the dominant suppliers of biomass, as well as consumers, with up to 35 percent of regional electricity from biopower by 2050, and up to 70 percent of regional liquid fuels from biofuels by 2050. Bioenergy is found to be valuable to many models with significant implications for mitigation costs and world consumption. The availability of bioenergy, in particular biomass with carbon dioxide capture and storage (BECCS), notably affects the cost-effective global emissions trajectory for climate management by accommodating prolonged near-term use of fossil fuels. We also find that models cost-effectively trade-off land carbon and nitrous oxide emissions for the long-run climate change management benefits of bioenergy. Overall, further evaluation of the viability of global large-scale bioenergy is merited.

    1997-06-01

    Hospital executives, steeped in hospital business traditions, sometimes fall victim to those traditions when planning their managed care strategies. They may fail to sufficiently evaluate their hospitals' market position or set appropriate priorities for their various business strategies. They may not recruit individuals with managed care expertise, develop effective marketing plans, or construct realistic physician networks. Some hospital executives may be ill-equipped to deal with cultural clashes and reluctant to share control of their managed care organizations with physicians. Or, they may not always understand the true nature of the arrangement they have entered into, the information and technology needs of the arrangement, and their own strategic advantages. Today's hospital executives must plan their managed care strategies carefully and execute them intelligently to ensure success.

    Demand side management strategies are key to meet future water and energy demands in urban contexts, promote water and energy efficiency in the residential sector, provide customized services and communications to consumers, and reduce utilities' costs. Smart metering technologies allow gathering high temporal and spatial resolution water and energy consumption data and support the development of data-driven models of consumers' behavior. Modelling and predicting resource consumption behavior is essential to inform demand management. Yet, analyzing big, smart metered, databases requires proper data mining and modelling techniques, in order to extract useful information supporting decision makers to spot end uses towards which water and energy efficiency or conservation efforts should be prioritized. In this study, we consider the following research questions: (i) how is it possible to extract representative consumers' personalities out of big smart metered water and energy data? (ii) are residential water and energy consumption profiles interconnected? (iii) Can we design customized water and energy demand management strategies based on the knowledge of water- energy demand profiles and other user-specific psychographic information? To address the above research questions, we contribute a data-driven approach to identify and model routines in water and energy consumers' behavior. We propose a novel customer segmentation procedure based on data-mining techniques. Our procedure consists of three steps: (i) extraction of typical water-energy consumption profiles for each household, (ii) profiles clustering based on their similarity, and (iii) evaluation of the influence of candidate explanatory variables on the identified clusters. The approach is tested onto a dataset of smart metered water and energy consumption data from over 1000 households in South California. Our methodology allows identifying heterogeneous groups of consumers from the studied sample, as well as

    2018-01-01

    Full Text Available Information and communication technologies (ICT offer immense potential to improve the energetic performance of buildings. Additionally, common building control systems are typically based on simple decision-making tools, which possess the ability to obtain controllable parameters for indoor temperatures. Nevertheless, the accuracy of such common building control systems is improvable with the integration of advanced decision-making techniques embedded into software and energy management tools. This paper presents the design of a building energy management system (BEMS, which is currently under development, and that makes use of artificial intelligence for the automated decision-making process required for optimal comfort of occupants and utilization of renewables for achieving energy-efficiency in buildings. The research falls under the scope of the H2020 project BREASER which implements fuzzy logic with the aim of governing the energy resources of a school in Turkey, which has been renovated with a ventilated façade with integrated renewable energy sources (RES. The BRESAER BEMS includes prediction techniques that increase the accuracy of common BEMS tools, and subsequent energy savings, while ensuring the indoor thermal comfort of the building occupants. In particular, weather forecast and simulation strategies are integrated into the functionalities of the overall system. By collecting the aforementioned information, the BEMS makes decisions according to a well-established selection of key performance indicators (KPIs with the objective of providing a quantitative comparable value to determine new actuation parameters.

    2012-07-01

    Full Text Available Disasters related to natural hazards have increased in the last few decades. This increment makes it necessary to develop non-structural risk prevention and mitigation measures to improve people’s safety. An effective non-structural measure that can improve the preparedness of the population is a locally adapted communication campaign that is focused on natural hazards. We have developed a hypothetical communication campaign for a specific area in the north of Italy, in which hydro-geological risk is of considerable importance. The content of the campaign is defined by the combination of the requirements of the law with the results of a survey conducted in the study area. The aim of the survey is to evaluate the level of risk perception among the residents, and their attitudes towards prevention activities. The operative procedure of the campaign is modeled on advertising strategies. The campaign is designed to reach each family, and it is aimed at affecting people’s everyday life through a horizontal communication strategy that involves flyers, billboards, umbrellas and a website. The use of umbrellas as a medium for the campaign is the key. People mostly use umbrellas when it rains. Rain is linked with hydrogeological risk. As the content of the campaign is printed on the umbrellas, each time people use these umbrellas, they remember the campaign. The campaign is integrated into a broader communication program that includes meetings with stakeholders, activities in schools, and public conferences. The final goal is to foster the creation of a shared knowledge about risk in the whole population.

    Dixon, John B; Dixon, Maureen E

    2006-01-01

    Obesity is a chronic relapsing disease requiring a similar long term approach to management as that of other chronic conditions. Management needs to be multifaceted aiming to achieve sustainable behavioural changes to physical activity and diet to alter the patient and family microenvironment to one favouring better weight control. A range of therapies including specific diets, calorie counting, meal replacements, very low calorie diets, pharmacotherapy, intragastric balloons and surgery can provide very useful additional benefit. Use of these should be guided by the extent of weight loss required to reduce BMI to an acceptable level with regard to the patient's ethnicity, risk and comorbid conditions. Patients need to set goals that are optimistic, but realistic, and understand the benefits of sustained modest weight loss and the likelihood of weight regain requiring repeat episodes of weight loss. Practitioners need to be informed about the efficacy of current therapies and their combinations to enhance choice of suitable methods for achieving the optimal weight loss required by the patient. They will also need to anticipate trigger points for renewed periods of weight loss in the event of weight regain, as relapse is likely but not a reason for abandoning the battle.

    Research has demonstrated that many students and some teachers do not consistently apply the conservation of energy principle when analyzing mechanical scenarios. In observing elementary and secondary teachers engaged in learning activities that require tracking and conserving energy, we find that challenges to energy conservation often arise in dissipative scenarios in which kinetic energy transforms into thermal energy (e.g., a ball rolls to a stop). We find that teachers expect that when they can see the motion associated with kinetic energy, they should be able to perceive the warmth associated with thermal energy. Their expectations are violated when the warmth produced is imperceptible. In these cases, teachers reject the idea that the kinetic energy transforms to thermal energy. Our observations suggest that apparent difficulties with energy conservation may have their roots in a strong and appropriate association between forms of energy and their perceptible indicators. We see teachers resolve these challenges by relating the original scenario to an exaggerated version in which the dissipated thermal energy is associated with perceptible warmth. Using these exaggerations, teachers infer that thermal energy is present to a lesser degree in the original scenario. They use this exaggeration strategy to track and conserve energy in dissipative scenarios.

    Energy assets and especially those deployed offshore are subject to a variety of harsh operational and environmental conditions which lead to deterioration of their performance and structural capacity over time. The aim of reduction of CAPEX in new installations shifts focus to operational management to monitor and assess performance of critical assets ensuring their fitness for service throughout their service life and also to provide appropriate and effective information towards requalification or other end of life scenarios, optimizing the OPEX. Over the last decades, the offshore oil & gas industry has developed and applied various approaches in operational management of assets through Structural Health and Condition Monitoring (SHM/CM) systems which can be, at a certain level, transferable to offshore renewable installations. This paper aims to highlight the key differences between offshore oil & gas and renewable energy assets from a structural integrity and reliability perspective, provide a comprehensive overview of different approaches that are available and applicable, and distinguish the benefits of such systems in the efficient operation of offshore energy assets.

  4. Dynamic management of integrated residential energy systems

    Muratori, Matteo

    dissertation presents a bottom-up highly resolved model of a generic residential energy eco-system in the United States. The model is able to capture the entire energy footprint of an individual household, to include all appliances, space conditioning systems, in-home charging of plug-in electric vehicles, and any other energy needs, viewing residential and transportation energy needs as an integrated continuum. The residential energy eco-system model is based on a novel bottom-up approach that quantifies consumer energy use behavior. The incorporation of stochastic consumer behaviors allows capturing the electricity consumption of each residential specific end-use, providing an accurate estimation of the actual amount of available controllable resources, and for a better understanding of the potential of residential demand response programs. A dynamic energy management framework is then proposed to manage electricity consumption inside each residential energy eco-system. Objective of the dynamic energy management framework is to optimize the scheduling of all the controllable appliances and in-home charging of plug-in electric vehicles to minimize cost. Such an automated energy management framework is used to simulate residential demand response programs, and evaluate their impact on the electric power infrastructure. For instance, time-varying electricity pricing might lead to synchronization of the individual residential demands, creating pronounced rebound peaks in the aggregate demand that are higher and steeper than the original demand peaks that the time-varying electricity pricing structure intended to eliminate. The modeling tools developed in this study can serve as a virtual laboratory for investigating fundamental economic and policy-related questions regarding the interplay of individual consumers with energy use. The models developed allow for evaluating the impact of different energy policies, technology adoption, and electricity price structures on the total

  5. An Energy-Efficient Sleep Strategy for Target Tracking Sensor Networks

    Full Text Available Energy efficiency is very important for sensor networks since sensor nodes have limited energy supply from battery. So far, many researches have been focused on this issue, while less emphasis was placed on the optimal sleep time of each node. This paper proposed an adaptive energy conservation strategy for target tracking based on a grid network structure, where each node autonomously determines when and if to sleep. It allows sensor nodes far away from targets to sleep to save energy and guarantee the tracking accuracy. The proposed approach extend network lifetime by adopting an adaptive sleep scheduling scheme that combines the local power management (PM and the adaptive coordinate PM strategies to schedule the activities of sensor nodes. And each node can choose an optimal sleep time so as to make system adaptive and energy-efficient. We show the performance of our approach in terms of energy drop, comparing it to a naive approach, dynamic PM with fixed sleep time and the coordinate PM strategies. From the experimental results, it is readily seen that the efficiency of the proposed approach.

  7. Real-Time Energy Management Control for Hybrid Electric Powertrains

    2013-01-01

    Full Text Available This paper focuses on embedded control of a hybrid powertrain concepts for mobile vehicle applications. Optimal robust control approach is used to develop a real-time energy management strategy. The main idea is to store the normally wasted mechanical regenerative energy in energy storage devices for later usage. The regenerative energy recovery opportunity exists in any condition where the speed of motion is in the opposite direction to the applied force or torque. This is the case when the vehicle is braking, decelerating, the motion is driven by gravitational force, or load driven. There are three main concepts for energy storing devices in hybrid vehicles: electric, hydraulic, and mechanical (flywheel. The real-time control challenge is to balance the system power demands from the engine and the hybrid storage device, without depleting the energy storage device or stalling the engine in any work cycle. In the worst-case scenario, only the engine is used and the hybrid system is completely disabled. A rule-based control algorithm is developed and is tuned for different work cycles and could be linked to a gain scheduling algorithm. A gain scheduling algorithm identifies the cycle being performed by the work machine and its position via GPS and maps both of them to the gains.

    2003-11-01

    The aim of this paper is to report on the findings from our research into the recent introduction of nurse practitioners in Alberta, Canada. Through an organizational research perspective, we identify the critical role of health care managers in developing a sustainable nurse practitioner role. Previous literature has focused on nurse practitioners themselves as the key factor in their integration into the health care system. Although they are qualified and organizationally well placed, managers of nurse practitioners have been overlooked as a critical part of implementation strategies. We interviewed 25 nurse practitioners and seven of their managers. Through our data analysis we identified three major challenges for managers: (1) clarifying the reallocation of tasks; (2) managing altered working relationships within the team; (3) continuing to manage the team in an evolving situation. Associated with these challenges, we propose leadership strategies that managers may find useful as they work through the consequences of introducing the nurse practitioner role. These strategies are: * encourage all team members to sort out 'who does what'; * ensure that task reallocation preserves job motivating properties; * give consideration to how tasks have been allocated when issues identified as 'personal conflict' arise; * pay attention to all perspectives of the working relationships within the team; * facilitate positive relationships between team members; * lead from a 'balcony' perspective; * work with the team to develop goals that are not over focused on the nurse practitioner; * regularly share with other managers the experiences and lessons learned in introducing nurse practitioners. For managers to be most effective, they need to address three challenges that are of a managerial, not clinical, nature. By implementing specific leadership strategies, managers of nurse practitioners can facilitate the introduction of the new role and improve its sustainability in

  11. Assessing Fishers' Support of Striped Bass Management Strategies.

    Robert D Murphy

    Full Text Available Incorporating the perspectives and insights of stakeholders is an essential component of ecosystem-based fisheries management, such that policy strategies should account for the diverse interests of various groups of anglers to enhance their efficacy. Here we assessed fishing stakeholders' perceptions on the management of Atlantic striped bass (Morone saxatilis and receptiveness to potential future regulations using an online survey of recreational and commercial fishers in Massachusetts and Connecticut (USA. Our results indicate that most fishers harbored adequate to positive perceptions of current striped bass management policies when asked to grade their state's management regime. Yet, subtle differences in perceptions existed between recreational and commercial fishers, as well as across individuals with differing levels of fishing experience, resource dependency, and tournament participation. Recreational fishers in both states were generally supportive or neutral towards potential management actions including slot limits (71% and mandated circle hooks to reduce mortality of released fish (74%, but less supportive of reduced recreational bag limits (51%. Although commercial anglers were typically less supportive of management changes than their recreational counterparts, the majority were still supportive of slot limits (54% and mandated use of circle hooks (56%. Our study suggests that both recreational and commercial fishers are generally supportive of additional management strategies aimed at sustaining healthy striped bass populations and agree on a variety of strategies. However, both stakeholder groups were less supportive of harvest reductions, which is the most direct measure of reducing mortality available to fisheries managers. By revealing factors that influence stakeholders' support or willingness to comply with management strategies, studies such as ours can help managers identify potential stakeholder support for or conflicts

  12. Maximum wind energy extraction strategies using power electronic converters

    Wang, Quincy Qing

    2003-10-01

    This thesis focuses on maximum wind energy extraction strategies for achieving the highest energy output of variable speed wind turbine power generation systems. Power electronic converters and controls provide the basic platform to accomplish the research of this thesis in both hardware and software aspects. In order to send wind energy to a utility grid, a variable speed wind turbine requires a power electronic converter to convert a variable voltage variable frequency source into a fixed voltage fixed frequency supply. Generic single-phase and three-phase converter topologies, converter control methods for wind power generation, as well as the developed direct drive generator, are introduced in the thesis for establishing variable-speed wind energy conversion systems. Variable speed wind power generation system modeling and simulation are essential methods both for understanding the system behavior and for developing advanced system control strategies. Wind generation system components, including wind turbine, 1-phase IGBT inverter, 3-phase IGBT inverter, synchronous generator, and rectifier, are modeled in this thesis using MATLAB/SIMULINK. The simulation results have been verified by a commercial simulation software package, PSIM, and confirmed by field test results. Since the dynamic time constants for these individual models are much different, a creative approach has also been developed in this thesis to combine these models for entire wind power generation system simulation. An advanced maximum wind energy extraction strategy relies not only on proper system hardware design, but also on sophisticated software control algorithms. Based on literature review and computer simulation on wind turbine control algorithms, an intelligent maximum wind energy extraction control algorithm is proposed in this thesis. This algorithm has a unique on-line adaptation and optimization capability, which is able to achieve maximum wind energy conversion efficiency through

    We present a measurement study of the energy consumption of an operator-side digital subscriber line (DSL) board under various conditions of data rate and power spectral density, with and without vectoring. The results highlight practical opportunities and challenges for optimizing rate-power-stability tradeoffs in DSL access systems, complementing simulation-based studies focused on energy reduction through spectral optimization. We validate models for line board consumption that can be tied with line driver consumption based on the aggregate transmit power of each line, and demonstrate that near-optimal rate-power-stability tradeoffs can be obtained through external line management of data rate, Signal-to-Noise-Ratio margin and power spectral density parameters. © 2013 IEEE.

    Full Text Available An assessment of the available sources of energy in selected rural areas of Benue State, Nigeria was undertaken with a view to evaluate their consumption pattern. Systematic random sampling was used to sample 144 households. Well structured questionnaire and measuring equipments were used to obtain our data. The analysis on age, energy resources in the selected areas and consumption pattern were based on descriptive statistics. Analysis to determine effect of income and household size on quantities of fuel usage was done using models of regression and analysis of variance (ANOVA. The findings revealed that 92.4 % of the respondents were above 50 years old on average and about 37 % had a household size of 11 members. The rural populace rely more on fuel wood as their sources of energy. The estimated average daily fuel wood and kerosene consumption per household ranged between 9–20 kg and 0.02 - 0.1 litres respectively. The average annual income of the respondents range between 270 – 800 US dollar (#40,000 - #120,000 Nigeria currency, which shows that majority of these rural populace lives below poverty line. The correlation coefficients between household size and quantities of fuel wood and kerosene consumed by respondents are 0.914 and 0.812 respectively so their relationships are statistically significant at 5 % probability level. Relationships between their household income and quantities of kerosene and fuel wood used have correlation coefficients of 0.107 and 0.109 respectively, which are not statistically significant at 5 % probability level. Solar energy systems need be developed for use in the rural areas for efficient resources management and utilization.

    The promise of the Next Generation Air Transportation System (NextGen) is strongly tied to the concept of trajectory-based operations in the national airspace system. Existing efforts to develop trajectory management concepts are largely focused on individual trajectories, optimized independently, then de-conflicted among each other, and individually re-optimized, as possible. The benefits in capacity, fuel, and time are valuable, though perhaps could be greater through alternative strategies. The concept of agent-based trajectories offers a strategy for automation of simultaneous multiple trajectory management. The anticipated result of the strategy would be dynamic management of multiple trajectories with interacting and interdependent outcomes that satisfy multiple, conflicting constraints. These constraints would include the business case for operators, the capacity case for the Air Navigation Service Provider (ANSP), and the environmental case for noise and emissions. The benefits in capacity, fuel, and time might be improved over those possible under individual trajectory management approaches. The proposed approach relies on computational agent-based modeling (ABM), combinatorial mathematics, as well as application of "traffic physics" concepts to the challenge, and modeling and simulation capabilities. The proposed strategy could support transforming air traffic control from managing individual aircraft behaviors to managing systemic behavior of air traffic in the NAS. A system built on the approach could provide the ability to know when regions of airspace approach being "full," that is, having non-viable local solution space for optimizing trajectories in advance.

    2014-12-01

    Full Text Available This paper aims to reflect the importance of a knowledge management strategy for organisations facing organisational change, as response to crisis. As resource for development, for sure knowledge becomes an inexhaustible power. It is also one of the most important forms of capital - the foundation for innovation and also the drivers that lead to growth and expansion. An organization cannot compete with others in this ever-changing environment without proper knowledge and lack of capacity for renewal. Many managers would like to have a strategic approach in preparing the organisation to avoid crisis. There is a lack of strategic information management and the effect is the degradation of information resources and failure in strengthening employee’s potential. It is vital for the companies to develop a dynamic knowledge management strategy to be integrated into the organization, enhancing the performance of the system and processes. However, organizations need to see knowledge management as a strategy, because knowledge is the key to making the right decisions in guiding the organization. One of the key benefits of approaching knowledge management strategy within organisations is its positive impact on organisational performance, ensuring not only the survival during crisis but even providing a competitive advantage.

    Minimal invasive approaches to managing caries, such as partial caries removal techniques, are showing increasing evidence of improved outcomes over the conventional complete caries removal. There is also increasing interest in techniques where no caries is removed. We present the 1-yr results of clinical efficacy for 3 caries management options for occlusoproximal cavitated lesions in primary molars: conventional restorations (CR; complete caries removal and compomer restoration), Hall technique (HT; no caries removal, sealing in with stainless steel crowns), and nonrestorative caries treatment (NRCT; no caries removal, opening up the cavity, teaching brushing and fluoride application). In sum, 169 children (3-8 yr old; mean, 5.56 ± 1.45 yr) were enrolled in this secondary care–based, 3-arm, parallel-group, randomized clinical trial. Treatments were carried out by specialist pediatric dentists or postgraduate trainees. One lesion per child received CR, HT, or NRCT. Outcome measures were clinical failure rates, grouped as minor failure (restoration loss/need for replacement, reversible pulpitis, caries progression, etc.) and major failure (irreversible pulpitis, abscess, etc.). There were 148 children (87.6%) with a minimum follow-up of 11 mo (mean, 12.23 ± 0.98 mo). Twenty teeth were recorded as having at least 1 minor failure: NRCT, n = 8 (5%); CR, n = 11 (7%); HT, n = 1 (1%) (p = .002, 95% CI = 0.001 to 0.003). Only the comparison between NRCT and CR showed no significant difference (p = .79, 95% CI = 0.78 to 0.80). Nine (6%) experienced at least 1 major failure: NRCT, n = 4 (2%); CR, n = 5 (3%); HT, n = 0 (0%) (p = .002, 95% CI = 0.001 to 0.003). Individual comparison of NRCT and CR showed no statistically significant difference in major failures (p = .75, 95% CI = 0.73 to 0.76). Success and failure rates were not significantly affected by pediatric dentists’ level of experience (p = .13, 95% CI = 0.12 to 0.14). The HT was significantly more successful

    2011-12-01

    Full Text Available The Intergovernmental Panel on Climate Change (IPCC has identified a number of soil-management strategies that can be implemented to reduce GHG emissions. However, before deciding which of these strategies are most appropriate in any given situation, it is important to investigate how these strategies affect other aspects of sustainable development. For instance, some attempts to sequester carbon in the landscape could alter the soil's capacity to filter water. Alternatively, other strategies could unintentionally increase net energy consumption through greater fertilizer use. Focusing specifically on opportunities to implement soil-management strategies in the European Union (EU, we discuss the synergies and trade-offs of those strategies with respect to water resources management and energy security. The focus of the analysis is two-fold: first, we analyze the net benefit of strategies such as crop management, nutrient management, tillage and residue management, water management, and bioenergy vis-a-vis their implications for water resources and energy security; second, we undertake an assessment of the EU's relevant policy frameworks to assess whether the potential synergies from various soil-management strategies are being encouraged or, conversely, where perverse outcomes or trade-offs are likely. Our findings suggest there is much scope to encourage soil-management strategies in Europe that would mitigate greenhouse gas emissions, but these synergies are currently not fully exploited at the EU policy level. We identify a number of options for better policy integration among the Common Agricultural Policy, the Water Framework Directive, and the Climate Action and Renewable Energy Package.
