  3. Philippines revises power plans

    Energy Technology Data Exchange (ETDEWEB)

    Hayes, D.

    1988-02-01

    Following an unexpected surge in electricity demand the Philippines has revised its medium term power development programme. The sharp increase in electricity consumption follows three years of slack demand due to civil disturbances before the end of the Macros administration and the election of Corazon Aquino as President in 1986. Originally, the Aquino government's medium term power development plans called for about 500MW of generating capacity to be installed between 1986 and 1992. The three proposed plants were scheduled for commissioning in 1991 and 1992. However, a spurt in power demand growth during the past nine months has caused concern among industrialists that power shortages could occur by the end of the decade. So additional capacity will be installed to prevent an anticipated shortfall in electricity supplies by the early 1990s.

    NASA's Radioisotope Power Systems (RPS) Program continues to plan and implement content to enable planetary exploration where such systems could be needed, and to prepare more advanced RPS technology for possible infusion into future power systems. The 2014-2015 period saw significant changes, and strong progress. Achievements of near-term objectives have enabled definition of a clear path forward in which payoffs from research investments and other sustaining efforts can be applied. The future implementation path is expected to yield a higher-performing thermoelectric generator design, a more isotope-fuel efficient system concept design, and a robust RPS infrastructure maintained effectively within both NASA and the Department of Energy. This paper describes recent work with an eye towards the future plans that result from these achievements.

    2008-07-01

    This paper presents a method that combines the electricity market and power flow models and describes how they were used for transmission grid planning with large amounts of wind power in the power system. The market model (EMPS) is used by the Nordic Transmission System Operators (TSO), producers and market analysts. There are different possibilities to model the wind power in EMPS and different ways lead to different results. The paper presents a method for analysing the impacts of wind power by modifying the wind power representation in the market model. The paper presents how the purpose of the study (e.g. energy balance or dynamic impacts) should be taken into account when deciding which wind power modelling method to use. Additionally, an example of utilizing the models for planning the Nordic grid is described in this paper. The combined market and power flow software (Samlast) also has grid models inside the price areas and therefore it enables further grid analysis such as dynamic simulations. The paper presents the results of the combined model and different ways of using the results. The combined model can be used both for energy based grid analysis and for support of power flow analysis. The results show that there is a need of transmission grid investments in Finland if 4 GW wind power would be installed. (orig.)

  16. Strategic planning for power system restorations

    Energy Technology Data Exchange (ETDEWEB)

    Bent, Russell W [Los Alamos National Laboratory; Van Hententyck, Pascal [BROWN UNIV.; Coffrin, Carleton [BROWN UNIV.

    2010-10-12

    This paper considers the power system restoration planning problem (PSRPP) for disaster recovery, a fundamental problem faced by all populated areas. PSRPPs are complex stochastic optimization problems that combine resource allocation, warehouse location, and vehicle routing considerations. Furthermore, electrical power systems are complex systems whose behavior can only be determined by physics simulations. Moreover, these problems must be solved under tight runtime constraints to be practical in real-world disaster situations. This work is three fold: (1) it formalizes the specification of PSRPPs; (2) introduces a simple optimization-simulation hybridization necessary for solving PSRPPs; and (3) presents a complete restoration algorithm that utilizes the strengths of mixed integer programming, constraint programming, and large neighborhood search. This paper studied a novel problem in the field of humanitarian logistics, the Power System Restoration Problem (PSRPP). The PSRPP models the strategic planning process for post disaster power system recovery. The paper proposed a multi-stage stochastic hybrid optimization algorithm that yields high quality solutions to real-world benchmarks provided by Los Alamos National Laboratory (LANL). The algorithm uses a variety of technologies, including MIP, constraint programming, and large neighborhood search, to exploit the structure of each individual optimization subproblem. The experimental results on hurricane disaster benchmarks indicate that the algorithm is practical from a computational standpoint and produce significant improvements over existing relief delivery procedures.

    Guirl, Robert; Munroe, James; Scott, Walter

    1990-01-01

    This paper discussed the development of an integrated Orbiter Auxiliary Power Unit (APU) and Improved APU (IAPU) Flight Suuport Plan. The plan identifies hardware requirements for continued support of flight activities for the Space Shuttle Orbiter fleet. Each Orbiter vehicle has three APUs that provide power to the hydraulic system for flight control surface actuation, engine gimbaling, landing gear deployment, braking, and steering. The APUs contain hardware that has been found over the course of development and flight history to have operating time and on-vehicle exposure time limits. These APUs will be replaced by IAPUs with enhanced operating lives on a vehicle-by-vehicle basis during scheduled Orbiter modification periods. This Flight Support Plan is used by program management, engineering, logistics, contracts, and procurement groups to establish optimum use of available hardware and replacement quantities and delivery requirements for APUs until vehicle modifications and incorporation of IAPUs. Changes to the flight manifest and program delays are evaluated relative to their impact on hardware availability.

  18. Solar power deployment: Forecasting and planning

    Science.gov (United States)

    Alanazi, Mohana

    The rapid growth of Photovoltaic (PV) technology has been very visible over the past decade. Recently, the penetration of PV plants to the existing grid has significantly increased. Such increase in the integration of solar energy has brought attention to the solar irradiance forecasting. This thesis presents a thorough research of PV technology, how solar power can be forecasted, and PV planning under uncertainty. Over the last decade, the PV was one of the fastest growing renewable energy technologies. However, the PV system output varies based on weather conditions. Due to the variability and the uncertainty of solar power, the integration of the electricity generated by PV system is considered one of the challenges that have confronted the PV system. This thesis proposes a new forecasting method to reduce the uncertainty of the PV output so the power operator will be able to accommodate its variability. The new forecasting method proposes different processes to be undertaken before the data is fed to the forecasting model. The method converts the data sets included in the forecasting from non-stationary data to a stationary data by applying different processes including: removing the offset, removing night time solar values, and normalization. The new forecasting method aims to reduce the forecasting error and analyzes the error effect on the long term planning through calculating the payback period considering different errors.

  1. Improving acceptance in wind power planning

    Energy Technology Data Exchange (ETDEWEB)

    Hammarlund, K. [Lund Univ. (Sweden). Dept. of Social and Economic Geography

    1996-12-01

    This paper presents important factors and planning procedures for public acceptance of wind power. Opinion surveys in Sweden show that acceptance is connected to the concept of utility rather than the aesthetic values. If wind turbines are confined by the authorities to marginal areas, they will not earn their rightful place in the landscape by being of use. A positive attitude in general promotes a positive experience of the effects of wind turbines. It is therefore essential to establish a sense of cooperation between the project management and the public. An open dialogue and continuous information will increase the possibilities for acceptance of future development. We must establish new codes of practice in permit processing because policies today contains ideological and practical contradictions between development and preservation of landscapes. 16 refs, 2 tabs

    1997-12-31

    The awareness of the problem of avian fatalities at large scale wind energy developments first emerged in the late 1980`s at the Altamont Pass Wind Resource Area (WRA) in Central California. Observations of dead raptors at the Altamont Pass WRA triggered concern on the part of regulatory agencies, environmental/conservation groups, resource agencies, and wind and electric utility industries. This led the California Energy Commission staff, along with the planning departments of Alameda, Contra Costa, and Solano counties, to commission a study of bird mortality at the Altamont Pass WRA. In addition to the Altamont Pass WRA, other studies and observations have established that windplants kill birds. Depending upon the specific factors, this may or may not be a serious problem. The current level of scrutiny and caution exhibited during the permitting of a new windplant development in the United States results in costly delays and studies. This is occurring during a highly competitive period for electrical production companies in the USA. Clarification of the bird fatality issue is needed to bring it into perspective. This means standardizing metrics, defining terms, and recommending methods to be used in addressing or studying wind energy/bird interactions.

    At present there are big challenges for power suppliers because of running up renewals of German power plant parks. In addition to foreseeable bottlenecks in supply of plant components and plant systems there also has to be found a solution for procurement and execution of engineering capacities. For coal-fired large-scale power plants the realization of the project is provided in builders own direction in association with purchase of single components and systems in cooperation with an engineering company for the overall planning. The technical contribution describes the basic possibilities of development view as well as the assignments for overall planning as 'owners engineer' in project phases. Part and parcel of the project success is a clear task sharing between building owners and designers as well as the application of data bases and planning tools with a wide range acceptance. The complexity and multitude of the involved participant is allowed for the essential assignment of highly effective and efficiently planning software. In the process it is apparently that specific major project requirements just can be observed, by ad hoc developed applications such as a document management system, stereoscopic planning or a based on web project platform. The possibilities of the information technology advise a central data handling to potentiate paperless engineering. For this purpose an effective and safe IT-structure must be made available. By dint of this IT-structure with an Information-Lifecycle-Management (ILM) also the operating stage can be included already. (orig.)

    2009-01-01

    Rural power network planning is a complicated nonlinear optimized combination problem which based on load forecasting results, and its actual load is affected by many uncertain factors, which influenced optimization results of rural power network planning. To solve the problems, the interval algorithm was used to modify the initial search method of uncertainty load mathematics model in rural network planning. Meanwhile, the genetic/tabu search combination algorithm was adopted to optimize the initialized network. The sample analysis results showed that compared with the certainty planning, the improved method was suitable for urban medium-voltage distribution network planning with consideration of uncertainty load and the planning results conformed to the reality.

    2016-08-01

    Worldwide thrust is being provided in generation of electricity from wind. Planning for the developmental needs of wind based power has to be consistent with the objective and basic framework of overall resource planning. The operational issues associated with the integration of wind power must be addressed at the planning stage. Lack of co-ordinated planning of wind turbine generators, conventional generating units and expansion of the transmission system may lead to curtailment of wind power due to transmission inadequacy or operational constraints. This paper presents a generation expansion planning model taking into account fuel transportation and power transmission constraints, while addressing the operational issues associated with the high penetration of wind power. For analyzing the operational issues, security constrained unit commitment algorithm is embedded in the integrated generation and transmission expansion planning model. The integrated generation and transmission expansion planning problem has been formulated as a mixed integer linear problem involving both binary and continuous variables in GAMS. The model has been applied to the expansion planning of a real system to illustrate the proposed approach.

    2015-12-01

    Full Text Available Key problems of the regional electric power supply systems are examined. These problems result from a lack of regulated interaction mechanisms for uniting the different entities’ resources aimed at the realization of investment activities. One of the main problems of the power supply industry is physical and moral aging of both generating and networking equipment. In the article, the necessity of management system formation to control the development of power sector has been proved. The deficiencies of the modern investment procedure in power companies are described. The absence of continuity between the regional and local strategic planning documents and investment planning of a power company has been found out. The possibility to develop a new mechanism for attracting investment has been proposed. The regulation of joint activities to implement the development program for the regional power supply industry has been proposed. The management system to develop the Russian power industry has been proposed. The comparative analysis of generating capacity development mechanisms has been carried out, such as capacity supply agreement (CSA, investment support mechanism (ISM, and long-term power market (LPM. The interaction procedure of the planning of the power supply infrastructure development has been described. The mechanism connecting the state sectoral and regional planning and corporate planning of power supply infrastructure development has been proposed. The regional aspects of industrial policy and its legislative support have been considered. To successfully implement the public-private-partnership (PPP projects, it is necessary to create the effective PPP model within the federal and regional legislation framework; to develop the financial model providing the recoverability of investments; to provide a mutually beneficial cooperation between executive bodies and private investors.

    This document shows the importance of policies for electric energy savings and efficient energy utilization in power planning. The contributions of economic, social, and environmental items were evaluated according to their financial effects in the delay of investments, reduction of production costs and decrement of environmental emissions. The case study is Baja California, Mexico; this system has a unique primary source: geothermal energy. Whether analyzing the planning as usual or planning from the supply side, the forecast for 2005-2025 indicates that 4500 MW additional installed capacity will be required (3-times current capacity), representing an investment that will emit 12.7 Mton per year of CO{sub 2} to the atmosphere and will cost US$2.8 billion. Systemic planning that incorporates polices of energy savings and efficiency allows the reduction of investments and pollutant emissions. For example, a reduction of 20% in the growth trend of the electricity consumption in the industrial customers would save US$10.4 billion over the next 20 years, with a potential reduction of 1.6 Mton/year of CO{sub 2}. The increase in geothermal power generation is also attractive, and it can be combined with the reduction of use and energy losses of utilities, which would save US$13.5 billion and prevent the discharge of 8.5 Mton/year of CO{sub 2}. - Highlights: > We contrast power planning methods for supply electricity for economy development. > Importance of policies for electricity savings and efficient use in power planning. > Systemic planning facilitates decision-making process for electricity optimization. > Supply-side planning will cause climb in prices and loss of energy self-sufficiency. > Power planning should be immersed in an environment of appropriate energy policies.

    2004-07-01

    During the last two decades electric power generation industry in many countries and regions around the world has undergone a significant transformation from being a centrally coordinated monopoly to a deregulated liberalized market. In the majority of those countries, competition has been introduced through the adoption of a competitive wholesale electricity spot market. Short-term efficiency of power generators under competitive environment has attracted considerable effort from researchers, while long-term investment performance has received less attention. In this context, the paper aims to serve as a comprehensive review basis for generation planning methods applied in a competitive electric power generation market. The traditional modeling techniques developed for generation expansion planning under monopoly are initially presented in an effort to assess the evolution of generation planning according to the evolution of the structure of the electric power market.

    Investigations of the impact of high-altitude electromagnetic pulse (HEMP) on electric power systems and electrical equipment have revealed that HEMP creates both misoperation and failures. These events result from both the early time E[sub 1] (steep-front pulse) component and the late time E[sub 3] (geomagnetic perturbations) component of HEMP. In this report a HEMP event is viewed in terms of its marginal impact over classical power system disturbances by considering the unique properties and consequences of HEMP. This report focuses on system-wide electrical component failures and their potential consequences from HEMP. In particular, the effectiveness of planning and operating procedures for electric systems is evaluated while under the influence of HEMP. This assessment relies on published data and characterizes utilities using the North American Electric Reliability Council's regions and guidelines to model electric power system planning and operations. Key issues addressed by the report include how electric power systems are affected by HEMP and what actions electric utilities can initiate to reduce the consequences of HEMP. The report also reviews the salient features of earlier HEMP studies and projects, examines technology trends in the electric power industry which are affected by HEMP, characterizes the vulnerability of power systems to HEMP, and explores the capability of electric systems to recover from a HEMP event.

  9. Integrating Photovoltaic Systems in Power System: Power Quality Impacts and Optimal Planning Challenges

    Directory of Open Access Journals (Sweden)

    Aida Fazliana Abdul Kadir

    2014-01-01

    Full Text Available This paper is an overview of some of the main issues in photovoltaic based distributed generation (PVDG. A discussion of the harmonic distortion produced by PVDG units is presented. The maximum permissible penetration level of PVDG in distribution system is also considered. The general procedures of optimal planning for PVDG placement and sizing are also explained in this paper. The result of this review shows that there are different challenges for integrating PVDG in the power systems. One of these challenges is integrated system reliability whereas the amount of power produced by renewable energy source is consistent. Thus, the high penetration of PVDG into grid can decrease the reliability of the power system network. On the other hand, power quality is considered one of the challenges of PVDG whereas the high penetration of PVDGs can lead to more harmonic propagation into the power system network. In addition to that, voltage fluctuation of the integrated PVDG and reverse power flow are two important challenges to this technology. Finally, protection of power system with integrated PVDG is one of the most critical challenges to this technology as the current protection schemes are designed for unidirectional not bidirectional power flow pattern.

    Since a few years, French wind power has undertaken an unprecedented development. Few turbines are in place (756 MW), but the overall granted capacity amounts to about 2.7 GW. The administrative territory of Aveyron, one of the best wind power potential in the Country, is an interesting case for understanding the ways in which industrial wind power is being developed and regulated in France. The paper presents Aveyron wind power development by dividing it into three periods. For each period, we also sketch national developments in wind power policy.Between 1996 and 2000, Aveyron was one of the few places selected for developing wind parks under the French 'Eole 2005' call for tender. Between 2000 and 2005, French regulation shifted to fixed tariffs for small wind parks (less than 12 MW). The lack of planning approach provided developers with a window for profits. Numerous projects of small parks were submitted for development authorisation, overflowing the local administration. During the year of 2003, a new law on urbanism provided some rules for individual project developments without answering the key issue of territorial planning. In Aveyron, a local scheme devised by the decentralized branches of the State had a limited reach due to the lack of mandatory status and concentration.In July 2005, a new Energy Law imposed the design of Wind Power Development Zones (WPDZ) as a condition for tariff benefit (starting July 2007). WPDZ appeared to local actors as a promising tool but it came late. Many projects were already granted with construction permits.

    The goal of NASA's Radioisotope Power Systems (RPS) Program is to make RPS ready and available to support the exploration of the solar system in environments where the use of conventional solar or chemical power generation is impractical or impossible to meet the needs of the missions. To meet this goal, the RPS Program, working closely with the Department of Energy, performs mission and system studies (such as the recently released Nuclear Power Assessment Study), assesses the readiness of promising technologies to infuse in future generators, assesses the sustainment of key RPS capabilities and knowledge, forecasts and tracks the Program's budgetary needs, and disseminates current information about RPS to the community of potential users. This process has been refined and used to determine the current content of the RPS Program's portfolio. This portfolio currently includes an effort to mature advanced thermoelectric technology for possible integration into an enhanced Multi-Mission Radioisotope Generator (eMMRTG), sustainment and production of the currently deployed MMRTG, and technology investments that could lead to a future Stirling Radioisotope Generator (SRG). This paper describes the program planning processes that have been used, the currently available MMRTG, and one of the potential future systems, the eMMRTG.

    With the energy systems of many African countries dominated by fossil-fuel sources that are vulnerable to global price volatility, regional and intra-continental power systems with high shares of renewable energy can provide least-cost option to support continued economic growth and address the continent’s acute energy access problem. Unlocking Africa’s huge renewable energy potential could help to take many people out of poverty, while ensuring the uptake of sustainable technologies for the continent’s long-term development. The report examines the ''renewable scenario'' based on a modelling tool developed by IRENA and tested in cooperation with the South African National Energy Development Institute (SANEDI) and the Southern African Development Community (SADC). Initial results from the System Planning and Test (SPLAT) model show that the share of renewable technologies in Southern Africa could increase from the current 10% to as much as 46% in 2030, with 20% of decentralised capacity coming from renewable sources and nearly 80% of the envisaged capacity additions between 2010 and 2030 being provided by renewable energy technologies. Deployment and export of hydropower from the Democratic Republic of Congo’s Inga hydropower project to the SADC region would significantly reduce average electricity generation costs. Analysis using SPLAT – along with a similar model developed for West Africa – can provide valuable input for regional dialogue and energy projects such as the East and Southern Africa Clean Energy Corridor and the Programme for Infrastructure and Development in Africa (PIDA). IRENA, together with partner organisations, has started plans to set up capacity building and development support for energy system modelling and planning for greater integration of renewables in Africa. IRENA is also completing a similar model and study for East Africa and intends to extend this work to Central and North Africa.

Unlocking Africa’s huge renewable energy potential could help to take many people out of poverty, while ensuring the uptake of sustainable technologies for the continent’s long-term development. The report examines a ''renewable scenario'' based on a modelling tool developed by IRENA and tested with assistance from the Economic Community of West African States (ECOWAS). Initial results from the ECOWAS Renewable Energy Planning (EREP) model for continental ECOWAS countries show that the share of renewable technologies in the region could increase from the current 22% of electricity generation to as much as 52% in 2030, provided that the cost of these technologies continues to fall and fossil fuel prices continue to rise. In this scenario, nearly half of the envisaged capacity additions between 2010 and 2030 would be with renewable technologies. Analysis using EREP – along with a similar model developed for Southern Africa – can provide valuable input for regional dialogue and energy projects such as the East and Southern Africa Clean Energy Corridor and the Programme for Infrastructure and Development in Africa (PIDA).

    In this report, NVE (Norwegian Water Resources and Energy Administration) presents a survey of how many electric utility companies in Norway that have worked out local power system plans, ie plans for the distribution grid. An inquiry was made among over 200 Norwegian utilities in order to clarify the status of such planning per 1997. So far NVE is not authorized to require that anybody shall take up local power system planning, but the goal is to provide local motivation for such planning. NVE has also wanted to focus on some of the problems connected with local power planning. In 1997, a project will be done on end-user measures and local power system planning. Power- and energy reducing end-user measures may be efficient ways of reducing grid investments in a supply region and should be more strongly incorporated into grid planning. 39% of the utilities already have local power system plans, 15% did not answer the inquiry, 16% did not at present want to work out such plans, 9% are already working out plans and 21% intend to do it

    Shimada, Takae; Kawasaki, Norihiro; Ueda, Yuzuru; Sugihara, Hiroyuki; Kurokawa, Kosuke

    This paper aims to clarify the battery capacity required by a residential area with densely grid-connected photovoltaic (PV) systems. This paper proposes a planning method of tomorrow's grid-connection power from/to the external electric power system by using demand power forecasting and insolation forecasting for PV power predictions, and defines a operation method of the electricity storage device to control the grid-connection power as planned. A residential area consisting of 389 houses consuming 2390 MWh/year of electricity with 2390kW PV systems is simulated based on measured data and actual forecasts. The simulation results show that 8.3MWh of battery capacity is required in the conditions of half-hour planning and 1% or less of planning error ratio and PV output limiting loss ratio. The results also show that existing technologies of forecasting reduce required battery capacity to 49%, and increase the allowable installing PV amount to 210%.

Examples of coverage under the green power insurance proposal are discussed, and the funding and implementation of the scheme, and the effect of the insurance are considered.

  5. An Improved Harmony Search Algorithm for Power Distribution Network Planning

    Directory of Open Access Journals (Sweden)

    Wei Sun

    2015-01-01

    Full Text Available Distribution network planning because of involving many variables and constraints is a multiobjective, discrete, nonlinear, and large-scale optimization problem. Harmony search (HS algorithm is a metaheuristic algorithm inspired by the improvisation process of music players. HS algorithm has several impressive advantages, such as easy implementation, less adjustable parameters, and quick convergence. But HS algorithm still has some defects such as premature convergence and slow convergence speed. According to the defects of the standard algorithm and characteristics of distribution network planning, an improved harmony search (IHS algorithm is proposed in this paper. We set up a mathematical model of distribution network structure planning, whose optimal objective function is to get the minimum annual cost and constraint conditions are overload and radial network. IHS algorithm is applied to solve the complex optimization mathematical model. The empirical results strongly indicate that IHS algorithm can effectively provide better results for solving the distribution network planning problem compared to other optimization algorithms.

    Concentrating solar power (CSP) technologies continue to mature and are being deployed worldwide. Power towers will likely play an essential role in the future development of CSP due to their potential to provide dispatchable solar electricity at a low cost. This Power Tower Technology Roadmap has been developed by the U.S. Department of Energy (DOE) to describe the current technology, the improvement opportunities that exist for the technology, and the specific activities needed to reach the DOE programmatic target of providing competitively-priced electricity in the intermediate and baseload power markets by 2020. As a first step in developing this roadmap, a Power Tower Roadmap Workshop that included the tower industry, national laboratories, and DOE was held in March 2010. A number of technology improvement opportunities (TIOs) were identified at this workshop and separated into four categories associated with power tower subsystems: solar collector field, solar receiver, thermal energy storage, and power block/balance of plant. In this roadmap, the TIOs associated with power tower technologies are identified along with their respective impacts on the cost of delivered electricity. In addition, development timelines and estimated budgets to achieve cost reduction goals are presented. The roadmap does not present a single path for achieving these goals, but rather provides a process for evaluating a set of options from which DOE and industry can select to accelerate power tower R&D, cost reductions, and commercial deployment.

    This research evaluates the importance and effectiveness of Environmental Impact Assessment (EIA) within wind farm planning debates, drawing on insights from case studies in Scotland. Despite general public support for renewable energy on the grounds that it is needed to tackle climate change and implement sustainable development, many proposed wind farms encounter significant resistance. The importance of planning issues and (EIA) processes has arguably been overlooked within recent wind farm social acceptability discourse. Through semi-structured interviews with key stakeholders and textual analysis of EIA documents, the characteristics of EIA are assessed in terms of its perceived purpose and performance. The data show that whilst respondents perceive EIA to be important, they express concerns about bias and about the inability of EIA to address climate change and wind farm decommissioning issues adequately. Furthermore, the research identifies key issues which impede the effectiveness of EIA, and reveals differences between theoretical and practical framings of EIA. The paper questions the assumption that EIA is a universally applicable tool, and argues that its effectiveness should be analysed in the context of specific development sectors. The article concludes by reviewing whether the recently amended EIA Directive (2014/52/EU) could resolve identified problems within national EIA practice. - Highlights: • Evaluation of EIA for onshore wind farm planning in Scotland. • EIA is important for multiple aspects of onshore wind farm planning. • Multiple substantive deficiencies of relevance to wind farm planning exist in EIA. • Further research into EIA effectiveness for specific development types is required. • Directive 2014/52/EU may improve EIA effectiveness within wind farm planning.

    Multicriteria decision support systems are applied in natural resource management in order to clarify the planning process for the stakeholders, to make all available information usable and all objectives manageable. Especially when the public is involved in planning, the decision support system should be easy to comprehend, transparent and fair. Social choice theory has recently been applied to group decision-making in natural resources management to accomplish these objectives. Although voting forms the basis of democracy, and is usually taken as a fair method, the influence of voters over the outcome may vary. It is also possible to vote strategically to improve the results from each stakeholder's point of view. This study examines the use of social choice theory in revealing stakeholders' preferences in participatory forest planning, and the influence of different voters on the outcome. The positional voting rules examined were approval voting and Borda count, but both rules were slightly modified for the purposes of this study. The third rule examined, cumulative rule, resembles utilitarian voting rules. The voting rules were tested in a real participatory forest planning situation in eastern Lapland, Finland. All voting rules resulted in a different joint order of importance of the criteria. Yet, the preference orders produced had also a lot in common and the criteria could be divided into three quite distinct groups according to their importance. The influence of individual voters varied between the voting rules, and in each case different voter was the most influential.

  20. Generation expansion planning in a competitive electric power industry

    Science.gov (United States)

    Chuang, Angela Shu-Woan

    This work investigates the application of non-cooperative game theory to generation expansion planning (GEP) in a competitive electricity industry. We identify fundamental ways competition changes the nature of GEP, review different models of oligopoly behavior, and argue that assumptions of the Cournot model are compatible with GEP. Applying Cournot theory of oligopoly behavior, we formulate a GEP model that may characterize expansion in the new competitive regime, particularly in pool-dominated generation supply industries. Our formulation incorporates multiple markets and is patterned after the basic design of the California ISO/PX system. Applying the model, we conduct numerical experiments on a test system, and analyze generation investment and market participation decisions of different candidate expansion units that vary in costs and forced outage rates. Simulations are performed under different scenarios of competition. In particular, we observe higher probabilistic measures of reliability from Cournot expansion compared to the expansion plan of a monopoly with an equivalent minimum reserve margin requirement. We prove several results for a subclass of problems encompassed by our formulation. In particular, we prove that under certain conditions Cournot competition leads to greater total capacity expansion than a situation in which generators collude in a cartel. We also show that industry output after introduction of new technology is no less than monopoly output. So a monopoly may lack sufficient incentive to introduce new technologies. Finally, we discuss the association between capacity payments and the issue of pricing reliability. And we derive a formula for computing ideal capacity payment rates by extending the Value of Service Reliability technique.

    2016-12-01

    Full Text Available Since renewable energy resource is universally accepted as a promising method to solve the global energy problem, optimal planning and utilization of various distributed generators (DG and energy storage (ES devices deserve special concern. ES devices possess various characteristics in power density, energy density, response speed (switching speed and lifetime. Besides, as different load types have various requirements on power supply reliability according to their importance, coordinated planning with consideration of reasonable matching between power source and load can efficiently improve power supply reliability and economic efficiency via a customized power supply and compensation strategy. This paper focuses on optimization of power source capacity in microgrid and a coordinated planning strategy is proposed with integrated consideration of characteristics of DG, ES and load. An index named additional compensation ratio (ACR for balancing economic efficiency and reliability is proposed and considered in the strategy. The objective function which aims to minimize life cycle cost (LCC is established considering economic efficiency, reliability and environmental conservation. The proposed planning strategy and optimizing model is calculated and verified through case study of an autonomy microgrid.

  5. Multiobjective Transmission Network Planning considering the Uncertainty and Correlation of Wind Power

    Directory of Open Access Journals (Sweden)

    Yuan Hu

    2014-01-01

    Full Text Available In order to consider the uncertainty and correlation of wind power in multiobjective transmission network expansion planning (TNEP, this paper presents an extended point-estimation method to calculate the probabilistic power flow, based on which the correlative power outputs of wind farm are sampled and the uncertain multiobjective transmission network planning model is transformed into a solvable deterministic model. A modified epsilon multiobjective evolutionary algorithm is used to solve the above model and a well-distributed Pareto front is achieved, and then the final planning scheme can be obtained from the set of nondominated solutions by a fuzzy satisfied method. The proposed method only needs the first four statistical moments and correlation coefficients of the output power of wind farms as input information; the modeling of wind power is more precise by considering the correlation between wind farms, and it can be easily combined with the multiobjective transmission network planning model. Besides, as the self-adaptive probabilities of crossover and mutation are adopted, the global search capabilities of the proposed algorithm can be significantly improved while the probability of being stuck in the local optimum is effectively reduced. The accuracy and efficiency of the proposed method are validated by IEEE 24 as well as a real system.

    Full Text Available The Nigerian Gas Master-Plan, Investment Opportunities, Challenges, Issues Affecting Power Sector: an Analysis. The objective of this article is to contribute towards understanding of the Nigerian Gas Master Plan (NGMP/Plan and its bifurcations with key socio-economic development factors. I applied the method of discourse to bring to being some points that have hitherto been unknown about the Master-plan and its inter-relationships and bifurcations. Elaborated here are the spectacular gains that have accrued to the Latin American country, Trinidad and Tobago, from its recent development of natural gas resources. This was considered suitable and significant here for highlighting that if such spectacular achievements could be realized from Trinidad and Tobago’s relatively smaller gas deposit (15.3 tcf, probable reserves (8.4 tcf, possible reserves (6.2 tcf would be by far greater considering Nigeria’s larger natural gas reserves (184 tcf wealth as earlier stated. I show that the Plan is well designed relevant to addressing Nigeria’s current development needs generally. It presents potentials for stimulating Nigeria’s economic growth by harnessing the country’s abundant natural gas reserves. The Plan enumerates/ elaborates huge investment opportunities. Some challenges likely to be faced in the implementation/management of the Plan are already being surmounted as recent reports show that some of its key investments have been realized and the required infrastructure are being provided. Regarding the issues in the Master-plan that are likely to affect and are affecting Nigeria’s power sector development, I reckon that they are mostly positive factors due to the way the plan promises to stimulate electricity generation in our country.

    Power generation expansion planning needs to deal with future uncertainties carefully, given that the invested generation assets will be in operation for a long time. Many stochastic programming models have been proposed to tackle this challenge. However, most previous works assume predetermined...... future uncertainties (i.e., fixed random outcomes with given probabilities). In several recent studies of generation assets’ planning (e.g., thermal versus renewable), new findings show that the investment decisions could affect the future uncertainties as well.

    The advanced metering infrastructure (AMI) is an architecture for two-way communication between electric, gas and water meters and city utilities. The AMI network is a wireless sensor network that provides communication for metering devices in the neighborhood area of the smart grid. Recently, the applicability of a routing protocol for low-power and lossy networks (RPL) has been considered in AMI networks. Some studies in the literature have pointed out problems with RPL, including sub-optimal path selection and instability. In this paper, we defend the viewpoint that careful planning of the transmission power in wireless RPL networks can significantly reduce the pointed problems. This paper presents a method for planning the transmission power in order to assure that, after convergence, the size of the parent set of the RPL nodes is as close as possible to a predefined size. Another important feature is that all nodes in the parent set offer connectivity through links of similar quality.

    Demand response is becoming a promising field of study in operation and planning of restructured power systems. More attention has recently been paid to demand response programs. Customers can contribute to the operation of power sys-tems by deployment demand response. The growth of customers’ participation in such programs may affect the planning of power systems. Therefore, it seems necessary to consider the effects of demand response in planning approaches. In this paper, the impact of demand responsiveness on decision making in generation expansion planning is modeled. Avoidance or deferment in installation of new generating units is comprehensively investigated and evaluated by introducing a new simple index. The effects of demand responsiveness are studied from the points of view of both customers and generation companies. The pro-posed model has been applied to a modified IEEE 30-bus system and the results of the study are discussed. Simulation results show that reducing just 3%of the customers’ demand (due to price elasticity) may result in a benefit of about 10%for customers in the long term.

    1980-11-30

    Florida Power Corporation (FPC) conducted an evaluation of the possible integration of OTEC into the FPC system. Existing system planning procedures, assumptions, and corporate financial criteria for planning new generating capacity were used without modification. A baseline configuration for an OTEC plant was developed for review with standard planning procedures. The OTEC plant characteristics and costs were incorporated in considerable detail. These basic inputs were examined using the FPC system planning methods. It was found that with the initial set of conditions, OTEC would not be economically viable. Using the same system planning procedures, a number of adjustments were made to the key study assumptions. It was found that two considerations dominate the analysis; the assumed rate of fuel cost escalation, and the projected capital cost of the OTEC plant. The analysis produced a parametric curve: on one hand, if fuel costs were to escalate at a rate greater than assumed (12% vs the assumed 5% for coal), and if no change were made to the OTEC input assumptions, the basic economic competitive criteria would be equivalent to the principal alternative, coal fueled plants. Conversely, if the projected cost of the OTEC plant were to be reduced from the assumed $2256/kW to $1450/kW, the economic competitiveness criterion would be satisfied. After corporate financial analysis, it was found that even if the cost competitive criterion were to be reached, the plan including OTEC could not be financed by Florida Power Corporation. Since, under the existing set of conditions for financing new plant capital requirements, FPC could not construct an OTEC plant, some other means of ownership would be necessary to integrate OTEC into the FPC system. An alternative such as a third party owning the plant and selling power to FPC, might prove attractive. (WHK)

    Following the Fukushima accident, the safety features of Nuclear Power Plants (NPP) are being re-examined worldwide including India to demonstrate capabilities to cope with severe accidents. In order to restore public confidence and support for nuclear power, it is felt necessary to design future NPPs with near zero impact outside the plant boundary and thus enabling elimination of emergency planning in public domain. Authors have identified a set of safety features which are needed to be incorporated in advanced reactors to achieve this goal. These features enabling prevention, termination, mitigation and containment of radioactivity for beyond design basis accidents arising from extreme natural events are essential for achieving the goal of elimination of emergency planning in public domain. Inherent safety characteristics, passive and engineered safety features to achieve these functions are discussed in this paper. Present trends and future developments in this direction are also described briefly.

    The aim of this paper is to apply a fuzzy possibilistic model to the power generation planning that includes environmental criteria. Since it is not always meaningful to relate uncertainty to frequency, the proposed approach analyzes the imprecision and ambiguity into the decision making, especially when the system involves human subjectivity. This paper highlights the subjacent differences between fuzzy and possibilistic entities. Additionally, it illustrates the use of fuzzy sets theory and possibility theory for modeling flexibility, and nonprobablistic uncertainty, respectively. The necessity of a new direction for the environmental problem in a power system is outlined, an approach that attempts a greater integral quality of planning instead of searching for a simple optimal solution. This process must be consistent with a wider and more suitable interpretation about both the problem as such and the concept of solution in uncertain situations. (author)

To achieve this objective, American Ideas and Designs, Inc., d/b/a Greening America (hereinafter referred to as Recipient) has assisted FEMP in developing a comprehensive energy efficiency technology transfer program plan (hereinafter referred to as the outreach plan). A key component of the outreach plan involved the development and launch of a technology transfer campaign entitled ``You Have the Power.`` The outreach plan and the ``You Have the Power`` campaign emphasized the ability of individual Federal employees, Federal agencies, and stakeholder organizations to easily access FEMP`s energy efficiency tools and resources through a set of integrated interagency delivery programs.

  3. Switch: a planning tool for power systems with large shares of intermittent renewable energy.

    Wind and solar power are highly variable, so it is it unclear how large a role they can play in future power systems. This work introduces a new open-source electricity planning model--Switch--that identifies the least-cost strategy for using renewable and conventional generators and transmission in a large power system over a multidecade period. Switch includes an unprecedented amount of spatial and temporal detail, making it possible to address a new type of question about the optimal design and operation of power systems with large amounts of renewable power. A case study of California for 2012-2027 finds that there is no maximum possible penetration of wind and solar power--these resources could potentially be used to reduce emissions 90% or more below 1990 levels without reducing reliability or severely raising the cost of electricity. This work also finds that policies that encourage customers to shift electricity demand to times when renewable power is most abundant (e.g., well-timed charging of electric vehicles) could make it possible to achieve radical emission reductions at moderate costs.

  5. Integrating planning and design optimization for thermal power generation in developing economies: Designs for Vietnam

    Science.gov (United States)

    Pham, John Dinh Chuong

    In the twenty first century, global warming and climate change have become environmental issues worldwide. There is a need to reduce greenhouse gas emissions from thermal power plants through improved efficiency. This need is shared by both developed and developing countries. It is particularly important in rapidly developing economies (for example, Vietnam, South Korea, and China) where there is very significant need to increase generation capacity. This thesis addresses improving thermal power plant efficiency through an improved planning process that emphasizes integrated design. With the integration of planning and design considerations of key components in thermal electrical generation, along with the selection of appropriate up-to-date technologies, greater efficiency and reduction of emissions could be achieved. The major barriers to the integration of overall power plant optimization are the practice of individual island tendering packages, and the lack of coordinating efforts between major original equipment manufacturers (OEM). This thesis assesses both operational and design aspects of thermal power plants to identify opportunities for energy saving and the associated reduction of CO2 emissions. To demonstrate the potential of the integrated planning design approach, three advanced thermal power plants, using anthracite coal, oil and gas as their respective fuel, were developed as a case study. The three plant formulations and simulations were performed with the cooperation of several leading companies in the power industry including Babcock & Wilcox, Siemens KWU, Siemens-Westinghouse Power Corporation, Hitachi, Alstom Air Preheater, TLT-Covent, and ABB Flakt. The first plant is a conventional W-Flame anthracite coal-fired unit for base load operation. The second is a supercritical oil-fired plant with advanced steam condition, for two shifting and cycling operations. The third plant is a gas-fired combined cycle unit employing a modern steam-cooled gas

    Power plants constitute roughly 40% of carbon dioxide (CO2) emissions in the United States. Climate change science, air pollution regulation, and potential carbon trading policies rely on accurate, unbiased quantification of these large point sources. Two US federal agencies—the Department of Energy and the Environmental Protection Agency—tabulate the emissions from US power plants using two different methodological approaches. We have analyzed those two data sets and have found that when averaged over all US facilities, the median percentage difference is less than 3%. However, this small difference masks large, non-Gaussian, positive and negative differences at individual facilities. For example, over the 2001-2009 time period, nearly one-half of the facilities have monthly emission differences that exceed roughly ±6% and one-fifth exceed roughly ±13%. It is currently not possible to assess whether one, or both, of the datasets examined here are responsible for the emissions difference. Differences this large at the individual facility level raise concerns regarding the operationalization of policy within the United States such as the recently announced Clean Power Plan. This policy relies on the achievement of state-level CO2 emission rate targets. When examined at the state-level we find that one-third of the states have differences that exceed 10% of their assigned reduction amount. Such levels of uncertainty raise concerns about the ability of individual states to accurately quantify emission rates in order to meet the regulatory targets.

    Ringhals has been a model for this study, but the purpose has been to make the report applicable at all nuclear power plants in Sweden. The work has been done in close co-operation with the Swedish nuclear power plants and Rescue Services in the nuclear power municipalities Oesthammar, Oskarshamn, and Varberg. The internal fire brigade at the nuclear power plants has also been involved. A document will also be published as a further guidance at efforts of the type fires, which are mentioned in the enclosed document. After a fire in a switchgear room in 2005 the need of making the existing effort planning more effective at nuclear power plants was observed. The idea with the planning is to plan the effort in order to give the operational and emergency staff a good and actual support to come to a decision and to start the mission without delay. The risk information is showed by planning layouts, symbols and drawings as basis, give risk information and effort information. The effort information shows outer arrangements, manual action points, fire installations, passive fire safety etc. The risk information is shown by risk symbols. Their purpose is to give a fast overview of the existing risks. Reactor safety effects is the ruling influence if an effort has to be done in order to secure safety for a third person. In order to make an effort in an area personal risks for rescue staff, such as electricity risks, radiological risks, chemicals and gas bottles with compressed gases, has to be eliminated. For complicated missions detailed instructions are needed in order to handle specific risks. In a group discussion different people with pertinent knowledge has to value which problematic efforts need detailed instruction. Missions that have to be analyzed in a work group as above are: fire may affect the reactor safety, fire that may threaten the structural integrity, chemical discharge with big consequence on environment/third person and handling of gas system (compressed

    The use of digital technologies in monitoring and control systems of nuclear power plants and their connectivity requirements, originate cybersecurity difficulties that should be addressed in a cybersecurity plan. This plan should guide the policies and procedures followed during the design maintenance and operation of the systems inside a nuclear power plant. It also should refer to adequate tools able to reach the established cybersecurity requirements. The combination of Datadiodes and tools for publishing video (like tVGA2web), permit an isolation and remote maintenance in a 100% safety way and their use should be disseminated. In the paper other type of tools useful for nuclear power plants are also mentioned.

    Since the early 1960’s the Department of Energy (DOE) and its predecessor agencies have provided radioisotope power systems (RPS) to NASA as an enabling technology for deep space and various planetary missions. They provide reliable power in situations where solar and/or battery power sources are either untenable or would place an undue mass burden on the mission. In the modern era of the past twenty years there has been no time that multiple missions have been considered for launching from Kennedy Space Center (KSC) during the same year. The closest proximity of missions that involved radioisotope power systems would be that of Galileo (October 1989) and Ulysses (October 1990). The closest that involved radioisotope heater units would be the small rovers Spirit and Opportunity (May and July 2003) used in the Mars Exploration Rovers (MER) mission. It can be argued that the rovers sent to Mars in 2003 were essentially a special case since they staged in the same facility and used a pair of small launch vehicles (Delta II). This paper examines constraints on the frequency of use of radioisotope power systems with regard to launching them from Kennedy Space Center using currently available launch vehicles. This knowledge may be useful as NASA plans for its future deep space or planetary missions where radioisotope power systems are used as an enabling technology. Previous descriptions have focused on single mission chronologies and not analyzed the timelines with an emphasis on multiple missions.

    2000-07-20

    Pulsed power science and engineering activities at Sandia National Laboratories grew out of a programmatic need for intense radiation sources to advance capabilities in radiographic imaging and to create environments for testing and certifying the hardness of components and systems to radiation in hostile environments. By the early 1970s, scientists in laboratories around the world began utilizing pulsed power drivers with very short (10s of nanoseconds) pulse lengths for Inertial Confinement Fusion (ICF) experiments. In the United States, Defense Programs within the Department of Energy has sponsored this research. Recent progress in pulsed power, specifically fast-pulsed-power-driven z pinches, in creating temperatures relevant to ICF has been remarkable. Worldwide developments in pulsed power technologies and increased applications in both defense and industry are contrasted with ever increasing stress on research and development tiding. The current environment has prompted us at Sandia to evaluate our role in the continued development of pulsed power science and to consider options for the future. This presentation will highlight our recent progress and provide an overview of our plans as we begin the new millennium.

  12. The Optimization Model for Interregional Power System Planning considering Carbon Emissions Trading and Renewable Energy Quota Mechanism

    2016-01-01

    Full Text Available In China, the rapid construction of ultra-high-voltage (UHV transmission lines promotes interregional resource optimizing configuration and interregional power system planning. This paper analyzes external environment of interregional power system planning from geographical, technical, and policy environments. Then, the paper takes the minimum system investment cost as the optimization objective and constructs the optimization model of interregional power system planning considering carbon emissions trading (CET and renewable energy quota mechanism (REQ. Finally, this paper sets base scenario, carbon emissions trading scenario, renewable energy quota mechanism scenario, and comprehensive scenario for case simulation. The results show that interregional power system planning could connect power grids in different regions, enlarge wind power consumption space, and relieve the inconformity problem between power resource and load demand. CET and REQ can increase the installed proportion of clean energy and reduce carbon dioxide emissions, but the cost of transmission lines construction and system reserve will increase correspondingly. The optimization effect of REQ on power system planning is better than CET. When they are both introduced, the power structure will reach the best, carbon dioxide emissions will achieve the minimum, and comprehensive benefits will become more balanced.

    2006-07-01

    A country utilising nuclear energy is presumed to possess a sufficient infrastructure to cover the education and research in this field, besides the operating organisations of the plants and a regulatory body. The starting point of public nuclear safety research programmes is that they provide the necessary conditions for retaining the knowledge needed for ensuring the continuance of safe and economic use of nuclear power, for development of new know-how and for participation in international cooperation. In fact, the Finnish organisations engaged in research in this sector have been an important resource which the various ministries, the Radiation and Nuclear Safety Authority (STUK) and the power companies have had at their disposal. Ministry of Trade and Industry appointed a group to write the Framework Plan of the new programme. This report contains a proposal for the general outline of the programme, preliminarily entitled as SAFIR2010 (SAfety of Nuclear Power Plants - Finnish National Research Programme). The plan has been made for the period 2007-2010, but it is based on safety challenges identified for a longer time span as well. Olkiluoto 3, the new nuclear power plant unit under construction has also been taken into account in the plan. The safety challenges set by the existing plants and the new plant unit, as well as the ensuing research needs do, however, converge to a great extent. The research programme is strongly based on the Chapter 7a of the Finnish Nuclear Energy Act. The construction of the new power plant unit will increase the need for experts in the field in Finland. At the same time, the retirement of the existing experts is continuing. These factors together will call for more education and training, in which active research activities play a key role. This situation also makes long-term safety research face a great challenge. The Framework Plan aims to define the important research needs related to the safety challenges. The research into

    The Institute of Seismology of University of Helsinki is building a new local seismic network, called OBF network, around planned nuclear power plant in Northern Ostrobothnia, Finland. The network will consist of nine new stations and one existing station. The network should be dense enough to provide azimuthal coverage better than 180° and automatic detection capability down to ML -0.1 within a radius of 25 km from the site.The network construction work began in 2012 and the first four stations started operation at the end of May 2013. We applied an automatic seismic signal detection and event location system to a network of 13 stations consisting of the four new stations and the nearest stations of Finnish and Swedish national seismic networks. Between the end of May and December 2013 the network detected 214 events inside the predefined area of 50 km radius surrounding the planned nuclear power plant site. Of those detections, 120 were identified as spurious events. A total of 74 events were associated with known quarries and mining areas. The average location error, calculated as a difference between the announced location from environment authorities and companies and the automatic location, was 2.9 km. During the same time period eight earthquakes between magnitude range 0.1-1.0 occurred within the area. Of these seven could be automatically detected. The results from the phase 1 stations of the OBF network indicates that the planned network can achieve its goals.

Therefore, it is urgent to carry out power grid construction. From the beginning of 2011 till now, China has made a huge investment to build state-level smart power grid, and new aluminum alloy transmission conductors or smart power grid will play an active role in the construction boom.

  16. Regional power systems planning: a state of the art assessment. Final report

    Energy Technology Data Exchange (ETDEWEB)

    1980-10-01

    The purpose of this report was to define regional power systems planning problems, the tools available and their shortcomings, and to document all of the above in a concise readable form. The approach consisted of a survey and literature search. The survey determined the tools being used by utilities, the tools they had rejected, and the tools they planned to try out. The literature search was conducted for the purpose of documenting the tools available, and performing a comparative analysis of these tools. The project included a mix of utility, university, and consulting organizations. Several organizations were consulted in the selection of the participants. A non-profit organization, The University of Oklahoma, was selected to manage the project. The results were reviewed in a series of four one day meetings by known authorities in each field. This report consists of the results of this project. Perhaps its major finding is that several aspects of the regional planning problem are not well defined, the roles of the various participants in regional planning is not clear, and certainly research is needed for the development of new methodology.

    1998-12-01

    The state-of-the-art restructuring of power industries is changing the fundamental nature of retail electricity business. As a result, the so-called Integrated Resource Planning (IRP) strategies implemented on electric utilities are also undergoing modifications. Such modifications evolve from the imminent considerations to minimize the revenue requirements and maximize electrical system reliability vis-a-vis capacity-additions (viewed as potential investments). IRP modifications also provide service-design bases to meet the customer needs towards profitability. The purpose of this research as deliberated in this dissertation is to propose procedures for optimal IRP intended to expand generation facilities of a power system over a stretched period of time. Relevant topics addressed in this research towards IRP optimization are as follows: (1) Historical prospective and evolutionary aspects of power system production-costing models and optimization techniques; (2) A survey of major U.S. electric utilities adopting IRP under changing socioeconomic environment; (3) A new technique designated as the Segmentation Method for production-costing via IRP optimization; (4) Construction of a fuzzy relational database of a typical electric power utility system for IRP purposes; (5) A genetic algorithm based approach for IRP optimization using the fuzzy relational database.

    According to government regulations, the emergency planning zone (EPZ) of a nuclear power plant (NPP) must be designated before operation and reevaluated every 5 years. Corresponding emergency response planning (ERP) has to be made in advance to guarantee that all necessary resources are available under accidental releases of radioisotope. In this study, the EPZ for each of the three operating NPPs, Chinshan, Kuosheng, and Maanshan, in Taiwan was reevaluated using the MELCOR Accident Consequence Code System 2 (MACCS2) developed by Sandia National Laboratory. Meteorological data around the nuclear power plant were collected during 2003. The source term data including inventory, sensible heat content, and timing duration, were based on previous PRA information of each plant. The effective dose equivalent and thyroid dose together with the related individual risk and societal risk were calculated. By comparing the results to the protective action guide and related safety criteria, 1.5, 1.5, and 4.5km were estimated for Chinshan, Kuosheng, and Maanshan NPPs, respectively. We suggest that a radius of 5.0km is a reasonably conservative value of EPZ for each of the three operating NPPs in Taiwan.

    A joint National Aeronautics and Space Administration (NASA) and Department of Energy (DOE) team is developing concepts and technologies for affordable nuclear Fission Power Systems (FPSs) to support future exploration missions. A key deliverable is the Technology Demonstration Unit (TDU). The TDU will assemble the major elements of a notional FPS with a non-nuclear reactor simulator (Rx Sim) and demonstrate system-level performance in thermal vacuum. The Rx Sim includes an electrical resistance heat source and a liquid metal heat transport loop that simulates the reactor thermal interface and expected dynamic response. A power conversion unit (PCU) generates electric power utilizing the liquid metal heat source and rejects waste heat to a heat rejection system (HRS). The HRS includes a pumped water heat removal loop coupled to radiator panels suspended in the thermal-vacuum facility. The basic test plan is to subject the system to realistic operating conditions and gather data to evaluate performance sensitivity, control stability, and response characteristics. Upon completion of the testing, the technology is expected to satisfy the requirements for Technology Readiness Level 6 (System Demonstration in an Operational and Relevant Environment) based on the use of high-fidelity hardware and prototypic software tested under realistic conditions and correlated with analytical predictions.

    Governments around the world try to stimulate the development and use of renewable energy technologies, like wind energy. While wind turbines are increasingly being implemented, however, a lack of social acceptance at the local level remains an important challenge for developers of wind power plants. This article aims to explore the relative importance of social and institutional conditions and their interdependencies in the operational process of planning wind power schemes. The article not only focuses on how negative local social conditions can frustrate public policy (cf. NIMBY syndrome), but also on how positive local social conditions can compensate for a negative public policy framework. We analyzed the cases of implementing wind power of two actors (the regional energy distributor and small private investors) in the municipality of Zeewolde, the Netherlands. Both cases illustrate that the formal institutional framework (formal rules, procedures and instruments) is neutral in a certain sense. Social conditions - management styles, interests and informal contacts - put meaning in this framework. The way stakeholders deal with the prevailing institutional structure clarifies social acceptance and therewith implementation. (author)

    Production planning in Combined Heat and Power (CHP) systems is considered. The focus is on development and use of mathematical models and methods. Different aspects on production planning are discussed, including weather and load predictions. Questions relevant on the different planning horizons are illuminated. The main purpose with short-term (one week) planning is to decide when to start and stop the production units, and to decide how to use the heat storage. The main conclusion from the outline of pros and cons of commercial planning software are that several are using Mixed Integer Programming (MIP). In that sense they are similar. Building a production planning model means that the planning problem is formulated as a mathematical optimization problem. The accuracy of the input data determines the practical detail level of the model. Two alternatives to the methods used in today's commercial programs are proposed: stochastic optimization and simulator-based optimization. The basic concepts of mathematical optimization are outlined. A simulator-based model for short-term planning is developed. The purpose is to minimize the production costs, depending on the heat demand in the district heating system, prices of electricity and fuels, emission taxes and fees, etc. The problem is simplified by not including any time-linking conditions. The process model is developed in IPSEpro, a heat and mass-balance software from SimTech Simulation Technology. TOMLAB, an optimization toolbox in MATLAB, is used as optimizer. Three different solvers are applied: glcFast, glcCluster and SNOPT. The link between TOMLAB and IPSEpro is accomplished using the Microsoft COM technology. MATLAB is the automation client and contains the control of IPSEpro and TOMLAB. The simulator-based model is applied to the CHP plant in Eskilstuna. Two days are chosen and analyzed. The optimized production is compared to the measured. A sensitivity analysis on how variations in outdoor

Using state space discretization, the Convex Hull algorithm is used for constructing a series of hyperplanes that composes a convex set. These planes represent a piecewise linear approximation for the expected cost-to-go functions. The mean operational costs for using the proposed methodology were compared with those from the deterministic dual dynamic problem in a case study, considering a single inflow scenario. This sensitivity analysis shows the convergence of both methods and is used to determine the minimum discretization level. Additionally, the applicability of the proposed methodology for two hydroplants in a cascade is demonstrated. With proper adaptations, this work can be extended to a complete hydrothermal system.

    One of the means of evaluating a new technology is to have it considered by a utility company, run through the system planning, and thus scrutinized by a potential user of the new technology in a manner directly drawn from the user's methods of decision making on new capacity additions. By having Florida Power Corporation (FPC), a company with real potential for the future use of ocean thermal energy conversion (OTEC), exercise its system planning methods to consider this possible source of future generating capacity, a number of highly useful results will be obtained. The overall study of the application of system planning to OTEC is being carried out in four tasks. This report covers task-1 which provides a description of the existing system and the planning process of Florida Power Corporation. (WHK)

  13. Spatiotemporal dynamics of prairie wetland networks: power-law scaling and implications for conservation planning.

    Wright, Christopher K

    2010-07-01

    Although habitat networks show promise for conservation planning at regional scales, their spatiotemporal dynamics have not been well studied, especially in climate-sensitive landscapes. Here I use satellite remote sensing to compile wetland habitat networks from the Prairie Pothole Region (PPR) of North America. An ensemble of networks assembled across a hydrologic gradient from deluge to drought and a range of representative dispersal distances exhibits power-law scaling of important topological parameters. Prairie wetland networks are "meso-worlds" with mean topological distance increasing faster with network size than small-world networks, but slower than a regular lattice (or "large world"). This scaling implies rapid dispersal through wetland networks without some of the risks associated with "small worlds" (e.g., extremely rapid propagation of disease or disturbance). Retrospective analysis of wetland networks establishes a climatic envelope for landscape connectivity in the PPR, where I show that a changing climate might severely impact metapopulation viability and restrict long-distance dispersal and range shifts. More generally, this study demonstrates an efficient approach to conservation planning at a level of abstraction addressing key drivers of the global biodiversity crisis: habitat fragmentation and climatic change.

    Full Text Available The large number of decision variables of long-term planning problem for improving the distribution system causes lots of complexities. The optimum allocation of Distributed Generation (DG sources and determining their capacity in the deregulated electric market is a key way for capacity expansion of the distribution firm. In this study, a new approach is presented to determination the optimum location and capacity of DG sources in the deregulated electric market through the net present value analysis using an optimization model. This model aims to minimize the investment cost of the distribution firm, utility cost and the losses cost considering the anticipated load peak value. Considering the power market price anticipation to be indefinite, the proposed method is based on laying out the genetic algorithm and a fuzzy model to the power market price and the capacity expansion design of the distribution system during different time intervals is proposed along with two static and semi-dynamic methods. The efficiency of the proposed approach is well shown applying it to a sample network.

    2016-12-01

    Full Text Available Micro gas turbines (MGTs are regarded as combined heat and power (CHP units which offer high fuel utilization and low emissions. They are applied in decentralized energy generation. To facilitate the planning process of energy systems, namely in the context of the increasing application of optimization techniques, there is a need for easy-to-parametrize component models with sufficient accuracy which allow a fast computation. In this paper, a model is proposed where the non-linear part load characteristics of the MGT are linearized by means of physical insight of the working principles of turbomachinery. Further, it is shown that the model can be parametrized by the data usually available in spec sheets. With this model a uniform description of MGTs from several manufacturers covering an electrical power range from 30 k W to 333 k W can be obtained. The MGT model was implemented by means of Modelica/Dymola. The resulting MGT system model, comprising further heat exchangers and hydraulic components, was validated using the experimental data of a 65 k W MGT from a trigeneration energy system.

To solve this problem, a reactive power optimization software module for the urban HV&MV distribution network was developed in the paper, which is based on the actual business characteristics and by applying multilevel problem decomposition and layered architecture design idea. It includes three sub-modules: the optimal calculation sub-module, the original data management sub-module and the result data management sub-module. This module covers the planning functions of reactive power optimization for the present network, reactive power optimization for the target years, and the multi-stage reactive power optimization. In the actual application, the module can be embedded into the power network planning decision support system (named CNP) and serves as a subsystem of the overall system, while it also can be used as a stand-alone software system, which has wide applicability. Practical application in real power network shows that its functions can assist reactive power planning of city power network and improve the efficiency of urban power network planning.

  18. Implications of renewable energy technologies in the Bangladesh power sector. Long-term planning strategies

    2010-10-04

    Bangladesh is facing daunting energy challenges: Security concerns over growing fuel imports, limited domestic energy resources for power generation, and projected demands for electricity that will exceed domestic supply capabilities within a few years. By acknowledging the potential of renewable energy resources, the country could possibly meet its unprecedented energy demand, thus increasing electricity accessibility for all and enhancing energy security through their advancement. The integration of renewable energy technologies in the power sector through national energy planning would, therefore, be a step in the right direction, not only for sustainable development of the country but also as part of Bangladesh's responsibility toward the global common task of environmental protection. This study estimates the potential of renewable energy sources for power generation in Bangladesh from the viewpoint of different promising available technologies. Future long-term electricity demand in Bangladesh is projected based on three economic growth scenarios. The energy planning model LEAP is applied to forecast the energy requirements from 2005 to 2035. Different policy scenarios, e.g., accelerated renewable energy production, null coal import, CO2 emission reduction targets and carbon taxes in the power sector from 2005 to 2035 are explored. The analyses are based on a long-term energy system model of Bangladesh using the MARKAL model. Prospects for the power sector development of the country are identified, which ensure energy security and mitigate environmental impacts. The technical potential of grid-connected solar photovoltaic and wind energy are estimated at 50174 MW and 4614 MW, respectively. The potential of energy from biomass and small hydro power plants is estimated at 566 MW and 125 MW, respectively. Total electricity consumption was 18 TWh in 2005 and is projected to increase about 7 times to 132 TWh by 2035 in the low GDP growth scenario. In the

    The Draft Biological Opinion on Operation of the Federal Columbia River Power System calls for the development of 1- and 5-year implementation plans. These plans will provide the roadmap for planning and subsequent implementation of actions intended to meet specific performance standards (i.e., biological objectives) in a timely manner. To develop implementation plans the key tasks and sequences of steps must be determined. Those responsible for specific tasks must be identified and they must understand what they need to do. There must be assurances that the resources (human, physical, and fiscal) to complete the tasks are available. Motivation and incentive systems should be set up. Systems to coordinate efforts and guide activity must be devised and installed. An information management system must be designed to manage and analyze data and ensure that appropriate data are collected. This will aid managers in assessing whether individual activities or actions are tracking with stated goals and objectives. Training programs to improve managerial and worker capability in making and implementing plans should be designed. Managerial leadership to guide the efforts of all individuals in achieving the goals of the anadromous and resident fish recovery must be developed. It is the entire process of managing fish recovery in relationship to the Biological Opinion that will guide, coordinate, motivate, and control work and determine the effectiveness and efficiency of plan implementation.

    Combined Heat and Power (CHP) is an important option for states to consider in developing strategies to meet their emission targets under the US Environmental Protection Agency's Clean Power Plan. This Template is designed to highlight key issues that states should consider when evaluating whether CHP could be a meaningful component of their compliance plans. It demonstrates that CHP can be a valuable approach for reducing emissions and helping states achieve their targets. While the report does not endorse any particular approach for any state, and actual plans will vary dependent upon state-specific factors and determinations, it provides tools and resources that states can use to begin the process, and underscores the opportunity CHP represents for many states. . By producing both heat and electricity from a single fuel source, CHP offers significant energy savings and carbon emissions benefits over the separate generation of heat and power, with a typical unit producing electricity with half the emissions of conventional generation. These efficiency gains translate to economic savings and enhanced competitiveness for CHP hosts, and emissions reductions for the state, along with helping to lower electric bills; and creating jobs in the design, construction, installation and maintenance of equipment. In 2015, CHP represents 8 percent of electric capacity in the United States and provides 12 percent of total power generation. Projects already exist in all 50 states, but significant technical and economic potential remains. CHP offers a tested way for states to achieve their emission limits while advancing a host of ancillary benefits.

  1. Three essays on the effect of wind generation on power system planning and operations

    Science.gov (United States)

    Davis, Clay Duane

    While the benefits of wind generation are well known, some drawbacks are still being understood as wind power is integrated into the power grid at increasing levels. The primary difference between wind generation and other forms of generation is the intermittent, and somewhat unpredictable, aspect of this resource. The somewhat uncontrollable aspect of wind generation makes it important to consider the relationship between this resource and load, and also how the operation of other non-wind generation resources may be affected. The three essays that comprise this dissertation focus on these and other important issues related to wind generation; leading to an improved understanding of how to better plan for and utilize this resource. The first essay addresses the cost of increased levels of installed wind capacity from both a capacity planning and economic dispatch perspective to arrive at the total system cost of installing a unit of wind capacity. This total includes not only the cost of the wind turbine and associated infrastructure, but also the cost impact an additional unit of wind capacity has on the optimal mix and operation of other generating units in the electricity supply portfolio. The results of the model showed that for all wind expansion scenarios, wind capacity is not cost-effective regardless of the level of the wind production tax credit and carbon prices that were considered. Larger levels of installed wind capacity result in reduced variable cost, but this reduction is not able to offset increases in capital cost, as a unit of installed wind capacity does not result in an equal reduction in other non-wind capacity needs. The second essay develops a methodology to better handle unexpected short term fluctuations in wind generation within the existing power system. The methodology developed in this essay leads to lower expected costs by anticipating and planning for fluctuations in wind generation by focusing on key constraints in the system. The

    If a local anticyclone can be created by a certain way, strong wind may be created by a large pressure difference between the local anticyclone and surrounding atmosphere. This paper describes a plan of using this wind for wind power generation. When temperatures are the same at the top of a cylinder tube, temperature difference of 0.35 {degree}C between dry air and wet air is obtained every 100 m, which results in the density difference. Thus, air density difference is generated between inside and outside of a vertical cylinder tube. Cumulonimbus is wet and low temperature air in the high altitude. This natural phenomenon suggests the present idea. Within the Cumulonimbus, a large amount of water vapor rises at high speed, water and ice droplets are condensed and solidified on the way of rising, and surrounding air is cooled by the vaporization on the way of dropping, which results in the down current with high density. In the present idea, water vapor generated at the bottom is ascended without discharging into the surrounding atmosphere, is heat-exchanged with surrounding air at high altitude, is mixed with dry air to cool itself, and is descended in the vertical cylinder tube. 1 ref., 5 figs.

    2013-06-01

    Full Text Available In power generation expansion planning, electric utilities have encountered the major challenge of environmental awareness whilst being concerned with budgetary burdens. The approach for selecting generating technologies should depend on economic and environmental constraint as well as externalities. Thus, the multi-objective optimization becomes a more attractive approach. This paper presents a hybrid framework of multi-objective optimization and multi-criteria decision making to solve power generation expansion planning problems in Thailand. In this paper, CO2 emissions and external cost are modeled as a multi-objective optimization problem. Then the analytic hierarchy process is utilized to determine thecompromised solution. For carbon capture and storage technology, CO2 emissions can be mitigated by 74.7% from the least cost plan and leads to the reduction of the external cost of around 500 billion US dollars over the planning horizon. Results indicate that the proposed approach provides optimum cost-related CO2 mitigation plan as well as external cost.

    For the protection of the public health against nuclear accidents with major release of radioactive material, the Emergency Planning Zone(EPZ) has been designated for an area with a radius of 8{approx}10 km around nuclear power plants(NPPs) in Korea. However, since the current size of EPZ set in 1980's is based on simple assumptions about accident source terms, meteorological conditions, and conservative protective action guides(PAGs), 10 mSv to the whole body and 100 mSv to the thyroids, it is questionable that the current EPZ provides adequate protection against spectrum of accidents encompassing probable severe reactor accidents. The aim of this study is to establish a new methodology to determine the EPZ for NPPs in Korea by reflecting advances in the reactor risk assessment. An illustrative evaluation of EPZ sizes was carried out for the Uljin NPP units 3 and 4. Since the previous PAGs did not seem to warrant initiation of burdensome protective actions, the new PAGs were set to the level of preventing serious deterministic effects-early fatality was considered in this study-as recommended by the International Commission on Radiological Protection(ICRP). In addition, after the guidelines developed by the International Atomic Energy Agency(IAEA), EPZs were sub-divided into two categories: the Precautionary Action Zone(PAZ) and the Urgent Protective Action Planning Zone(UPZ). Six severe accident source term categories(STCs) resulted from the individual plant examination study for Uljin 3 and 4, for which the core damage frequency exceeded approximately 10{sup -6} per reactor year, were selected and corresponding environmental release source terms were adopted as accident source terms for EPZ determination. The MACCS2(MELCOR Accident Consequence Code System2) was used in calculation of radiological consequences. The radiological emergency plans and procedures for Uljin NPPs were referred for accident notification system and the planned protective actions. The

To understand the perception of NPP risks by the public in Taiwan and their attitudes regarding a planned fourth NPP after the Fukushima nuclear incident in 2011, a study was conducted in August 2011. A sample of 2819 individuals responded to the survey, with 66% perceiving that Taiwan's safety management of NPPs was inferior to Japan's, while 40% perceived a higher possibility of nuclear accidents like that in Japan. On average, a 'safe' distance of 94 km from an NPP was expected. 56% opposed the planned fourth NPP, with females (adjusted odd ratios (aOR) 2.03; 95% confidence interval (CI) 1.71-2.41), residence near the planned fourth NPP (aOR/CI 13.90/7.79-24.80), distrust of safety management (aOR/CI 1.98/1.45-2.69) and emergency planning (aOR/CI 1.89/1.49-2.40) as the main determinants. Others included those who expected larger safe distances from an NPP (trend test, p risks of living within 30 km of an NPP (aOR/CI 2.74/2.02-3.71), and projection of no electric shortage without NPPs (aOR/CI 1.93/1.50-2.49). Given that Taiwan's large population lives close to the existing NPPs and long-term concerns about the safety of these nuclear plants, the Fukushima incident in Japan likely augmented public risk perceptions on nuclear power in general and on the planned fourth NPP.

  1. Philippines. Church vs. state: Fidel Ramos and family planning face "Catholic Power".

    1994-08-24

    Catholic groups and individuals united in a public rally in Manila's Rizal Park to decry a "cultural dictatorship," which promotes abortion, homosexuality, lesbianism, sexual perversion, condoms, and artificial contraception. Government spokesmen responded that condoms and contraception were part of government policy to spread family planning knowledge and informed choices among the population. Cardinal Jaime Sin and former president Corazon Aquino joined forces to lead the movement against the national family planning program in the largest demonstration since the ouster of Ferdinand Marcos in 1986. Also criticized was the 85-page draft action plan for the International Conference on Population and Development (ICPD) scheduled for September 1994. Cardinal Sin accused President Clinton of using the action plan to promote worldwide abortion. Under the administration of President Fidel Ramos, family planning funding has quintupled and the number of family planning workers has increased from 200 to 8000. President Ramos has gone the farthest of any administration in opposing the Church's positions on contraception and abortion, although years ago Fidel Ramos and Cardinal Sin were allies in the effort to push out Ferdinand Marcos. The population of the Philippines is 85% Catholic, and laws reflect the Church's doctrine against divorce and abortion. The current growth rate is 2.3%, and the goal is to reduce growth to 2.0% by 1998, the end of Ramos's term in office. The population target is in accord with demographic goals proposed in the UN draft action plan. The Vatican has opposed the language in the plan and may have encouraged other religious leaders to join those opposed to the "war against our babies and children." Sin said that contraceptive distribution was "intrinsically evil" and should be stopped now. Ramos's administration stated that their policies and programs are not "in the hands of the devil" and there is support for the Church on family values and

    The Great East Japan Earthquake on 11 March 2011 caused major damage in northeastern Japan. The Kanto region experienced a massive electrical power shortage in the summer of 2011. A questionnaire was submitted to 354 hemodialysis clinics in Kanagawa prefecture and the Tokyo metropolitan area, excluding isolated islands, and 176 responses were analyzed (49.7%). The questions included evaluation of the availability of a private electricity generator, countermeasures in case of a planned outage, awareness of saving electricity, and improvement of safety of medical devices or electrical facilities after the earthquake. Only 12% of the clinics had private electricity generators and many clinics had no plans to introduce this facility. However, 96% of the clinics had established countermeasures to deal with a planned outage. Many clinics planned to provide dialysis on a different day or at a different time. All clinics had tried hard to establish procedures to save electricity in the summer of 2011, and 84% of the clinics had reconsidered and improved the safety of medical devices or electricity facilities after the earthquake. These results show that the awareness of crisis management was greatly improved in the wake of the earthquake.

    The transformation of the energy sector towards decentralized renewable energies (RE) requires also storage systems to ensure security of supply. The new "Power to Mobility" (PtM) technology is one potential solution to use electrical overproduction to produce methane for i.e. gas vehicles. Motivated by these fact, the paper presents a methodology for a GIS-based temporal modelling of the power grid, to optimize the site planning process for the new PtM-technology. The modelling approach is based on a combination of the software QuantumGIS for the geographical and topological energy supply structure and OpenDSS for the net modelling. For a case study (work in progress) of the city of Straubing (Lower Bavaria) the parameters of the model are quantified. The presentation will discuss the methodology as well as the first results with a view to the application on a regional scale.

    Full Text Available The development of diplexers for ECRH has been pursued at a number of institutes because of their attractive variety of applications: Power combination, non-mechanical, electrically controlled switching (of combined beams between launchers with tens of kHz, and discrimination of low-power ECE signals from high-power ECRH is feasible. In a first part, this paper reports on plasma experiments with a ring resonator (Mk IIa at ASDEX Upgrade. Commissioning experiments on fast switching between two launchers for synchronous stabilization of neoclassical tearing modes, as well as in-line ECE measurements have been performed, and experimental issues and first results are discussed. A clear influence of the switching phase on the amplitude of the 3/2 NTM mode was measured, complete stabilization could, however, not be demonstrated yet mainly due to imperfect resonator control. Concepts for improved tracking of the diplexers to the gyrotron frequency are presented. In a second part, the design of diplexers with ring resonators matched to HE11 fields is briefly discussed; these devices can be connected to corrugated waveguides without any mode converters. A compact version (MQ IV is under investigation, which is compatible with the ITER ECRH system (170 GHz, 63.5 mm waveguide, vacuum tight casing, with the final goal of high-power tests at the 170 GHz gyrotron facility at JAEA in Naka, Japan. First low-power test results are presented.

  13. Methods for planning and operating decentralized combined heat and power plants

    In recent years, the number of decentralized combined heat and power (DCHP) plants, which are typically located in small communities, has grown rapidly. These relatively small plants are based on Danish energy resources, mainly natural gas, and constitute an increasing part of the total energy production in Denmark. The topic of this thesis is the analysis of DCHP plants, with the purpose to optimize the operation of such plants. This involves the modelling of district heating systems, which are frequently connected to DCHP plants, as well as the use of heat storage for balancing between heat and power production. Furthermore, the accumulated effect from increasing number of DCHP plants on the total power production is considered. Methods for calculating dynamic temperature response in district heating (DH) pipes have been reviewed and analyzed numerically. Furthermore, it has been shown that a tree-structured DH network consisting of about one thousand pipes can be reduced to a simple chain structure of ten equivalent pipes without loosing much accuracy when temperature dynamics are calculated. A computationally efficient optimization method based on stochastic dynamic programming has been designed to find an optimum start-stop strategy for a DCHP plant with a heat storage. The method focuses on how to utilize heat storage in connection with CHP production. A model for the total power production in Eastern Denmark has been applied to the accumulated DCHP production. Probability production simulations have been extended from the traditional power-only analysis to include one or several heat supply areas. (au)

    2016-03-15

    High-speed railway system equipped with moving relay stations placed on the middle of the ceiling of each train wagon is investigated. The users inside the train are served in two hops via the orthogonal frequency-division multiple access (OFDMA) technology. In this work, we first focus on minimizing the total downlink power consumption of the base station (BS) and the moving relays while respecting specific quality of service (QoS) constraints. We first derive the optimal resource allocation solution in terms of OFDMA subcarriers and power allocation using the dual decomposition method. Then, we propose an efficient algorithm based on the Hungarian method in order to find a suboptimal but low complexity solution. Moreover, we propose an OFDMA planning solution for high-speed train by finding the maximal inter-BS distance given the required user data rates in order to perform seamless handover. Our simulation results illustrate the performance of the proposed resource allocation schemes in the case of the 3GPP Long Term Evolution-Advanced (LTE-A) and compare them with previously developed algorithms as well as with the direct transmission scenario. Our results also highlight the significant planning gain obtained thanks to the use of multiple relays instead of the conventional single relay scenario.

    Nuclear power plants are designed and built with systems dedicated to provide a high degree of protection to its workers, the population living in their neighborhoods and the environment. Among the requirements for ensuring safety there are the existence of the nuclear emergency plan. Due to the relationship between the actions contemplated in the emergency plan and the nuclear emergency exercise, it becomes possible to assess the quality of the nuclear emergency plan, by means of emergency exercise evaluation, The techniques used in this work aim at improving the evaluation method of a nuclear emergency exercise through the use of performance indicators in the evaluation of the structures, actions and procedures involved. The proposed model enables comparisons between different moments of an emergency plan directed to a nuclear power plant as well as comparisons between plans dedicated to different facilities.

A High Intensity Interval Training (HIIT)-based running plan improves athletic performance by improving muscle power. J Strength Cond Res 31(1): 146-153, 2017-This study aimed to examine the effect of a 5-week high-intensity intermittent training (HIIT)-based running plan on athletic performance and to compare the physiological and neuromuscular responses during a sprint-distance triathlon before and after the HIIT period. Thirteen triathletes were matched into 2 groups: the experimental group (EG) and the control group (CG). The CG was asked to maintain their normal training routines, whereas the EG maintained only their swimming and cycling routines and modified their running routine. Participants completed a sprint-distance triathlon before (pretest) and after (posttest) the intervention period. In both pretest and posttest, the participants performed 4 jumping tests: before the race (baseline), postswim, postcycling, and postrun. Additionally, heart rate was monitored (HRmean), whereas rate of perceived exertion (RPE) and blood lactate accumulation (BLa) were registered after the race. No significant differences (p ≥ 0.05) between groups were found before HIIT intervention (at pretest). Significant group-by-training interactions were found in vertical jumping ability and athletic performance: the EG improved jumping performance (∼6-9%, p ≤ 0.05, effect size (ES) > 0.7), swimming performance (p = 0.013, ES = 0.438), and running time (p = 0.001, ES = 0.667) during the competition, whereas the CG remained unchanged (p ≥ 0.05, ES HIIT-based running plan combined with the high training volumes of these triathletes in swimming and cycling improved athletic performance during a sprint-distance triathlon. This improvement may be due to improved neuromuscular characteristics that were transferred into improved muscle power and work economy.

    The Nuclear Spectroscopic Telescope Array (NuSTAR) is the first focusing hard X-ray mission in orbit and operates in the 3-79 keV range. NuSTAR's sensitivity is roughly two orders of magnitude better than previous missions in this energy band thanks to its superb angular resolution. Since its launch in 2012 June, NuSTAR has performed excellently and observed many interesting sources including four magnetars, two rotation-powered pulsars and the cataclysmic variable AE Aquarii. NuSTAR also discovered 3.76-s pulsations from the transient source SGR J1745-29 recently found by Swift very close to the Galactic center, clearly identifying the source as a transient magnetar. For magnetar 1E 1841-045, we show that the spectrum is well fit by an absorbed blackbody plus broken power-law model with a hard power-law photon index of approximately 1.3. This is consistent with previous results by INTEGRAL and RXTE. We also find an interesting double-peaked pulse profile in the 25-35 keV band. For AE Aquarii, we show that the spectrum can be described by a multi-temperature thermal model or a thermal plus non-thermal model; a multi-temperature thermal model without a non-thermal component cannot be ruled out. Furthermore, we do not see a spiky pulse profile in the hard X-ray band, as previously reported based on Suzaku observations. For other magnetars and rotation-powered pulsars observed with NuSTAR, data analysis results will be soon available.

    The Nuclear Spectroscopic Telescope Array (NuSTAR) is the first focusing hard X-ray mission in orbit and operates in the 3-79 keV range. NuSTAR's sensitivity is roughly two orders of magnitude better than previous missions in this energy band thanks to its superb angular resolution. Since its launch in 2012 June, NuSTAR has performed excellently and observed many interesting sources including four magnetars, two rotation-powered pulsars and the cataclysmic variable AE Aquarii. NuSTAR also discovered 3.76-s pulsations from the transient source SGR J1745-29 recently found by Swift very close to the Galactic Center, clearly identifying the source as a transient magnetar. For magnetar 1E 1841-045, we show that the spectrum is well fit by an absorbed blackbody plus broken power-law model with a hard power-law photon index of ~1.3.

    In liberalized electricity markets, generation companies bid their hourly generation in order to maximize their profit. The optimization of the generation bids over a short-term weekly period must take into account the action of the competing generation companies and the market-price formation rules and must be coordinated with long-term planning results. This paper presents a three stage optimization process with a data analysis and parameter calculation, a linearized unit commitment, and a nonlinear generation scheduling refinement. Although the procedure has been developed from the experience with the Spanish power market, with minor adaptations it is also applicable to any generation company participating in a competitive market system.

    Line-focus solar collectors, in particular parabolic trough collectors, are the most mature and proven technology available for producing central electricity from concentrated solar energy. Because this technology has over 25 years of successful operational experience, resulting in a low perceived risk, it is likely that it will continue to be a favorite of investors for some time. The concentrating solar power (CSP) industry is developing parabolic trough projects that will cost billions of dollars, and it is supporting these projects with hundreds of millions of dollars of research and development funding. While this technology offers many advantages over conventional electricity generation -- such as utilizing plentiful domestic renewable fuel and having very low emissions of greenhouse gases and air pollutants -- it provides electricity in the intermediate power market at about twice the cost of its conventional competitor, combined cycle natural gas. The purpose of this document is to define a set of activities from fiscal year 2011 to fiscal year 2016 that will make this technology economically competitive with conventional means.

  15. Patient-specific stopping power calibration for proton therapy planning based on single-detector proton radiography.

    A simple robust optimizer has been developed that can produce patient-specific calibration curves to convert x-ray computed tomography (CT) numbers to relative stopping powers (HU-RSPs) for proton therapy treatment planning. The difference between a digitally reconstructed radiograph water-equivalent path length (DRRWEPL) map through the x-ray CT dataset and a proton radiograph (set as the ground truth) is minimized by optimizing the HU-RSP calibration curve. The function of the optimizer is validated with synthetic datasets that contain no noise and its robustness is shown against CT noise. Application of the procedure is then demonstrated on a plastic and a real tissue phantom, with proton radiographs produced using a single detector. The mean errors using generic/optimized calibration curves between the DRRWEPL map and the proton radiograph were 1.8/0.4% for a plastic phantom and -2.1/ - 0.2% for a real tissue phantom. It was then demonstrated that these optimized calibration curves offer a better prediction of the water equivalent path length at a therapeutic depth. We believe that these promising results are suggestive that a single proton radiograph could be used to generate a patient-specific calibration curve as part of the current proton treatment planning workflow.

    In this study, a multistage interval-stochastic regional-scale energy model (MIS-REM) is developed for supporting electric power system (EPS) planning under uncertainty that is based on a multistage interval-stochastic integer linear programming method. The developed MIS-REM can deal with uncertainties expressed as both probability distributions and interval values existing in energy system planning problems. Moreover, it can reflect dynamic decisions for electricity generation schemes and capacity expansions through transactions at discrete points of a multiple representative scenario set over a multistage context. It can also analyze various energy-policy scenarios that are associated with economic penalties when the regulated targets are violated. A case study is provided for demonstrating the applicability of the developed model, where renewable and non-renewable energy resources, economic concerns, and environmental requirements are integrated into a systematic optimization process. The results obtained are helpful for supporting (a) adjustment or justification of allocation patterns of regional energy resources and services, (b) formulation of local policies regarding energy consumption, economic development, and energy structure, and (c) analysis of interactions among economic cost, environmental requirement, and energy-supply security.

    The Power Control and Rain Fade Software was developed at the NASA Lewis Research Center to support the Advanced Communications Technology Satellite High Burst Rate Link Evaluation Terminal (ACTS HBR-LET). The HBR-LET is an experimenters terminal to communicate with the ACTS for various experiments by government, university, and industry agencies. The Power Control and Rain Fade Software is one segment of the Control and Performance Monitor (C&PM) Software system of the HBR-LET. The Power Control and Rain Fade Software automatically controls the LET uplink power to compensate for signal fades. Besides power augmentation, the C&PM Software system is also responsible for instrument control during HBR-LET experiments, control of the Intermediate Frequency Switch Matrix on board the ACTS to yield a desired path through the spacecraft payload, and data display. The Power Control and Rain Fade Software User's Guide, Version 1.0 outlines the commands and procedures to install and operate the Power Control and Rain Fade Software. The Power Control and Rain Fade Software Maintenance Manual, Version 1.0 is a programmer's guide to the Power Control and Rain Fade Software. This manual details the current implementation of the software from a technical perspective. Included is an overview of the Power Control and Rain Fade Software, computer algorithms, format representations, and computer hardware configuration. The Power Control and Rain Fade Test Plan provides a step-by-step procedure to verify the operation of the software using a predetermined signal fade event. The Test Plan also provides a means to demonstrate the capability of the software.

  5. Effective particle energies for stopping power calculation in radiotherapy treatment planning with protons and helium, carbon, and oxygen ions

    Science.gov (United States)

    Inaniwa, T.; Kanematsu, N.

    2016-10-01

    The stopping power ratio (SPR) of body tissues relative to water depends on the particle energy. For simplicity, however, most analytical dose planning systems do not account for SPR variation with particle energy along the beam’s path, but rather assume a constant energy for SPR estimation. The range error due to this simplification could be indispensable depending on the particle species and the assumed energy. This error can be minimized by assuming a suitable energy referred to as an ‘effective energy’ in SPR estimation. To date, however, the effective energy has never been investigated for realistic patient geometries. We investigated the effective energies for proton, helium-, carbon-, and oxygen-ion radiotherapy using volumetric models of the reference male and female phantoms provided by the International Commission on Radiological Protection (ICRP). The range errors were estimated by comparing the particle ranges calculated when particle energy variations were and were not considered. The effective energies per nucleon for protons and helium, carbon, and oxygen ions were 70 MeV, 70 MeV, 131 MeV, and 156 MeV, respectively. Using the determined effective energies, the range errors were reduced to  ⩽0.3 mm for respective particle species. For SPR estimation of multiple particle species, an effective energy of 100 MeV is recommended, with which the range error is  ⩽0.5 mm for all particle species.

  6. The Economic Merits of Flexible Carbon Capture and Sequestration as a Compliance Strategy with the Clean Power Plan.

    2017-02-07

    Carbon capture and sequestration (CCS) may be a key technology for achieving large CO2 emission reductions. Relative to "normal" CCS, "flexible" CCS retrofits include solvent storage that allows the generator to temporarily reduce the CCS parasitic load and increase the generator's net efficiency, capacity, and ramp rate. Due to this flexibility, flexible CCS generators provide system benefits that normal CCS generators do not, which could make flexible CCS an economic CO2 emission reduction strategy. Here, we estimate the system-level cost effectiveness of reducing CO2 emissions with flexible CCS compared to redispatching (i.e., substituting gas- for coal-fired electricity generation), wind, and normal CCS under the Clean Power Plan (CPP) and a hypothetical more stringent CO2 emission reduction target ("stronger CPP"). Using a unit commitment and economic dispatch model, we find flexible CCS achieves more cost-effective emission reductions than normal CCS under both reduction targets, indicating that policies that promote CCS should encourage flexible CCS. However, flexible CCS is less cost effective than wind under both reduction targets and less and more cost effective than redispatching under the CPP and stronger CPP, respectively. Thus, CCS will likely be a minor CPP compliance strategy but may play a larger role under a stronger emission reduction target.

    1996-12-31

    In this work it is presented an original methodology of multistage planning, with conflictive objectives and restrictions, incorporating the concept of uncertainties. To do so, the proposed paradigm is based on the Dynamic Programming which comprehends the multistage subject to conflictive restrictions; on the Fuzzy Sets Theory, through the decisions and fuzzy numbers, which model the uncertainties and ambiguous decisions referent to qualitative variables; and on the consideration of evolutional rules associated to network flow algorithm. In its conceptual elaboration, the paradigm is developed in a very ample way, of generalized application to a well defined class of planning problems Particularly, the model fits in the flexible planning, which has been very discussed in the recent literature. Flexible planning must be understood as the one which allows to the planner, under well-defined limits, the evaluation of the planning policy composed by strips of options (discreet or continuous), associated to uncertainty levels related to the real world. In order to validate and consolidate the theoretic concepts, it was elaborated an algorithm turned to the aggregated planning of the distribution of electric energy, that presents intrinsic characteristics which are perfectly fitted in the paradigm`s applicability.

    This work presents a first exertion to evaluate the environmental impacts due to the operation of planned gas power plants. This study was carried out with the model EcoSense, that is a computer program developed for the quantification of environmental impacts and their external costs resulting from the operation of thermal power plants or other industrial activities. EcoSense is still in development and the achieved results should still be considered with caution although it becomes clear the potentiality of the use of this tool in the support of the decision making process in energy planning. Based on the method of approach of the damage function established in the ExternE project this program provides models for an integrated evaluation of the impact rate from the air pollutants resulting from burning fossil fuel, which are transported by the air.

A web-based solution (electronic ICP [e-ICP] was used to support the planning and documentation. The aim of this study was to investigate how web-based collaboration challenged user and professional roles. Methods: Data were obtained from 15 semistructured interviews with users and eight with care professionals, and from two focus-group interviews with eight care professionals in total. The data were analyzed using systematic text condensation in a stepwise analysis model. Results: Users and care professionals took either a proactive or a reluctant role in e-ICP collaboration. Where both user and care professionals were proactive, the pairing helped to ensure that the planning worked well; so did pairings of proactive care professionals and reluctant users. Proactive users paired with reluctant care professionals also made care planning work, thanks to the availability of information and the users' own capacity or willingness to conduct the planning. Where both parties were reluctant, no planning activities occurred. Conclusion: Use of the e-ICP challenged the user–professional relationship. In some cases, a power transition took place in the care process, which led to patient empowerment. This knowledge might be used to develop a new understanding of how role function can be challenged when users and care professionals have equal access to health care

    The increased interconnection and automation of critical infrastructures enlarges the complexity of the dependency structures and - as consequence - the danger of cascading effects, e.g. causing area-wide blackouts in power supply networks that are currently after deregulation operated closer to their limits. New tools or an intelligent combination of existing approaches are required to increase the survivability of critical infrastructures. Within the IRRIIS project the expert system CRIPS was developed based on network simulations realised with PSS®SINCAL, an established tool to support the analysis and planning of electrical power, gas, water or heat networks. CRIPS assesses the current situation in power supply networks analysing the simulation results of the physical network behaviour and recommends corresponding decisions.

    The pluri-annual planning of power generation investments (PPI) is provided by article 6 of the law from February 10, 2000 relative to the modernization and development of the electric utility. The PPI is the concrete translation of the energy policy and aims to identify the necessary investments with respect to the security of power supplies and beyond the already known commitments. In the framework of market deregulation and respect of competition, the PPI is limited to the identification of such investments but not to their realization. This document, which corresponds to the 2005 exercise, is the second report to the Parliament. It stresses on the following points: the mastery of power demand and the demand scenarios, the level of accepted risk, the carrying out of the development of renewable energy sources (5 GW by 2010 and 12.5 GW by 2016 for wind power, and 6 TWh more for biomass by 2016), the start-up of an EPR reactor in 2012, the investment needs for classical thermal power plants (+2.6 GW of diesel fuel power plants and +500 MW of combustion turbines as decided by EdF), the development of production means in 2 regions with specific needs: Provence-Alpes-Cote d'Azur and Bretagne (Brittany), and also in insular areas (Corsica and overseas territories), and the reflexions to carry on in continuation of the PPI.

    The unprecedented earthquake(magnitude-9 in the Japanese seismic intensity scale)hit off the east coast of Japan on March 11, 2011. Consequently, there were planned power outages in the area nearby Tokyo to avoid massive blackouts caused by a stoppage of Fukushima nuclear plants.Our clinic located in Kawasaki city was also hit by the earthquake(magnitude- 5).During the period of two months(March and April 2011), we had a total of 52 patients with home respiratory care (5-TPPV, 11-NPPV and 36-HOT)at that time.Two out of three 24 hour-TPPV users had no external battery.After the earthquake, there was a 7-hour electricity failure in some areas, and a patient with ASV(adaptive servo ventilator)was living there.Moreover, 3-hour/day power outages were carried out from March 14 to March 28, affecting people's everyday lives. However, the patient had no harmful influences from the power failure because a ventilation company lent us an external battery(4-9 hour life capacity)for the patients, and we were able to avoid an emergency situation caused by the power failure.In conclusion, we ought to be prepared for patients with home mechanical ventilation in the future toward unforeseen large scale power outages.

    Mexico's transition to a modern wholesale power market will place new demands on how regulators evaluate and approve transmission expansion projects. Transmission projects in a modern wholesale market fulfill one of several needs, and utilities, regional transmission organizations, and regulatory authorities in the United States have encountered comparable challenges in their market transitions to ensure projects meeting each type of need can be built. The purpose of this report is to open a window to view that experience. The report examines key practices of different U.S. jurisdictions that have moved from transmission planning to transmission approval, and it focuses on the role of the regulator in supporting a planning process that equitably meets identified needs.

    The article 6 of the law from February 10, 2000, relative to the modernization and development of the electric utility, schedules a pluri-annual planning of the production investments (PPI) which represents a concrete translation of the energy policy in the domain of electricity. The PPI will allow to reach the energy policy goals using a balanced development of the national production means in terms of primary energy sources, techniques of production and geographical distribution of investments. This document is the first PPI report to the parliament. It is based on the scheme of energy collective services and on a provisional status made by the manager of the transportation network (RTE). In 2010, renewable energies should cover 21% of the French electricity needs. This ratio will be reached mainly thanks to the development of wind power (7000 to 14000 MW of installed power, which represents 20 to 35 TWh of additional production). Hydro-power should be increased of 8 TWh max, depending on the public policies implemented, and biomass will have a significant contribution too. On the other hand, actions of mastery of the electricity demand will have to be implemented. From 2008 onward, the decommissioning of several power plants will impose to find new solutions to satisfy the peak power needs. The covering of consumption peaks requires a correlation study of the power peaks at the European scale. Finally, the situation of non-interconnected areas and of areas with fragile supply has been carefully considered. The creation of new power production means must be envisaged in most of these areas.

    A female patient in her sixties with schizophrenia had secretly disposed of all her medication and was not cooperating with hospital staff for about four months. During one of our consultations she mentioned that she wanted to be out of hospital by a certain date. That date happened to be her grandchild's birthday. It was at this point that she shared her goals with us, and voluntarily started having treatment. She was able to return home three months later, just in time to celebrate her grandchild's birthday with her family. A male patient in his sixties was able to leave the seclusion room after 10 years. The first doctor in charge and other hospital staff had firmly believed that releasing him from the seclusion room wasn't a possibility. However the patient decided he wanted to be discharged and was interested in finding out how to go about it. The moment he realized it was possible, his outlook changed immensely. He gradually started to open up and communicate better with his new doctor in charge, and was able to work towards his newly found goals. Staff members were also surprised when he was able to leave the seclusion room. They realized this patient was another person like them who had dreams and goals, and stopped stereotyping patients who seemed to be 'difficult to handle'. I have always experienced the power of goal sharing at clinical scenes, and have noticed its importance for patients making a start on the road to recovery. In order to discuss goals and the way to go about achieving them, I use a simple drawing of a mountain. I call this mountain 'A Personal Goal Map'. I like to think of myself (the doctor) as the mountain guide, and my patient as the mountain climber. The three key philosophies are acknowledging individuality, diversity and freedom. These are important when we think about where we are now, where we are going, and where we want to be. Firstly at the start point, we need to define the patient's problem and discuss ideas and goals

    It is difficult to precisely take complex paths and environmental costs into account in traditional power network planning methods. This paper presented a spatial power network planning model considering electric line routing and substation location based on rasterized three-dimension map. The objective function in the proposed model was to minimize the investment and operation cost of the power network while subject to a list of constraints to ensure the security of power system and the feasibility of electric line route. It is a mixed integer, non-linear, non-convex optimization problem, which is complex and computationally demanding. In view of this, this paper proposed a bi-level structure in which the master problem was traditional power network planning considering substation location to be solved by genetic algorithm, while the sub problems were route optimizations for candidate lines to be solved by dynamic programming. Meanwhile, a memory structure was introduced in genetic algorithm to improve the computational efficiency. Numerical case studies utilizing IEEE Graver-6 system, IEEE 118-bus system and a real power system illustrated the effectiveness of the proposed approach for the spatial power network planning problem.%针对传统电网规划方法难于有效计及复杂路径及环境成本的问题,基于栅格化三维地图,以设备投资成本和运行费用综合最小为目标函数,考虑传统电网规划约束和线路路径优化约束,建立了考虑路径优化和变电站选址的空间电网规划模型。该模型是一个复杂的混合整数非线性规划模型,将其分解为考虑变电站选址的电网规划上层问题和线路路径优化下层问题,并提出适合求解该模型的遗传算法和动态规划法相结合的混合优化算法,该混合优化算法在采用遗传算法解决网架结构优化和变电站选址优化的同时,将动态规划法嵌入到遗传算法中,求

    Full Text Available Aquaculture expansion is a political priority in Norway, despite simmering conflicts and competing claims. We expand on this hypothesis and analyze the Norwegian governance system by adding stakeholder theory in case of a simulated model of the effects of municipal coastal zone planning in the municipality of Frøya, Norway. One cannot analyze the governance system in Norway without fully comprehending the perspectives of the stakeholders involved. Different stakeholders will react and respond differently and have conflicting presumptions basing their actions towards the planning process for coastal areas. They will also have different levels of power and abilities to influence the system. The article presents the interdisciplinary, first generation development of an agent based simulation model that mimics the outcomes of coastal zone planning for a stakeholder groups, the commercial fishers and the aquaculture industry, based on qualitative input from legislation, regulations and stakeholder workshops. We proceed with verifying the applicability of this simulator in light of the key actors involved, namely the commercial fishers. We found that the simulator had two outcomes for the commercial fishers that were consistently recurring, namely collapse and stability, based on the simulated occurrences of complaints by the stakeholders, with the latter being the de facto perceptions of actuality by the commercial fishers. Using stakeholder theory, we argue that the aquaculture industry’s role has the saliency of an Important Stakeholder in Frøya has steered the commercial fishers, who has the role of Dependent Stakeholders according to stakeholder theory, to no longer see any legitimacy in the process in that their complaints were never upheld because of their lack of the attribute Power.

    Facing the air pollution problems in China, emission control strategies have been implemented within the framework of national Five-Year Plan (FYP). According to the lack of post-assessment studies in the literature, this study assessed the effectiveness of the SO2 emission control policies on power plants after the 11th FYP (2006-2010) by modeling emission control scenarios. The idealized emission control policy (the PS90 scenario with assumption of 90% SO2 emission reduction from power plants) could reduce the SO2 and SO4(2-) concentrations by about 51 and 14%, respectively, over the Yangtze River Delta region. While the actual emission control condition (the P2010 scenario based on the actual emissions from power plants in 2010) demonstrated that the actual reduction benefits were 30% of SO2 and 9% of SO4(2-). On the city scale, the P2010 scenario imposed positive benefits on Shanghai, Nanjing, Nantong, and Hangzhou with SO2 reductions of about 55, 12, 30, and 21%, respectively, while an 11% increase of SO2 concentration was found in Ningbo. The number of days exceeding China's National Ambient Air Quality Standard of Class I daily SO2 concentration was estimated to be 75, 52, 7, 77, and 40 days for Shanghai, Nanjing, Nantong, Ningbo, and Hangzhou under the real SO2 control condition (P2010). The numbers could be decreased by 16, 11, 2, 21, and 11% if the control effect reaches the level of the PS90 scenario. This study serves as a scientific basis to design capable enforcement of emission control strategies in China in the future national plans.

    2015-03-01

    Full Text Available Diversity and multiplicity of factors affecting the exploitation from power systems, makes completely impossible to solve this problem. Therefore, the optimal planning problem in system exploitation is decomposed into several sub-problems. One of exploitation sub-problems from power systems is economic dispatch of production on system units in order to meet the consumption needs. This is an optimization problem in real power systems, with great dimensions and multiple constraints including economic dispatch of system, transfer network restrictions, rate of increase and decrease in production, prohibited areas of operation units, spinning reserve storage of systems, loading effects of steam valves, multi-fuel production units. A suitable algorithm based on probabilistic search methods has been proposed in order to solve the proposed model effectively in the future. An experimental system with complex solution space is used in order to demonstrate the effectiveness of proposed method and new model and it is compared with some of the latest techniques for solving problem. In this paper, MATLAB software is used for above reviews.

    2016-03-01

    Full Text Available An Extension Taguchi Method (ETM is proposed on the optimized allocation of equipment capacity for solar cell power generation, wind power generation, full cells, electrolyzer and hydrogen tanks. The ETM is based on the domain knowledge containing the product specifications and allocation levels provided by suppliers and design factors since most of the renewable energy equipment available in the market comes with a specific capacity. A proper orthogonal array is used to collect 18 sets of simulation responses. The extension theory is introduced to determine the correlation function, and factor effects are used to identify the optimized capacity allocation. The hours of power shortage are simulated using Matlab for all capacity allocations at the lowest establishment cost and the optimized capacity allocation of loss of load probability (LOLP. Finally, the extension theory, extension AHP theory, ETM and Analytic Hierarchy Process (AHP are used to determine the optimized capacity allocation of the system. Results are compared for the above four optimization simulation methods and verify that the proposed ETM surpasses the others on achieving the optimized capacity allocation.

    Directory of Open Access Journals (Sweden)

    Babak Yousefi-Khangah

    2014-12-01

    Full Text Available If determination of location and size of Distributed Generation (DG are applied accurately, the DG’s ability will improve the network situation and reduce operation costs. In this paper, various market conditions are considered to maximize the benefit of DG’s presence and make a trade off among advantages of DG, network situation, and Distribution Company (DISCO owners. To determine the optimal location and size of DG, two methods of the cost minimization and the nodal pricing are combined. In addition to evaluating the impact of parameters such as variation of energy price and load on objective function, effect of these parameters on location and size of DG is considered. To confirm the results, impact of loads which are dependent on voltage and variation of the power factor of the DG units is applied and then effect of power factor on optimal location and size of DG is shown. A method is proposed for convergence of different results which is caused by different power factors. To observe long-term impact of the DG’s presence in the network, a load growth for five years is considered annually. Study is carried out on IEEE30 bus test circuit.

    2010-12-15

    According to the current regulatory framework, it is the responsibility of the holder of a licence to own or operate a nuclear power reactor to prepare a calculation of the costs for all measures that are needed for the management and disposal of spent nuclear fuel that has been used in the reactors and other radioactive waste products and to decommission and dismantle the reactor plants. The regulatory framework comprises the Act (2006:647) and the Ordinance (2008:715) on Financial Measures for the Management of Residual Products from Nuclear Activities (hereinafter referred to as the Financing Act and the Financing Ordinance, respectively). This cost calculation shall be submitted periodically to the Government or the authority designated by the Government. SKB's owners have assigned SKB the task of preparing such a cost calculation jointly for the licensees of the Swedish nuclear power plants. The present report, which is the twenty-eighth annual plan report, gives an updated compilation of these costs. As in previous years' reports, the costs are shown for two cases. The first case concerns the system as a whole, including management and disposal of radioactive operational waste plus certain waste deriving from other facilities than those belonging to SKB's owners. This case has been based on a scenario concerning reactor operation that is based on the nuclear power plant owners' current planning. The second case concerns the system with the restrictions that follow from the regulatory framework, which stipulates the time for operation of the reactors that is supposed to serve as a basis for fees. The report is divided into three parts: Chapter 1 provides background information regarding the Financing Act and SKB's calculation model. Chapter 2 provides information on the underlying calculation, which is based on current plans for reactor operation and SKB's activities. Chapter 3 presents the cost estimates required by the Financing

    2013-01-01

    Although routine dental checkups are important for both oral and overall health, several factors influence young adults' use or nonuse of dental services. The two studies included in this report tested the theory of reasoned action (TRA), the theory of planned behavior (TPB), and an expanded TPB model in predicting young adults' routine dental checkups. Additionally, the study tested the perceived message effectiveness of TPB-based messages. Results support the use of an expanded TPB model (particularly adding satisfaction with the dentist and environmental constraints to the traditional model) for an understanding of routine dental checkup intention and behavior, and, most notably, provide support for the use of subjective norm-based messages to prompt dental checkups. This study lays the groundwork for a health communication campaign encouraging routine dental checkups among young adults. The use of targeting and tailoring to design effective oral health media campaign messages is discussed.

    Wind energy gained in importance for electric power supply due to financial incentives for wind turbine generators (WTG) as politically favoured renewable energy source and the resulting technical further development. Building a relevant landscape element, the approvability of the structure plays a decisive role in planning and design of WTG. Another topic is the structural (and the related economical) optimisation of the plants in terms of most effective exploitation of the building material. As most of the WTG are fabricated in small batch series, certification or type testing is advantageous. Using the example of a WTG with savonius rotor, the proceeding of the structural analysis is shown including the most important load assumptions and an outlook on the required verifications. (orig.)

    In sub-Saharan Africa, high burdens of HIV and unmet need for contraception often coexist. Research emphasises the need to engage men and couples in reproductive health, yet couples' negotiations around fertility and family planning in the context of HIV have been sparsely studied. This study examined the gendered power dynamics that frame women's and couples' negotiations of contraceptive use in western Kenya. We conducted 76 in-depth interviews with 38 couples, of whom 22 couples were concordant HIV-positive. Qualitative data were analysed using a grounded theory approach. Direct communication around contraception with men was often challenging due to perceived or expressed male resistance. A substantial minority of women avoided male reproductive decision-making authority through covert contraceptive use, with concern for severe consequences when contraceptive use was discovered. Many men assumed that family planning use signified female promiscuity and that infidelity motivated covert use. Men were more willing to use condoms to avoid HIV re-infection or on the recommendation of HIV care providers, which allowed some women leverage to insist on condom use. Our findings highlight the tension between male dominated reproductive decision making and women's agency and point to the need for gender transformative approaches seeking to challenge masculinities that negatively impact health.

    This paper describes the Neutral Beam Injection system which is presently being designed for the International Tokamak Experimental Reactor, ITER, in Europe Japan and Russia, with co-ordination by the Joint Central Team of ITER at Naka, Japan. The proposed system consists of three negative ion based neutral injectors, delivering a total of 50 MW of 1 MeV D{sup 0} to the ITER plasma for a pulse length of >1000 s. Each injectors uses a single caesiated volume arc discharge negative ion source, and a multi-grid, multi-aperture accelerator, to produce about 40 A of 1 MeV D{sup -}. This will be neutralized by collisions with D{sub 2} in a sub-divided gas neutralizer, which has a conversion efficiency of about 60%. The charged fraction of the beam emerging from the neutralizer is dumped in an electrostatic residual ion dump. A water cooled calorimeter can be moved into the beam path to intercept the neutral beam, allowing commissioning of the injector independent of ITER. ITER is scheduled to produce its first plasma at the beginning of 2008, and the planning of the R and D, construction and installation foresees the neutral injection system being available from the start of ITER operations.

    Due to strong increase of solar power generation, the predictions of incoming solar energy are acquiring more importance. Photovoltaic and solar thermal are the main sources of electricity generation from solar energy. In the case of solar thermal energy plants with storage energy system, its management and operation need reliable predictions of solar irradiance with the same temporal resolution as the temporal capacity of the back-up system. These plants can work like a conventional power plant and compete in the energy stock market avoiding intermittence in electricity production. This work presents a comparisons of statistical models based on time series applied to predict half daily values of global solar irradiance with a temporal horizon of 3 days. Half daily values consist of accumulated hourly global solar irradiance from solar raise to solar noon and from noon until dawn for each day. The dataset of ground solar radiation used belongs to stations of Spanish National Weather Service (AEMet). The models tested are autoregressive, neural networks and fuzzy logic models. Due to the fact that half daily solar irradiance time series is non-stationary, it has been necessary to transform it to two new stationary variables (clearness index and lost component) which are used as input of the predictive models. Improvement in terms of RMSD of the models essayed is compared against the model based on persistence. The validation process shows that all models essayed improve persistence. The best approach to forecast half daily values of solar irradiance is neural network models with lost component as input, except Lerida station where models based on clearness index have less uncertainty because this magnitude has a linear behaviour and it is easier to simulate by models.

    The power succession in a family business,including the continuation of property,reputation and social status as well as the inheritance of power from generation to generation, determines the sustainable development or even survival of a family business. With the "inheritance model" being the main trend, family businesses should make a scientific planning on issues such as the selection and training of the successors, the optimal timing of succession and the withdrawal of the old generation, etc. To promote the execution of the planning, family businesses should also build up a coordinating mechanism, pay close attention to the responses of all stakeholders and fully value the significance of the family spirit and the transmission of corporate culture based on the formality and normalization of succession planning.%家族企业权力传承既是企业所有权和控制权由上一代传递给下一代的过程,同时也是家族财产、声誉和社会地位的传递,关系到家族企业的持续发展乃至生死存亡。在“予承父业”的主流模式下,家族企业谘须对权力传承所涉及的继任者选择、继任者培养、权力交接的最优时机设计以及老一代家族企业主的退出等问题进行科学的规划设计。为推动传承规划的顺利执行,家族企业还应在确保传承规划设计的正式性和规范性的基础上,建立有利于权力传承的协调机制,密切关注各利益相关者的反应并充分考虑到家族精神和企业文化的传承的重要意义。

    This study comprises two major tasks. First, it includes an independent assessment of the methods and assumptions used in calculating evacuation time estimates (ETEs) applicable to the general population for a peak population scenario in the emergency planning zone {EPZ) of the Seabrook Nuclear Power Station. This consists of a review and analysis of previous work by Public Service of New Hampshire {PSNH) and the Federal Emergency Management Agency (FEMA), as well as an independent calculation of evacuation times using the CLEAR model for the demographic data reported by PSNH. Secondly, this study includes independent estimations of evacuation time for the peak population scenario developed using demographic data prepared by the U.S. Nuclear Regulatory Commission {NRC). These evacuation time estimates are approximately 60% and 84% greater, respectively, than the estimate provided by PSNH for a simulataneous evacuation of the entire EPZ under peak conditions. The CLEAR model, which was developed by Pacific Northwest Laboratory {PNL) under the sponsorship of the. NRC, was also used for these latter calculations. The results of this study reveal the importance of the assumptions used for calculating evacuation times. Because traffic routings and management plans have not been prepared for the area, the CLEAR calculations utilized indepdently prepared traffic routings and assumptions. A detailed analysis of the results suggests that the ETEs submitted by PSNH are consistent with the methods and assumptions which provide the bases for PSNH•s evacuation time estimates. Differences among evacuation time estimates stem largely from differences jn the assumed size of the evacuating population and the estimated effectiveness of traffic controls.

    The United States has and will likely continue to obtain an increasing share of its electricity from solar photovoltaics (PV) and wind power, especially under the Clean Power Plan (CPP). The need for additional solar PV modules and wind turbines will, among other things, result in greater demand for a number of minor metals that are produced mainly or only as byproducts. In this analysis, the quantities of 11 byproduct metals (Ag, Cd, Te, In, Ga, Se, Ge, Nd, Pr, Dy, and Tb) required for wind turbines with rare-earth permanent magnets and four solar PV technologies are assessed through the year 2040. Three key uncertainties (electricity generation capacities, technology market shares, and material intensities) are varied to develop 42 scenarios for each byproduct metal. The results indicate that byproduct metal requirements vary significantly across technologies, scenarios, and over time. In certain scenarios, the requirements are projected to become a significant portion of current primary production. This is especially the case for Te, Ge, Dy, In, and Tb under the more aggressive scenarios of increasing market share and conservative material intensities. Te and Dy are, perhaps, of most concern given their substitution limitations. In certain years, the differences in byproduct metal requirements between the technology market share and material intensity scenarios are greater than those between the various CPP and No CPP scenarios. Cumulatively across years 2016–2040, the various CPP scenarios are estimated to require 15–43% more byproduct metals than the No CPP scenario depending on the specific byproduct metal and scenario. Increasing primary production via enhanced recovery rates of the byproduct metals during the beneficiation and enrichment operations, improving end-of-life recycling rates, and developing substitutes are important strategies that may help meet the increased demand for these byproduct metals.

    This thesis considers uncertainty on the long term generation expansion planning in the Brazilian Electric System, under a Real Options Approach . First, Real Options Theory is used to demonstrate the importance of thermo power plants insertion in Brazil, through a flexibility valuation on hydrothermal system. This is the first objective of this thesis. In the second part a Real Options Model is proposed to support long term expansion studies, based in a levelized costs analysis. The adequacy of proposed models to real problem is illustrated by a case study of the Brazilian Power System. The results show the importance of the energetic matrix diversification on the Long Term Planning. In the expansion model proposed, results are in favor of higher participation of biomass, nuclear power and coal in Brazilian electricity generation matrix. (author)

    By referring to the influence of integration of distributed generators (DGs) on distribution networks, candidate solutions for DGs are given by analyzing the power loss, voltage distribution, and customer reliability demand. To balance the benefits between independent power suppliers (IPSs) and power distribution companies (PDCs), a multi-objective planning model is developed that takes both maximum DGs unit cost rate and maximum benefits from the improved grid into account. The model proposed involves cost and benefit, environment improvement, network loss, voltage quality, reliability, delayed network renewal etc. Based on the non-inferior sorting genetic algorithm, the solving method uses the segment chromosome operations to realize simultaneous optimization between type, site and size. The simulation results of an IEEE 69-bus system show that the method proposed is fast, reliable and effective in the determination of the location and capacity of DGs as well as the benefits balance between IPS with DGs and PDC.%结合分布式电源接入对配电网的影响,通过对系统网损、电压分布及用户可靠性要求的综合分析确定出了分布式电源候选安装位置解集.为实现分布式电源独立发电商和配电公司的利益均衡,建立了分布式电源单位成本收益和其接入后改善电网所得收益最大化的多目标规划模型,所建模型考虑了分布式电源的投资成本、卖电收益、环境改善,以及网损、电压质量、可靠性和延缓网络更新等.求解方法基于改进非劣排序遗传算法,通过使用分段式染色体操作实现分布式电源类型、位置和容量的同时优化规划.IEEE 69节点仿真结果表明,该方法可协调拥有分布式电源的独立发电商和配电公司之间的利益问题.

    In this paper we argue that the use of the communicative theory of Jürgen Habermas in planning theory is problematic because it hampers an understanding of how power shapes planning. We posit an alternative approach based on the power analytics of Michel Foucault which focuses on ?what is actually...... done?, as opposed to Habermas?s focus on ?what should be done?. We discuss how the Foucauldian stance problematises planning, asking difficult questions about the treatment of legitimacy, rationality, knowledge and spatiality. We conclude that Foucault offers a type of analytic planning theory which...

    The power system static operation planning has a main objective the determination of performance strategies which satisfy operational criteria. A fuzzy set decision model which takes the load attainment and the compromise between optimality and critical operational constraints into account is presented. The prime characteristic of this methodology is the incorporation of the planner`s preferences structure in a decision process modeled by fuzzy sets. A routine of optimal power flow calculation is used as a computational tool for solving the nonlinear model of the electric power system and for defining the universe of discourse of the decision-making problem. tests were carried on a 30-bus IEEE system in order to find a compromise solution of electric operational goal versus reactive power generation limits. Results and conclusions are presented. (author) 28 refs., 32 figs.

    2008-12-15

    A company that has a licence to own a nuclear power plant is responsible for adopting whatever measures are needed for safe management and disposal of spent nuclear fuel and radioactive waste deriving from it and for decommissioning and dismantling of the reactor plants after they have been taken out of service. The most important measures are to plan, build and operate the facilities and systems that are needed for this, and to conduct related research and development. The financing of these measures is based on payment of fees to a fund by the licensees, primarily during the period the reactors are in operation, but also later if need be. The details of this financing are regulated in the so called Financing Act (2006:647) with associated Ordinance (2008:715)1. SKB has the task of calculating and compiling the future costs for the four licensees. The future costs are based on SKB's current planning regarding the design of the system and the timetable for its execution. The current design is called the reference design, while the planning around it is called the reference scenario. This report is based on the proposed plan of the activities that has been presented in SKB's RDandD Programme 2007 and the most recent activity plan. The quantity of spent nuclear fuel to be managed in this scenario is based on an operating time of 50 years for each of the Forsmark and Ringhals reactors and 60 years for the Oskarshamn reactors, rounded off to fuel equivalent to 6,000 copper canisters. Preparations are currently being made by SKB for selection of the site for the final repository for nuclear fuel. The goal is that one of the two sites where the site investigations (now almost completed) have been carried out will be chosen. The cost calculations are based on the assumption of Forsmark as the site in the reference scenario. This choice has been for optimal illumination of different cost aspects and must not be regarded as a commitment on the part of SKB. The

    This study used a state-of-the-art planning model called SWITCH for the electric power system to investigate the evolution of the power systems of California and western North America from present-day to 2050 in the context of deep decarbonization of the economy. Researchers concluded that drastic power system carbon emission reductions were feasible by 2050 under a wide range of possible futures. The average cost of power in 2050 would range between $149 to $232 per megawatt hour across scenarios, a 21 to 88 percent increase relative to a business-as-usual scenario, and a 38 to 115 percent increase relative to the present-day cost of power. The power system would need to undergo sweeping change to rapidly decarbonize. Between present-day and 2030 the evolution of the Western Electricity Coordinating Council power system was dominated by implementing aggressive energy efficiency measures, installing renewable energy and gas-fired generation facilities and retiring coal-fired generation. Deploying wind, solar and geothermal power in the 2040 timeframe reduced power system emissions by displacing gas-fired generation. This trend continued for wind and solar in the 2050 timeframe but was accompanied by large amounts of new storage and long-distance high-voltage transmission capacity. Electricity storage was used primarily to move solar energy from the daytime into the night to charge electric vehicles and meet demand from electrified heating. Transmission capacity over the California border increased by 40 - 220 percent by 2050, implying that transmission siting, permitting, and regional cooperation will become increasingly important. California remained a net electricity importer in all scenarios investigated. Wind and solar power were key elements in power system decarbonization in 2050 if no new nuclear capacity was built. The amount of installed gas capacity remained relatively constant between present-day and 2050, although carbon capture and sequestration was

    A working group appointed by the Minister for the Environment has looked at a number of challenges with municipal planning for new onshore wind turbines. The reason was a desire to review the existing planning basis in order to assess the opportunities and constraints found in the current regulations, on which the wind turbine planning is based. The intention has been to look at whether municipalities have the right planning tools to help to ensure the government's objectives for the continued expansion of wind turbines onshore, and whether new planning tools can be identified. In addition, there has been a desire to bring attention to a good planning process with a positive citizen participation and a fact-based information effort, because there often in the context of local and municipal planning emerges local discussions about the proper placement of new wind turbines. With this report the working group make a number of recommendations to the Minister for the Environment. The recommendations deal with proposals for clarification of the rules (the wind turbine directive and the instructions to the directive), proposals for new planning tools, and proposals for new forms of cooperation and information efforts. The review of the current regulations shows that municipalities generally have the tools they need for planning for siting wind turbines, but there is a need for some adjustments and clarifications of the wind turbine directive. No proposed extensive changes in the laws are proposed, but the working group propose a change of the rural zone regulations. (LN)

    In recent years many campaigns and projects have been carried out with the purpose of reducing the energy consumption. Simultaneously a lot of economic and structural changes are taking place in society in general; changes which also affect the size of the electricity consumption. Furthermore, there is a trend towards increased use of wind mills and decentral combined heating and power plants, which affects the electricity load of the local area. It is difficult to identify and separate the effect of each of these attitude-adjusting activities. The project `Development of methods for evaluation of the effect of electricity saving and load levelling measures` focuses on two different methods which, on different levels, can be used to determine the impact of different different activities on the electricity consumption. Both methods are based on mathematical statistics, and they consist of an analysis of historical data and a test campaign which will make it possible to test specific activities in a comparatively small scale. The historical part covers the years 1974 to 1994 and include such variables as: demography, economic factors, climatic conditions, periods of electricity saving campaigns, the start of billing according to time of day tariff etc. The wish to be able to measure the extent of these energy saving and load reducing initiatives resulted in a test campaign which was carried out under very restricted conditions starting in the fall of 1996. If the effect of the test campaign can be measured and as a consequence of this a method can be estimated, it will be possible to place models which can measure the effect of future campaigns. The primary object of the campaign is not the size of the electricity savings of the individual customer, but rather to obtain total savings for the entire group of customers. The test has been structured in a way which makes it possible to perform an analysis of the effect of the campaign by use of analysis of intervention

    Electrical power could be considered as one of the economy propulsion vector of a country, assuming extremely important and strategic role because it makes direct influence to the production capacity. The expansion of electrical energy production could not only be done in a short time because constructions in this area take many years and could require more then a decade depending on the magnitude of them. The national power generation group is constituted mainly by hydro power plants complemented by thermal power plants which use several kinds of fuel which generation cost is high, if compared to hydro power generation, and should be minimized. It is a complex planning issue to supply the future power demand which basically depends on the analysis of two compoundable scenarios: the first one refers to the forecast of future economy growing and in this case, unless unpredictable issues occur such as the recent high economy growing experimented by China, the future demand does not show any surprise and is easy to predict; the second one, has inside the uncertainty because the hydro plants productions depends on the water quantity of rivers which depends on the past and current rainfall regimen. The quantity of rainfall is a stochastic data and follows the rules of probability and this drives to the study of cases and its deployments which are numerous causing difficulties to forecast the future. The planning of the electrical area has to examine the future demand and provide the necessary power generation equipment assuming a certain risk. To have it done, simulation models are used to predict the future, combining the two scenarios cited before, and viewing the results promoted by decision took in a step before. The difficult of this task is caused by the big amount of future alternatives provided by the combinatorial phenomena which require, to process the model, a computer with high processing capacity and specialized and specific methods that can resolve this

    TroenderEnergi AS ga early 2012 NINA commission to propose a limited area of 5-6 k m2 within a previously investigated larger planning area where one could place in 20 to 25 wind turbines with minimal effect on the eagle population on Froeya. Originally the plan was to place 63 wind turbines in the wider area. Using local contacts' knowledge of the breeding population and NINA's experience from studies on Smoela, this was possible, and in addition, NINA has own data about young sea eagles use of the area. The breeding density of eagles within the planning area of Froeya is very high and on par with what it was in the central parts of Smoela before it was developed wind power there. Eight-nine breeding pairs exist within the planning area, and they have a total of 31 known nests. Lowest density of nests found in the area between Skarsvaaagen and Stutvassdalen, and the area between the Melkstadvatnet and Engdalsheia, and in Grasvatnet area to the east. Young eagles from Smoela use the planned area of Froeya widely, but at least in the southern and eastern parts of the planning area. The data suggest that there is a large degree of overlap between good nesting sites and young sea eagle use of the area. The part of the plan area with the lowest nesting density of eagles has the lowest use of young birds, and it is most birds in its second calendar year. The area is used in all seasons, but most of the summer. The area is used at all times of day. It is most traffic in and out of juveniles between Pipertuva and Engdal, through Langdalen towards Tuvnesvatnet and between Vobsjoen and Flatval. Based on the experiences of Smoela, it must be expect that eagles also will be killed at Froeya caused by collisions between eagles and turbines event of a wind power project. By adding a wind power plant as far as possible away from the densest occurrence of nesting eagles, will make the risk less. It is known that there are horned owls in or near the plan area, and it

    This study explores and assesses challenges for the European permitting and planning system with regard to grid development in the North Sea. The following question is discussed: What planning and permitting challenges can influence the realization of an offshore grid in the North Sea? This is answered by referring to the political context of the North Sea and the development of an offshore grid therein. We present the main features of the proposed regulation by the European Commission (COM(2011)658) that will, if it is adapted, impact current grid permitting procedures. Further, key supranational planning tools for offshore grid development are accounted for and the proposed EU measures are discussed with reference to relevant studies on planning and permitting procedures of realizing electricity grids. Finally, the report provides the general findings and conclusions. (Author)

    After the restructuring of the Brazilian power sector during the 1990's a new set of rules and players (regulators, traders, etc.) was introduced. This situation resulted in significantly impacting the distribution companies in terms of market risks and commercial opportunities. Electric power market assessments that provide fundamental information to the system and tariff planning groups can also be used to support the distribution companies in analyzing various questions within the new rules that have been created. These questions include such items as: how much energy should be contracted in the future in the wholesale market?; how much opportunity is available in offering commercial services to the customer?. This work describes the main changes that have occurred due to the restructuring, such as: the privatization process, a wholesale market implementation, rules for energy trading, and planning and regulatory process. The main challenges for distribution companies as a result of these changes are identified, especially focusing on energy trading in retail and wholesale markets. The process of electric power market assessments is presented and describing the accepted methodology used for demand forecasting for distribution companies. Information required by distribution companies in order to deal with the market challenges are specified - e.g. energy trading, market risks and customer relationship. It is concluded there is a need to obtain detailed information about consumers and to develop market forecast for specific time frame. It must take into consideration all the issues around the retail market - the study needs to analyze the basic factors that impact customer consumption. In order to improve the electric market assessment, it has been useful to apply specific models. After reviewing the existing tools for electric power market assessments (analysis and forecast), it has been found that the models that combined methods of end use analysis with

    The purpose of this paper is to analyze the methodology for power consumption projection presented in the Ten-year (2007-2016) Plan of Power Expansion (PDEE 2007/2016) and to propose some questions for discussion. Indeed, bearing in mind the progress achieved in the recent past with respect to the resumption of long term planning in the Brazilian electric power sector, it is pertinent to promote a discussion about the possible limitations of the expansion methodology proposed in PDEE. In short, it is believed that, starting from such a discussion, it could be possible to contribute towards the aim of making the planning process of the Brazilian electric power sector expansion more transparent, more consistent and more participative, consequently bringing a greater convergence of the expectations of the agents of the sector. The main questions raised in this paper about the PDEE's methodology are with respect to the absence of sufficient detail about the interactive adjustment of the several models used to project the consumption, as well as to the lack of information about the models themselves. The general conclusion of this paper is that, in order that the PDEE meets its objective of providing correct signals to all the agents, it is necessary to include more incisively the sector's specialists and the private agents in the methodological discussions, so that no important doubts will remain about the various projections. In our understanding, the success of such an enterprise will depend not only on the disposition of the agents, but on the greater detail and depth that should be previously given to the questions raised in this paper. It is certainly a significant challenge, of a high complexity but of an even higher importance to the electric power sector and to the Brazilian economy. (author)

    Flyvbjerg, Bent; Richardson, Tim

    In this paper we argue that the use of the communicative theory of Jürgen Habermas in planning theory is problematic because it hampers an understanding of how power shapes planning. We posit an alternative approach based on the power analytics of Michel Foucault which focuses on "what is actually...... done", as opposed to Habermas`  focus on "what should be done". We discuss how the Foucauldian stance problematises planning, asking difficult questions about the treatment of legitimacy, rationality, knowledge and spatiality.

    This book presents four contributions to planning research within an integrated framework. James Allen offers a survey of his research in the field of temporal reasoning, and then describes a planning system formalized and implemented directly as an inference process in the temporal logic. Starting from the same logic, Henry Kautz develops the first formal specification of the plan recognition process and develops a powerful family of algorithms for plan recognition in complex situations. Richard Pelavin then extends the temporal logic with model operators that allow the representation to

      分布式发电(distributed generation,DG)接入对农村电网损耗、电压及可靠性有很大影响,为了充分发挥DG接入的经济技术效益,提出了一种多目标分布式电源规划方法。该方法以设备投资成本、系统有功损耗、停电损失及购电费用4个指标最小为目标函数,利用判断矩阵获得各目标函数权重,通过加权将多目标优化转化成单目标优化问题,采用改进遗传算法实现了DG位置及容量的优化配置。为了避免因DG可选布点太多、导致算法计算速度慢的问题,根据配电网损耗、电压及可靠性指标改善效果,提出了一种实用的确定DG候选位置的方法。IEEE33节点系统仿真结果表明,本文提出的DG规划模型和求解方法能够有效提高农村电网的投资效益和性能指标。%Access of DG to rural power network is closely related to the power energy loss, voltage quality and reliability of rural power network. Therefore, the optimal allocation of DG has important significance for economic and safe operation of rural power grid. In order to make full use of DG,a multi-objective planning method of DG in rural power network is presented in this paper, which takes location and capacity of DG as decision variables, the minimums of the equipment investment cost, system power loss, interruption cost and power purchasing cost as objective functions, power flow balances as equality constraints, maximum line current, upper and lower limit of node voltage, and capacity and quantity limit of DG as inequality constraints. The four objectives are graded according to their importance. The power loss directly reflecting the system operation economy is taken as the first grade, the equipment investment cost reflecting the planning scheme economy as the second grade, the reliability reflecting system operation safety as the third grade, and power purchasing cost as the fourth grade. The judgment matrix can be

    Reserches are actively carried on for neural computing which employs neural network. Hopfield-type neural network is attracting attention as a solution mechanism for combinatorial optimization problems. Most of the reports made on the application of Hopfield-type neural network deal only with equality conditions as the constraints for the optimization problems. Adopting auxiliary variables, a method for the solution, by regular Hopfield-type neural networks, of combinatorial optimization problems including inequality constraints was developed. With the switch planning problem as an example, stability analysis of the energy functions was performed, and conditions for the stabilization were clarified although they are partial. To deal with the inequality constraints, special neurons were introduced which converge to intermediate values between 0 and 1. This method was applied to the switch planning problem of the power distribution system. It was made clear that reasonable solution can be obtained by this method. 10 refs., 9 figs., 3 tabs.

    The purpose of the Power-One Aerocapacitor Commercialization Plan is to communicate to members of management and to all employees the overall objectives of the corporation. Power-One, Inc., has participated in a US Federal Government Technology Reinvestment Project (TRP), entitled {open_quotes}Advanced Power Conversion based on the Aerocapacitor{close_quotes}: the project is a group effort, with Lawrence Livermore National Labs, GenCorp/Aerojet, PolyStor Corp. (a start-up company), and Power-One forming the consortium. The expected resulting technology is the {open_quotes}Aerocapacitor{close_quotes}, which possesses much higher performance levels than the usual capacitors on the market today. Power-One hopes to incorporate the Aerocapacitor into some of its products, hence enhancing their performance, as well as market privately-labeled aerocapacitors through its distribution channels. This document describes the details of Power-One`s plan to bring to market and commercialize the Aerocapacitor and Aerocapacitor-based products. This plan was formulated while Power-One was part of the Oerocap project. It has since pulled out of this project. What is presented in this plan is the work which was developed prior to the business decision to terminate this work.

A mathematical model is built in accordance with linear programming method of distribution network. It makes the maximum overall economic efficiency as the objective function, takes reactive power balance and voltage qualification as constraints and combines the optimization of reactive power flow. Through repeatedly using the iterative method after calculating the operating parameters, we obtain reactive power optimization.

    The results indicate that the annual number of dead birds recorded varies, and that an annual average probably is slightly less than two dead white-tailed eagles and four willow ptarmigans as long as 24 turbines are operating in the wind-power plant. The number of dead birds recorded is minimum figures. The total collision rate has not been estimated, however, the terrain where the power plant is located is difficult to search, and thus the habitat bias will be significant. Taking into account removal rate (scavenging bias) and search efficiency of the dog (search bias) it is assumed that the real number of casualties is somewhat higher. Dead birds are particularly found near turbines located at the edge of the power plant. There is insufficient evidence to conclude whether the recorded mortality for the white- tailed eagle is or is not acceptable with regard to short- or long-term population development. As regards the willow ptarmigan population, the data, while not conclusive, in combination with population censuses suggests that the power-plant extension will not be unacceptable for population development. Both for the white-tailed eagle and the willow ptarmigan an increased mortality must be expected when the power plant turbine number is increased.It is important to clarify whether there are established breeding pairs within the planning area, particularly in connection to the planned road access from the south. By building this road a general disturbance increase will take place. Whether the routing of the road will conflict with nest sites of red-listed species like the eagle owl and grey-headed wood- pecker is unknown as the routing not was known when the fieldwork took place during spring/summer 2009. There is, however, more reason to believe that the road might threaten an eagle owl territory than the contrary. The existing data are insufficient to conclude whether the encroachments connected to the road building from the south into the power-plant area

    The paper points out the integration of the power and the gas sector as a way to make feasible the gas importation project from Bolivia and Argentina. It was assessed the struggle between the take-or-pay obligations for the imported gas consumption against the necessity of an efficient and responsible hydroelectric system operation. An interruptible gas market seems the solution to avoid the uneconomic use of gas in the power sector. This will require a development of a quite complex price system, based upon a gas seasonal and spot market. (author). 5 refs, 4 figs, 1 tab

    Full Text Available BACKGROUND: New approaches and tools were needed to support the strategic planning, implementation and management of a Program launched by the Brazilian Government to fund research, development and capacity building on neglected tropical diseases with strong focus on the North, Northeast and Center-West regions of the country where these diseases are prevalent. METHODOLOGY/PRINCIPAL FINDINGS: Based on demographic, epidemiological and burden of disease data, seven diseases were selected by the Ministry of Health as targets of the initiative. Publications on these diseases by Brazilian researchers were retrieved from international databases, analyzed and processed with text-mining tools in order to standardize author- and institution's names and addresses. Co-authorship networks based on these publications were assembled, visualized and analyzed with social network analysis software packages. Network visualization and analysis generated new information, allowing better design and strategic planning of the Program, enabling decision makers to characterize network components by area of work, identify institutions as well as authors playing major roles as central hubs or located at critical network cut-points and readily detect authors or institutions participating in large international scientific collaborating networks. CONCLUSIONS/SIGNIFICANCE: Traditional criteria used to monitor and evaluate research proposals or R&D Programs, such as researchers' productivity and impact factor of scientific publications, are of limited value when addressing research areas of low productivity or involving institutions from endemic regions where human resources are limited. Network analysis was found to generate new and valuable information relevant to the strategic planning, implementation and monitoring of the Program. It afforded a more proactive role of the funding agencies in relation to public health and equity goals, to scientific capacity building

    The primary focus this year was to operate the system with two amplifiers populated with and pumped by eight high power diode arrays. The system was operated for extended run periods which enabled average power testing of components, diagnostics, and controls. These tests were highly successful, with a demonstrated energy level of over 55 joules for 4 cumulative hours at a repetition rate of 10 Hz (average power 0.55 kW). In addition, high average power second harmonic generation was demonstrated, achieving 227 W of 523.5 nm light (22.7 J, 10 Hz, 15 ns, 30 minutes) Plans to achieve higher energy levels and average powers are in progress. The dual amplifier system utilizes a 4-pass optical arrangement. The Yb:S-FAP slabs were mounted in aerodynamic aluminum vane structures to allow turbulent helium gas flow across the faces. Diagnostic packages that monitored beam performance were deployed during operation. The laser experiments involved injecting a seed beam from the front end into the system and making four passes through both amplifiers. Beam performance diagnostics monitored the beam on each pass to assess system parameters such as gain and nearfield intensity profiles. This year, an active mirror and wavefront sensor were procured and demonstrated in an off-line facility. The active mirror technology can correct for low order phase distortions at user specified operating conditions (such as repetition rates different than 10 Hz) and is a complementary technology to the static phase plates used in the system for higher order distortions. A picture of the laser system with amplifier No.2 (foreground) and amplifier No.1 (background) is shown in Fig. 1.0.1.1. The control system and diagnostics were recently enhanced for faster processing and allow remote operation of the system. The growth and fabrication of the Yb:S-FAP slabs constituted another major element of our program objectives. Our goal was to produce at least fourteen 4x6 cm2 crystalline slabs. These

    The principal objective of this paper is to evaluate the potential for self-production of combined heat and power - CHP generation - in the expansion of the Brazilian electric power supply system. The potential was determined by simulating operation of CHP plants in industries which had previously used oil derivates to supply process heat, as well as of plants for service sectors, which had consumed electricity for air conditioning.

Moreover, the model could combine the uncertainties in system parameters expressed as intervals and fuzzy numbers into the optimization process, which would make the planning results more practical. Then the model was applied to a typical e-lectric power system to support energy saving and emission reduction planning of generation side. Desired energy supply, electricity generation, capacity expansion and emission reduction plans with minimized system costs had been generated.

    The results of Demand-Side Management (DSM) energy saving potential in commercial, government and institutional sectors of Oman were presented along with an evaluation of its impact on generation capacity and energy savings. DSM was defined as electricity demand management by methods such as peak clipping, valley filling, load shifting, and strategic conservation. Peak clipping reduces electricity demand during on-peak periods of the day, thus lowering the peak demand that utilities must meet. In contrast, valley filling increases the electrical load during off-peak periods. Load shifting refers to the movement of loads from peak periods to off-peak periods without any shift in energy use. Strategic load growth aims to increase the load in the future, while strategic conservation aims to decrease the load in the future without any shift in demand to another time. The purpose of DSM is to influence the amount or timing of customers' energy use. It has a positive environmental outlook and provides the best solution between load growth and increasing constraints on new and existing generation, transmission and distribution capacity. Resource options for DSM include energy efficiency options, such as energy efficient appliances, lighting, high efficiency heating, ventilating and air conditioning. Other options include load management and tariffs such as time-of-use incentives. The goal of electricity planning is to meet the load forecast with high reliability at a minimum cost. DSM economic energy savings potential is worked out from both the customer point of view and the electric utility's point of view. The study showed that the use of DSM in commercial and government sectors is economically justified from the customer point of view. DSM programs in the government and commercial sectors reduced the energy consumption to 21 and 38 per cent respectively. The discounted payback period of investment in efficient lighting and air-conditioning was between 4

    Based on electromagnetism-like mechanism (ELM) algorithm, a high fault-tolerant method for multi-objective power network planning is proposed. To enhance the performance of ELM algorithm, its global search ability of the basic model is improved by introducing the idea of passive congregation in. The measures such as adaptive weight, adaptive variation and elitist strategy are adopted to improve the convergence of ELM algorithm. For the power network planning in which the generation planning, substation locations and load demand are known, the multi-objective function reflecting economy and reliability index of power network is turned into single objective model to solve the minimum cost of network planning. Applying decimal coding to a 18-bus system, calculation results show that the proposed algorithm can effectively solve such a large-scale combinatorial optimization problem containing discrete variables and improve the overall satisfaction of the planning scheme. Comparison of simulation results from genetic algorithm and basic ELM algorithm show that the improved ELM algorithm possesses obvious advantages in search efficiency and fanlt-tolerance.%提出基于仿电磁学(electromagnetism—like mechanism,ELM)算法的高容错性多目标电网规划方法。为提升算法的性能,引入被动聚集思想对基本模型的全局寻优能力进行了改善。采用自适应权重、自适应变异和精英策略等措施来改善仿电磁学算法的收敛性。针对电源规划、变电站布点和负荷需求均已知的电网规划,将反映电网经济性和可靠性指标的多目标函数转化为求电网规划最小耗费的单目标模型。对一个18节点系统进行了十进制编码,计算结果证明了该算法能有效地解决电网规划这类含离散变量的大规模组合优化问题和提高规划方案的综合满意度。通过与遗传算法、基本ELM的仿真对比,改进的ELM模型在寻优效率和容错性方面具有明显优势。

    Full Text Available In this work, the impact of radiofrequency radiation leakage from microwave ovens and its effect on 802.15.4 ZigBee-compliant wireless sensor networks operating in the 2.4 GHz Industrial Scientific Medical (ISM band is analyzed. By means of a novel radioplanning approach, based on electromagnetic field simulation of a microwave oven and determination of equivalent radiation sources applied to an in-house developed 3D ray launching algorithm, estimation of the microwave oven’s power leakage is obtained for the complete volume of an indoor scenario. The magnitude and the variable nature of the interference is analyzed and the impact in the radio link quality in operating wireless sensors is estimated and compared with radio channel measurements as well as packet measurements. The measurement results reveal the importance of selecting an adequate 802.15.4 channel, as well as the Wireless Sensor Network deployment strategy within this type of environment, in order to optimize energy consumption and increase the overall network performance. The proposed method enables one to estimate potential interference effects in devices operating within the 2.4 GHz band in the complete scenario, prior to wireless sensor network deployment, which can aid in achieving the most optimal network topology.

  2. New power policy

    1997-04-01

    The federal government in India announced in December 1996 its policy for the Indian power sector, including the scope for further private investment. Called the Common Minimum National Action Plan for Power (the Plan), it was announced less than six months after the new government took office in June 1996. The Plan`s draft was formulated after extensive discussion between the federal and state governments, including two meetings with the state chief ministers and consultations between the 13 political parties which form the ruling coalition at the federal level. Not all suggestions found favor, and only those on which there was a broad agreement or consensus were included, hence the Common Minimum Action Plan. The Plan builds on the policies of the previous government, combined with the recent experience and the feedback the government received from various players in the field, including independent power producers (IPP), financial institutions and multilateral institutions. The Plan follows up on the policies already under implementation. It was clear that to get adequate response from private promoters, power sector reforms - structural and operational - were needed. The difficulties faced by IPP`s in project approval will be tackled through simplification of the procedures, delegation of power from federal agencies to state government and better fuel linkage for thermal plants. There is an emphasis on better use of installed capacities and on faster-track projects. Priority will be given to hydropower, though a detailed policy must evolve. The northeast region, with considerable hydropower potential, will be given special attention. The entry of private investment in the power sector will be carried forward allowing participation in transmission and distribution, too.

    Full Text Available El presente trabajo estudia el problema de la planificación de la operación de corto plazo de sistemas de energía termoeléctrica con restricciones ambientales. Las crecientes preocupaciones ambientales para limitar las emisiones de gases con efecto de estufa llevaron a la elaboración del Protocolo de Kyoto, introduciendo nuevas restricciones en la operación de los sistemas de energía termoeléctrica. Las herramientas tradicionales de apoyo a la decisión deben ser adaptadas a esta nueva coyuntura. El problema consiste en la determinación del plan de acoplamiento de las unidades y del perfil de producción mas adecuado para cada unidad térmica acoplada a lo largo del horizonte temporal. Para su solución, se considera un método de optimización basado en programación dinámica y programación no lineal, y se desarrolla un nuevo sistema de apoyo a la decisión en lenguaje Fortran que considera simultáneamente los costos de los combustibles y las emisiones. Se presentan y se discuten resultados de la simulación computacional a un caso prácticoThis paper analyzes the problem of short-term operational planning of thermoelectric power systems with environmental constraints. The growing worldwide environmental concern to limit emission of greenhouse gases led to the Kyoto Protocol, introducing new constraints in the operation of thermoelectric power systems. The traditional tools that aid decision making must be adapted to this new framework. The problem consist of deciding the commitment of the units and the optimal generation profile for each thermal unit committed throughout the time horizon. For its solution, an optimization method based on dynamic programming and non-linear programming is considered, building a new decision support system in Fortran language which simultaneously considers fuel costs and emissions. The results of the computational simulation applied to a practical case are show and discussed

    According to the requirements of the carbon dioxide emission reduction planning and taking full account of the progressive and uncertainty of the development of the current carbon dioxide capture and storage technology (CCS), a model of emission reduction planning in power plants with the goal to minimum general expenses was developed. By introducing technology readiness level factor and considering the future changes in power plants operation parameters, the progressive and uncertainty of the CCS technology were quantified. Emission reduction index of the carbon capture systems was decomposition by the rate of technological progress. An algorithm based on the discrete bacterial colony chemotaxis (DBCC) was used to solve this problem, the optimal allocation and investment strategy of carbon capture systems under different emission reduction scenarios was obtained by the simulation analysis on the practical example. Finally, the impact of different factors on the mitigation costs in different emission reduction scenarios was obtained by sensitivity analysis. The results demonstrate the effectiveness of the model and the optimization algorithm.%根据二氧化碳减排规划的要求,并充分考虑目前二氧化碳捕集和封存(carbon capture and storage,CCS)技术发展的阶段性与不确定性,建立以阶段综合费用最小为目标函数的发电厂减排规划模型。引入技术成熟度因子,并考虑到发电厂运行参数未来的变化,将CCS技术的阶段性与不确定因素进行量化,依据技术进步率对碳捕集系统减排指标进行分解。采用离散细菌群体趋药性算法(discrete bacterial colony chemotaxis,DBCC)进行求解,通过对实际算例的方针分析,得到系统在不同减排场景下的碳捕集系统最优配置方案与碳捕集系统投资策略。最后通过灵敏度分析得到在不同减排场景下各因素对减排成本的影响。结果证明了所提模型以及

  1. Language Planning and Planned Languages: How Can Planned Languages Inform Language Planning?

    Directory of Open Access Journals (Sweden)

    Humphrey Tonkin

    2015-04-01

    Full Text Available The field of language planning (LP has largely ignored planned languages. Of classic descriptions of LP processes, only Tauli (preceded by Wüster suggests that planned languages (what Wüster calls Plansprache might bear on LP theory and practice. If LP aims "to modify the linguistic behaviour of some community for some reason," as Kaplan and Baldauf put it, creating a language de novo is little different. Language policy and planning are increasingly seen as more local and less official, and occasionally more international and cosmopolitan. Zamenhof's work on Esperanto provides extensive material, little studied, documenting the formation of the language and linking it particularly to issues of supranational LP. Defining LP decision-making, Kaplan & Baldauf begin with context and target population. Zamenhof's Esperanto came shortly before Ben-Yehuda's revived Hebrew. His target community was (mostly the world's educated elite; Ben-Yehuda's was worldwide Jewry. Both planners were driven not by linguistic interest but by sociopolitical ideology rooted in reaction to anti-Semitism and imbued with the idea of progress. Their territories had no boundaries, but were not imaginary. Function mattered as much as form (Haugen's terms, status as much as corpus. For Zamenhof, status planning involved emphasis on Esperanto's ownership by its community - a collective planning process embracing all speakers (cf. Hebrew. Corpus planning included a standardized European semantics, lexical selectivity based not simply on standardization but on representation, and the development of written, and literary, style. Esperanto was successful as linguistic system and community language, less as generally accepted lingua franca. Its terminology development and language cultivation offers a model for language revival, but Zamenhof's somewhat limited analysis of language economy left him unprepared to deal with language as power.

En la formulación del problema se consideran múltiples embalses en cascada y el efecto que la variación de la altura del salto tiene sobre la eficiencia de la operación. El efecto de la variación de la altura del salto, siendo no lineal, junto con la configuración hidráulica en cascada, vuelve el problema más complejo y de gran dimensión. Para su resolución, se considera un método de optimización basado en programación no-lineal. Los resultados se comparan con el método corrientemente utilizado, basado en la programación lineal. Los resultados de la simulación computacional demuestran que la programación no lineal es el método de optimización más adecuado.A study was made on the problem of short-term operational planning for hydroelectric power systems. Consideration was given to multiple reservoirs in a cascade and the effect that the variation of the head has in the operating efficiency. This non-linear effect coupled with the cascaded hydro configuration tends to produce a complex problem of large dimension. For its resolution an optimization method based on non-linear programming is considered. The results are compared with the method currently used based on linear programming. The results of the computational simulation show that the non-linear programming is the most suitable optimization method.

    This work presents an approach for the planning of transmission systems by employing mixed--integer linear programming to obtain a cost and operating characteristics optimized system. The voltage loop equations are written in a modified form, so that, at the end of the analysis, the model behaves as a DC power flow, with the help of the two Kirchhoff`s laws, exempting the need of interaction with an external power flow program for analysis of the line loading. The model considers the occurrence of contingencies, so that the final result is a network robust to the most severe contingencies. This whole technique is adapted to the regional electric power transmission subsystems. (author) 9 refs., 4 figs.

    As part of the U.S. Department of Energy’s Light Water Reactor Sustainability Program, the Digital Architecture (DA) Project focuses on providing a model that nuclear utilities can refer to when planning deployment of advanced technologies. The digital architecture planning model (DAPM) is the methodology for mapping power plant operational and support activities into a DA that unifies all data sources needed by the utilities to operate their plants. The DA is defined as a collection of information technology capabilities needed to support and integrate a wide spectrum of real-time digital capabilities for performance improvements of nuclear power plants. DA can be thought of as integration of the separate instrumentation and control and information systems already in place in nuclear power plants, which are brought together for the purpose of creating new levels of automation in plant work activities. A major objective in DAPM development was to survey all key areas that needed to be reviewed in order for a utility to make knowledgeable decisions regarding needs and plans to implement a DA at the plant. The development was done in two steps. First, researchers surveyed the nuclear industry in order to learn their near-term plans for adopting new advanced capabilities and implementing a network (i.e., wireless and wire) infrastructure throughout the plant, including the power block. Secondly, a literature review covering regulatory documents, industry standards, and technical research reports and articles was conducted. The objective of the review was to identify key areas to be covered by the DAPM, which included the following: 1. The need for a DA and its benefits to the plant 2. Resources required to implement the DA 3. Challenges that need to be addressed and resolved to implement the DA 4. Roles and responsibilities of the DA implementation plan. The DAPM was developed based on results from the survey and the literature review. Model development, including

    Full Text Available Most power systems in underdeveloped and developing countries are based on conventional power plants, mainly "slow-response" thermal power plants and a certain number of hydro power plants; characterized by inflexible generating portfolios and traditionally designed to meet own electricity needs. Taking into account operational capabilities of conventional power systems, their development planning will face problems with integration of notable amounts of installed capacities in wind power plants (WPP. This is what highlights the purpose of this work and in that sense, here, possible variations of simulated output power from WPP in the 10 minute and hourly time interval, which need to be balanced, are investigated, presented and discussed. Comparative calculations for the amount of installed power in WPP that can be integrated into a certain power system, according to available secondary balancing power amounts, in case of concentrated and dispersed future WPP are given. The stated has been done using a part of the power system of Bosnia and Herzegovina. In the considered example, by planned geographically distributed WPP construction, even up to cca. 74% more in installed power of WPP can be integrated into the power system than in case of geographically concentrated WPP construction, for the same available amount of (secondary balancing power. These calculations have shown a significant benefit of planned, geographically distributed WPP construction, as an important recommendation for the development planning of conventional power systems, with limited balancing options.

    There are numerous documented cases of extraction of fluids from the ground causing surface subsidence. The cases include groundwater, oil and gas, as well as geothermal fluid withdrawal. A recent comprehensive review of all types of man-induced land subsidence was published by the Geological Survey of America. At the early stages of a geothermal power development project it is standard practice in most countries for an environmental impact report to be required. The possibility of geothermal subsidence has to be addressed, and usually it falls on the geophysicists and/or geologists to make some predictions. The advice given is vital for planning the power plant location and the borefield pipe and drain layout. It is not so much the vertical settlement that occurs with subsidence but the accompanying horizontal ground strains that can do the most damage to any man-made structure.

    1981-01-01

    The Venture Evaluation and Review Technique (VERT) is a computerized, mathematically oriented network-based simulation technique designed to analyze risk existing in three parameters of most concern to managers in new projects or ventures--time, cost, and performance. As such, the VERT technique is more powerful than techniques such as GERT, which are basically time and cost oriented. VERT has been successfully utilized to assess the risks involved in new ventures and projects, in the estimation of future capital requirements, in control monitoring, and in the overall evaluation of ongoing projects, programs, and systems. It has been helpful to management in cases where there is a requirement to make decisions with incomplete or inadequate information about the alternatives. An example describing the application of VERT to an operational planning problem--the evaluation of electric power generating methods--is illustrated.

Herein, the power outputs of wind farm were sampled, and the uncertain multi-objective transmission network planning model was transformed into a solvable deterministic model. Compared with other algorithms of probabilistic power flow, such as algorithms based on Monte Carlo simulation and analytical method, the presented method needs less input information, and can easily combine with the multi-objective transmission network planning model. Besides, this method also has the advantages of low computational amount, high accuracy and wide generalization. Therefore, the presented method is effective to deal with the uncertainty of wind power in transmission network planning. Finally, the IEEE 24-bus test system was adopted to verify the presented method and algorithm.

  19. On optimization of power production

    Energy Technology Data Exchange (ETDEWEB)

    Feltenmark, S.

    1997-01-01

    Short-term optimization of power production is treated. It concerns the problem of determining a production schedule for a power system, which minimizes the total cost of production, while satisfying various constraints. The thesis consists of an introductory chapter, four chapters that each concerns a specific problem area (economic dispatch, unit commitment, hydro power planning and cogeneration optimization), plus a chapter with relevant theory. The emphasis of the thesis is on the mathematical structures that arise in problems in this field, and how to exploit them algorithmically. A recurring theme is convexification, either implicit, by dualization, or explicit, as in our approach to hydro power optimization. 134 refs

  20. Power outages, power externalities, and baby booms.

    Science.gov (United States)

    Burlando, Alfredo

    2014-08-01

    Determining whether power outages have significant fertility effects is an important policy question in developing countries, where blackouts are common and modern forms of family planning are scarce. Using birth records from Zanzibar, this study shows that a month-long blackout in 2008 caused a significant increase in the number of births 8 to 10 months later. The increase was similar across villages that had electricity, regardless of the level of electrification; villages with no electricity connections saw no changes in birth numbers. The large fertility increase in communities with very low levels of electricity suggests that the outage affected the fertility of households not connected to the grid through some spillover effect. Whether the baby boom is likely to translate to a permanent increase in the population remains unclear, but this article highlights an important hidden consequence of power instability in developing countries. It also suggests that electricity imposes significant externality effects on rural populations that have little exposure to it.

    The Puget Sound Area Electric Reliability Plan Draft Environmental Impact Statement (DEIS) identifies the alternatives for solving a power system problem in the Puget Sound area. This Plan is undertaken by Bonneville Power Administration (BPA), Puget Sound Power Light, Seattle City Light, Snohomish Public Utility District No. 1 (PUD), and Tacoma Public Utilities. The Plan consists of potential actions in Puget Sound and other areas in the State of Washington. A specific need exists in the Puget Sound area for balance between east-west transmission capacity and the increasing demand to import power generated east of the Cascades. At certain times of the year, there is more demand for power than the electric system can supply in the Puget Sound area. This high demand, called peak demand, occurs during the winter months when unusually cold weather increases electricity use for heating. The existing power system can supply enough power if no emergencies occur. However, during emergencies, the system will not operate properly. As demand grows, the system becomes more strained. To meet demand, the rate of growth of demand must be reduced or the ability to serve the demand must be increased, or both. The plan to balance Puget Sound's power demand and supply has these purposes: The plan should define a set of actions that would accommodate ten years of load growth (1994--2003). Federal and State environmental quality requirements should be met. The plan should be consistent with the plans of the Northwest Power Planning Council. The plan should serve as a consensus guideline for coordinated utility action. The plan should be flexible to accommodate uncertainties and differing utility needs. The plan should balance environmental impacts and economic costs. The plan should provide electric system reliability consistent with customer expectations. 29 figs., 24 tabs.

As we know, it can provide electricity anywhere in the world from the Earth's orbit, mostly Indonesia an equator country. We have to perform case studies of various countries to understand their benefits and disadvantages provided by the SSP, because each country has much different condition on energy from other countries. We are at the moment starting the international collaboration between Indonesia and Japan to carry out the case study for Indonesia. We understand that in Indonesia itself each province has much different micro-climate between one province compared to the other. In Japan, METI (Ministry of Economy, Trade and Industry) has already organized a committee to investigate the feasibility of Space Solar Power and to make a plan to launch a space demonstration of the SPS. While, Indonesia is quickly developing economy and increasing their energy demand. We are investigating the detailed energy conditions of Indonesia, the benefits and disadvantages of the Space Solar Power for Indonesia.

    Longitudinal study designs are indispensable for investigating age-related functional change. There now are well-established methods for addressing missing data in longitudinal studies. Modern missing data methods not only minimize most problems associated with missing data (e.g., loss of power and biased parameter estimates), but also have valuable new applications such as research designs that use modern missing data methods to plan missing data purposefully. This article describes two state-of-the-art statistical methodologies for addressing missing data in longitudinal research: growth curve analysis and statistical measurement models. How the purposeful planning of missing data in research designs can reduce subject burden, improve data quality and statistical power, and manage costs is then described.

    The publication shows that the dena study has serious shortcomings, both in its methodology and in its assumption of energy industry boundary conditions. The best options for development of the power plant park in consideration of climate protection, low price, reliability of supply and high availability cannot be derived using simple time-dependent and static methods. Effective analyses must comprise a simultaneous analysis of power and energy balances, in consideration of the need for power reserves in a dynamic context. Further, market mechanisms must be considered that take account of the neighbouring European markets and the effective mechanisms of deregulated electricity markets. Not least, the political boundary conditions must be considered, e.g. greenhouse gas emissions and financial incentives for renewable energy sources. Even though such analyses are highly complex, they are indispensable if erroneous conclusions are to be prevented.

  12. Concentrating solar thermal power.

    Müller-Steinhagen, Hans

    2013-08-13

    In addition to wind and photovoltaic power, concentrating solar thermal power (CSP) will make a major contribution to electricity provision from renewable energies. Drawing on almost 30 years of operational experience in the multi-megawatt range, CSP is now a proven technology with a reliable cost and performance record. In conjunction with thermal energy storage, electricity can be provided according to demand. To date, solar thermal power plants with a total capacity of 1.3 GW are in operation worldwide, with an additional 2.3 GW under construction and 31.7 GW in advanced planning stage. Depending on the concentration factors, temperatures up to 1000°C can be reached to produce saturated or superheated steam for steam turbine cycles or compressed hot gas for gas turbine cycles. The heat rejected from these thermodynamic cycles can be used for sea water desalination, process heat and centralized provision of chilled water. While electricity generation from CSP plants is still more expensive than from wind turbines or photovoltaic panels, its independence from fluctuations and daily variation of wind speed and solar radiation provides it with a higher value. To become competitive with mid-load electricity from conventional power plants within the next 10-15 years, mass production of components, increased plant size and planning/operating experience will be accompanied by technological innovations. On 30 October 2009, a number of major industrial companies joined forces to establish the so-called DESERTEC Industry Initiative, which aims at providing by 2050 15 per cent of European electricity from renewable energy sources in North Africa, while at the same time securing energy, water, income and employment for this region. Solar thermal power plants are in the heart of this concept.

  13. OPPORTUNITIES IN SMR EMERGENCY PLANNING

    Energy Technology Data Exchange (ETDEWEB)

    Moe, Wayne

    2014-06-01

    This paper discusses the results of a cost/benefit-oriented assessment related to sizing of the emergency planning zones (EPZs) for advanced, small modular reactors (SMRs). An appropriately sized EPZ could result in significant cost savings for SMR licensees. Papers published by the U.S. Nuclear Regulatory Commission and other organizations discuss the applicability of current emergency preparedness regulatory requirements to SMRs, including determining an appropriate EPZ size. Both the NRC and the industry recognize that a methodology should be developed for determining appropriate EPZ sizing for SMRs. Relative costs for smaller EPZs envisioned for SMRs have been assessed qualitatively as discussed in this paper. Building off the foundation provided in the earlier papers, this paper provides a quantitative cost/benefit-oriented assessment of offsite emergency planning costs for EPZ sizes that may be justified for SMRs as compared to costs typically incurred for the current fleet of U.S. nuclear power plants. This assessment determined that a licensee utilizing a smaller EPZ could realize significant savings in offsite emergency planning costs over the nominal 40-year lifetime for an SMR. This cost/benefit-oriented assessment suggests that a reduction of the plume exposure pathway EPZ from 10 miles to the site boundary could reduce offsite emergency planning related costs by more than 90% over the 40 year life of a typical single unit nuclear power plant.

    PowerPal micro-hydro equipment was developed in Vietnam by Asian Phoenix Resources Ltd. of Victoria, BC; a company who aims to help disadvantaged people in less developed countries by making renewable energy devices available to them. The idea for the micro-hydro system was conceived after mineral exploration parties in Vietnam noted that large numbers of poor quality propeller turbines were being used to supply AC power to individual homes. A plan was developed to improve the quality and reliability of low head turbines with better castings, magnets, superior bearings and electronic load controllers. Funding for the program was initially difficult to obtain. However, PowerPal micro-hydro equipment eventually came to the attention of the World Bank as well as other government and non-governmental organizations. Financing for the purchase and installation of larger numbers of units has now been achieved, and missionary groups in various parts of the world have ordered units. European markets have also opened up, and distributors of the micro-hydro equipment have been appointed in various countries. Sales are now strong in Central America, South America, the Caribbean, Australasia, Oceania, Africa and Europe. It was concluded that the surge of interest has coincided with a steep upturn in oil prices. 8 figs.

    Science.gov (United States)

    Titus, Nathan A.

    1992-12-01

    The performance of an automation or robotic device can be measured in terms of its power efficiency. Screw theory is used to mathematically define the task instantaneously with two screws. The task wrench defines the effect of the device on its environment, and the task twist describes the motion of the device. The tasks can be separated into three task types: kinetic, manipulative, and reactive. Efficiency metrics are developed for each task type. The output power is strictly a function of the task screws, while device input power is shown to be a function of the task, the device Jacobian, and the actuator type. Expressions for input power are developed for two common types of actuators, DC servometers and hydraulic actuators. Simple examples are used to illustrate how power analysis can be used for task/workspace planning, actuator selection, device configuration design, and redundancy resolution.

    Science.gov (United States)

    2014-05-01

    There are several types of planning processes and plans, including strategic, operational, tactical, and contingency. For this document, operational planning includes tactical planning. This chapter examines the strategic planning process and includes an introduction into disaster response plans. "A strategic plan is an outline of steps designed with the goals of the entire organisation as a whole in mind, rather than with the goals of specific divisions or departments". Strategic planning includes all measures taken to provide a broad picture of what must be achieved and in which order, including how to organise a system capable of achieving the overall goals. Strategic planning often is done pre-event, based on previous experience and expertise. The strategic planning for disasters converts needs into a strategic plan of action. Strategic plans detail the goals that must be achieved. The process of converting needs into plans has been deconstructed into its components and includes consideration of: (1) disaster response plans; (2) interventions underway or planned; (3) available resources; (4) current status vs. pre-event status; (5) history and experience of the planners; and (6) access to the affected population. These factors are tempered by the local: (a) geography; (b) climate; (c) culture; (d) safety; and (e) practicality. The planning process consumes resources (costs). All plans must be adapted to the actual conditions--things never happen exactly as planned.

    Labarbe, Rudi; Janssens, Guillaume; Sterpin, Edmond

    2016-09-01

    In proton therapy, quantification of the proton range uncertainty is important to achieve dose distribution compliance. The promising accuracy of prompt gamma imaging (PGI) suggests the development of a mathematical framework using the range measurements to convert population based estimates of uncertainties into patient specific estimates with the purpose of plan adaptation. We present here such framework using Bayesian inference. The sources of uncertainty were modeled by three parameters: setup bias m, random setup precision r and water equivalent path length bias u. The evolution of the expectation values E(m), E(r) and E(u) during the treatment was simulated. The expectation values converged towards the true simulation parameters after 5 and 10 fractions, for E(m) and E(u), respectively. E(r) settle on a constant value slightly lower than the true value after 10 fractions. In conclusion, the simulation showed that there is enough information in the frequency distribution of the range errors measured by PGI to estimate the expectation values and the confidence interval of the model parameters by Bayesian inference. The updated model parameters were used to compute patient specific lateral and local distal margins for adaptive re-planning.

    2012-01-01

    Communication satellites are a $144 billion industry. Is there any space-based industry that could possibly beat that market? 'Solar Power Satellites' shows why and how the space satellite industry will soon begin expanding its market from relaying signals to Earth to generating energy in space and delivering it to the ground as electricity. In all industrialized nations, energy demand is growing exponentially. In the developing world, the need for energy is as basic as food and water. The Sun's energy is available everywhere, and it is non-polluting. As business plans demonstrate its technical feasibility, commercial potential, and environmental acceptability, every country on Earth will look to space for the power it needs.

    In this work, are presented the technical and economic elements of the international experience for the installation of IGCC power plants in the petroleum refinement and the lessons for Mexico in the installation of this technology in PEMEX Refinacion are analyzed. The construction of IGCC power plants in the petroleum refinement has grown 14.3 % at worldwide level as of 1996, in which there was already an installed capacity of 160 MW. At the end of 2003 an installed capacity of 2,500 MW was reached. The growth in the installation of IGCC power plants fundamentally appears in Europe, being Italy and Spain leader countries in the construction of this technology in the petroleum refinement. However, countries like Holland, Japan, Singapore and the United States count on IGCC power plants for electricity and hydrogen generation, which take advantage of low value fuels such as vacuum tower residues, petroleum coke, asphalt, liquid fuels, among others. In Mexico, the installation IGCC power plants in the petroleum refinement is null, nevertheless Petroleos Mexicanos counts with the approval of the government for the installation of cogeneration power plants in its facilities. This approval would allow PEMEX to carry out projects for the installation IGCC power plants, specifically in PEMEX Refinacion, for the generation of electricity and hydrogen from the advantage of heavy residues of low economic value. The opportunity that the installation IGCC power plants in the petroleum refinement offers is directed towards the commercialization of the electricity and hydrogen, which would impel PEMEX Refinacion to enter the competition of the electrical market in Mexico.

    This paper presents an operational policy for the mid term hydrothermal scheduling of the Brazilian Interconnected Power System (BIPS) based on the individual representation of the hydro and thermo power plants, the detailed representation of the plants' features and the indirect representation of the inflow stochasticity through a forecasting model. These characteristics differs the operational policy which is in use nowadays in BIPS, which is based on four interconnected subsystems represented by composite reservoirs. Several case studies are presented to evaluate the performance of the operational policy, from the simple case with a single hydro plant system to the complete case of the whole BIPS under real conditions. For this last case an operational adjustment procedure was implemented to assure the market attendance considering interchange constraints between the subsystems. (author)

    2015-01-01

    We introduce a novel communication strategy for DC Micro Grids (MGs), termed power talk, in which the devices communicate by modulating the power levels in the DC bus. The information is transmitted by varying the parameters that the MG units use to control the level of the common bus voltage......, while it is received by processing the bus measurements that units perform. This implies that the communication does not require a dedicated modem, but instead it is piggybacked on top of the power electronics. The communication is challenged by the random fluctuations of the voltage level due...

Each VSC transmits information by changing the control parameters, and receives information by observing the local...... output power. By using common coding schemes, which transform the DC MGs in some familiar communication channels, some important communication challenges can be addressed, such as random load variations and VSCs switching, as it do not need a separate communication channel.

    The High Average Power Laser Program (HAPL) is a multi-institutional, coordinated effort to develop a high-energy, repetitively pulsed laser system for Inertial Fusion Energy and other DOE and DOD applications. This program is building a laser-fusion energy base to complement the laser-fusion science developed by DOE Defense programs over the past 25 years. The primary institutions responsible for overseeing and coordinating the research activities are the Naval Research Laboratory (NRL) and LLNL. The current LLNL proposal is a companion proposal to that submitted by NRL, for which the driver development element is focused on the krypton fluoride excimer laser option. Aside from the driver development aspect, the NRL and LLNL companion proposals pursue complementary activities with the associated rep-rated laser technologies relating to target fabrication, target injection, final optics, fusion chamber, materials and power plant economics. This report requests continued funding in FY02 to support LLNL in its program to build a 1kW, 100J, diode-pumped, crystalline laser. In addition, research in high gain laser target design, fusion chamber issues and survivability of the final optic element will be pursued. These technologies are crucial to the feasibility of inertial fusion energy power plants and also have relevance in rep-rated stewardship experiments.

    The Autonomous Power System (APS) project at NASA Lewis Research Center is designed to demonstrate the abilities of integrated intelligent diagnosis, control, and scheduling techniques to space power distribution hardware. Knowledge-based software provides a robust method of control for highly complex space-based power systems that conventional methods do not allow. The project consists of three elements: the Autonomous Power Expert System (APEX) for fault diagnosis and control, the Autonomous Intelligent Power Scheduler (AIPS) to determine system configuration, and power hardware (Brassboard) to simulate a space based power system. The operation of the Autonomous Power System as a whole is described and the responsibilities of the three elements - APEX, AIPS, and Brassboard - are characterized. A discussion of the methodologies used in each element is provided. Future plans are discussed for the growth of the Autonomous Power System.

  6. Wind power integration into the automatic generation control of power systems with large-scale wind power

    Full Text Available Transmission system operators have an increased interest in the active participation of wind power plants (WPP in the power balance control of power systems with large wind power penetration. The emphasis in this study is on the integration of WPPs into the automatic generation control (AGC of the power system. The present paper proposes a coordinated control strategy for the AGC between combined heat and power plants (CHPs and WPPs to enhance the security and the reliability of a power system operation in the case of a large wind power penetration. The proposed strategy, described and exemplified for the future Danish power system, takes the hour-ahead regulating power plan for generation and power exchange with neighbouring power systems into account. The performance of the proposed strategy for coordinated secondary control is assessed and discussed by means of simulations for different possible future scenarios, when wind power production in the power system is high and conventional production from CHPs is at a minimum level. The investigation results of the proposed control strategy have shown that the WPPs can actively help the AGC, and reduce the real-time power imbalance in the power system, by down regulating their production when CHPs are unable to provide the required response.

  7. Planning to Plan-Integrating Control Flow

    Institute of Scientific and Technical Information of China (English)

    2003-01-01

    In many planning situations, computation itself becomes a resource to be planned and scheduled. We model such computational resources as conventional resources which are used by control-flow actions, e.g., to direct the planning process. Control-flow actions and conventional actions are planned/scheduled in an integrated way and can interact with each other. Control-flow actions are then executed by the planning engine itself. The approach is illustrated by examples, e.g., for hierarchical planning, in which tasks that are temporally still far away impose only rough constraints on the current schedule, and control-flow tasks ensure that these tasks are refined as they approach the current time. Using the same mechanism, anytime algorithms can change appropriate search methods or parameters over time, and problems like scheduling critical time-outs for garbage collection can be made part of the planning itself.

    Galster, Kjeld

    Power Preservation (Abstract) In the 17th century, just as today, coalitions needed ‘lead nations’. This was assumed to be a power with great military and economic potentials, and Denmark endeavoured to act as such a leader in the Thirty Years War from 1626 to 28. The results were not encouraging...... in the military field and they were disastrous as far as fiscal matters were concerned. Sweden took over the leadership of the protestant side and she took over Denmark’s place amongst the great powers of the Baltic Region. From that time onwards, Danish influence and options on the international stage gradually...... declined. Thus, Denmark of the 17th century is not to be counted amongst the great powers, but since Christian V’s accession to the throne in 1670 Denmark-Norway has developed into one of Europe’s most highly militarised states. Apart from a permanently combat ready navy, the country maintains a standing...

    The High Average Power Laser Program (HAPL) is a multi-institutional, synergistic effort to develop inertial fusion energy (IFE). This program is building a physics and technology base to complement the laser-fusion science being pursued by DOE Defense programs in support of Stockpile Stewardship. The primary institutions responsible for overseeing and coordinating the research activities are the Naval Research Laboratory (NRL) and Lawrence Livermore National Laboratory (LLNL). The current LLNL proposal is a companion document to the one submitted by NRL, for which the driver development element is focused on the krypton fluoride excimer laser option. The NRL and LLNL proposals also jointly pursue complementary activities with the associated rep-rated laser technologies relating to target fabrication, target injection, final optics, fusion chamber, target physics, materials and power plant economics. This proposal requests continued funding in FY03 to support LLNL in its program to build a 1 kW, 100 J, diode-pumped, crystalline laser, as well as research into high gain fusion target design, fusion chamber issues, and survivability of the final optic element. These technologies are crucial to the feasibility of inertial fusion energy power plants and also have relevance in rep-rated stewardship experiments. The HAPL Program pursues technologies needed for laser-driven IFE. System level considerations indicate that a rep-rated laser technology will be needed, operating at 5-10 Hz. Since a total energy of {approx}2 MJ will ultimately be required to achieve suitable target gain with direct drive targets, the architecture must be scaleable. The Mercury Laser is intended to offer such an architecture. Mercury is a solid state laser that incorporates diodes, crystals and gas cooling technologies.

    Recent work has shown that Dynamic Epistemic Logic (DEL) offers a solid foundation for automated planning under partial observability and non-determinism. Under such circumstances, a plan must branch if it is to guarantee achieving the goal under all contingencies (strong planning). Without...... branching, plans can offer only the possibility of achieving the goal (weak planning). We show how to formulate planning in uncertain domains using DEL and give a language of conditional plans. Translating this language to standard DEL gives verification of both strong and weak plans via model checking....... In addition to plan verification, we provide a tableau-inspired algorithm for synthesising plans, and show this algorithm to be terminating, sound and complete....

    Based on the dynamic programming, the electromagnetism-like mechanism algorithm is applied to multi-objective dynamic planning. It eliminates the over-dependence of the total force vector on the distance, and by drawing lessons from passive congregation thought, enhances the anti-disturbance and global optimization ability of the population mobility model. In the sectors of weight, local search, and mutation, the adaptive strategy is used to improve the searching speed, and the elitist strategy is used to improve the convergence efficiency. By adding the Markov constraints, the re-dismantling of lines is avoided. Using the weighted method and penalty function method, multiple objectives describing the grid economy, reliability, and static N-1 security are measured in a unified manner to reflect the overall satisfaction of the plan. Applying decimal coding to 19-bus and 46-bus system, the results show that the algorithm can effectively solve the multi-objective dynamic grid planning. Compared with the genetic algorithm, the improved ELM has obvious advantages in searching efficiency and fault-tolerance.%基于动态规划思想,提出将类电磁机制(Electromagnetism-Like Mechanism,ELM)算法应用于多目标动态电网规划。消除了总矢量力对距离的过分倚重,并借鉴被动聚集思想,提升了种群移动模型的抗扰动和全局寻优能力。在权重、局部搜索、变异等环节均采用自适应策略来改善寻优速度,利用精英策略提高收敛效率。通过增设的马尔科夫性约束,避免了架线复拆。采用加权法和罚函数法,将描述电网经济性、可靠性、静态 N1安全的多目标进行统一度量,以体现规划方案的综合满意度。通过对19节点、46节点系统进行十进制编码测试,结果验证了该算法能有效地解决多目标动态电网规划。与遗传算法相比,改进的ELM在寻优效率和容错性方面具有明显优势。

    Inspired by the growing attention to the politics of comedy in the United States and elsewhere, this article asks what it would mean to think critically about relations of power mobilized through cheerfulness, humor, and laughter. The article shows that existing answers to this question are tainted...... by skepticism about the enduring contributions of comic acts, and it then goes on to suggest that we turn to an alternative trajectory in democratic theory, one that encourages us to focus on the empowering and pluralizing potential embedded in what I name “comic power.” The wager is that attention...... to the potential embedded in this power can give us new traction on the conditions of democracy more broadly understood. To show this, the article draws on two rarely paired resources—Spinoza’s philosophy of immanence and Dave Chappelle’s critique of racial discrimination—placing both of them in conversation...

    NASA plans to orbit a permanently manned space station in the late 1990s, which requires development and assembly of a photovoltaic (PV) power source system to supply up to 75 kW of electrical power average during the orbital period. The electrical power requirements are to be met by a combination of PV source, storage, and control elements for the sun and eclipse periods. The authors discuss the application of power electronics and controls to manage the generation, storage, and distribution of power to meet the station loads, as well as the computer models used for analysis and simulation of the PV power system. The requirements for power source integrated controls to adjust storage charge power during the insolation period current limiting, breaker interrupt current values, and the electrical fault protection approach are defined. Based on these requirements, operating concepts have been defined which then become drivers for specific system and element design.

    Meetings are held by leaders for many purposes, including conveying information, raising morale, asking for opinions, brain storming, making people part of the problem-solving process, building trust, getting to a consensus, and making decisions. However, many meetings waste time, some undermine the leader's power, and some decrease morale. Part I of this series of articles gives some tips on basic planning for decision-making meetings. Part II of this series of articles analyzes selected components of decision-making meetings. Part III of this series will be on how the chairperson keeps decision-making meetings on track to make them efficient and productive.

    The book contains a summary of our knowledge of power semiconductor structures. It presents first a short historic introduction (Chap. I) as well as a brief selection of facts from solid state physics, in particular those related to power semiconductors (Chap. 2). The book deals with diode structures in Chap. 3. In addition to fundamental facts in pn-junction theory, the book covers mainly the important processes of power structures. It describes the emitter efficiency and function of microleaks (shunts). the p +p and n + n junctions, and in particular the recent theory of the pin, pvn and p1tn junctions, whose role appears to be decisive for the forward mode not only of diode structures but also of more complex ones. For power diode structures the reverse mode is the decisive factor in pn-junction breakdown theory. The presentation given here uses engineering features (the multiplication factor M and the experimentally detected laws for the volume and surface of crystals), which condenses the presentation an...

  17. Power branding

    1998-12-31

    For most of its century-long history, electricity was a natural monopoly, due in part to the excessive cost of the necessary infrastructure. In the past decade, however, politics have pushed the industry toward competition and consumer choice. At the same time, technology has been developed that allows consumers to choose their electricity supplier and to track the flow of power through the various grids and lines. In her new book, Power Branding, author and industry expert Ann Chambers examines marketing and branding of electricity -- what it is, how it`s done, what its benefits are for electric utilities, marketers, and even natural gas companies allied with the utilities. She surveys industry leaders who have already taken a dive into the ocean of marketing and offers lessons drawn from their experiences. She also takes a look at other formerly regulated industries -- airlines, telephone, natural gas -- and describes how their rebirth as free-market industries may affect the course of the electric utility industry`s experience. The contents include: Introduction; Basics of branding: Brand image; Value-added services; Southern Company; Duke Energy; UtiliCorp/EnergyOne/Aquila--big and brand; Engage energy; Florida Power and Light Co.; Enron; Convergence; Lessons from the natural gas industry; Lessons from other industries; Conclusion; Resources; Glossary of branding, marketing and Btu convergence; and Major federal legislation affecting the electric power industry.
