  4. Philippines revises power plans

    Energy Technology Data Exchange (ETDEWEB)

    Hayes, D.


    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.

    Full text: Wind energy is a relative new industry in South Africa. This provides South Africans with the opportunity to ensure that wind farms are placed in areas that are of low sensitivity to birds. With this in mind two environmental NGOs, BirdLife South Africa and the Endangered Wildlife Trust, designed an Avian Wind Sensitivity Map to provide guidance to the wind farm industry about the location of wind turbines. The map is the first of its kind in Africa. The purpose of the map is to provide an indication of the geographic areas in South Africa where the possible establishment of wind farms might have a negative impact on birds. Such a map will identify areas of bird sensitivity, i.e. sites where threatened, endemic and vulnerable bird species occur. The map was designed using a variety of data sources, specifically data acquired through citizen science projects - such as the Southern African Bird Atlas Project 2 and the Coordinated Waterbird Counts Project. The data were analysed using data priority scores based on the conservation concern of each species as well as the risk associated with a species to fly into wind turbines and associated infrastructures. The formal protection status of a geographic area was also taken into account. Extensive use was made of GIS tools to collate, analyse and present the data. A number of African countries are considering establishing wind farms. The lessons learnt during the design process can be used by other African countries as the basis for similar maps which can serve as a mitigation measure against the loss of vulnerable species.

  7. Nuclear power programme planning: An integrated approach

    International Nuclear Information System (INIS)

    The International Atomic Energy Agency (IAEA) has published material on different policy considerations in the introduction of nuclear power, primarily addressed to top level decision makers in government and industry in Member States. Several Member States and experts recommended to the IAEA to address the aspects of an integrated approach to nuclear power programme planning and to serve as guidance to those countries wishing to embark on a nuclear power programme. As a follow-up, the present publication is primarily intended to serve as guidance for executives and managers in Member States in planning for possible introduction of nuclear power plants in their electricity generating systems. Nuclear power programme planning, as dealt with in this publication, includes all activities that need to be carried out up to a well-founded decision to proceed with a project feasibility study. Project implementation beyond this decision is not in the scope of this publication. Although it is possible to use nuclear energy as a heat source for industrial processes, desalination and other heat applications, it is assumed in this publication that the planning is aimed towards nuclear power for electricity generation. Much of the information given would, however, also be relevant for planning of nuclear reactors for heat production. The publication was prepared within the framework of the IAEA programme on nuclear power planning, implementation and performance as a joint activity of the Nuclear Power Engineering Section and the Planning and Economic Studies Section (Division of Nuclear Power)

  10. Nuclear power infrastructure and planning

    International Nuclear Information System (INIS)

    There are several stages in the process of introducing nuclear power in a country. These include feasibility studies; technology evaluation; request for proposals and proposal evaluation; project and contracts development and financing; supply, construction, and commissioning; and finally operation. The IAEA is developing guidance directed to provide criteria for assessing the minimum infrastructure necessary for: a) a host country to consider when engaging in the implementation of nuclear power, or b) a supplier country to consider when assessing that the recipient country would be in an acceptable condition to begin the implementation of nuclear power. There are Member States that may be denied the benefits of nuclear energy if the infrastructure requirements are too large or onerous for the national economy. However if co-operation could be achieved, the infrastructure burden could be shared and economic benefits gained by several countries acting jointly. The IAEA is developing guidance on the potential for sharing of nuclear power infrastructure among countries adopting or extending nuclear power programme

  11. Nuclear power and energy planning

    International Nuclear Information System (INIS)

    With the rapid depletion of conventional energy sources such as coal and oil and the growing world demand for energy the question of how to provide the extra energy needed in the future is addressed. Relevant facts and figures are presented. Coal and oil have disadvantages as their burning contributes to the greenhouse gases and they will become scarcer and more expensive. Renewable sources such as wind and wave power can supply some but not all future energy requirements. The case made for nuclear power is that it is the only source which offers the long term prospect of meeting the growing world energy demand whilst keeping energy costs close to present levels and which does not add to atmospheric pollution. Reassurance as to the safety of nuclear power plants and the safe disposal of radioactive wastes is given. (UK)

  15. Combination of AC Transmission Expansion Planning and Reactive Power Planning in the restructured power system

    International Nuclear Information System (INIS)

    Highlights: ► To overcome the disadvantages of DC model in Transmission Expansion Planning, AC model should be used. ► The Transmission Expansion Planning associated with Reactive Power Planning results in fewer new transmission lines. ► Electricity market concepts should be considered in Transmission Expansion Planning problem. ► Reliability aspects should be considered in Transmission Expansion Planning problem. ► Particle Swarm Optimization is a suitable optimization method to solve Transmission Expansion Planning problem. - Abstract: Transmission Expansion Planning (TEP) is an important issue in power system studies. It involves decisions on location and number of new transmission lines. Before deregulation of the power system, the goal of TEP problem was investment cost minimization. But in the restructured power system, nodal prices, congestion management, congestion surplus and so on, have been considered too. In this paper, an AC model of TEP problem (AC-TEP) associated with Reactive Power Planning (RPP) is presented. The goals of the proposed planning problem are to minimize investment cost and maximize social benefit at the same time. In the proposed planning problem, in order to improve the reliability of the system the Expected Energy Not Supplied (EENS) index of the system is limited by a constraint. For this purpose, Monte Carlo simulation method is used to determine the EENS. Particle Swarm Optimization (PSO) method is used to solve the proposed planning problem which is a nonlinear mixed integer optimization problem. Simulation results on Garver and RTS systems verify the effectiveness of the proposed planning problem for reduction of the total investment cost, EENS index and also increasing social welfare of the system.

  16. Workforce Planning for New Nuclear Power Programmes

    International Nuclear Information System (INIS)

    An appropriate infrastructure is essential for the efficient, safe, reliable and sustainable use of nuclear power. The IAEA continues to be encouraged by its Member States to provide assistance to those considering the introduction of nuclear power. Its response has been to increase technical assistance, organize more missions and hold workshops, as well as to issue new and updated publications in the IAEA Nuclear Energy Series. Milestones in the Development of a National Infrastructure for Nuclear Power, an IAEA Nuclear Energy Series publication (NG-G-3.1), provides detailed guidance on a holistic approach to national nuclear infrastructure development involving three phases. Nineteen issues are identified in this guide, ranging from development of a government's national position on nuclear power to planning for procurement related to the first nuclear power plant. One of these 19 issues upon which each of the other 18 depend is suitable human resources development. As a growing number of Member States begin to consider the nuclear power option, they ask for guidance from the IAEA on how to develop the human resources necessary to launch a nuclear power programme. The nuclear power field, comprising industry, government authorities, regulators, R and D organizations and educational institutions, relies on a specialized, highly trained and motivated workforce for its sustainability and continued success, quite possibly more than any other industrial field. This report has been prepared to provide information on the use of integrated workforce planning as a tool to effectively develop these resources for the spectrum of organizations that have a stake in such nuclear power programmes. These include, during the initial stages, a nuclear energy programme implementing organization (NEPIO), as well as the future operating organization, nuclear regulatory body, government authorities and technical support organizations if a decision is made to initiate a nuclear power

  17. Standard metrics and methods for conducting Avian/wind energy interaction studies

    Anderson, R.L. [California Energy Commission, Sacramento, CA (United States); Davis, H. [National Renewable Energy Lab., Golden, CO (United States); Kendall, W. [National Biological Service, Laurel, MD (United States)] [and others


    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.

    Oloomi Buygi, Majid


    The main goal of this thesis is to present a centralized static approach for transmission expansion planning in deregulated power systems. Restructuring and deregulation have unbundled the roles of network stakeholders. They exposed transmission planner to the new objectives and uncertainties. Unbundling the roles has brought new challenges for stakeholders. In these environments, stakeholders have different desires and expectations from the performance and expansion of the system. Therefore,...

  20. 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.


    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.

  1. Orbiter Auxiliary Power Unit Flight Support Plan (United States)

    Guirl, Robert; Munroe, James; Scott, Walter


    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.

  2. Nuclear power in Asia: Experience and plans

    International Nuclear Information System (INIS)

    Asian countries have developed ambitious energy supply programs to expand their energy supply systems to meet the growing needs of their rapidly expanding economies. Most of their new electrical generation needs will be met by coal, oil and gas. However, the consideration of growing energy demand, energy security, environmental conservation, and technology enhancement is inducing more Asian countries toward the pursuit of nuclear power development. At present, nuclear power provides about 30% of electricity in Japan, and about 40% of electricity in Korea. These and other Asian countries are presumed to significantly increase their nuclear power generation capacities in coming years. Korea's nuclear power generation facilities are projected to grow from 12 gigawatt in 1998 to 16.7 gigawatt by 2004. On the other hand, China and India have now installed nuclear capacities of about 2 gigawatt, respectively, which will increase by a factor of two or more by 2004. The installed nuclear capacity in the Asian region totalled 67 gigawatt as of the end of 1997, representing about sixteen percent of the world capacity of 369 gigawatt. Looking to the year 2010, it is anticipated that most of the world's increase in nuclear capacity will come from Asia. It is further forecasted that Asian nations will continue to expand their nuclear capacity as they move into the 21st century. For example, China plans to develop additional 18 gigawatt of nuclear power plants by the year 2010. Nuclear power is also of particular interest to a number of emerging Asian countries in view of environmental conservation and mitigation of greenhouse gas emissions in particular. Nuclear power appeals to some countries because of its high technology content. The strength in an advanced technology, such as the technological capability related to nuclear power, contributes to the overall development of the corresponding country's engineering base, enhancement of industrial infrastructure and expansion of

  3. Solar power deployment: Forecasting and planning (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.

  4. Reactive power planning incorporating voltage stability

    Energy Technology Data Exchange (ETDEWEB)

    Chattopadhyay, D. [University of Canterbury, Christchurch (New Zealand). Dept. of Management; Chakrabarti, B.B. [Transpower New Zealand Ltd., Wellington (New Zealand). Network Planning Group


    This paper addresses some of the modeling and economic issues pertaining to reactive power planning. We present a new VAR planning model, propose an efficient solution algorithm, and discuss the economic issues. A contingency constrained OPF-based model incorporating (static) voltage stability constraints is developed to analyze VAR support decisions. DICOPT++, a state-of-the-art non-linear mixed integer programming (MINLP) algorithm, is proposed to solve the model efficiently. The sensitivity information elicited from the optimization model may also provide useful aid to network planning that are discussed. The VAR support cost allocation issue is addressed next. The Shapley value criterion of cooperative gaming is proposed to allocate VAR support costs among the loads contributing to voltage instability. The VAR planning model is implemented for the AEP 14-bus test system. The implications of the sensitivity information are discussed using the test system results. The result of the optimization approach is compared with two existing methods viz., Eigen Value (Modal) and Singular Value Decomposition (SVD) methods. Further, we discuss how the outcome of the Modal analysis could be integrated in the optimization model to form a hybrid approach. A numerical example of calculation of Shapley value is provided and, we also compare it with the conventional method of proportional allocation to gain better insight about this criterion. (Author)

  5. Nuclear power plant Severe Accident Research Plan

    International Nuclear Information System (INIS)

    The Severe Accident Research Plan (SARP) will provide technical information necessary to support regulatory decisions in the severe accident area for existing or planned nuclear power plants, and covers research for the time period of January 1982 through January 1986. SARP will develop generic bases to determine how safe the plants are and where and how their level of safety ought to be improved. The analysis to address these issues will be performed using improved probabilistic risk assessment methodology, as benchmarked to more exact data and analysis. There are thirteen program elements in the plan and the work is phased in two parts, with the first phase being completed in early 1984, at which time an assessment will be made whether or not any major changes will be recommended to the Commission for operating plants to handle severe accidents. Additionally at this time, all of the thirteen program elements in Chapter 5 will be reviewed and assessed in terms of how much additional work is necessary and where major impacts in probabilistic risk assessment might be achieved. Confirmatory research will be carried out in phase II to provide additional assurance on the appropriateness of phase I decisions. Most of this work will be concluded by early 1986

  6. Options for Bulgaria power system extension planning

    International Nuclear Information System (INIS)

    Under the existing transition to market economy in Bulgaria, the planning of development of electricity generation is among the priorities of the national policy of restructuring and renovation of electricity system in the country. Optimal plans for development of the generation capacity are worked out by means of optimization procedure part of ENPEP package (ELECTRIC module) based on the dynamic programming technique. The optimal plans study three main strategies for development of energy capacities, which have to do with the priority of some type of natural resources--Coal, Natural Gas and Nuclear Energy. The Hydro Power Plant construction and loading schedule for each scenario is different and it harmonized with the maneuverability of other capacities. Coal scenario emphasizes the opportunities for the maximizing of local coal mining, substitution of black coal (energy and coke) import by mining of local coal fields and implementation of efficient and environmentally sound technologies when constructing new thermal power plants. Gas scenario envisages natural gas consumption within the limit of existing capacities of the national and transit pipelines. In this connection, the share of the new generating capacities using combined cycle increases their share. Nuclear scenario assumes increased share of the nuclear units at the expense of local coal mining and natural gas. This is due to the rehabilitation of 1,000 MW units in NPP Kozloduy, completion of a 1,000 MW unit in new NPP and construction of 1--2 new units 600 MW after 2010. The data obtained outlines the perspectives for development of energy generation capacities in Bulgaria for the period 2000--2020, tendencies in the generation structure and the share of each different type of generation units in the structure of electricity generation system. Output information serves as a sound base for conclusions on the advantages and disadvantages of the three strategies

  7. Supply disruption cost for power network planning

    International Nuclear Information System (INIS)

    A description is given of the method of approach to calculate the total annual socio-economic cost of power supply disruption and non-supplied energy, included the utilities' cost for planning. The total socio-economic supply disruption cost is the sum of the customers' disruption cost and the utilities' cost for failure and disruption. The mean weighted disruption cost for Norway for one hour disruption is NOK 19 per kWh. The customers' annual disruption cost is calculated with basis in the specific disruption cost referred to heavy load (January) and dimensioning maximum loads. The loads are reduced by factors taking into account the time variations of the failure frequency, duration, the loads and the disruption cost. 6 refs

  8. Improving acceptance in wind power planning

    Energy Technology Data Exchange (ETDEWEB)

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


    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 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 idealogical and practical contradictions between the development and preservation of landscapes. (author)

  12. Overhead power lines. Planning, design, construction

    Energy Technology Data Exchange (ETDEWEB)

    Kiessling, F.; Nefzger, P.; Nolasco, J.F.; Kaintzyk, U. [Siemens AG, Power Transmission and Distribution, Erlangen (Germany)


    The basic elements of overhead power line technology have been known for many years. However, this technology has continuously developed, for example, to adjust design of the lines to new transmission needs, to available rights-of-way, and to accommodate environmental concerns or resources. Since many existing overhead line installations are approaching the end of their economic and technical lifetime, strategies for maintenance to extending their operational life are needed. Also, because fo the introduction of new standards and deregulation, the basis of design and verification for all aspects and steps in overhead line planning and construction has changed. The industry, therefore, requires a publication reflecting these developments and changes. Overhead Power Lines presents not only the scientific and engineering basis for the electric and mechanical design, but also comprehensively describes all aspects of most recent technology, including the selection and design of components such as conductors, insulators, fittings, supports and foundations. The chapters on line survey, construction and maintenance address updated requirements and solutions. In addition, the book carefully considers the changing economic and technical environment of the overhead power line business. This publication is intended to introduce students and beginners to the full range of relevant topics of line design and implementation and to serve as a valuable reference to engineers and technicians employed by overhead line operators, contractors and consulting companies to carry out their daily tasks. The book also supplies everyone else in the electric-energy supply industry, including design, maintenance, and construction engineers, with a ready reference. This first English-language edition is based on the 5th German-language edition and incorporates the latest international standards edited by Cigre, the International Council of Large Electric Systems, IEC and CENELEC.

  14. Power plant construction. Plan, build, repair

    International Nuclear Information System (INIS)

    Modern thermal power plants can now convert up to 90 % of the energy input into electricity. This increase in efficiency has been made possible through technological progress, but also through improvements in power plant construction. Despite a distinct rise in the proportion of renewable energies in electricity supplies, traditional power stations are still responsible for guaranteeing a large share of our energy supplies. Air pollution control, noise control, protection of natural waters and soils plus careful use of resources are the key themes in the design, construction and maintenance of power plants. Publishing house Ernst and Sohn provides competent, up-to-date information for civil and structural engineers entrusted with such challenging engineering tasks. The special issue ''Power Plant Construction'' brings together the appropriate articles from the journals ''Bautechnik'', ''Stahlbau'', ''Beton- und Stahlbetonbau'' and ''Geomechanics and Tunnelling''. The themes in this compendium cover a wide range of topics, including analysis and design of power plant installations, power station refurbishment and maintenance, special structures such as cooling towers, chimneys and boiler house frames plus the engineering aspects of coal-fired, nuclear and hydroelectric power stations. Reports on current products and projects complement the technical papers. (orig.)

  15. Energy and nuclear power planning study for Armenia

    International Nuclear Information System (INIS)

    The Energy and Nuclear Power Planning (ENPP) study for Armenia has been conducted under the technical cooperation programme of the International Atomic Energy Agency (IAEA). The objective of the study was to analyze the electricity demand as part of the total final energy demand in various scenarios of Armenian socioeconomic and technological development, and to develop economically optimized electric generating system expansion plans for meeting the electric power demand, and to assess the role that nuclear energy could play within these optimal programs. The specific objectives of this study were: to define the role that nuclear power could play in the future electricity supply in Armenia, based on a least-cost expansion planning analysis of the country's power system; to analyze the environmental impacts of such a nuclear power development; to evaluate the financial viability of the envisaged nuclear power development program; to train a group of Armenian experts in the use of the IAEA's energy models

  18. Nuclear power planning study for Saudi Arabia

    International Nuclear Information System (INIS)

    The prospects of application of nuclear energy for production of electricity and desalinated water in the Kingdom are evaluated. General economic development of the country and data on reserves, production and consumption of oil and natural gas are reviewed. Electrical power system is described with data on production and consumption. Estimates of future power demand are made using Aoki method. Costs of production of electricity from 600 MW, 900 MW and 1200 MW nuclear and oil-fired power plants are calculated along with the costs of production of desalinated water from dual purpose nuclear and oil-fired plants. The economic analysis indicates that the cost of production of electricity and desalinated water are in general cheaper from the nuclear power plants. Suggests consideration of the use of nuclear energy for production of both electricity and desalinated water from 1415 H. Further detailed studies and prepartory organizational steps in this direction are outlined. 38 Ref

  19. Power requirements in an electrodialysis desalination plan

    International Nuclear Information System (INIS)

    Electrolysis is a desalination technique employing cation and anion selective membranes to remove the salt ions under the influence of electrical energy. Direct current (DC) based power is required to desalinate the feed stream of saline water. An alternate current (AC) is to be there to pump the feed water through the plant and to maintain proper flow through an electrodialysis plant. Both the types of power segments have been determined as a function of feed stream velocity (3 to 15 cm/s) The DC power required for a 0.2 mgd plant is in the order of 5Kwt. Hr per 1000 gallons of product water for a salt removal of 1000 PPM at a solution velocity of 9.24cm/s,. The Pumping power requirement for this has been estimated to be 3Kwt. hr per 1000 gallons of product water. (author)

  20. Nonlinear integrated resource strategic planning model and case study in China's power sector planning

    International Nuclear Information System (INIS)

    In this paper we expand the IRSP (integrated resource strategic planning) model by including the external cost of TPPs (traditional power plants) and popularization cost of EPPs (efficiency power plants) with nonlinear functions. Case studies for power planning in China during 2011–2021 are conducted to show the efficacy of the model. Scenarios are compiled to compare the pathways of power planning under different policies. Results show that: 1) wind power will become competitive with technical learning, but its installation is undesirable when the external cost of coal power is not internalized; 2) the existence of popularization cost will hinder EPPs' (efficiency power plants) deployment and pure market mechanism is not enough to deliver EPPs at socially desirable scale; 3) imposition of progressive emission tax on coal power at an average of 0.15–0.20 RMB/KWh can remedy the market distortion and promote the development of wind power by a significant margin; 4) nuclear power will grow stably when its external cost is set no more than 0.187 RMB per KWh, or 87% of its internal cost. The proposed model can serve as a useful tool for decision support in the process of power planning and policy formulation for national government. - Highlights: • Improve IRSP model by adding nonlinear external and popularization cost. • The model is used to conduct China's power sector planning in 2011–2021. • Simulate the impacts of alternative energy policies on planning results. • The model can be used for joint power sector planning and policy design

  4. Planning Mechanisms for Regional Electric Power Supply System Development

    Directory of Open Access Journals (Sweden)

    Evgeniy Anatolyevich Malyshev


    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. The possibility to apply the PPP mechanism for regional

  6. Short Term Hydro Power Planning Coordinated with Wind Power in Areas with Congestion Problems

    International Nuclear Information System (INIS)

    In this paper a day-ahead planning algorithm for a multi-reservoir hydropower system coordinated with wind power is developed. Coordination applies to real situations, where wind power and hydropower are owned by different utilities, sharing the same transmission lines, though hydropower has priority for transmission capacity. Coordination is thus necessary to minimize wind energy curtailments during congestion situations. The planning algorithm accounts for the uncertainty of wind power forecasts and power market price uncertainty. Planning for the spot market and the regulating market is considered in the algorithm. The planning algorithm is applied to a case study and the results are summarized in the paper. Index Terms wind power production, hydro power production, wind forecast uncertainty, power market, stochastic optimization.

  7. Planning for decommissioning power plants in Japan

    Komatsu, Junji (Research Association for Nuclear Facility Decommissioning, Tokaimura, Ibaraki (Japan))


    The first decommissioning of a commercial nuclear power plant in Japan is not expected before the early 2000s, but the technology and regulations needed are being developed now. Valuable technical experience is being gained from three current projects. These are the decommissioning of the Japan Reprocessing Test Facility, the Japan Power Demonstration Reactor and the nuclear ship Mutsu. Improving and commercialising the technology are seen as essential for the future to reduce occupational radiation exposure, the amount of waste and costs. International cooperation and information exchange are of increasing importance for developing technology and regulations. (U.K.).

  13. Power generation planning: a survey from monopoly to competition

    International Nuclear Information System (INIS)

    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.

  14. Fujian electric system analysis and nuclear power planning

    International Nuclear Information System (INIS)

    The objective of the study is to conduct a long term electric expansion planning and nuclear power planning for Fujian Province. The Wien Automatic System Planning Package (WASP-III) is used to optimize the electric system. Probabilistic Simulation is one of the most favorite techniques for middle and long term generation and production cost planning of electric power system. The load duration curve is obtained by recording the load data of a time interval into a monotone non-increasing sense. Polynomial function is used to describe the load duration curve (LDC), and this LDC is prepared for probabilistic simulation in WASP-III. WASP-III is a dynamic optimizing module in the area of supply modelling. It could find out the economically optimal expansion plan for a power generating system over a period of up to thirty years, with the constraints given by the planners. The optimum is evaluated in terms of minimum discounted total costs. Generating costs, amount of energy not served and reliability of the system are analyzed in the system expansion planning by using the probabilistic simulation method. The following conclusions can be drawn from this study. Hydro electricity is the cheapest one of all available technologies and resources. After the large hydro station is committed at the end of 1995, more base load power plants are needed in the system. Coal-fired power plants with capacity of 600 MWe will be the most competitive power plants in the future of the system. At the end of the studying period, about half of the stalled capacity will be composed of these power plants. Nuclear power plants with capacity of 600 MWe are suitable for the system after the base load increases to a certain level. Oil combustion units will decrease the costs of the system.

  15. Kilowatt isotope power system. Phase II plan. Volume I. Phase II program plan

    International Nuclear Information System (INIS)

    The development of a Kilowatt Isotope Power System (KIPS) was begun in 1975 for the purpose of satisfying the power requirements of satellites in the 1980's. The KIPS is a 238PuO2-fueled organic Rankine cycle turbine power system to provide a design output of 500 to 2000 W. Phase II of the overall 3-phase KIPS program is described. This volume presents a program plan for qualifying the organic Rankine power system for flight test in 1982. The program plan calls for the design and fabrication of the proposed flight power system; conducting a development and a qualification program including both environmental and endurance testing, using an electrical and a radioisotope heat source; planning for flight test and spacecraft integration; and continuing ground demonstration system testing to act as a flight system breadboard and to accumulate life data

  16. Reagan Energy plan: a major power failure

    International Nuclear Information System (INIS)

    The current Reagan energy policy is reviewed and discussed. The present administration's policy emphasizes increasing energy supplies through: (1) greater reliance on nuclear fission; (2) accelerating and subsidizing the production of fossil-based fuels; (3) truncating federal support for renewable energy resources and energy-efficiency measures; and (4) cutting back energy-assistance programs for middle and low income consumers. Nuclear power is discussed with emphasis on regulatory problems, reprocessing of nuclear fuel, the breeder reactor program and disposal of radioactive wastes. Arguments are presented for curtailing the nuclear energy program and providing greater support for solar energy, other renewable energy sources, and energy conservation programs. Financial incentive programs for the petroleum, gas, and nuclear energy industries are criticized; arguments are presented for greater financial incentives for solar installations, solar information sources, photovoltaics, etc. With proper funding, it is proposed that renewable energy sources could meet 20 to 30% of energy needs by the year 2000


    Energy Technology Data Exchange (ETDEWEB)



    BNL could provide a Megawatt class neutrino beam from the AGS for very long baseline neutrino experiments. We have studied two possible approaches to upgrade the AGS to 1.0 MW beam power. The first is the linac option, comprising a new superconducting linac injector of 1.2 GeV, accelerating 9 x 10{sup 3} proton per pulse in the AGS to 28 GeV at 2.5 Hz. The second option is to extend the existing 200 MeV linac to 400 MeV. ramp the Booster to 2.5 GeV at 6 Hz. add a new 2.5 GeV accumulator ring in the AGS tunnel. and finally ramp the AGS to 28 GeV at 2.5 Hz. Due to the simplicity of the linac approach and minimum interference with the on going research program. the linac option is the preferred one.

  18. Expansion planning for electric power systems

    International Nuclear Information System (INIS)

    Electricity is so basic to the world economy that certain electricity indices are used to express a country's economic standing (consumption or production of electricity per capita) and the standard of living enjoyed by a people (per capita electricity consumption in the domestic sector). Moreover, electricity supply has special characteristics which make the service unique as compared to other types of industry. The end product has to be delivered instantaneously and automatically upon the consumer's demand; except for pumped storage plants and electric batteries, technologies do not exist that can produce it economically at uniform rates, hold it in storage in large quantities, and deliver it under convenient schedules; insufficient capacity (shortage) or excessive capacity (idle capacity) have negative effects on the economy; the close inter-relation with economic and social factors imposes labour, environmental, financial and other constraints on the problem. Careful planning of the electric sector is therefore of great importance since the decisions to be taken involve the commitment of large resources, with potentially serious economic risks for the electrical utility and the economy as a whole

  5. Does health plan generosity enhance hospital market power? (United States)

    Baker, Laurence C; Bundorf, M Kate; Kessler, Daniel P


    We test whether the generosity of employer-sponsored health insurance facilitates the exercise of market power by hospitals. We construct indices of health plan generosity and the price and volume of hospital services using data from Truven MarketScan for 601 counties from 2001 to 2007. We use variation in the industry and union status of covered workers within a county over time to identify the causal effects of generosity. Although OLS estimates fail to reject the hypothesis that generosity facilitates the exercise of hospital market power, IV estimates show a statistically significant and economically important positive effect of plan generosity on hospital prices in uncompetitive markets, but not in competitive markets. Our results suggest that most of the aggregate effect of hospital market structure on prices found in previous work may be coming from areas with generous plans. PMID:26402570

  6. Green power: A renewable energy resources marketing plan

    International Nuclear Information System (INIS)

    Green power is electricity generated from renewable energy sources such as power generated from the sun, the wind, the heat of the earth, and biomass. Green pricing is the marketing strategy to sell green power to customers who voluntarily pay a premium for it. Green pricing is evolving from the deregulation of the electric industry, the need for clean air, reflected in part as concern over global warming, and technology advances. The goal of the renewable energy marketing plan is to generate enough revenues for a utility to fund power purchase agreements (PPAs) with renewable energy developers or construct its own renewable facilities. Long-term, fixed price PPAs enable developers to obtain financing to construct new facilities, sometimes taking technological risks which a utility might not take otherwise. The marketing plan is built around different rate premiums for different categories of ratepayers, volunteer customer participation, customer participation recognition, and budget allocations between project costs and power marketing costs. Green prices are higher than those for conventional sources, particularly prices from natural gas fired plants. Natural gas is abundant relative to oil in price per British thermal unit (Btu). Green pricing can help bridge the gap between the current oversupply of gas and the time, not far off, when all petroleum prices will exceed those for renewable energy. The rapid implementation of green pricing is important. New marketing programs will bolster the growing demand for renewable energy evidenced in many national surveys thus decreasing the consumption of power now generated by burning hydrocarbons. This paper sets forth a framework to implement a green power marketing plan for renewable energy developers and utilities working together

  7. Energy and nuclear power planning study for Algeria

    International Nuclear Information System (INIS)

    This study, conducted jointly by a team of engineers and economists from the Sonelgaz company and the IAEA, had three objectives: (1) To perform a preliminary economic study aimed at initiating thinking on the role that nuclear power could play in Algeria's long-term energy structure and to suggest reasonable hypotheses on what share of the energy market nuclear power might supply. (2) To train a team of Algerian engineers and economists in long-term economic planning techniques. Once the team has gained a basic knowledge through this preliminary study, it will be in a position to continue the process, to perform other, more detailed independent analyses and to review the entire process should economic conditions change. (3) To introduce in Algeria the computer techniques and facilities needed to carry out such energy investment planning studies for electricity production. The main aim throughout the studies was to train a team of Algerian engineers in energy planning rather than to come to definitive conclusions on the problem of introducing nuclear power in Algeria. Two successive analyses were performed. The first consisted in evaluating the final energy requirements which will result in the medium and long term (by 2015) from the implementation of the economic development policies in the Five Year Plan (up to 1984) and in the proposals for the next decade (up to 1990) being studied by the Algerian Ministry of Planning. The second part is concerned only with the results regarding future electricity requirements, which are used as input data in studying the optimization of Algeria's future electricity generating system. Various methods of generation are analysed and included in an econometric model in order to make a sequential determination of the most economic composition of power generating capacity

  8. Long-Term Planning in Restructured Power Systems

    International Nuclear Information System (INIS)

    This thesis describes the development of three decision support models for long-term investment planning in restructured power systems. The model concepts address the changing conditions for the electric power industry, with the introduction of more competitive markets, higher uncertainty and less centralised planning. Under these circumstances there is an emerging need for new planning models, also for analyses of the power system in a long-term perspective. The thesis focuses particularly on how dynamic and stochastic modelling can contribute to the improvement of decision making in a restructured power industry. We argue that the use of such modelling approaches has become more important after the introduction of competitive power markets, due to the participants' increased exposure to price fluctuations and economic risk. Our models can be applied by individual participants in the power system to evaluate investment projects for new power generation capacity. The models can also serve as a decision support tool on a regulatory level, providing analyses of the long-term performance of the power system under different regulations and market designs. In Chapter 1, we give a brief introduction to the ongoing development towards restructuring and liberalisation of the electrical power system. A discussion of the operation and organisation of restructured power systems is also provided. In Chapter 2, we look more specifically at different modelling approaches for expansion planning in electrical power systems. We also discuss how the contributions in this thesis compare to previous work in the field of decision support models for long-term planning in both regulated and competitive power systems. In Chapter 3, we develop a power market simulation model based on system dynamics. The advantages and limitations of using descriptive system dynamics models for long-term planning purposes in this context are also discussed. Chapter 4 is devoted to a novel optimisation

  9. Nuclear power plant thermal-hydraulic performance research program plan

    International Nuclear Information System (INIS)

    The purpose of this program plan is to present a more detailed description of the thermal-hydraulic research program than that provided in the NRC Five-Year Plan so that the research plan and objectives can be better understood and evaluated by the offices concerned. The plan is prepared by the Office of Nuclear Regulatory Research (RES) with input from the Office of Nuclear Reactor Regulation (NRR) and updated periodically. The plan covers the research sponsored by the Reactor and Plant Systems Branch and defines the major issues (related to thermal-hydraulic behavior in nuclear power plants) the NRC is seeking to resolve and provides plans for their resolution; relates the proposed research to these issues; defines the products needed to resolve these issues; provides a context that shows both the historical perspective and the relationship of individual projects to the overall objectives; and defines major interfaces with other disciplines (e.g., structural, risk, human factors, accident management, severe accident) needed for total resolution of some issues. This plan addresses the types of thermal-hydraulic transients that are normally considered in the regulatory process of licensing the current generation of light water reactors. This process is influenced by the regulatory requirements imposed by NRC and the consequent need for technical information that is supplied by RES through its contractors. Thus, most contractor programmatic work is administered by RES. Regulatory requirements involve the normal review of industry analyses of design basis accidents, as well as the understanding of abnormal occurrences in operating reactors. Since such transients often involve complex thermal-hydraulic interactions, a well-planned thermal-hydraulic research plan is needed

  14. Planning of emergency medical treatment in nuclear power plant

    International Nuclear Information System (INIS)

    Medical staffs and health physicists have shown deep concerning at the emergency plans of nuclear power plants after the TMI nuclear accident. The most important and basic countermeasure for accidents was preparing appropriate and concrete organization and plans for treatment. We have planed emergency medical treatment for radiation workers in a nuclear power plant institute. The emergency medical treatment at institute consisted of two stages, that is on-site emergency treatment at facility medical service. In first step of planning in each stage, we selected and treatment at facility medical service. In first step of planning in each stage, we selected and analyzed all possible accidents in the institute and discussed on practical treatments for some possible accidents. The manuals of concrete procedure of emergency treatment for some accidents were prepared following discussion and facilities and equipment for medical treatment and decontamination were provided. All workers in the institute had periodical training and drilling of on-site emergency treatment and mastered technique of first aid. Decontamination and operation rooms were provided in the facillity medical service. The main functions at the facility medical service have been carried out by industrial nurses. Industrial nurses have been in close co-operation with radiation safety officers and medical doctors in regional hospital. (author)

  15. Offshore wind power policy and planning in Sweden

    International Nuclear Information System (INIS)

    The main objective of this paper is to analyze the role of policy support schemes and planning systems for inducing offshore wind power development in Sweden. Specifically, it highlights the different types of economic, political and planning-related conditions that face offshore wind power investors in Sweden, and provides brief comparisons to the corresponding investment conditions in Denmark, Norway and the UK. The analysis shows that in Sweden existing policy incentives are generally too weak to promote a significant development of offshore wind power, and the paper provides a discussion about a number of political and economic aspects on the choice between different support schemes for offshore wind in the country. Swedish permitting and planning procedures, though, appear favorable to such a development, not the least in comparison to the corresponding processes in the other major offshore wind countries in Europe (e.g., the UK). On a general level the paper illustrates that the success and failure stories of national offshore wind policies and institutions cannot be easily transferred across country borders, and the analysis shows that both the political and the legal frameworks governing the investment situation for offshore wind farms in Denmark, Norway, Sweden and the UK differ significantly.

  16. Planning and development of the Spanish nuclear power programme

    International Nuclear Information System (INIS)

    The paper analyses the Spanish nuclear power programme from its inception to the present time, doing so within the context of the country, characterized by the fairly rapid change from a basically agricultural economy to an economy in which industry and services play an important part and the transformation of which took place mainly during the decade prior to the energy crisis 1973. Reference is made to the early establishment of the Junta de Energia Nuclear (Nuclear Energy Board) (JEN), which was set up as a research body even before nuclear energy became competitive with other sources for the production of electric power and which, by adapting its structure and programmes to the different phases in the development and utilization of nuclear energy in the country, contributed the necessary scientific, technical and legal infrastructure. There is also an analysis of the most striking features of the Spanish energy system and an account of the planning and construction of the first three Spanish nuclear power stations. A further subject of discussion is the energy planning and development projects devised by the Government which gave rise to the second generation of nuclear power plants, some of which are already in operation and the remainder in an advanced state of construction. Emphasis is placed on the action taken by the Spanish Government to increase the participation of Spanish industry in the construction of nuclear power plants and in the supply of equipment and services required for their operation. Reference is made to the experimental changes which have been made in the institutional infrastructure in order to adapt it to the phase of development which has been reached and to the objectives subsequently laid down in the planning: establishment of ENUSA (the national uranium enterprise), the Equipos Nucleares corporation and the Nuclear Safety Council, and also the changes made in the JEN

  17. Severe accident countermeasure plan (draft) for nuclear power plants

    International Nuclear Information System (INIS)

    Nuclear power plants should be designed, constructed, and operated properly so that the likelihood of occurrence of a severe accident and its consequence may be minimized. The Korea Institute of Nuclear Safety has been reviewing the Nuclear Safety Policy Statement and the preceding severe accident countermeasure plan and prepared a new draft plan in order to provide a reasonable regulatory position for severe accidents. This plan has been prepared by taking into account the different reactor types and the characteristics of operating plants, new plants using the existing design, and new ones including the next generation plants. The major elements included in the plan are: establishment and application of the safety goal, performance of the probabilistic safety assessment and establishment of countermeasure plans for the vulnerabilities, provisions for severe accidents prevention and mitigation capability, set-up of a severe accident management program implementation system. Each element has been set up to move progressively toward an upgrading in safety of currently operating plants and future ones

  18. Guidance for emergency planning in nuclear power plants

    International Nuclear Information System (INIS)

    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

Also, site and building well design focusing on escape pathways, emergency exits, and evacuation zones, and the safety procedures such as; evacuation exercises and sheltering processes according to different emergency classifications. In addition, this paper mentions some important codes and regulations that control nuclear power plants design, and assessment methods that evaluate probable risks. (author)

  20. Pulsed Power: Sandia's Plans for the New Millenium

    International Nuclear Information System (INIS)

    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

  1. Air quality analysis for the Western Area Power Administration's 2004 Power Marketing Plan Environmental Impact Statement

    International Nuclear Information System (INIS)

    The Western Area Power Administration (Western) markets and transmits electric power throughout 15 western states. Western's Sierra Nevada Customer Service Region (Sierra Nevada Region) markets approximately 1,480 megawatts (MW) of firm power (plus 100 MW of seasonal peaking capacity) from the Central Valley Project (CVP) and other resources. Western's mission is to sell and deliver electricity generated from these resources. Western's capacity and energy sales must be in conformance with the laws that govern its sale of electrical power. Further, Western's hydropower operations at each facility must comply with minimum and maximum flows and other constraints set by other regulatory agencies. The Sierra Nevada Region proposes to develop a marketing plan that defines the products and services it would offer beyond the year 2004 and the eligibility and allocation criteria for its electric power resources. Because determining levels of long-term firm power resources to be marketed and subsequently entering into contracts for the delivery of related products and services could be a major Federal action with potentially significant impacts to the human environment, the 2004 Power Marketing Plan Environmental Impact Statement (2004 EIS) is being prepared. Decisions made by the Sierra Nevada Region on how and when to supply power to its customers would influence the operation of power plants within the Western Systems Coordinating Council (WSCC). If the resources affected are thermal resources, this could in turn affect the amount, timing, and location of pollutant emissions to the air at locations throughout the western United States. This report has been produced in conjunction with the 2004 EIS to provide a more detailed discussion of the air quality implications of the 2004 power marketing plan

  2. Indicators for management of planned outages in nuclear power plants

    International Nuclear Information System (INIS)

    The outages considered within the scope of this publication are planned refuelling outages (PWR and BWR nuclear power plants) and planned outages associated with major maintenance, tests and inspections (PHWR and LWGR nuclear power plants). The IAEA has published some valuable reports providing guidance and assistance to operating organizations on outage management. This TECDOC outlines main issues to be considered in outage performance monitoring and provides guidance to operating organizations for the development and implementation of outage programmes which could enhance plant safety, reliability and economics. It also complements the series of reports published by the IAEA on outage management and on previous work related to performance indicators developed for monitoring different areas of plant operation, such as safety, production, reliability and economics. This publication is based upon the information presented at a technical meeting to develop a standardized set of outage indicators for outage optimization, which was organised in Vienna, 6-9 October 2003. At this meeting, case studies and good practices relating to performance indicator utilization in the process of planned outage management were presented and discussed

Under certain conditions using a planned missing design will increase power, whereas in other situations using a planned missing design…

  4. Planning of the Paks Nuclear Power Plant Pt. 1

    International Nuclear Information System (INIS)

    The major stages of the planning of the first Hungarian nuclear power plant following the Soviet - Hungarian agreement in 1966 concerning the complete transfer of 4 blocks of WWER-type reactor by the Soviet partner are reviewed. The original standard project was modified in 1973 due to some basic variations on the reactor type to reduce environmental contamination risks. In addition to the evident planning difficulties arising from the modification of the reactor type and the changing of the national circumstances, standards, methods of design, etc., co-operational problems in the design due to misunderstandings between the partners, frequent modifications of the delivered components relative to the scecified ones, insufficiencies in the specifications can be responsible for the postponement of the deadline of commissioning.

It is also presented the calculation of the probability distribution of the system interruption cost to improve the decision making process associated with alternative operational strategies. The Brazilian Southeastern system is used to illustrate all previous applications. (author) 24 refs., 8 figs., 4 tabs.

  7. New developments in planning of reactive power compensation devices

    International Nuclear Information System (INIS)

    The need to compensate reactive-power is highlighted by the well-known problem that arises when starting up very powerful nuclear plants, sometimes located very far away from the areas of consumption. Since the EHV network is very expanded and highly meshed, such need varies considerably as a function of the availability of the generating units and the grid. To tackle this problem, the authors have drawn up a new, basically probabilistic, method which accounts for the great many different situations characterizing a large meshed network (1000 nodes) while providing reasonably safe operating conditions in case of n-1 contingency. It is today an operational method. The authors illustrate it with the results of a recent study on compensation device-planning on the EHV EDF network by 1990

  8. Case study : power distribution PBR plans of National Grid USA

    International Nuclear Information System (INIS)

    This power point presentation described the progressive approach taken by the Northeastern United States towards electric power restructuring and performance based ratemaking (PBR) with reference to National Grid USA and the NEES tradition of pursuing regulatory matters. The catalyst for change was the NEES acquisition of EUA (and National Grid USA acquisition of NEES). Another catalyst for change was the desire to merge operating companies and consolidate rates. This paper described the settlement negotiations of the New England Process with reference to meeting the customer's desire for lower electricity prices and rate stability.The paper also described a multi-year PBR-based plan proposed for Niagara Mohawk which offers incentives for both cost efficiency and service quality. It was concluded that PBR is a sound basis for optimizing customer and shareholder benefits. It was emphasized that while PBR has universal application, detailed implementation must be sensitive to local issues and priorities. tabs., figs

  9. Electricity generation and transmission planning in deregulated power markets (United States)

    He, Yang

    This dissertation addresses the long-term planning of power generation and transmission facilities in a deregulated power market. Three models with increasing complexities are developed, primarily for investment decisions in generation and transmission capacity. The models are presented in a two-stage decision context where generation and transmission capacity expansion decisions are made in the first stage, while power generation and transmission service fees are decided in the second stage. Uncertainties that exist in the second stage affect the capacity expansion decisions in the first stage. The first model assumes that the electric power market is not constrained by transmission capacity limit. The second model, which includes transmission constraints, considers the interactions between generation firms and the transmission network operator. The third model assumes that the generation and transmission sectors make capacity investment decisions separately. These models result in Nash-Cournot equilibrium among the unregulated generation firms, while the regulated transmission network operator supports the competition among generation firms. Several issues in the deregulated electric power market can be studied with these models such as market powers of generation firms and transmission network operator, uncertainties of the future market, and interactions between the generation and transmission sectors. Results deduced from the developed models include (a) regulated transmission network operator will not reserve transmission capacity to gain extra profits; instead, it will make capacity expansion decisions to support the competition in the generation sector; (b) generation firms will provide more power supplies when there is more demand; (c) in the presence of future uncertainties, the generation firms will add more generation capacity if the demand in the future power market is expected to be higher; and (d) the transmission capacity invested by the

  11. Planning the nuclear contribution to the Brazilian power programme

    International Nuclear Information System (INIS)

    Thermo-electric power in Brazil accounts for less than 20% of the total generating capacity. Brazil's power is essentially generated hydraulically, which ensures the growing development. The electric energy consumption keeps growing, with an annual average rate of 13% over the last five years. The present installed capacity is 20,000MW(e) and 185,000MW(e) are forecast for the year 2000. Most of the hydraulic resources are located in remote areas of the country very far from the consumption centres. In addition to the American-made nuclear power station under construction in Angra dos Reis with a power capacity of 626MW(e), the agreement signed in June 1975 between the Federal Republic of Germany and Brazil covers two more units, each of 1245MW(e) capacity, to be erected at the same site and planned to come into operation in 1982 and 1983. Several joint German-Brazilian companies will be established in the country for reactor and fuel manufacture. The Brazilian state holding nuclear company, Empresas Nucleares Brasileiras S A (Nuclebras), will participate in the formation of all joint companies with at least 51% of the capital investment. During the period of the agreement the Brazilian Government will encourage the development of technology and reduce the dependence on energy imports. Brazil's target is full independence in nuclear technology in about 15 years. (author)

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

    Directory of Open Access Journals (Sweden)

    Aida Fazliana Abdul Kadir


    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.

  15. Shippingport Atomic Power Station Operating Experience, Developments and Future Plans

    International Nuclear Information System (INIS)

    This paper describes and evaluates five years of operation and test of the Shippingport Atomic Power Station and discusses the current technical developments and future plans of the Shippingport programme. This programme is directed towards development of the basic technology of light-water reactors to provide the basis for potential reduction in the costs of nuclear power. The Shippingport reactor plant has operated for over five years and has been found to integrate readily into a utility system either as a base load or peak load unit. Plant component performance has been reliable. There have been no problems in contamination or waste disposal. Access to primary coolant components for maintenance has been good, demonstrating the integrity of fuel elements. Each of the three refuelling operations performed since start-up of Shippingport has required successively less time to accomplish. Recently, the third seed was refuelled in 32 working days, about one quarter the time required for the first refuelling. The formal requirements of personnel training, written administrative procedures, power plant manuals, etc., which have been a vital factor in the successful implementation of the Shippingport programme, are described. The results obtained from the comprehensive test programme carried out at Shippingport are compared with calculations, and good agreement has been obtained. Reactor core performance, plant stability, and response to load changes, fuel element and control rod performance, long-term effects such as corrosion and radiation level build-up, component performance, etc., are discussed in this paper. The principal objective of the current and future programmes of the Shippingport Project in advancing the basic technology of water-cooled reactors is discussed. This programme includes the continued operation of the Shippingport plant, and the development, design, manufacture and test operation of a long-life, highpower density second core - Core 2. At its

    Zakrajsek, June F.; Woerner, Dave F.; Cairns-Gallimore, Dirk; Johnson, Stephen G.; Qualls, Louis


    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.

  17. Power plans seek funds [in Indo-China

    International Nuclear Information System (INIS)

    A conference in Vietnam on the Power Sector in Indochina and Myanmar in September 1995 is reported. The current power scenario in Vietnam and future government hopes and plans were outlined. In 1994 Vietnam had a total installed capacity of 4470 MW, of which 63% was hydropower. By 2010 it is hoped to increase total capacity to 18,000 MW with the hydropower contribution reduced to 50%. It is hoped to attract the US$20bn required to finance this development from investment by international organizations and private operators. However, problems exist in the form of uncertainties in Vietnamese law with respect to foreign investment and Vietnam's non-convertible currency. Vietnam is keen to attract hard currency but reluctant to let it out of the country as foreign companies would wish to do with their profits. Myanmar has been further to go than Vietnam in developing its huge hydropower resources to meet growing demand for electric power. About 40% of the country's peak demand of 550 MW is generated by hydropower but this represents only 1% of the total hydropower resource. Demand is expected to rise to 1500 MW by 2000. Again foreign investment is being sought. As in Vietnam, though, the question of an inconvertible currency arises. In addition, the subsidised low tariff in Myanmar promises only a low rate of return and the country is fighting high inflation. (U.K.)

    Energy Technology Data Exchange (ETDEWEB)

    Miketa, Asami [IRENA, Bonn (Germany); Merven, Bruno [Energy Research Centre, Univ. of Cape Town (South Africa)


    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).

  20. Institutional plan -- Institute of Nuclear Power Operations, 1993

    Energy Technology Data Exchange (ETDEWEB)


    The US nuclear electric utility industry established the Institute of Nuclear Power Operations (INPO) in 1979 to promote the highest levels of safety and reliability -- to promote excellence -- in the operation of its nuclear plants. After its formation, the Institute grew from a handful of on-loan personnel in late 1979 to an established work force of more than 400 permanent and on-loan personnel. INPO`s early years were marked by growth and evolution of its programs and organization. The Institute now focuses primarily on the effectiveness and enhancement of established programs and activities. For INPO to carry out its role, it must have the support of its members and participants and a cooperative but independent relationship with the NRC. A basis for that support and cooperation is an understanding of INPO`s role. This Institutional Plan is intended to provide that understanding by defining the Institute`s role and its major programs. This plan considers the existing and projected needs of the industry and the overall environment in which INPO and its members and participants operate.

    Energy Technology Data Exchange (ETDEWEB)

    Milligan, M.; Donohoo, P.; O' Malley, M.


    Wind and solar generators differ in their generation characteristics than conventional generators. The variable output and imperfect predictability of these generators face a stochastic approach to plan and operate the power system without fundamentally changing the operation and planning problems. This paper overviews stochastic modeling challenges in operations, generation planning, and transmission planning, with references to current industry and academic work. Different stochastic problem formulations, including approximations, are also discussed.

    Energy Technology Data Exchange (ETDEWEB)

    Trengereid, Frode


    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

  10. Modern power station practice, incorporating modern power system practice. Volume A: station planning and design; 3rd. ed.

    Energy Technology Data Exchange (ETDEWEB)

    Martin, P.C.; Hannah, I.W. [eds.


    The planning and design of new power stations can involve complex interaction between the many engineering disciplines involved as well as environmental, planning, economical, political and social pressures. This volume aims to provide a logical review of the procedures involved in power station development. The engineering aspects are outlined in detail, with examples, showing the basis of the relationships involved together with `non-engineering` factors so that the engineer can draw on the information provided for specific projects. The civil engineering and building of power stations are also treated, from the earliest planning and site selection studies, through estimating, finance and quantity surveying, to final landscaping. Main chapter headings are: power station siting and site layout; station design and layout; and civil engineering and building works. The book draws on experience gained by the CEGB through the commissioning of its large modern power stations in the United Kingdom. 216 figs.

  12. Implications of sustainability assessment for electricity system design: The case of the Ontario Power Authority's integrated power system plan

    International Nuclear Information System (INIS)

    This paper explores the results and implications of an illustrative application of a sustainability assessment framework in the design and evaluation of a major integrated power system plan. The paper examines the integrated power system plan developed by the Ontario Power Authority in 2007. The basic framework rests on a generic set of evaluation criteria reflecting basic requirements for progress towards sustainability that was adopted, reinterpreted and applied by the Authority in support of its proposed plan. In response to evident deficiencies in the Authority's work, the authors and colleagues undertook a re-examination using a more fully elaborated sustainability assessment framework, specified for application to power system planning. The results point to a plan and plan components substantially different from those proposed by the Authority. More generally, the results highlight three advantages of applying such a sustainability assessment framework: comprehensive coverage of key requirements for progress towards sustainability while ensuring careful attention to the context and concerns of the sector; emphasis on identifying plan options that avoid major trade-offs among the sustainability criteria and recognition of interactions among the social, ecological, economic and technological realms favouring options that offer multiple, mutually reinforcing and lasting benefits.

    The utilization coefficient as one of the characteristics of availability of nuclear power plants and the operation results (like maximum power, block number, and electric energy generation) are investigated by different statistic methods for several nuclear power plants with PWR type reactors and compared with those of WWER 440-type reactors. By means of linear many-parameter regression analysis the utilization coefficient is studied in dependence on block power and time after reactor commissioning. Forecastings of mean utilization coefficients are presented for the power of WWER 1000-type reactors

  16. Planning and licensing two replacement nuclear power plants in Switzerland

    International Nuclear Information System (INIS)

    Switzerland is facing the challenges of steadily rising electricity consumption and an aging pool of power plants. Its electricity mix of roughly 60% hydroelectric power and 40% nuclear power is the reason for its excellent carbon balance in electricity production. Consequently, replacement must be found for the oldest nuclear power plants and for future electricity import contracts. Security of supply, environmental protection, and economic performance must be taken into account in equal proportions. For the overarching strategic project of a ''replacement nuclear power plant'', 2 of the big Swiss electricity utilities, Axpo and BKW, in 2008 jointly founded a project development company, Resun AG. Performing the project design work in a joint effort allows synergies to be exploited and expenses to be focused. The 2003 Nuclear Power Act (KEG) of Switzerland provides a 3-stage plant licensing procedure. In addition, the political system in Switzerland offers a number of possibilities for involvement and participation at various stages in the licensing procedure of new nuclear power plants. The political debate about the future energy policy of Switzerland was triggered for good when the framework applications for approval of the replacement nuclear power plants were submitted. Construction of the replacement nuclear power plants corresponds to the political strategy, communicated by the Federal Council, to ensure future energy supply also by building new large power plants.

  17. Integrating Renewable and Nonrenewable Energies in Power Plant Planning

    Directory of Open Access Journals (Sweden)

    Habib H. Al-Ali


    Full Text Available Problem statement: Electricity can be generated from different type of technologies such as fossil and non-fossil power plants. Among these technologies, coal-fired power plants have been a major route for electricity generation. Recently, environmental constraints were imposed over the coal power plant operations in order to reduce their emissions. Besides, renewable energy power plants such as hydroelectric, wind, solar and geothermal have emerged with a potential of low impact on the environment. Approach: In this study, coal-fired power plants with a mix of low emission power plants were analyzed from the viewpoint of coal power plant emission reductions while supplying electricity demand. Electricity capacity expansion was also included within the problem to insure sufficient electricity supply in circumstances of emission reduction constraints. Results: Pollutants such as Nitrogen Oxides (NOx, Sulfur Oxides (SOx and mercury (Hg were assumed to be the target compounds. A discrete mathematical programming model was formulated to give an assessment about the coal-fired power plant operations in an electricity generation network. Different scenarios of increased electricity demand and emission reduction targets were applied on Ontario Power Generation (OPG network to give an illustration of the proposed model. Conclusion: The case study results show the significant impact of combining renewable energy or zero emission technologies on the optimal operation of a network that combines coal-fired power plants.

  18. Large-scale utilization of wind power in China: Obstacles of conflict between market and planning

    International Nuclear Information System (INIS)

    The traditional strict planning system that regulates China's power market dominates power industry operations. However, a series of market-oriented reforms since 1997 call for more decentralized decision-making by individual market participants. Moreover, with the rapid growth of wind power in China, the strict planning system has become one of the significant factors that has curtailed the generation of wind power, which contradicts with the original purpose of using the government's strong control abilities to promote wind power development. In this paper, we first present the reasons why market mechanisms are important for large-scale utilization of wind power by using a case analysis of the Northeast Grid, and then we illustrate the impact of conflicts between strict planning and market mechanisms on large-scale wind power utilization. Last, we explore how to promote coordination between markets and planning to realize large-scale wind power utilization in China. We argue that important measures include implementing flexible power pricing mechanisms instead of the current fixed pricing approach, formulating a more reasonable mechanism for distributing benefits and costs, and designing an appropriate market structure for large-scale wind power utilization to promote market liquidity and to send clear market equilibrium signals. - Highlights: ► We present the reasons why market is important for utilization of wind power. ► We discuss the current situation of the conflict between planning and market. ► We study the impact of conflict between planning and market on wind power output. ► We argue how to promote coordination between market and planning.

  19. Study on Battery Capacity for Grid-connection Power Planning with Forecasts in Clustered Photovoltaic Systems (United States)

    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%.

  2. Power Tower Technology Roadmap and cost reduction plan.

    Energy Technology Data Exchange (ETDEWEB)

    Mancini, Thomas R.; Gary, Jesse A. (U.S. Department of Energy); Kolb, Gregory J.; Ho, Clifford Kuofei


    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.

  3. Wind power planning: assessing long-term costs and benefits

    International Nuclear Information System (INIS)

    In the following paper, a new and straightforward technique for estimating the social benefit of large-scale wind power production is presented. The social benefit is based upon wind power's energy and capacity services and the avoidance of environmental damages. The approach uses probabilistic load duration curves to account for the stochastic interaction between wind power availability, electricity demand, and conventional generator dispatch. The model is applied to potential offshore wind power development to the south of Long Island, NY. If natural gas combined cycle and integrated gasifier combined cycle (IGCC) are the alternative generation sources, wind power exhibits a negative social benefit due to its high capacity cost and the relatively low emissions of these advanced fossil-fuel technologies. Environmental benefits increase significantly if charges for CO2 emissions are included. Results also reveal a diminishing social benefit as wind power penetration increases. The dependence of wind power benefits on CO2 charges, and capital costs for wind turbines and IGCC plant is also discussed. The methodology is intended for use by energy planners in assessing the social benefit of future investments in wind power

  4. Is EIA part of the wind power planning problem?

    International Nuclear Information System (INIS)

    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

  8. Integrated resource strategic planning: Case study of energy efficiency in the Chinese power sector

    International Nuclear Information System (INIS)

    In the last quarter of the 20th century, many power companies used the integrated resource planning (IRP) approach in power expansion planning. Today, very few power companies use this approach because of the split between the power generation and distribution activities. It seems that, in some countries, long-term power system expansion planning has become a task of the central government. To help the government in this area, this paper proposes a new approach called the integrated resource strategic planning (IRSP). When combined with a smart grid, this approach can replace the IRP for the government's power sector expansion. This paper introduces the necessity and possibility of using this new approach, presents a framework on how to use the approach, and justifies the effectiveness of this approach against the traditional power planning approach, with a case study in China. This paper concludes that if China follows the IRSP approach, it may be able to avoid or postpone up to 69 GW of power generation in the period 2009-2015. These measures could help mitigate 201.8 million tons of carbon dioxide (CO2), 0.816 million tons of sulfur dioxide (SO2), and 0.946 million tons of nitrogen oxide (NOx).

  17. Empirical study on voting power in participatory forest planning. (United States)

    Vainikainen, N; Kangas, A; Kangas, J


    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. PMID:17395363

  3. Planning for rate base treatment of large power plants

    International Nuclear Information System (INIS)

    This paper addresses two related areas of planning for inclusion in rate base of large generating stations. First, the paper discusses the range of options available as to how the plant is to go into rate base, e.g., phase-in plans. In this connection the process of generating the entire range of options that may be available is described and examined. Second, the paper examines innovative ways of using procedures (e.g., accounting proceedings, settlement procedures, cost caps, and other ideas short of a full-blown rate case) and the resources available in the ratemaking arena, to obtain, in the least painful way possible, the necessary ratemaking orders. The thesis is that there must be better alternatives to the many proceedings that have either begun as, or seem to be leading to, endless retrospective examinations of multiple questions (from load forecasting to construction management to continuation-of-construction decisions) under the label of prudence inquiries

Accuracy of dynamic response obtained from computer simulation depends on the accuracy of data, especially the hull resistance and propeller characteristics. Thi...

  5. Planning for decommissioning of Ignalina Nuclear Power Plant Unit-1

    International Nuclear Information System (INIS)

    In accordance to Ignalina NPP Unit 1 Closure Law, the Government of Lithuania approved the Ignalina NPP Unit 1 Decommissioning Program until 2005. For enforcement of this program, the plan of measures for implementation of the program was prepared and approved by the Minister of Economy. The plan consists of two parts, namely technical- environmental and social-economic. Technical-environmental measures are mostly oriented to the safe management of spent nuclear fuel and operational radioactive waste stored at the plant and preparation of licensing documents for Unit 1 decommissioning. Social-economic measures are oriented to mitigate the negative social and economic impact on Lithuania, inhabitants of the region, and, particularly, on the staff of Ignalina NPP by means of creating favorable conditions for a balanced social and economic development of the region. In this paper analysis of planned radioactive waste management technologies, licensing documents for decommissioning, other technical-environmental and also social-economic measures is presented. Specific conditions in Lithuania important for defining the decommissioning strategy are highlighted. (author)

  6. Power plant construction lead times: The value of contingency planning

    International Nuclear Information System (INIS)

    In this paper an analysis of two different approaches to the construction of a major power plant (nuclear) is presented. The analysis compares an accelerated, ''go-for-broke'' strategy-which has some risk of being delayed-with a more deliberate contingency construction schedule in terms of revenue requirements and costs of electricity. It is demonstrated that under a wide variety of circumstances there are important advantages to the contingency strategy, but that the magnitude of those advantages is sensitive to the character of the power system being examined and to the flexibility of the contingency approach

  13. Piloted Mars mission planning: NEP technology and power levels

    International Nuclear Information System (INIS)

    This paper examines the strong interrelationship between assumed technology and mission performance requirements for NEP. Recent systems analysis efforts by NASA, DOE, and various contractors are used to project achievable system performance as a function of technological sophistication for two piloted Mars mission applications. Specific mass regimes for each collection of technologies are presented as a function of power level for piloted applications. Low thrust mission analyses are presented which relate these system performance projections to achievable mission performance. Mission performance ''maps'' are constructed which link prime mission figures-of-merit of time and initial mass with system requirements on power level and specific mass, and hence technology. Both opposition and conjunction class piloted Mars missions are presented for the 2016 opportunity, analogous to those proposed in the ''90-Day Study'' and ''Synthesis'' architecture studies. Mass and time breakdowns are presented for 10 MWe piloted and 5 MWe cargo point designs

  19. Modeling and forecasting of electrical power demands for capacity planning

    International Nuclear Information System (INIS)

    Jordan imports oil from neighboring countries for use in power production. As such, the cost of electricity production is high compared to oil producing countries. It is anticipated that Jordan will face major challenges in trying to meet the growing energy and electricity demands while also developing the energy sector in a way that reduces any adverse impacts on the economy, the environment and social life. This paper described the development of forecasting models to predict future generation and sales loads of electrical power in Jordan. Two models that could be used for the prediction of electrical energy demand in Amman, Jordan were developed and validated. An analysis of the data was also presented. The first model was based on the levels of energy generated by the National Electric Power Company (NEPCO) and the other was based on the levels of energy sold by the company in the same area. The models were compared and the percent error was presented. Energy demand was also forecasted across the next 60 months for both models. Results were then compared with the output of the in-house forecast model used by NEPCO to predict the levels of generated energy needed across the 60 months time period. It was concluded that the NEPCO model predicted energy demand higher than the validated generated data model by an average of 5.25 per cent. 8 refs., 5 tabs., 15 figs

  20. Generation expansion planning in a competitive electric power industry (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.

  4. Novel binary PSO algorithm based optimization of transmission expansion planning considering power losses (United States)

    Astuty; Haryono, T.


    Transmission expansion planning (TEP) is one of the issue that have to be faced caused by addition of large scale power generation into the existing power system. Optimization need to be conducted to get optimal solution technically and economically. Several mathematic methods have been applied to provide optimal allocation of new transmission line such us genetic algorithm, particle swarm optimization and tabu search. This paper proposed novel binary particle swarm optimization (NBPSO) to determine which transmission line should be added to the existing power system. There are two scenerios in this simulation. First, considering transmission power losses and the second is regardless transmission power losses. NBPSO method successfully obtain optimal solution in short computation time. Compare to the first scenario, the number of new line in second scenario which regardless power losses is less but produces high power losses that cause the cost becoming extremely expensive.

  6. The long term plan for the integration of nuclear power plants into the Turkish Electrical Power System

    International Nuclear Information System (INIS)

    The report covers in detail the study of the expansion of the Turkish Electric Power System for the period 1980-1987. Load forecast is done by sectors and regions and inter-regions power balances gave the basis for the high voltage network configurations. Expansion alternatives are defined giving priority to hydroelectric projects, to local resources and nuclear power plants concurrently with conventional plants (lignite and oil). Several reactor strategies are analysed with LWR, HWR, FBR and HTGR power plants. Present worth value method is used for comparison of alternatives and sensitivity analysis is done for those ranked in the first places. Load flow, transient stability and frequency deviation studies of the power system are studied carefully by means of A.C. calculator and digital computer codes in order to see the influence of the introduction of large-sized power plants (600-750MW(e)) and their location in the power system. A 600MW(e) nuclear plant in 1983 and a second one of 750MW(e) in 1987 should, it is found, be commissioned into the system. The economic optimization was done with two computer programmes developed by KFA (Juelich): IACO for fuelling nuclear plant and RESTRAPO for power system with high hydroelectric component. The report is bound in three volumes: Volume I: Summary and Conclusions; Volume II: System Planning; Volume III: Electrical Survey

    International Nuclear Information System (INIS)

    The roles of state and local agencies in planning for and managing social and economic impacts of nuclear power plants are studied. In order to be effective in these roles state and local agencies must work with each other as well as the NRC. A comparative case study approach is used which analyzes six sites in three West Coast states. The case studies included plants in operation, plants under construction, and plants still in the planning stages. In contrast to some states, all three of these states have moderately centralized procedures for siting power plants, and all have strong environmental laws

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

    Directory of Open Access Journals (Sweden)

    Yuan Hu


    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.

  11. The socio-economic costs of the planned development of wind power energy

    International Nuclear Information System (INIS)

    The socio-economic consequences of the Danish government's planned further development of wind power energy are discussed in detail. It is claimed that, currently, electricity produced by wind turbines is more expensive than that produced by power stations, if the relative environmental effects are not taken into consideration. It is expected that technological development will contribute to cost reduction by the year 2010 so that electricity produced by wind turbines will be competitive, but until then costs of wind power energy will be high and it is reckoned that losses will be in the range of 5-6 billion Danish crowns, minus 2.5 billion saved by lack of CO2 emission. The socio-economic factors regarding windmills of various sizes (150 kW and 225 kW) are calculated and the planned development of wind power until 2010 is explained. The socio-economic costs of the development programme under various conditions, including the calculation of the saved emissions of carbon dioxide, are discussed. The author states that, in the light of these arguments, he is not in agreement with the governmental plan for the development of wind-turbine produced electricity. It is suggested that this plan could be postponed until such time as wind-power produced electricity should be more competitive in price, and that it should not be pursued during a period of economic recession.

  12. Path planning and energy management of solar-powered unmanned ground vehicles (United States)

    Kaplan, Adam

    Many of the applications pertinent to unmanned vehicles, such as environmental research and analysis, communications, and information-surveillance and reconnaissance, benefit from prolonged vehicle operation time. Conventional efforts to increase the operational time of electric-powered unmanned vehicles have traditionally focused on the design of energy-efficient components and the identification of energy efficient search patterns, while little attention has been paid to the vehicle's mission-level path plan and power management. This thesis explores the formulation and generation of integrated motion-plans and power-schedules for solar-panel equipped mobile robots operating under strict energy constraints, which cannot be effectively addressed through conventional motion planning algorithms. Transit problems are considered to design time-optimal paths using both Balkcom-Mason and Pseudo-Dubins curves. Additionally, a more complicated problem to generate mission plans for vehicles which must persistently travel between certain locations, similar to the traveling salesperson problem (TSP), is presented. A comparison between one of the common motion-planning algorithms and experimental results of the prescribed algorithms, made possible by use of a test environment and mobile robot designed and developed specifically for this research, are presented and discussed.

  13. PLAN 94. Costs for management of the radioactive waste from nuclear power production

    International Nuclear Information System (INIS)

    SKB prepares every year, on behalf of the nuclear power utilities, a calculation of the costs for all the measures that are required to manage the spent nuclear fuel from the reactors and the radioactive waste deriving from it and to decommission and dismantle the reactor plants. The cost calculation is submitted to the Nuclear Power Inspectorate (SKI). SKI uses this as a basis for calculating a proposal for the fee for management of the radioactive waste products of nuclear power that is levied on nuclear-generated electricity. The calculation, which is based on specific scenarios for energy production, waste quantities and required measures, are presented in annually issued reports, the last one PLAN 94, dated June 1994. PLAN 93 was a comprehensive report giving an overview of the Swedish radioactive waste management system. The 1994 status regarding general premises, facilities, systems, RD and D, etc., differs only slightly from 1993, and the present English edition of PLAN 94 has therefore been reduced to include only an updated set of those tables and other significant data that were included in PLAN 93. The reader is kindly advised to consider the present report as an addendum to PLAN 93. 7 refs, 2 figs, 13 tabs

  14. Tactical supply chain planning for a forest biomass power plant under supply uncertainty

    International Nuclear Information System (INIS)

    Uncertainty in biomass supply is a critical issue that needs to be considered in the production planning of bioenergy plants. Incorporating uncertainty in supply chain planning models provides improved and stable solutions. In this paper, we first reformulate a previously developed non-linear programming model for optimization of a forest biomass power plant supply chain into a linear programming model. The developed model is a multi-period tactical-level production planning problem and considers the supply and storage of forest biomass as well as the production of electricity. It has a one-year planning horizon with monthly time steps. Next, in order to incorporate uncertainty in monthly available biomass into the planning, we develop a two-stage stochastic programming model. Finally, to balance the risk and profit, we propose a bi-objective model. The results show that uncertainty in availability of biomass has an additional cost of $0.4 million for the power plant. Using the proposed stochastic optimization model could reduce this cost by half. - Highlights: • Developed a two-stage stochastic optimization model to consider supply uncertainty. • Maximized the profit of a forest biomass power plant value chain. • Minimized two risk measures, variability index and downside risk, to manage risks. • Stochastic optimization model provided feasible solution for all scenarios. • Results showed a trade-off between profit and risk management

    Within the BE5935 joint project of the Commission of the European Communities and European industry a new concept of advanced multi-criteria decision making (MCDM) has been developed and applied onto several selected practical problems (bridges, offshore structures, power plants). The example in the area of power plants concerns the planning of periodic inspections (overhauls). The paper describes the concept as applied and customized for power plant related practical applications, and presents the results obtained in 1994 and early 1995. The results confirm the high relevance of the concept for the practice. (author). 6 refs., 1 figs., 4 tabs

  20. Factor analysis for imperfect maintenance planning at nuclear power plants by cognitive task analysis

    International Nuclear Information System (INIS)

    Imperfect maintenance planning was frequently identified in domestic nuclear power plants. To prevent such an event, we analyzed causal factors in maintenance planning stages and showed the directionality of countermeasures in this study. There is a pragmatic limit in finding the causal factors from the items based on report descriptions. Therefore, the idea of the systemic accident model, which is used to monitor the performance variability in normal circumstances, is taken as a new concept instead of investigating negative factors. As an actual method for analyzing usual activities, cognitive task analysis (CTA) was applied. Persons who experienced various maintenance activities at one electric power company were interviewed about sources related to decision making during maintenance planning, and then usual factors affecting planning were extracted as performance variability factors. The tendency of domestic events was analyzed using the classification item of those factors, and the directionality of countermeasures was shown. The following are critical for preventing imperfect maintenance planning: the persons in charge should fully understand the situation of the equipment for which they are responsible in the work planning and maintenance evaluation stages, and they should definitely understand, for example, the maintenance bases of that equipment.

  1. Participation of the ININ in the external radiological emergency plan of the Laguna Verde power plant

    International Nuclear Information System (INIS)

    The planning of performances in radiological emergencies, with the object of reducing the consequences as much as possible on the population to accidental liberations of radioactive material coming from Nuclear power plant, it has been of main interest in the nuclear community in the world. In Mexico it has not been the exception, since with the setting in march of the Laguna Verde nuclear power plant exists an executive program of planning for emergencies that it outlines the activities to follow trending to mitigate the consequences that are derived of this emergency. As integral part of this program this the External Plan of Radiological Emergency (PERE) that covers the emergencies that could leave the frontiers of the Laguna Verde power plant.

  2. Nuclear power plants in Europe 1995. Report about operation, construction, and planning in 18 European countries

    International Nuclear Information System (INIS)

    Report about Operation, Construction, and Planning in 18 European Countries Eighteen European countries operate and build, respectively, nuclear power plants in 1995. The ''Nuclear Power Plants in Europe 1995'' atw report singles out the main events and lines of development. As per August 1995, 214 (1994: 215) nuclear generating units (which means power reactors for the purposes of this report) with an aggregate 177,010 (176,322) MWe installed gross capacity are in operation in seventeen countries, and 26 (30) units with 24,786 (28,086) MWe are under construction in seven countries. This adds up to a total of 240 (245) nuclear generating units with an aggregate 201,796 (204,408) MWe. In the nuclear power plants in Europe, some 1048 TWh of nuclear power was converted into electric power in 1994; 792 TWh of this aggregate was converted in 137 units in the European Union (EU). In the EU the share of nuclear power in the public supply of electricity was 36%. Lithuania, with 77%, has the highest share of nuclear power in Europe, followed by France with 75% and Belgium with 56%. The lowest percentage, only 5%, is recorded in the Netherlands. As a consequence of electricity imports, nuclear power holds considerable shares in the public electricity supply also of countries in which no nuclear power plants are operated, such as Italy or Austria.

    DEFF Research Database (Denmark)

    Anvari-Moghaddam, Amjad; Dragicevic, Tomislav; Meng, Lexuan;


    Next generation power management at all scales is highly relying on the efficient scheduling and operation of different energy sources to maximize efficiency and utility. The ability to schedule and modulate the energy storage options within energy systems can also lead to more efficient use of the...... generating units. This optimal planning and operation management strategy becomes increasingly important for off-grid systems that operate independently of the main utility, such as microgrids or power systems on marine vessels. This work extends the principles of optimal planning and economic dispatch...... problems to shipboard systems where some means of generation and storage are also schedulable. First, the question of whether or how much energy storage to include into the system is addressed. Both the storage power rating in MW and the capacity in MWh are optimized. Then, optimal operating strategy for...

  4. Nuclear power as an option in electrical generation planning for Croatia

    International Nuclear Information System (INIS)

    The expected increase of electricity consumption in the next two decades, if covered mainly by domestic production, will require roughly 4500 MW of new installed capacity. The question is which resource mix would be optimal for the future power plants. Taking into account lack of domestic resources for electricity generation, current trends in the European energy markets, and environmental impact of various energy technologies, it seems reasonable for Croatia to keep the nuclear option open in the future energy planning. In line with that conclusion, this paper analyzes how the introduction of nuclear power plants would influence future power system expansion plans in Croatia, and the possibility to meet the Kyoto requirement. The effects of CO2 emission tax and external costs on the optimal capacity mix and the emissions levels are also examined. (author)

  5. Interesting tools for the cybersecurity plan of a nuclear power plant

    International Nuclear Information System (INIS)

    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.

  6. An investigation on the impacts of regulatory interventions on wind power expansion in generation planning

    International Nuclear Information System (INIS)

    Large integration of intermittent wind generation in power system has necessitated the inclusion of more innovative and sophisticated approaches in power system investment planning. This paper presents a novel framework on the basis of a combination of stochastic dynamic programming (SDP) algorithm and game theory to study the impacts of different regulatory interventions to promote wind power investment in generation expansion planning. In this study, regulatory policies include Feed-in-Tariff (FIT) incentive, quota and tradable green certificate. The intermittent nature and uncertainties of wind power generation will cause the investors encounter risk in their investment decisions. To overcome this problem, a novel model has been derived to study the regulatory impacts on wind generation expansion planning. In our approach, the probabilistic nature of wind generation is modeled. The model can calculate optimal investment strategies, in which the wind power uncertainty is included. This framework is implemented on a test system to illustrate the working of the proposed approach. The result shows that FITs are the most effective policy to encourage the rapid and sustained deployment of wind power. FITs can significantly reduce the risks of investing in renewable energy technologies and thus create conditions conducive to rapid market growth. - Highlights: → The impacts of regulatory policies to promote wind power investment are investigated. → These policies include Feed-in-Tariff (FIT), quota and tradable green certificate. → Result shows that FIT is an effective policy to motivate the rapid growth of wind power. → In quota, customers are forced to provide the quota decided by regulators from wind.

  11. Hybrid power markets in Africa: Generation planning, procurement and contracting challenges

    International Nuclear Information System (INIS)

    African power sectors are generally characterised by insufficient generation capacity. Reforms to address poor performances in the 1990s followed a prescribed evolution towards power markets that would allow wholesale competition amongst generators and so lead towards efficiency improvements. Despite reforms being embarked, competitive power markets have not been established in Africa; rather, the result has been the emergence of hybrid markets where state-owned generators and IPPs operate devoid of competition; and although IPPs have emerged in a number of African power sectors, many countries still do not have sufficient generation to meet their electricity demands. This paper investigates the development of private generation power projects in Africa by analysing data collected from both primary and secondary sources in four case studies of power sectors in Ghana, Cote d'Ivoire, Morocco and Tunisia. It identifies how planning and procurement challenges have lead to difficulties in adding sufficient generation capacity in a timely manner, exacerbating the problem of insufficient generation capacity in Africa. It provides suggestions as to how these frameworks could respond more effectively to the capacity challenges faced by hybrid electricity generation markets, and how broader power sector reforms should be guided to reflect the challenges of hybrid markets better. - Research highlights: → The standard model of power sector reform should no longer be used as a progress measure of power sector development in Africa and many other developing countries. → The hybrid market should in itself be recognised as an established 'model' of power sectors in Africa and many developing countries. → Planning, procurement and contracting arrangements should be shaped specifically for hybrid markets in order to address the problem of insufficient generation capacity in developing countries.

  12. An integrated GIS environment enhancing the operation and planning of power utilities

    International Nuclear Information System (INIS)

    The evolution of electrical power systems was tightly geared by the development of two fields: power engineering, with the advanced technology of physical elements comprising all parts of a power system, and information processing tools to manage the performance of electric power utilities. Compared to power engineering that has gone through tremendous developments, information technology applications for electrical power systems are relatively young. The possible improvements of these applications are in their graphical, mapping an data analysis capabilities. State-of-the art information technology such as Geographic Information Systems provides these facilities. The objective of this thesis is to devise a technique that combines power system software tools with the Geographic Information Systems software to enhance the operation, control and planning of electrical transmission systems. The load flow, voltage control and fault analysis models for the transmission system will be re-engineered in a Geographic Information System environment.The research is generic, special attention is given to its application to the Lebanese electrical power system, which is recovering from an infrastructure devastating war. The research entails integrating power systems analysis and control package, or PSACP developed at the AUB within a Geographic Information Systems environment. This will enhance the power modeling capabilities by the use of powerful thematic mapping, geographic and data analysis and user interface techniques that come with Geographic Information Systems. An overview of the two technologies involved is presented, followed by a detailed description of the integration technique before describing the integrated system. Moving to a higher level, the features of the system are presented, followed by sample applications of the integrated system on the Lebanese electrical power system. The thesis contributes to the research arena by developing a software re

    Haubrich, H.J.; Flechner, B.; Hartenstein, R.; Wolter, H.


    Cost-effective, reliable operation of power supply systems requires foresighted planning. In power plant operation planning the crucial planning term is considered to be one year because it involves making important, commiting decisions which must hold against a great many unpredictable influences. The present paper gives an overview of a three-year research project carried out at the Institute for Electric Installations and Energy Economy of RWTH Aachen (Aachen University of Technology), which had been commissioned by Energie-Versorgung Schwaben AG (EVS) to determine the required modeling accuracy in power plant operation planning and the possibilities of and limits to using computer-aided methods for this purpose. (orig.) [Deutsch] Der kostenguenstige und zuverlaessige Betrieb von Energieversorgungssystemen erfordert eine vorausschauende Planung.

  14. Problems in planning the early closure of the Ignalina nuclear power plant

    International Nuclear Information System (INIS)

    The Ignalina nuclear power plant is the main electricity generator in Lithuania. Having two RBMK-1500 type reactors has meant that the country has the highest per capita nuclear electricity fraction (more than 70%). The design life of each reactor was 30 years of operation, with fuel channel renewal at mid-life. On this basis, Ignalina Unit 1 should have operated until 2013, and Unit 2 up to 2017 (note that the Russian Federation has already announced a 15 year life extension for the similar type Leningrad-1 nuclear power plant). The early closure of Ignalina was finalized in an additional protocol to the Accession Treaty of Lithuania to the European Union. The protocol committed Lithuania to close Unit 1 of the Ignalina plant before 2005 and Unit 2 by the end of 2009, and committed the European Union to provide appropriate funding. The first unit was permanently shut down on 31 December 2004. Decommissioning planning started with the preparation of the Preliminary Decommissioning Plan in 1999; the preparation of legal acts began at the same time. Several legal documents regulating the decommissioning of the Ignalina nuclear power plant and the management of the resulting radioactive waste have since been adopted. The adoption of the Final Decommissioning Plan and the selection of the decommissioning strategy have their own history and outcomes, as described in the paper. The paper also deals with decommissioning financing, problems encountered in the planning process, social measures and local economic regeneration, and lessons learned. (author)

  15. Environmental valuation for long-term strategic planning. The case of the Brazilian power sector

    International Nuclear Information System (INIS)

    If not properly dealt with over compatible horizons, environmental issues may cause ventures to incur higher costs and extend over longer implementation periods. Prompted by the uncertainties and risks inherent in these issues, as well as by the need for long-term plans to incorporate sustainable development principles, the Brazilian Power Sector is encouraging the inclusion of environmental aspects as a decision variable right from the start of the planning cycle. The purpose of this paper is to bolster efforts to include in this sector's expansion plans, costs resulting from environmental degradation of the environment. The paper offers an overview of the methodology developed to assess and include in long-term planning for this sector, external environmental costs linked to hydro-power and thermo-power generation. It suggests the use of environmental economic valuation techniques a practice commonly used to analyze the degradation of natural capital in various countries as well as assessing projects and programs, adopting the premises and simplifications required for application over the longer term.21 refs

  16. Modeling the effects of demand response on generation expansion planning in restructured power systems

    Institute of Scientific and Technical Information of China (English)

    Mahdi SAMADI; Mohammad Hossein JAVIDI; Mohammad Sadegh GHAZIZADEH


    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.

  17. Report to Congress on status of emergency response planning for nuclear power plants

    International Nuclear Information System (INIS)

    This report responds to a request (Public Law 96-295, Section 109) for the Nuclear Regulatory Commission (NRC) to report to Congress on the status of emergency response planning in support of nuclear power reactors. The report includes information on the status of this planning as well as on the Commission actions relating to emergency preparedness. These actions include a summary of the new regulatory requirements and the preliminary results of two comprehensive Evacuation Time Estimate studies; one requested by the NRC including 50 nuclear power plant sites and one conducted by the Federal Emergency Management Agency (FEMA) for 12 high population density sites. FEMA provided the information in this report on the status of State and local planning, including projected schedules for joint State/county/licensee emergency preparedness exercises. Included as Appendicies are the NRC Emergency Planning Final Regulations, 10 CFR Part 50 (45 FR 55402), the FEMA Proposed Rule, 'Review and Approval of State and Local Radiological Emergency Plans and Preparedness', 44 CFR Part 350 (45 FR 42341) and the NRC/FEMA Memorandums of Understanding

  18. Dose assessment for setting of EPZ in emergency plan for decommissioning of nuclear power plant

    International Nuclear Information System (INIS)

    In emergency plan for a nuclear power plant, taking enough measures in EPZ boundary (Emergency Planning Zone) is one of priority matters, to have protection against the release of radioactive materials in accident efficiently and quickly to minimize environmental impacts. EPZ is set as the zone which emergency plans should be mainly prepared on emergency conditions. The criteria of EPZ is that dose value in the area between plant and EPZ boundary have to be less than 10 mSv, even if very conservative release mechanisms and path are supposed. The released amount of radioactive material from a nuclear power plant is calculated to the accident scenario were supposed with the each phase of decommissioning. Moreover, the dose value is calculated as the evaluation of environmental impacts, using atmospheric diffusion parameters are determined by the plume concentration Gaussian type distribution model at steady state, and annual meteorological data of the reference plants. Both of 'the spent fuel storage phase' and 'the safe maintenance and dismantling phase' on each of the expected accident scenario, the dose value in EPZ boundary is much less than safety criteria (10 mSv), and there is no need to plan offsite emergency plan, such as the Sheltering and Escape for a reference plant. This result is agreeing with the opinion of Waste and decommission working group 2006 of Western European Nuclear Regulator's Association (WENRA). (author)

  19. Integrated generation and transmission expansion planning including power and fuel transportation constraints

    International Nuclear Information System (INIS)

    This paper presents a comprehensive optimal expansion planning model for an integrated generation and transmission system. The objective function used in the optimization model comprises of the capital cost of the new generating units to be built, the fuel cost incurred in running all the generating units in the system including the transportation cost of fuel from the fuel source ends to the generating unit locations and the capital cost of the new transmission lines to be installed for meeting the forecasted system demand at the target planning year. Constraints taken care of in the model include the fuel availability limits at the fuel sources, the fuel transportation limits for the transportation of fuels from fuel sources to the generating unit locations, capacity of generating units required to be built as well as the power transmission limits of the transmission lines in the system. The developed model is tested on a system to bring out the relative advantage of adopting the integrated generation and transmission expansion planning approach as compared to the sequential approach of first planning the generation expansion and then the transmission expansion. The model has also been applied to the integrated generation and transmission expansion planning of a real system. - Highlights: ► Integrated generation and transmission expansion planning model has been developed. ► Fuel transportation routes and power transmission network have been considered. ► Power flow over transmission lines have been modeled considering both Kirchoff’s laws. ► Electricity production and supply chain has been optimized.

    Directory of Open Access Journals (Sweden)

    Habib H. Al-Ali


    Full Text Available In this study, electricity production from a network of coal power plants and under environmental constraints is considered. Several pollutants are incorporated into the decision planning process including nitrogen oxides (NOx, sulfur oxides (SOx and mercury (Hg. A Nonconvex Mixed Integer Nonlinear Programming (MINLP model was first developed to assist in the evaluation process. An exact linearization of the nonconvex terms was then derived to reformulate the MINLP model into a mixed integer linear program (MILP. Several scenarios of electricity production planning and emission reduction targets are analyzed on a representative case study.

  3. Optimal reactive power planning for distribution systems considering intermittent wind power using Markov model and genetic algorithm (United States)

    Li, Cheng

    Wind farms, photovoltaic arrays, fuel cells, and micro-turbines are all considered to be Distributed Generation (DG). DG is defined as the generation of power which is dispersed throughout a utility's service territory and either connected to the utility's distribution system or isolated in a small grid. This thesis addresses modeling and economic issues pertaining to the optimal reactive power planning for distribution system with wind power generation (WPG) units. Wind farms are inclined to cause reverse power flows and voltage variations due to the random-like outputs of wind turbines. To deal with this kind of problem caused by wide spread usage of wind power generation, this thesis investigates voltage and reactive power controls in such a distribution system. Consequently static capacitors (SC) and transformer taps are introduced into the system and treated as controllers. For the purpose of getting optimum voltage and realizing reactive power control, the research proposes a proper coordination among the controllers like on-load tap changer (OLTC), feeder-switched capacitors. What's more, in order to simulate its uncertainty, the wind power generation is modeled by the Markov model. In that way, calculating the probabilities for all the scenarios is possible. Some outputs with consecutive and discrete values have been used for transition between successive time states and within state wind speeds. The thesis will describe the method to generate the wind speed time series from the transition probability matrix. After that, utilizing genetic algorithm, the optimal locations of SCs, the sizes of SCs and transformer taps are determined so as to minimize the cost or minimize the power loss, and more importantly improve voltage profiles. The applicability of the proposed method is verified through simulation on a 9-bus system and a 30-bus system respectively. At last, the simulation results indicate that as long as the available capacitors are able to sufficiently

    International Nuclear Information System (INIS)

    Highlights: ► Power system security of different load points is considered in the generation expansion planning problem. ► A modified game theory is proposed to evaluate the contrast of generation companies by independent system operator. ► The reliability of all load points is optimized based on the availability of the composite power system. ► A dynamic programming method is used to find the best solution of GENCOs for decision making of investment. - Abstract: One of the main challenges of restructured power systems is to maintain sufficient installed generation capacity to meet system demand in different load points of transmission network both for present and future time. This paper presents a comprehensive Generation Expansion Planning (GEP) scheme in pool market, ensuring secure operation of power system in different load points. The proposed algorithm is divided into two programming levels: master and slave. In the master level, a Modified Game Theory (MGT) is proposed to evaluate the contrast of generation companies (GENCOs) by Independent System Operator (ISO). Besides that, the reliability level of all load points is optimized based on the availability of the composite power system, i.e. generation and transmission level. In the slave level, a Dynamic Programming (DP) method is used to find the best solution of each GENCO for decision making of investment. The validity of the proposed GEP is studied on Roy Billinton Test System (RBTS).

    Indian Academy of Sciences (India)

    P K Vijayan; M T Kamble; A K Nayak; K K Vaze; R K Sinha


    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.

  9. Energy and environmental studies associated to the emergency plan of natural gas thermal power plants

    International Nuclear Information System (INIS)

    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.

  10. Improvements in in-bay irradiated fuel inspection planning and analysis at Bruce Power

    International Nuclear Information System (INIS)

    This paper describes improvements in irradiated fuel inspection planning and analysis implemented at Bruce Power since 2012. A review of inspection plans and fuel performance reports since 2001 identified significant variations in how irradiated fuel bundles were selected for inspection from year-to-year. A series of inspection tasks was established in an inspection logic and technical basis document. Inspection objectives and bundle selection criteria were defined for each task. These requirements, along with resource availability are now used to prepare a fuel inspection plan each year. The inspection results are then considered in the context of the analysis objectives for each task. The inspection results are presented in brief monthly updates and in-depth semi-annual reports in addition to the Annual Fuel Performance Reports. These changes have improved the effectiveness, consistency and efficiency of Bruce Power’s fuel performance monitoring. (author)

  11. Medical emergency planning in case of severe nuclear power plant accidents

    International Nuclear Information System (INIS)

    This paper is an attempt to discuss a three-step-plan on medical emergency planning in case of severe accidents at nuclear power plants on the basis of own experiences in the regional area as well as on the basis of recommendations of the Federal Minister of the Interior. The medical considerations take account of the severity and extension of an accident whereby the current definitions used in nuclear engineering for accident situations are taken as basis. A comparison between obligatory and actual state is made on the possibilities of medical emergency planning, taking all capacities of staff, facilities, and equipment available in the Federal Republic of Germany into account. To assure a useful and quick utilization of the existing infra-structure as well as nation-wide uniform training of physicians and medical assistants in the field of medical emergency in case of a nuclear catastrophe, a federal law for health protection is regarded urgently necessary.

  13. Power system generation expansion planning using the maximum principle and analytical production cost model

    International Nuclear Information System (INIS)

    Historically, the electric utility demand in most countries has increased rapidly, with a doubling of approximately 10 years in the case of developing countries. In order to meet this growth in demand, the planners of expansion policies were concerned with obtaining expansion pans which dictate what new generation facilities to add and when to add them. This paper reports that, however, the practical planning problem is extremely difficult and complex, and required many hours of the planner's time even though the alternatives examined were extremely limited. In this connection, increased motivation for more sophisticated techniques of valuating utility expansion policies has been developed during the past decade. Among them, the long-range generation expansion planning is to select the most economical and reliable generation expansion plans in order to meet future power demand over a long period of time subject to a multitude of technical, economical, and social constraints

  14. Augmented reality for improved communication of construction and maintenance plans in nuclear power plants

    International Nuclear Information System (INIS)

    The purpose of implementing Augmented Reality, AR, in the planning, construction and maintenance of Nuclear Power Plants is to secure strict control, precise and correct constructions, exact execution of assignments and heightened safety at all levels. Communication of construction plans to ensure precise and correct assembly of structural elements is essential in all building projects. This is especially crucial in the construction of nuclear plants and installation of new components. The current ways in which construction plans are communicated, blueprints, 3D digital models and written descriptions all embody the need for significant levels of abstraction and interpretation, and are thus both difficult to understand and can lead to misinterpretations. A simulation system with full scale three dimensional models experienced in the physical setting where operations are to take place would bring operators closer to the real life assignments. Augmented Reality is a visualization technology that provides this motivation. (author)

The forecasting methodology presented in the paper combines the powe...

  20. Generation Planning Methodology Based on Load Factor for Hydroelectric Power Plants


    Süleyman Hakan Sevilgen; Hasan Hüseyin Erdem


    Major parameters affecting the generation capacity of hydroelectric plants are resource regime, reservoir geometry, and water head together with flow rate and efficiency. For the same resource regime and flow rate, water head can be altered depending on generation planning. By means of holding water in the reservoir and consequent increase in head can lead to boost power generation. In this paper, a method to compare two different operational styles has been identified; a plant operating with...

  1. Launching and implementing FEMP`s 1997 outreach plan featuring the ``You Have the Power`` campaign

    Energy Technology Data Exchange (ETDEWEB)



    The Federal Energy Management Program`s (FEMP`s) mission is to help Federal agencies reduce energy costs by delivering effective technology transfer and outreach programs. It is important that FEMP provide leadership and good examples to the Federal sector so that FEMP`s programs and priorities can be transferred throughout Federal agencies and offices across the Nation. In order to achieve this mission, FEMP must send a clear message to everyone involved with the management of Federal facilities concerning its available resources, effective information and assistance, educational programs, tools, and training. 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.

  2. Explaining wind power planning outcomes: some findings from a study in England and Wales

    International Nuclear Information System (INIS)

    This paper discusses the factors that influence the outcome of onshore windfarm planning application in England and Wales. Various qualitative and quantitative methods have been employed, including regression analysis. Strong associations have been discovered between the outcome of local authority planning decisions, the opinions of local planning officers, the opinions of parish councils where the proposed windfarms are to be sited and the opinions of landscape protection groups. The attitude of people in the immediate vicinity of proposed windfarms is found to be the most important influence on the decisions made by local authorities. However, the local perception of the economic impact is of crucial importance in forming this judgement, as is the national political environment. The expected attitude of Appeal Inspectors is also important. It is concluded that there is a lot that wind power developers could do to improve the prospects of planning success. This includes engaging in local 'parish council' politics, talking to the closest residents to proposed schemes and encouraging local pro-wind power campaigns. Future projects are likely to be favoured by installing viewing towers at the tops of turbines to encourage visitors and in selling shares in the schemes to local people

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

    Fripp, Matthias


    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.

  4. The outline of decommissioning plan for Hamaoka Nuclear Power Station's Unit 1 and Unit 2

    International Nuclear Information System (INIS)

    In Japan, terminated nuclear power stations must be dismantled and removed, and doing this requires establishing a nuclear reactor facility decommissioning plan as based on the Law on the Regulation of Nuclear Source Material, Nuclear Fuel Material and Reactors, and getting the approval of the national government. Termination Hamaoka Nuclear Power Station's Unit 1 and Unit 2 on January 30, 2009 Chubu Electric submitted an 'Application for Approval of Hamaoka Nuclear Power Station's Unit 1 and Unit 2 Decommissioning Plan' to the Minister of Economy, Trade and Industry in keeping with the stipulations of Article 43, Paragraph 3-2-2, of the Law on the Regulation of Nuclear Source Material, Nuclear Fuel Material and Reactors. On June 1, 2009 As the application was authorized on November 18, 2009, Chubu Electric started to dismantle. The application includes an overall plan for dismantling reactor facilities safely and surely, a description of tasks to be performed during the period Chubu Electric is preparing to dismantle the facilities in the coming years (system decontamination, survey of facility contamination, etc.) and safety assurance measures, among other information.

  5. Genetic algorithms for optimal reactive power compensation planning on the national grid system (United States)

    Pilgrim, J. D.

    This work investigates the use of Genetic Algorithms (GAs) for optimal Reactive power Compensation Planning (RCP) of practical power systems. In particular, RCP of the transmission system of England and Wales as owned and operated by National Grid is considered. The GA is used to simultaneously solve both the siting problem---optimisation of the installation of new devices---and the operational problem---optimisation of preventive transformer taps and the controller characteristics of dynamic compensation devices. A computer package called Genetic Compensation Placement (GCP) has been developed which uses an Integer coded GA (IGA) to solve the RCP problem. The RCP problem is implemented as a multi-objective optimisation: in the interests of security, the number of system and operational constraint violations and the deviation of the busbar voltages from the ideal are all minimised for the base (intact) case and the contingent cases. In the interests of cost reduction, the reactive power cost is minimised for the base case. The reactive power cost encompasses the costs incurred from the installation of reactive power sources and the utilisation of new and existing dynamic reactive power compensation devices. GCP is compared to SCORPION (a planning program currently being used by National Grid) which uses a combination of linear programming and heuristic back-tracking. Results are presented for a practical test system developed with the cooperation of National Grid, and it is found that GCP produces solutions that are cheaper than solutions found by SCORPION and perform extremely well: an improvement in voltage profiles, a decrease in complex power mismatches, and a reduction in MVolt Amps-reactive (VAr) utilisation were observed.

  7. Problems of heat sources modeling on stage of isolated power systems expansion planning

    International Nuclear Information System (INIS)

    It is necessary to use computer codes for evaluation of possible applications and role of nuclear district heating plants in the local self-balancing power and heating systems, which are to be located in the remote isolated and hardly accessible regions in the Far North of Russia. Key factors in determining system configurations and its performances are: (1) interdependency of electricity, heat and fuel supply; (2) long distance between energy consumer centres (from several tens up to some hundred kilometers); and (3) difficulty in export and import of the electricity, especially the fuel in and from neighbouring and remote regions. The problem to challenge is to work out an optimum expansion plan of the local electricity and heat supply system. The ENPEP (ENergy and Power Evaluation Program) software package, which was developed by IAEA together with the USA Argonne National Laboratory, was chosen for this purpose. The Chaun-Bilibino power system (CBPS), an isolated power system in far North-East region of Russia, was selected as the first case of the ENPEP study. ENPEP allows a complex approach in the system expansion optimization planning in the time frame of planning period of up to 30 years. The key ENPEP module, ELECTRIC, considers electricity as the only product. The cogeneration part (heat production) must be considered outside the ELECTRIC model and then the results to be transfer ed to ELECTRIC. The ENPEP study on the Chaun-Bilibino isolated power system has shown that the modelling of the heat supply sources in ENPEP is not a trivial problem. It is very important and difficult to correctly represent specific features of cogeneration process at the same time. (author)

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

  9. Bias present in US federal agency power plant CO2 emissions data and implications for the US clean power plan (United States)

    Gurney, K. R.; Huang, J.; Coltin, K.


    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.

  10. Appendix XXIV: Human resource planning and training for nuclear power projects in CPI

    International Nuclear Information System (INIS)

    China Power Investment Corporation (CPI) is one of the five largest state-owned power generation groups in China with controllable installed capacity of 28,000 MW(e) and 70,000 staff. CPI owns shares of five operating NPPs and four new planed NPP projects. CPI is also working on preparations for new in-land NPP projects. At present, CPI is investing in, with major shares, and developing Shangdong Haiyang NPP and Liaoning Hongyanhe NPP projects. Based on demands on nuclear professionals and very limited human resources available in China, a plenty of professionals from conventional power industry, the strategy of human resource planning for CPI's nuclear projects is defined as 'Introduction from outside, while mainly reliance on training by CPI'. That is, on one hand, to directly introduce experienced nuclear professionals, and on the other hand, to train and strengthen the prominent staff with rich construction and operation experience in conventional plants, in nuclear construction, operation and management

  11. Stages in planning and construction of the Muelheim-Kaerlich nuclear power station

    International Nuclear Information System (INIS)

    On October 23, 1972, RWE gave a letter of intent and on January 9, 1973 an order for the construction of a nuclear power plant on a turn-key basis to the consortium of BBC, BBR and Hochtief. The power plant in question was the Muelheim-Kaerlich nuclear power station with a pressurized-water reactor of a gross efficiency of 1,295 MWe. After considerable delay of the project, the first building permit was issued to the builder-owner on January 15, 1975, and the constructional work on the building site started immediately afterwards. As the planning and constructional work has so far been carried out according to schedule and the consortium intends to keep the effects of the belated license as small as possible, the start-off of the plant will probably be in summer 1979 if the constructional work is not interrupted.

  12. Nuclear Power Safety Reporting System implementation plan, concept evaluation and operability test

    International Nuclear Information System (INIS)

    During the 1984 fiscal year, the Aerospace Corporation continued to assist the US Nuclear Regulatory Commission (NRC) in evaluating the concept of a Nuclear Power Safety Reporting System (NPSRS). The NPSRS concept embodies a voluntary, nonpunitive, third party managed human factors data gathering system that (with the NRC as its parent agency) could be used for identifying and quantifying factors that contribute to the occurrence of safety problems involving personnel in nuclear power plants. NPSRS data could be used to: (1) support efforts to quantify the human reliability elements of probabilistic risk assessments (PRA's); (2) to evaluate the influence of various nuclear power plant systems on human error-proneness within the system; and (3) to aid in the development of design criteria for human-machine safety systems. The draft implementation plan and a description of the operability demonstration test have been published. Progress toward initiating the actual test is reported as are issues yet to be resolved

  13. Geothermal power plants of the United States: a technical survey of existing and planned installations

    Energy Technology Data Exchange (ETDEWEB)

    DiPippo, R.


    The development of geothermal energy as a source of electric power in the United States is reviewed. A thorough description is given of The Geysers geothermal power project in northern California. The recent efforts to exploit the hot-water resources of the Mexicali-Imperial Rift Valley are described. Details are given concerning the geology of the several sites now being used and for those at which power plants will soon be built. Attention is paid to the technical particulars of all existing plants, including wells, gathering systems, energy conversion devices, materials, environmental impacts, economics and operating characteristics. Specifically, plants which either exist or are planned for the following locations are covered: The Geysers, CA; East Mesa, CA; Heber, CA; Roosevelt Hot Springs, UT; Valles Caldera, NM; Salton Sea, CA; Westmorland, CA; Brawley, CA; Desert Peak, NV; and Raft River, ID. The growth of installed geothermal electric generating capacity is traced from the beginning in 1960 and is projected to 1984.

  14. Tradeoffs in the design of health plan payment systems: Fit, power and balance. (United States)

    Geruso, Michael; McGuire, Thomas G


    In many markets, including the new U.S. Marketplaces, health insurance plans are paid by risk-adjusted capitation, sometimes combined with reinsurance and other payment mechanisms. This paper proposes a framework for evaluating the de facto insurer incentives embedded in these complex payment systems. We discuss fit, power and balance, each of which addresses a distinct market failure in health insurance. We implement empirical metrics of fit, power, and balance in a study of Marketplace payment systems. Using data similar to that used to develop the Marketplace risk adjustment scheme, we quantify tradeoffs among the three classes of incentives. We show that an essential tradeoff arises between the goals of limiting costs and limiting cream skimming because risk adjustment, which is aimed at discouraging cream-skimming, weakens cost control incentives in practice. A simple reinsurance system scores better on our measures of fit, power and balance than the risk adjustment scheme in use in the Marketplaces. PMID:26922122

  15. Power Demand Forecasting Methodology as a Tool For Planning and Development of the Distribution Networks

    Directory of Open Access Journals (Sweden)

    Jarosław G. Korpikiewicz


    Full Text Available Planning for the development of the distribution network, providing the required level of reliability, while minimizing expenditures for the expansion requires forecasting future demand for power end-users connected to the network. Dynamics of changes in electrical load will depend on many factors, both local (e.g. changes in the structure and number of customers and global (e.g. changes in energy intensity of consumption. The forecasting methodology presented in the paper combines the power demand trend extrapolation techniques, resulting from historical measurement data, with using the information about the potential socio-economic development and available economic and demographic forecasts at different levels of territorial division of the country. Application of the proposed methodology allows performing medium and long term projections of demand for power in the nodes of the distribution network.

  16. National nuclear power plant safety research 2011-2014. SAFIR2014 framework plan

    Energy Technology Data Exchange (ETDEWEB)


    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 employment and the economy appointed a group to write the Framework Plan of the new programme. This report contains a proposal for the general outline of the programme, entitled as SAFIR2014 (SAfety of Nuclear Power Plants - Finnish National Research Programme). The plan has been made for the period 2011-2014, 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 and new decisions-in-principle have also been taken into account in the plan. The safety challenges set by the existing plants and the new projects, 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 new power plant units 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

  17. Pluri-annual planning of power generation investments. 2005-2015 era

    International Nuclear Information System (INIS)

    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.

  18. Ontario's integrated power system plan : discussion paper 3 : conservation and demand management

    International Nuclear Information System (INIS)

    Ontario's Integrated Power System Plan (IPSP) has identified the conservation, generation and transmission investments needed in the next 3 to 5 years to meet Ontario's power requirements. The plan specifies the relative contributions that will be made from conservation and demand management (CDM), renewable generation and conventional sources of supply. The purpose of this CDM discussion paper was to promote engagement from consumers, distributors, generators and transmitters to ensure that their priorities and views are considered in the plan's development. The approach that the Ontario Power Authority (OPA) has taken to address CDM was presented along with the size of the potential CDM resource by customer sector and CDM category. The criteria to be used in building a CDM portfolio was outlined along with the principles used to design, deliver and evaluate individual CDM initiatives. This document also outlined the steps required to establish comprehensive evaluation, measurement and verification procedures to ensure continuous improvement in how the CDM resource is developed. The development of the plan will be shaped by stakeholder comment and advice on key questions from this paper, which ask if the understanding of the CDM challenge is consistent with stakeholders' understanding of the challenge and whether the approach for developing the CDM resource is appropriate for meeting the targets. The paper also questions if the estimates of potential energy savings and demand reduction by economic sector and CDM category are a good starting place for the development of the first IPSP. The CDM consultation process will involve a future workshop for exchanging information. 4 refs., 30 tabs., 9 figs., 3 appendices

  19. Automatic data processing and analysis system for monitoring region around a planned nuclear power plant (United States)

    Kortström, Jari; Tiira, Timo; Kaisko, Outi


    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.

    Faertes, Denise; Vieira, Flavia; Saker, Leonardo; Heil, Luciana [PETROBRAS, Rio de Janeiro, RJ (Brazil); Galvao, Joao [DNV, Rio de Janeiro, RJ (Brazil)


    The purpose of this paper is to present gas allocation plans developed for PETROBRAS Gas and Power Sector, considering failure to supply scenarios that could occur along gas supply network. Those scenarios, as well as the associated contingency plans, were identified and validated by an experienced team, composed by engineers and operators from different PETROBRAS sectors. The key issue of concern was the anticipation of possible undesired scenarios that could imply on contract shortfalls, the evaluation of possible maneuvers, taking into account best gas delivery allocation. Different software were used for the simulation of best gas supply allocation and for the verification of delivery pressure and conditions for final consumers. The ability of being capable of dealing with undesired or crisis scenarios, based on suitable anticipation levels, is, nowadays, a highly valuable attribute to be presented by competitive corporations, for best crisis management and prompt recovery response. Those plans are being used by Gas and Power Gas Operation Control Centre and as an input for reliability modeling of gas supply chain. (author)

    Institute of Scientific and Technical Information of China (English)


    <正>2011 is the first year of the 12th Five-Year Plan, but electric power supply has become a bottleneck of China’s economic development. 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.

  2. Plan 93. Costs for management of the radioactive waste from nuclear power production

    International Nuclear Information System (INIS)

    The Swedish nuclear power utilities are responsible for adopting such measures as are necessary in order to ensure the safe management and disposal of spent nuclear fuel and radioactive waste from the Swedish nuclear power reactors. In order to fulfill this responsibility, the nuclear power utilities have commissioned SKB, the Swedish Nuclear Fuel and Waste Management Co., to plan, build and operate the necessary facilities and systems. This report presents a calculation of the costs for implementing all of these measures. The facilities and systems that exists are: * transportation system for radioactive waste products. * central interim storage facility for spent nuclear fuel, CLAB. * final repository for radioactive operational waste, SFR 1. Future facilities under planning are: * encapsulation plant for spent nuclear fuel, EP. * deep repository for spent fuel and other long-lived waste. * final repository for decommissioning waste. The cost calculations also include costs for research and development, including the Aspo hard rock laboratory, and for decommissioning and dismantling of the reactor plants, etc. The amounts of waste to be handled are dependent upon the total operating time of the nuclear power plant. The total future costs of the Swedish waste management system, commencing from 1994, have been calculated to be SEK 48.3 billion in January 1993 prices considering operation of all reactors up to and including the year 2010. These costs will be incurred over a period of about 60 years. SEK 9.3 billion has been spent up to the end of 1993. In case of 25 or 40 years of reactor operation the total future costs will be SEK 45.9 or 55.5 billion respectively. This cost calculation is presented annually to SKI, the Swedish Nuclear Power Inspectorate, wich uses it as a basis to propose a fee on the nuclear electricity production to cover all future expenses. The fee for 1993 is on average 0.019 SEK/kWh

    This special report, Policy Planning for Nuclear Power: An Overview of the Main Issues and Requirements, has been prepared in response to the express request of a number of IAEA Member States for a document to assist makers in developing countries on the introduction of nuclear power. The report contains information on the political, governmental, economic, financial and technical issues and requirements associated with planning and implementing a safe, economic and reliable nuclear power programme. It highlights the main areas in which policies must be developed and decisions taken, as well as the role and responsibilities of government, the plant owner and national industry. Also presented are the main criteria to assist policy planners in defining options and strategies which can achieve a balance among such objectives as cost effective and efficient electricity production, realistic and acceptable financing arrangements, national development requirements, safety and environmental protection. Further information and details on the technical and other issues presented in this report are given in the list of related IAEA publications and documents at the end of this report

  4. Outage planning in nuclear power plants. A paradigm shift from an external towards an integrated project planning tool

    International Nuclear Information System (INIS)

    Latest demands on nuclear plant inspections are the ongoing actualisation of the outage plan on the basis of the current work progress and current events as well as the permanent access to the current planning status and work process of all people involved in the outage. Modern EAM systems (EAM: Enterprise Application Management) made up ground on established project planning tools with regard to functionalities for scheduling work orders. A shift towards an integrated planning in the EAM system increases the efficiency in the outage planning and improves the communication of current states of planning. (orig.)

  5. Using the ENPEP program for nuclear power planning study in Vietnam

    International Nuclear Information System (INIS)

    In the framework of national R-D project KH-09-04 ''Establishment the fundamental basic for the introduction of nuclear power into Vietnam'', 1996-1998, and Technical cooperation project VIE/0/009 ''Prefeasibility study for the introduction of nuclear power plant into Vietnam'', 1997-1999, planning study of energy and nuclear power has been conducted. Based on 3 scenarios (high, based and low) of the Vietnam socio-economic development up to year 2020, the energy demand (forecasting was carried out using computer model MAED. The electricity demand forecast obtained from the MAED is used as one of the basic inputs to the optimization study of the electricity generating sector using the WASP model. In view of the limited, energy supplies form indigenous resources, it has been assumed that imported coal and nuclear power will be considered as the future energy supply options. From the results of optimal electric system expansion found in the study, it can be concluded that nuclear power should be added to the system from 2016 to 2020 depends on national economic development and availability of domestic natural gas sully (author)

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

    Energy Technology Data Exchange (ETDEWEB)


    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.

  7. Proceedings of the APPrO 2007 19. annual Canadian power conference and networking centre : sharpening the blueprint : how the industry will deliver on Ontario's power plans

    International Nuclear Information System (INIS)

    This conference provided a forum for members of the Association of Power Producers of Ontario to discuss recent developments in electric power management, supply and distribution. The conference included a roundtable of industry experts who discussed major directional issues related to the electric power industry. Industry experts addressed the regulated price plan for residential consumers which is intended to shield consumers from price volatility. While the province plans to shut down all of Ontario's coal-fired generating facilities by 2014, the industry is facing challenges in terms of social judgements on the quality of new proposed projects and their development process. The conference also addressed emerging issues with the integrated power system plan (IPSP) as well as options for new and improved Ontario Power Authority (OPA) procurement mechanisms. Other topics of discussion included Ontario's Clean Energy Standard Offer and Renewable Energy Standard Offer Programs; prospects for competition; transmission planning; securing gas for power generation; First Nations power generation panel; and, technology options for nuclear energy in Ontario. This conference was held in conjunction with the APPrO green power conference. refs., tabs., figs

    and transmission expansion plan that minimizes system-wide investment and operating costs, while ensuring a given share of renewable generation in the electricity supply. Unlike existing ones, this framework includes both a day-ahead and a balancing market so as to capture the impact of both......This paper analyzes the impact of production forecast errors on the expansion planning of a power system and investigates the influence of market design to facilitate the integration of renewable generation. For this purpose, we propose a programming modeling framework to determine the generation...... production forecasts and the associated prediction errors. Within this framework, we consider two paradigmatic market designs that essentially differ in whether the day-ahead generation schedule and the subsequent balancing re-dispatch are co-optimized or not. The main features and results of the model set...

  9. Meteorological aspects of environmental health and safety planning in nuclear power plant sites

    International Nuclear Information System (INIS)

    Micrometeorological data i.e. those dealing with the properties of atmosphere in the first 100 meters or so above the earth's surface are required in planning and control of environmental impact of gaseous effluent releases from a nuclear power plant. Data of various types to be collected during the stages of site survey, site evaluation, normal operation of the plant and accident contigency planning are described. Atmospheric dispersion models in general and one suggested by Pasquill in particular are outlined. These models relate the dispersion parameters to the meteorological observables and are used in evaluating environmental dose. Cautions to be exercised while applying these models to the real situation are mentioned. The use of meteorological data for accident analysis while evaluating plant design parameters is discussed.

    owners are either the grid operators, the generation owners, or the energy traders. For the grid operators being the DES owners, storage operation will have to be integrated into the planning of the system, therefore multivariate nonparametric time series analysis and synthesis methods have to be applied......Stochastic energy flows are an increasingly important phenomenon in today's power system planning and operation. They are – among other reasons – caused by large amounts of stochastic generation such as wind. The inclusion of energy storage devices, distributed in future systems (distributed energy...... storage – DES), is continuously being mentioned as a possibility to alleviate some of the problems arising from stochastic generation. The authors show that the potential ownership of the DES systems is an important criterion on which probabilistic methods will be applied for assessment. The potential...
