  16. The impact of the year 2000 issue on electricity grid performance and nuclear power plant operation in Bulgaria, the Russian Federation and Slovakia

    International Nuclear Information System (INIS)

    1999-07-01

    The Y2K date conversion is a potential source of problems to the operation of nuclear power plants through external events and interfaces with electrical power systems, telecommunication systems, and other supporting infrastructures, even if diagnostic and corrective actions within the plant itself, both planned or implemented, are successful. At the end of 1998 there were 425 nuclear power plants in operation in 31 Member States. Most countries and regions are conducting intensive diagnostic and corrective activities to 'find and fix' Y2K software (including embedded software) and equipment problems in their nuclear power plants. These efforts are supplemented by contingency plans. Other countries and regions have not been making comparable efforts and are relying mainly on contingency planning and preparedness. Results of diagnostic and corrective activities can be of benefit to all Member States. Activities on 'find and fix' Y2K problems in electricity grid control systems and computer related technology in national and regional dispatch centers could be of considerable benefit due to the widespread use of the same components, equipment, and software. Consistent with the objectives of the International Atomic Energy Agency's Y2K program, an experts meeting was convened to collect information on Y2K activities related to grid operation in countries that operate nuclear power plants and also to identify specific actions to be taken and issues to be addressed in connection with expected grid disturbances. The countries of eastern Europe and the Russian Federation were considered to be a very important region due to delays in taking Y2K corrective actions but also due to the similarity of their electricity grid systems both in components and design but also in mode of operation. Most of these countries either operate their own nuclear power plants or are linked through their electricity grid interconnections to a neighboring country that operates nuclear power

    This article takes a look at the chances offered to the electricity supply industry by the increasing use of battery-driven vehicles - and the advantages thus offered to the environment. The use of the vehicles' batteries to form a distributed electricity storage scheme is discussed. The authors comment that, although electrically-driven vehicles consume more power, the total primary energy consumption and pollutant emissions will be reduced. The actual electricity consumption of electric vehicles and the source of this power are examined. Power saved by the reduced use of electrical heating systems and boilers could, according to the authors, be used to charge the batteries of electric vehicles. The use of these batteries as a storage system to help regulate electricity supplies is discussed and the steps to be taken for the implementation of such a system are listed

    1999-01-01

    The National Spherical Torus Experiment (NSTX) has been designed and installed in the existing facilities at Princeton Plasma Physic Laboratory (PPPL). Most of the hardware, plant facilities, auxiliary sub-systems, and power systems originally used for the Tokamak Fusion Test Reactor (TFTR) have been used with suitable modifications to reflect NSTX needs. The design of the NSTX electrical power system was tailored to suit the available infrastructure and electrical equipment on site. Components were analyzed to verify their suitability for use in NSTX. The total number of circuits and the location of the NSTX device drove the major changes in the Power system hardware. The NSTX has eleven (11) circuits to be fed as compared to the basic three power loops for TFTR. This required changes in cabling to insure that each cable tray system has the positive and negative leg of cables in the same tray. Also additional power cabling had to be installed to the new location. The hardware had to b e modified to address the need for eleven power loops. Power converters had to be reconnected and controlled in anti-parallel mode for the Ohmic heating and two of the Poloidal Field circuits. The circuit for the Coaxial Helicity Injection (CHI) System had to be carefully developed to meet this special application. Additional Protection devices were designed and installed for the magnet coils and the CHI. The thrust was to making the changes in the most cost-effective manner without compromising technical requirements. This paper describes the changes and addition to the Electrical Power System components for the NSTX magnet systems

The Electric Power Annual is prepared by the Coal and Electric Data and Renewables Division; Office of Coal, Nuclear, Electric and Alternate Fuels; Energy Information Administration (EIA); U.S. Department of Energy. In the private sector, the majority of the users of the Electric Power Annual are researchers and analysts and, ultimately, individuals with policy- and decisionmaking responsibilities in electric utility companies. Financial and investment institutions, economic development organizations interested in new power plant construction, special interest groups, lobbyists, electric power associations, and the news media will find data in the Electric Power Annual useful. In the public sector, users include analysts, researchers, statisticians, and other professionals with regulatory, policy, and program responsibilities for Federal, State, and local governments. The Congress and other legislative bodies may also be interested in general trends related to electricity at State and national levels. Much of the data in these reports can be used in analytic studies to evaluate new legislation. Public service commissions and other special government groups share an interest in State-level statistics. These groups can also compare the statistics for their States with those of other jurisdictions

  19. Electric power emergency handbook

  1. Substituting oil by electric power

    International Nuclear Information System (INIS)

    Lichtenberg, H.

    1981-01-01

    Parting from the development of primary energy use the author refers to the latest investigations and results presented on the 1980 World Energy Conference and with special regard to oil points out the threatening exhaustion of fossil energy resources. Maintaining the economic structure of the Federal Republic of Germany implies an orientation away from oil. Due to its flexible application technology and quasi-inexhaustible energy resources electric power may substantially contribute to oil substitution which as a matter of fact is of particular interest in connection with the heat market. Coal alone cannot substitute both oil and nuclear energy. Thus, the above postulates the use of the latter. Leaving nuclear energy inactive today will effect an increase in the demand for oil the negative consequences of which would weight heavily upon the anyhow unbalanced import/export ratio of the Federal Republic of Germany.

  12. Nuclear power's effects on electric rate making

    International Nuclear Information System (INIS)

    Smith, D.S.; Lancaster, A.A.

    1978-01-01

    Government and the electric utility industry are re-evaluating nuclear power's contribution to the total U.S. energy supplies. This article addresses how the recently increased nuclear plant construction and operation costs are translated into the prices that consumers pay for electricity. The electric rates that consumers pay must reflect the costs of producing electricity, as well as the costs of transmission, distribution, metering, and billing. The use of nuclear power for electric production is anticipated to grow rapidly so as to meet a larger portion of our country's electricity needs through the end of the century; so nuclear power costs are expected to be an even larger portion of the total electricity price. There are certain rate-making issues that are actively being discussed in public forums and before state and Federal regulatory bodies. These issues are not unique to nuclear power, but take on added significance when nuclear power is used by utilities to produce electricity because of the technology required and because of the type, timing, and magnitude of the costs involved. These are: (1) inclusion of construction work in progress in the rate base; (2) fuel adjustment clauses and treatment of nuclear fuel cycle costs; (3) treatment of certain taxes under the rate-making method called normalization or deferral accounting (sometimes referred to as ''phantom taxes''); and (4) rate treatment for particular nuclear expense items reflecting costs of delays, plant cancellations, and operational slowdowns

    Electrical power system options for Mars Manned Modules and Mars Surface Bases were evaluated for both near-term and advanced performance potential. The power system options investigated for the Mission Modules include photovoltaics, solar thermal, nuclear reactor, and isotope power systems. Options discussed for Mars Bases include the above options with the addition of a brief discussion of open loop energy conversion of Mars resources, including utilization of wind, subsurface thermal gradients, and super oxides. Electrical power requirements for Mission Modules were estimated for three basic approaches: as a function of crew size; as a function of electric propulsion; and as a function of transmission of power from an orbiter to the surface of Mars via laser or radio frequency. Mars Base power requirements were assumed to be determined by production facilities that make resources available for follow-on missions leading to the establishment of a permanently manned Base. Requirements include the production of buffer gas and propellant production plants.

    The first Administration-wide Quadrennial Energy Review (QER), released in April 2015, found that the “interacting and overlapping” division of authority between “federal, regional and state institutions and regulatory structures” for the electricity sector could “impede development of the grid of the future [and] . . . the development of markets that efficiently integrate” new and emerging technologies.1 While “technology is indifferent to state-Federal boundaries and jurisdictions,” the QER explained, “technology users cannot be.”2 The report concluded that “[b]oth Federal and state governments need to play constructive and collaborative roles in the future to ensure that consumers and industry are able to maximize the value of new technologies.”3 The QER recommended that the Department of Energy (“DOE”) facilitate such collaboration by playing a “convening role” to bring together state and federal regulators and other stakeholders to consider these issues.4 This paper provides background and analysis on these jurisdictional issues and the impact they may have on adoption of emerging energy technologies and coordination of markets for those technologies, in support of future dialogs on these subjects. In particular, this paper reviews the structure of the Federal Power Act (“FPA”),5 and compares the division of authority between the federal and state governments adopted there with other federal energy and energy-related statutes.

  18. Electric power grid interconnection in Northeast Asia

    International Nuclear Information System (INIS)

    Yun, Won-Cheol; Zhang, Zhong Xiang

    2006-01-01

    In spite of regional closeness, energy cooperation in Northeast Asia has remained unexplored. However, this situation appears to be changing. The government of South Korea seems to be very enthusiastic for power grid interconnection between the Russian Far East and South Korea to overcome difficulties in finding new sites for building power facilities to meet its need for increased electricity supplies. This paper analyzes the feasibility of this electric power grid interconnection route. The issues addressed include electricity market structures; the prospects for electric power industry restructuring in the Russian Federation and South Korea; the political issues related to North Korea; the challenges for the governments involved and the obstacles anticipated in moving this project forward; project financing and the roles and concerns from multilateral and regional banks; and institutional framework for energy cooperation. While there are many technical issues that need to be resolved, we think that the great challenge lies in the financing of this commercial project. Thus, the governments of the Russian Federation and South Korea involved in the project need to foster the development of their internal capital markets and to create confidence with international investors. To this end, on energy side, this involves defining a clear energy policy implemented by independent regulators, speeding up the already started but delayed reform process of restructuring electric power industry and markets, and establishing a fair and transparent dispute resolution mechanism in order to reduce non-commercial risks to a minimum. The paper argues that establishing a framework for energy cooperation in this region will contribute positively towards that end, although views differ regarding its specific form. Finally, given that North Korea has a crucial transit role to play and faces a very unstable political situation, it is concluded that moving the project forward needs to be

  1. Concerning the debate on electric-powered-vehicle emissions

    International Nuclear Information System (INIS)

    Sporckmann, B.

    1994-01-01

    The fact that electric-powered vehicles do not emit pollutants locally is obvious and must be considered as the main motive for their use. The global air pollution situation can only be of secondary importance because within the foreseeable future emissions linked to the use of electric-powered vehicles will remain within the variation width of power generation emissions that is not to be influenced. All the same, it is indispensable to consider the global situation. The author compares electric-powered vehicles with conventional ones by referring to the power generation of all federal German states. (orig.) [de

    1989-02-01

    The Public Utilities Regulatory Policies Act (PURPA) of 1979 requires that electrical utilities interconnect with qualifying facilities and purchase electricity at a rate based upon their full avoided costs (i.e., costs of providing both capacity and energy). Qualifying facilities (QF) include solar or geothermal electric units, hydropower, municipal solid waste or biomass-fired power plants, and cogeneration projects that satisfy maximum size, fuel use, ownership, location, and/or efficiency criteria. In Washington State, neither standard power purchase prices based upon a proxy ''avoided plant'', standard contracts, or a standard offer process have been used. Instead, a variety of power purchase contracts have been negotiated by developers of qualifying facilities with investor-owned utilities, public utility districts, and municipally-owned and operated utilities. With a hydro-based system, benefits associated with resource acquisition are determined in large part by how compatible the resource is with a utility's existing generation mix. Power purchase rates are negotiated and vary according to firm energy production, guarantees, ability to schedule maintenance or downtime, rights of refusal, power plant purchase options, project start date and length of contract; front-loading or levelization provisions; and the ability of the project to provide ''demonstrated'' capacity. Legislation was also enacted which allows PURPA to work effectively. Initial laws established ownership rights and provided irrigation districts, PUDs, and municipalities with expanded enabling powers. Financial processes were streamlined and, in some cases, simplified. Finally, laws were passed which are designed to ensure that development proceeds in an environmentally acceptable manner. In retrospect, PURPA has worked well within Washington. In the state of Washington, 20 small-scale hydroelectric projects with a combined generating capacity of

    The Arizona Governor’s Office of Energy Policy, in partnership with Tucson Electric Power (TEP), Tendril, and Next Phase Energy (NPE), formed the TEP Power Partners pilot project to demonstrate how residential customers could access their energy usage data and third party applications using data obtained from an Automatic Meter Reading (AMR) network. The project applied for and was awarded a Smart Grid Data Access grant through the U.S. Department of Energy. The project participants’ goal for Phase I is to actively engage 1,700 residential customers to demonstrate sustained participation, reduction in energy usage (kWh) and cost ($), and measure related aspects of customer satisfaction. This Demonstration report presents a summary of the findings, effectiveness, and customer satisfaction with the 15-month TEP Power Partners pilot project. The objective of the program is to provide residential customers with energy consumption data from AMR metering and empower these participants to better manage their electricity use. The pilot recruitment goals included migrating 700 existing customers from the completed Power Partners Demand Response Load Control Project (DRLC), and enrolling 1,000 new participants. Upon conclusion of the project on November 19, 2013; 1,390 Home Area Networks (HANs) were registered; 797 new participants installed a HAN; Survey respondents’ are satisfied with the program and found value with a variety of specific program components; Survey respondents report feeling greater control over their energy usage and report taking energy savings actions in their homes after participating in the program; On average, 43 % of the participants returned to the web portal monthly and 15% returned weekly; and An impact evaluation was completed by Opinion Dynamics and found average participant savings for the treatment period1 to be 2.3% of their household use during this period.2 In total, the program saved 163 MWh in the treatment period of 2013.

  19. Nuclear power in the power economy of the Federal Republic of Germany in 1989

    International Nuclear Information System (INIS)

    Junk, H.

    1990-01-01

    In 1989, the gross electricity generation in nuclear power plants rose by 3.0% to 149.4 TWh. As in 1988, nuclear power with a 33.9% share made the highest contribution of all energy sources to the supply of electricity in the Federal Republic of Germany. In the public electricity supply sector, nuclear power plants in 1989 dominated with a 39.3% share in gross electricity generation. This performance was made possible, above all, by the commissioning of the Neckarwestheim-II plant. The period of utilization of the nuclear power plants dropped from 6549 h to 6245 h in 1989. The gross electricity consumption in the Federal Republic of Germany rose by 2.2% from 431.5 TWh to 441.1 TWh. This growth rate is identical with that of 1988. The net electricity consumption, however, increased by only 1.6%, i.e. 6.4 TWh. The difference in growth between the net and gross electricity consumption levels is due to an increased consumption of plant and pumping power, partly as a consequence of the wider use of desulfurization and denitrification plants. This again confirmed the trend, already apparent in 1988, of the growth of electricity consumption becoming independent of the grwoth of the gross national product. Only a slight change was recorded in the structure of the use of energy sources. While nuclear power achieved high growth rates of 9.1% in 1987 and 11.2% in 1988, the 1989 growth stayed at the moderate level of 3.0%. Nevertheless, nuclear power was able to raise its contribution to the consumption of primary energy from 12.0% to 12.6%. (orig.) [de

    International Nuclear Information System (INIS)

    Rudenko, Y.N.

    1993-01-01

    The generation of electric power in the USSR is based on the Unified Electric Power System (UEPS) whose network cover most of the habitable territory of the country. Therefore, the development of the UEPS governs the overall evolution of the electric power generation in the country. At present, eleven out of thirteen joint electric power systems, which supply electricity to most of the USSR, are operating within the UEPS. The total electric power generation in the country reached 1728 billion kWh in 1990, of which the UEPS supplied approximately 90%. About 70% of installed capacity of the UEPS is fossil-fuelled power plants, about 12 % is nuclear power plants, and about 18% is hydroelectric power plants. The system-forming grid of the UEPS is made up of transmission lines of 220, 330, 500 and 750 kV. The on-line supervisory control of the UEPS is achieved by four-level automated system of dispatch control (UEPS, joint electric power systems, regional electric power systems, electric power plants, substations,electric grid regions). The development and extension of the UEPS in the USSR ensure higher reliability and quality of electric power supply to end-users, combined with higher efficiency. The principal problem facing the UEPS are as follows: the need to ensure environmental protection and efficiency of the steam power plants; to improve the safety and efficiency of nuclear power plants. The solution to these problems will define the conditions of the UEPS development, as well as electric power systems of other countries, at least for the coming two decades. This paper characterizes the peculiarities of the UEPS development over the last 20 years, including the installed capacity structure and the system-forming electric power grid. Special attention is paid to the environmental problems related to functioning and development of the UEPS and to the means of their solution. (author)

    2005-01-01

    This Guide to Federal Regulation of Sales of Imported Electricity in Canada, Mexico, and the United States promotes cross-border electricity trade. It provides information on federal regulation of cross-border electricity trade and is intended to be used together with a companion guide called the North American Regulation of International Electricity Trade which outlines regulations for the construction and operation of cross-border power lines and the permitting requirements for electricity exports and imports between Canada, Mexico and the United States. The guide outlines the basic elements of the general federal regulatory process that applies to a given North American cross-border electricity trade. It offers an improved understanding of the applicable country's federal regulatory regime. Different federal government agencies within each country may regulate different aspects of a particular cross-border electricity trade. This guide does not examine the requirements that may apply at the state or provincial government levels. Rather, it is a collaborative effort of the 3 national energy departments and energy regulators that support the Experts Group on Electricity Regulatory Issues, a specialized unit assembled by the North American Energy Working Group (NAEWG). It was noted that the energy policies and regulations of each nation can change periodically

    Schmitt, D.; Duengen, H.; Wilhelm, M.

    1986-01-01

    In spite of the fact that analyses of the cost of electric power generation as the result of international comparative evaluations are indisputably relevant, problems pending in connection with the costs of representative power plant technologies are of the methodological bind. German authors have hitherto also been failing to clear up and consider all aspects connected with the problems of data acquisition and the adequate interpretation of results. The analysis presented by the paper abstracted therefore aims at the following: 1) Systematization of the different categories of cost relevant in connection with international comparative evaluation. Classification into different categories of decision making and development of standards meeting the requirements of international comparative evaluation. 2) Calculation of relevant average financial costs of Western German, America and French fossil-fuel and nuclear power plants by means of adequate calculation models, that is the assessment of costs with regard to countries and power plant technologies which are relevant to the Federal Republic of Germany. 3) Analysis of the resulting differences and determinantal interpretation.

    1989-01-01

    A thermally powered electrical generating system for use in a space vehicle is disclosed. The rate of storage in a thermal energy storage medium is controlled by varying the rate of generation and dissipation of electrical energy in a thermally powered electrical generating system which is powered from heat stored in the thermal energy storage medium without exceeding a maximum quantity of heat. A control system (10) varies the rate at which electrical energy is generated by the electrical generating system and the rate at which electrical energy is consumed by a variable parasitic electrical load to cause storage of an amount of thermal energy in the thermal energy storage system at the end of a period of insolation which is sufficient to satisfy the scheduled demand for electrical power to be generated during the next period of eclipse. The control system is based upon Kalman filter theory.

  2. Electric power's new competitive marketplace

    International Nuclear Information System (INIS)

    Hornick, R.; Zeppieri, J.; Rudden, K.

    1993-01-01

    Currently, competition is limited primarily to power generation, the sale of wholesale bulk power, and fuel substitution at the point of end use. However, within the next several years, the rivalry will focus on large, energy-intensive industrial and large commercial customers. Driven by the disparity in rates among neighboring and regional utilities, large users are expected to lobby aggressively for retail wheeling and access to new supplies. New competitors will provide customers with additional supply options, forcing traditional utilities to offer better prices and or service. Competition at the point of end use also will increase as the natural gas industry develops new end-use technologies, gas utilities compete more aggressively, and some state regulatory commissions promote fuel switching as part of integrated resource planning (IRP) and demand-side management (DSM). However, as long as electric utilities are subject to cost-based rate of return regulation within price-sensitive markets, they will be a competitive disadvantage. The paper discusses the following: competitive risks by market segment, wholesale markets, industrial markets, commercial markets, residential markets, and franchise markets

  3. Electrical power generation by mechanically modulating electrical double layers.

    Science.gov (United States)

    Moon, Jong Kyun; Jeong, Jaeki; Lee, Dongyun; Pak, Hyuk Kyu

    2013-01-01

    Since Michael Faraday and Joseph Henry made their great discovery of electromagnetic induction, there have been continuous developments in electrical power generation. Most people today get electricity from thermal, hydroelectric, or nuclear power generation systems, which use this electromagnetic induction phenomenon. Here we propose a new method for electrical power generation, without using electromagnetic induction, by mechanically modulating the electrical double layers at the interfacial areas of a water bridge between two conducting plates. We find that when the height of the water bridge is mechanically modulated, the electrical double layer capacitors formed on the two interfacial areas are continuously charged and discharged at different phases from each other, thus generating an AC electric current across the plates. We use a resistor-capacitor circuit model to explain the results of this experiment. This observation could be useful for constructing a micro-fluidic power generation system in the near future.

    2006-01-01

    Since it is not economically reasonable to build parallel electricity networks, in Finland, Sweden, Norway and Denmark, electricity distribution is protected by monopoly. However, electricity production and selling have been opened up to competition by connecting the transmission networks of these countries together, and it is possible to produce electricity where it is cheapest. A common electricity power market, called Nord Pool, has been created where electricity can be bought, sold or used as an exchange product. In order to help students understand the operation of electricity markets and the use of different electricity exchange products, the Department of Electrical Engineering at Lappeenranta University developed a scheme in which the theory can be used in practice. In the scheme, students are given the responsibility to manage the electricity markets of power companies in order analyze, plan and make decisions, which are skills required on the open power markets. The paper provided an introduction to the electricity markets in Nordic countries and discussed Nord Pool and its products. Information about education at the Department of Electrical Engineering at Lappeenranta University of Technology was also presented.

    The application of advanced electric power system technology to an all electric airplane results in an estimated reduction of the total takeoff gross weight of over 23,000 pounds for a large airplane. This will result in a 5 to 10 percent reduction in direct operating costs (DOC). Critical to this savings is the basic electrical power system component technology. These advanced electrical power components will provide a solid foundation for the materials, devices, circuits, and subsystems needed to satisfy the unique requirements of advanced all electric aircraft power systems. The program for the development of advanced electrical power component technology is described. The program is divided into five generic areas: semiconductor devices (transistors, thyristors, and diodes); conductors (materials and transmission lines); dielectrics; magnetic devices; and load management devices. Examples of progress in each of the five areas are discussed. Bipolar power transistors up to 1000 V at 100 A with a gain of 10 and a 0.5 microsec rise and fall time are presented. A class of semiconductor devices with a possibility of switching up to 100 kV is described. Solid state power controllers for load management at 120 to 1000 V and power levels to 25 kW were developed along with a 25 kW, 20 kHz transformer weighing only 3.2 kg.

  10. Import of electric power increased by 19 %

    International Nuclear Information System (INIS)

    Anon.

    2000-01-01

    The import of electric power increased by 19% in 1999. Due to the decrease in the electric power export the net import of electric power increased even more. Electric power import from Sweden was 6000 GWh, import from Russia 5200 GWh and import from Norway 100 GWh. The electric power export in 1999 was only 200 GWh. The generation of nuclear power increased 5% and the consumption of wood-based fuels by 3%. The increase in nuclear power generation is based on increment of the power output capacities of the power plants. The consumption of peat decreased by 12% and the production of hydroelectric power by 15%. The decrement of the peat consumption is based on the changes in energy taxation. The production of hydroelectric power decreased to the normal level after the rainy year 1998. Oil consumption remained nearly the same as in 1998 even though the national product increased in 1999 by 3.5%. The wind power generation was doubled in 1999. The share of it is still only about 0.01% of the total energy consumption. Carbon dioxide emissions from coal and peat, decreased by 1.0 million tons, down to 56 million tons. The present emissions are now only about 2 million tons higher than during the reference year 1990. The emissions have decreased by 5 million tons since 1996 when they were at their highest

This paper investigates the development of an options market for bulk power trading in a market setup while considering power system planning and operational constraints and/or requirements. In so doing it considers the different market based financial derivative instruments while can be used to trade electrical power in bulk and examines how established tools such as Optimal Power Flow (OPF) may be applied in helping to develop a price for bulk power transactions under a market based setup.

  10. An Optimum Solution for Electric Power Theft

    Directory of Open Access Journals (Sweden)

    Aamir Hussain Memon

    2013-07-01

    Full Text Available Electric power theft is a problem that continues to plague power sector across the whole country. Every year, the electricity companies face the line losses at an average 20-30% and according to power ministry estimation WAPDA companies lose more than Rs. 125 billion. Significantly, it is enough to destroy the entire power sector of country. According to sources 20% losses means the masses would have to pay extra 20% in terms of electricity tariffs. In other words, the innocent consumers pay the bills of those who steal electricity. For all that, no any permanent solution for this major issue has ever been proposed. We propose an applicable and optimum solution for this impassable problem. In our research, we propose an Electric power theft solution based on three stages; Transmission stage, Distribution stage, and User stage. Without synchronization among all, the complete solution can not be achieved. The proposed solution is simulated on NI (National Instruments Circuit Design Suite Multisim v.10.0. Our research work is an implicit and a workable approach towards the Electric power theft, as for conditions in Pakistan, which is bearing the brunt of power crises already

    Huttar, D.; Bronnev, G.; Fromm, N.

    1992-01-01

    This paper reports on the Burning Plasma Experiment (BPX) which when operating at a toroidal field of 8.1 tesla and a plasma current of 10.6 megamps, requires peak power of 1235 megawatts and total pulse energy of over 21 gigajoules. These requirements are twice and over four times the corresponding figures for the Tokamak Fusion Test Reactor (TFTR), respectively. The design of the BPX power system has evolved, along with the tokamak, over a period of several years and has included studies of several alternative approaches. The reapplication of the existing TFTR power and energy facilities has been basic to all approaches. Among the new sources of pulse power and energy that have been considered are: direct utility grid pulsing, new flywheel units, and lead-acid storage batteries. The toroidal field power requirements are the greatest of the BPX subsystems and, fortunately, are sufficiently free of dynamics to allow the consideration of all approaches. Additional design challenges were presented by the multiplicity of plasma control scenarios incorporated in the BPX physics planning and the power response demanded of the plasma position control system

    1977-01-01

    A basic conclusion established by the seven essays presented is that nowhere within the complex decision-making process of the electric power industry is there any provision for systematically considering the curtailment of consumption as a serious alternative to continued expansion of power production. Six recommendations are summarized for concrete steps toward remedying this deficiency as a result of examining the essays. Continued expansion of power generation could result in desirable consequences of economic growth, jobs, ready transportation, and many consumer conveniences; undesirable consequences are: increasing air and water pollution, further depletion of nonrenewable resources, and increased dependence on foreign sources of energy. The papers are: A Cybernetic Analysis of Certain Energy Consumption Patterns, by Kenneth Sayre; Social and Environmental Value in Power Plant Licensing: A Study in the Regulation of Nuclear Power by Vaughn McKim; Legal and Economic Aspects of the Electric Utility's ''Mandate to Serve'', by Charles Murdock; Economies of Scale in the Electric Power Industry, by Kenneth Jameson; Dynamics of Growth in the U.S. Electric Power Industry, by Ellen Maher; Utilitarianism and Cost-Benefit Analysis: An Essay on the Relevance of Moral Philosophy to Bureaucratic Theory, by Alasdair MacIntyre; and An Ethical Analysis of Power Company Decision-Making, by Kenneth Goodpaster and Kenneth Sayre.

    Three types of policies that are prominent in the federal debate over addressing greenhouse gas emissions in the United States are a cap-and-trade program (CTP) on emissions, a renewable portfolio standard (RPS) for electricity production, and tax credits for renewable electricity producers. Each of these policies would have different consequences, and combinations of these policies could induce interactions yielding a whole that is not the sum of its parts. This paper utilizes the Haiku electricity market model to evaluate the economic and technology outcomes, climate benefits, and cost-effectiveness of three such policies and all possible combinations of the policies. A central finding is that the carbon dioxide (CO{sub 2}) emissions reductions from CTP can be significantly greater than those from the other policies, even for similar levels of renewable electricity production, since of the three policies, CTP is the only one that distinguishes electricity generated by coal and natural gas. It follows that CTP is the most cost-effective among these approaches at reducing CO{sub 2} emissions. An alternative compliance payment mechanism in an RPS program could substantially affect renewables penetration, and the electricity price effects of the policies hinge partly on the regulatory structure of electricity markets, which varies across the country. - Research Highlights: > Climate benefits of cap-and-trade are greater than of tax credits or RPS. > Cap-and-trade is more cost-effective at reducing emissions than tax credits or RPS. > Tax credits are a subsidy to production that raises electricity consumption. > Alternative compliance payment can substantially affect the outcome of RPS.

  1. RISKS OF LOSING CONTROLLABILITY WHILE LIBERALIZING THE ELECTRIC POWER INDUSTRY

    Directory of Open Access Journals (Sweden)

    Yu. S. Petrusha

    2015-01-01

    Full Text Available The paper analyses controllability qua a reliability characteristic of the electric-power grid controlling system. The following notions are used: the object (environment susceptibility towards the control stimuli, the controlling system adequacy, environment of the secure functioning. The author points to the necessity of accounting for the limitations of technological and organizational character. While liberalizing the electric-power industry, the backbone control-principle “the industry functioning reliability” is being replaced with the principle of “profit-making” that requires complete restatement of the control philosophy.The conflict between commercial benefit gaining and the reliability assurance expenses leads to losing controllability in all the managerial links and to probable catastrophic consequences. The recapitulation of the Russian Federation power industry privatization substantiates concerns of the liberal ideas poor survivability in the ex-Soviet territories. The results of degradation of the secure-functioning environment demonstrate affinity of the mechanisms that triggered the Chernobyl NPP, Fukusima NPP, and Sayan-Shushenskya HPP disasters. Securing reliability of the strategic objects leaves the competence boundaries of the electricpower industry.The topical issue of Belorussian electric-power industry functioning and developing is the combination of technical re-equipment (developing the operational dispatch management and the control-system organizational modernizing in general with gradual and controllable transition to the market mechanisms of functioning. Herewith, preserving the state monopoly on regime provision for the operation of the electric-power system should not leave out the industry appeal for outside investment and is regulated by the optimal degree and intensity of the state participation in governing the electric-power supply industry.

    The purpose of the investigation is to compare the economics of various electrical power generation options for the City of Galena. Options were assessed over a 30-year project period, beginning in 2010, and the final results were compared on the basis of residential customer electric rates ($/kWh). Galena's electric utility currently generates power using internal combustion diesel engines and generator sets. Nearby, there is an exposed coal seam, which might provide fuel for a power plant. Contributions to the energy mix might come from solar, municipal solid waste, or wood. The City has also been approached by Toshiba, Inc., as a demonstration site for a small (Model 4S) nuclear reactor power plant. The Yukon River is possibly a site for in-river turbines for hydroelectric power. This report summarizes the comparative economics of various energy supply options. This report covers: (1) thermal and electric load profiles for Galena; (2) technologies and resources available to meet or exceed those loads; (3) uses for any extra power produced by these options; (4) environmental and permitting issues and then; and (5) the overall economics of each of the primary energy options.

    In this paper, we examine the effects of federal tax laws on the financial attractiveness of seven renewable and four conventional electric power generating technologies adopted by investor owned utilities (IOUs) and non-utility electricity generators (NUGs). The results show that federal income tax laws applicable to renewable generating technologies generally provide very attractive financial incentives for the adoption of these technologies by IOUs and NUGs. If an IOU and NUG is subject to the alternative minimum tax, however, it may not be able to take full advantage of these financial incentives. (author)

    Full Text Available Finding new energy sources is an important challenge of our times. A lot of research focuses on identifying such sources that can also be exploited with relatively simple and efficient systems. These sources can be either new materials that can be used to generate energy, or solutions to scavenge already existing forms of energy. Part of the latter class of solutions, the system presented in this paper converts the energy consumed by many people in gyms (or even at home, during exercise into electric energy. This energy exists anyway, because people want to be healthier or to look better. Currently, this significant (in our opinion amount of energy is actually wasted and transformed into heat. Instead, in this study, a prototype scavenging system (dedicated to fitness/stationary bikes to collect and (reuse this energy is presented. Specifically, we depict the design of a low-budget system that uses existing, discrete components and is able to scavenge some of the energy spent by the biker. The experimental results show that the system is functional, but its efficiency is limited by (mechanical losses before the collection.

  7. Hedging electricity price volatility using nuclear power

    Mari, Carlo

    2014-01-01

    Highlights: • Nuclear power is an important asset to reduce the volatility of electricity prices. • Unpredictability of fossil fuels and carbon prices makes power prices very volatile. • The dynamics of fossil fuels and carbon prices is described by Brownian motions. • LCOE values, volatilities and correlations are obtained via Monte Carlo simulations. • Optimal portfolios of generating technologies are get using a mean–variance approach. - Abstract: The analysis presented in this paper aims to put in some evidence the role of nuclear power as hedging asset against the volatility of electricity prices. The unpredictability of natural gas and coal market prices as well as the uncertainty in environmental policies may affect power generating costs, thus enhancing volatility in electricity market prices. The nuclear option, allowing to generate electricity without carbon emissions, offers the possibility to reduce the volatility of electricity prices through optimal diversification of power generating technologies. This paper provides a methodological scheme to plan well diversified “portfolios” of generating capacity that minimize the electricity price risk induced by random movements of fossil fuels market prices and by unpredictable fluctuations of carbon credits prices. The analysis is developed within a stochastic environment in which the dynamics of fuel prices as well as the dynamics of carbon credits prices is assumed to evolve in time according to well defined Brownian processes. Starting from market data and using Monte Carlo techniques to simulate generating cost values, the hedging argument is developed by selecting optimal portfolio of power generating technologies using a mean–variance approach

  8. A methodology for Electric Power Load Forecasting

    2011-06-01

    Full Text Available Electricity demand forecasting is a central and integral process for planning periodical operations and facility expansion in the electricity sector. Demand pattern is almost very complex due to the deregulation of energy markets. Therefore, finding an appropriate forecasting model for a specific electricity network is not an easy task. Although many forecasting methods were developed, none can be generalized for all demand patterns. Therefore, this paper presents a pragmatic methodology that can be used as a guide to construct Electric Power Load Forecasting models. This methodology is mainly based on decomposition and segmentation of the load time series. Several statistical analyses are involved to study the load features and forecasting precision such as moving average and probability plots of load noise. Real daily load data from Kuwaiti electric network are used as a case study. Some results are reported to guide forecasting future needs of this network.

    2000-07-01

    Barsebaeck 1 was closed on 30 November 1999. Barsebaeck's output of approximately 4 TWh per year will primarily be replaced by imports from coal-fired plants in Denmark and Germany. During the year, the closure of Swedish fossil-fired condensing power stations continued. With that, over 3,000 MW of peak-load power has been shut down during recent years. Consequently, situations entailing shortages of power can arise. On the deregulated electricity market, it is only the system operators that have a satisfactory overview of the overall electricity balance. The Swedish Power Association has thus lobbied the government as regards the need to elucidate Svenska Kraftnaet's responsibility. In a governmental decision from December, Svenska Kraftnaet was given the task of, among other things, monitoring the available capacity during peak loads and developing market instruments that can contribute to safeguarding the availability of power during peak loads. Svenska Kraftnaet has acquired gas turbines with a combined output power of 400 MW from Vattenfall. In order to cover the remaining requirement for rapid disruption reserves, Svenska Kraftnaet also has agreements with several power producers regarding a further 800 MW of gas turbine capacity. One further possibility lies in agreements with industry regarding the disconnection of consumption during times of peak loading. On 1 January 2000, the nuclear power tax was increased by SEK 0.005 per kWh to SEK 0.027 per kWh. This means that the nuclear power companies pay approximately SEK 1,800 MSEK per year in fiscal taxation on their nuclear power generation. The tax on electrical energy, paid by the consumer, was raised by SEK 0.011 to SEK 0.162 per kWh. The tax on diesel fuel was increased at the same time by SEK 0.25 per litre. In addition, a special network fee of SEK 0.002 per kWh came into existence in order to finance small-scale electricity generation, following removal of the obligation-to-receive system. The Swedish

    This paper is about electricity market operation when looking from the wind power producers' point of view. The focus in on market time horizons: how many hours there is between the closing and delivering the bids. The case is for the Nordic countries, the Nordpool electricity market and the Danish wind power production. Real data from year 2001 was used to study the benefits of a more flexible market to wind power producer. As a result of reduced regulating market costs from better hourly predictions to the market, wind power producer would gain up to 8% more if the time between market bids and delivery was shortened from the day ahead Elspot market (hourly bids by noon for 12-36 h ahead). An after sales market where surplus or deficit production could be traded 2 h before delivery could benefit the producer almost as much, gaining 7%

    Attention is drawn to business opportunities in Iran, a middle-eastern country that is still in the process of rebuilding its power generating capacity in the wake of its eight-year-long war with Iraq. In reviewing opportunities to tap into this market , the article lists a number of factors that must be considered before rushing to follow the current. One of these factors is the U.S. trade embargo against Iran. Under this embargo Canada does not allow the re-export of goods of U.S. origin from Canada to Iran. The complex character of doing business in Iran by foreign companies must also be considered. Nevertheless,, those who are well prepared to face the restrictions and are willing to take the time to learn about the 'Iranian way' may receive considerable help from the Export Development Corporation, including financing and insurance on a case-by-case basis. The Canadian government's program for export market development also offers direct financial assistance to Canadian exporters in an effort to reduce the risk of entering a foreign market. The Canadian Embassy in Tehran can also provide useful advice and assistance. There is also http://exportsource.gc.ca., Team Canada Inc.'s on-line resource that may be consulted for export information

    The purpose of this book is to present the picture of more than 110-year old history of the building and maintenance of power stations in Slovakia. The beginnings were the same as elsewhere in the world. Small, local sources of electrical energy had been built for own needs and it had lasted for decades, until people realized that electricity could be produced for the whole communities and towns and that there was a possibility of the supply of the electricity for public. The purposeful electrification although started in this country only after the World War I, after the Law No. 438/1918 had been issued. While the period till the World War I has the character of endless experiments of utilizing electrical industry, transport, agriculture and households, the period after World War I is explicitly focused on building of unified electrification system for production, transport and distribution of electrical energy. Instead of course, the experts are trained for the first time at professional technical schools and after the year 1943 also at the School of Technology in Bratislava, the predecessor of the University of technology and at the other professional schools. Time is ready. The demand for electrical energy is growing together with the power of generators and voltage level of distribution lines. Besides the energy supply, also power plants, production and supply of heat started to be prosperous, especially in the regions where conditions for such activities had been provided. The changes in the 'power station family' are also registered in the legislative documents, which better present and explain the new historical circumstances. The lives of power station employees were deeply affected by many political and war event in the period of the World War II. In spite of this fact, they could manage their tasks also in these extraordinary conditions. The short part is about the social security of employees. The conclusion contains also basic conceptions envisaged for

    The Southeastern Federal Power Program (SEFPP) consists of all activities associated with the production, transmission and disposition of Federal power marketed under Section 5 of the Flood Control Act of 1944 from projects in the ten southeastern states. The ten states are: Virginia, West Virginia, North Carolina, South Carolina, Georgia, Florida, Alabama, Mississippi, Tennessee, and Kentucky. Power is marketed to customers in 11 states - the above ten plus Illinois. SEFPP includes the accounts of two separate Federal government agencies- the Southeastern Power Administration (Southeastern) of the Department of Energy and the U.S. Army Corps of Engineers (Corps). Southeastern purchases, transmits, and markets power within four separate power systems (each including one or more Corps generating projects for which rates are set). Specific and joint-use costs allocated to power are included in the attached statements of assets. Federal investment and liabilities under utility plant and cash. The accounts of SEFPP are maintained in conformity with generally accepted accounting principles and the Uniform System of Accounts prescribed for electric utilities by the Federal Energy Regulatory Commission (FERC). SEFPP`s accounting policies also reflect requirements of specific legislation and executive directives issued by the applicable government agencies. Southeastern and Corps properties and income are exempt from taxation. Southeastern and the Corps receive Congressional appropriations through the Department of Energy (DOE) and the Department of Defense to finance their operations. The Corps also receives Congressional appropriations to finance construction of its hydroelectric projects.

  19. Power generation investment in electricity markets

    International Nuclear Information System (INIS)

    2003-01-01

    Most IEA countries are liberalizing their electricity markets, shifting the responsibility for financing new investment in power generation to private investors. No longer able to automatically pass on costs to consumers, and with future prices of electricity uncertain, investors face a much riskier environment for investment in electricity infrastructure. This report looks at how investors have responded to the need to internalize investment risk in power generation. While capital and total costs remain the parameters shaping investment choices, the value of technologies which can be installed quickly and operated flexibly is increasingly appreciated. Investors are also managing risk by greater use of contracting, by acquiring retail businesses, and through mergers with natural gas suppliers. While liberalization was supposed to limit government intervention in the electricity market, volatile electricity prices have put pressure on governments to intervene and limit such prices. This study looks at several cases of volatile prices in IEA countries' electricity markets, and finds that while market prices can be a sufficient incentive for new investment in peak capacity, government intervention into the market to limit prices may undermine such investment

    Pakistan is facing a severe electricity crisis due to a persistent and widening gap between demand and available system generating capacity. The worsening of power shortages has become a major political issue, reflecting the hardships for individuals and businesses. It threatens to undermine the credibility and legitimacy of government and to further stress the social fabric of the country. The power crisis did not emerge suddenly. It is the direct result of imprudent and reckless energy policies over the last three decades. These policies have impeded the development of cheap and abundant domestic energy sources. They have also resulted in very inefficient fuel-mix choices, compromising energy and economic security. Pakistan's energy bankruptcy is ultimately due to massive institutional and governance failure. This paper analyzes the problems confronting Pakistan's electricity sector and identifies the key elements of a potential policy response to address the country's severe power crisis. - Highlights: ► We analyze the structure, conduct, and performance of Pakistan's electricity sector. ► The causes and economic impacts of Pakistan's electricity shortages are analyzed. ► We identify the potential policy response to the power crisis

In order to cover the remaining requirement for rapid disruption reserves, Svenska Kraftnaet also has agreements with several power producers regarding a further 800 MW of gas turbine capacity. One further possibility lies in agreements with industry regarding the disconnection of consumption during times of peak loading. On 1 January 2000, the nuclear power tax was increased by SEK 0.005 per kWh to SEK 0.027 per kWh. This means that the nuclear power companies pay approximately SEK 1,800 MSEK per year in fiscal taxation on their nuclear power generation. The tax on electrical energy, paid by the consumer, was raised by SEK 0.011 to SEK 0.162 per kWh. The tax on diesel fuel was increased at the same time by SEK 0.25 per litre. In addition, a special network fee of SEK 0.002 per kWh came into existence in order to finance small-scale electricity generation, following removal of the obligation-to-receive system

    Under the direction of the Nuclear Regulatory Commission, Sandia National Laboratories has been conducting confirmatory research in fire protection for nuclear power plants. As a part of this research, a program was developed to determine the damageability of electrical-cable insulation to thermal radiation in a loaded cable tray. The critical flux or threshold level at which cable damage occurs in the form of electrical failure (short from conductor to tray) and nonpiloted ignition was determined for two types of electrical cable, one an IEEE-383 qualified cable and the other an unqualified cable. A program was also developed to determine the damageability of electrical-cable insulation to constant temperature, thermal exposure

    Market power in liberalised electricity markets dominated by hydropower is analyzed in four chapters. The existing literature on competition in hydropower markets is briefly presented and examined. Chapter 1 discusses the effects of market power in the context of acquisitions in a situation where transmission capacity is constrained. Chapter 2 and 3 elaborate on the issue of competition and market power when water inflow is uncertain, and finally Chapter 4 focuses on the supply function equilibrium model in the context of a hydropower market

  8. Buying Renewable Electric Power in Montgomery County, Maryland

    Cember, Richard P.

    2008-08-01

    From mid-August 2007 until mid-August 2008, my home electricity supply was 100% wind-generated. My experience in switching to wind-generated electric power may be of interest to fellow AGU members for three reasons. First, Montgomery County, Md., where I live, is one of the few jurisdictions in the United States that has both an electric power tax and a renewable energy credit. The county is therefore a case study in price-based public policy for greenhouse gas emissions control. Second, I was surprised by the comparatively small price difference (or ``price premium'') between wind-generated and conventionally generated power in the county, and I believe that Eos readers will be similarly surprised. Third, because so many U.S. federal agencies concerned with Earth science are based in the Washington, D. C., area, a high concentration of AGU members live in Montgomery County and may be personally interested in evaluating the price of reducing carbon dioxide emissions from the generation of their own residential electricity.

    Barsebaeck 1 was closed on 30 November 1999. Barsebaeck's output of approximately 4 TWh per year will primarily be replaced by imports from coal-fired plants in Denmark and Germany. During the year, the closure of Swedish fossil-fired condensing power stations continued. With that, over 3,000 MW of peak-load power has been shut down during recent years. Consequently, situations entailing shortages of power can arise. On the deregulated electricity market, it is only the system operators that have a satisfactory overview of the overall electricity balance. The Swedish Power Association has thus lobbied the government as regards the need to elucidate Svenska Kraftnaet's responsibility. In a governmental decision from December, Svenska Kraftnaet was given the task of, among other things, monitoring the available capacity during peak loads and developing market instruments that can contribute to safeguarding the availability of power during peak loads. Svenska Kraftnaet has acquired gas turbines with a combined output power of 400 MW from Vattenfall.

    As renewable generation has become less expensive during recent decades, and it becomes more accepted by the global population, the focus on renewable generation has expanded to include new types with promising future applications, such as river and tidal generation. Although the utilization of power electronics and electric machines in industry is phenomenal, the emphasis on system design is different for various sectors of industry. In precision control, robotics, and weaponry, the design emphasis is on accuracy and reliability with less concern for the cost of the final product. In energy generation, the cost of energy is the prime concern; thus, capital expenditures (CAPEX) and operations and maintenance expenditures (OPEX) are the major design objectives. This paper describes the electrical power conversion aspects of river and tidal generation. Although modern power converter control is available to control the generation side, the design was chosen on the bases of minimizing the CAPEX and OPEX; thus, the architecture is simple and modular for ease of replacement and maintenance. The power conversion is simplified by considering a simple diode bridge and a DC-DC power converter to take advantage of abundant and low-cost photovoltaic inverters that have well-proven grid integration characteristics (i.e., the capability to produce energy with good power quality and control real power and voltage on the grid side).

    In 2010, the NEA in conjunction with the International Energy Agency produced an analysis of the Projected Costs of Electricity for almost 200 power plants, covering nuclear, fossil fuel and renewable electricity generation. That analysis used lifetime costs to consider the merits of each technology. However, the lifetime cost analysis is less applicable in liberalised markets and does not look specifically at the viewpoint of the private investor. A follow-up NEA assessment of the competitiveness of nuclear energy against coal- and gas-fired generation under carbon pricing has considered just this question. The economic competition in electricity markets is today between nuclear energy and gas-fired power generation, with coal-fired power generation not being competitive as soon as even modest carbon pricing is introduced. Whether nuclear energy or natural gas comes out ahead in their competition depends on a number of assumptions, which, while all entirely reasonable, yield very different outcomes. The analysis in this study has been developed on the basis of daily data from European power markets over the last five-year period. Three different methodologies, a Profit Analysis looking at historic returns over the past five years, an Investment Analysis projecting the conditions of the past five years over the lifetime of plants and a Carbon Tax Analysis (differentiating the Investment Analysis for different carbon prices) look at the issue of competitiveness from different angles. They show that the competitiveness of nuclear energy depends on a number of variables which in different configurations determine whether electricity produced from nuclear power or from CCGTs generates higher profits for its investors. These are overnight costs, financing costs, gas prices, carbon prices, profit margins (or mark-ups), the amount of coal with carbon capture and electricity prices.

    Pivirotto, D. S.

    1976-01-01

    The requirements of the electric utility industry as the primary potential market for geothermal energy are analyzed, based on a series of structured interviews with utility companies and financial institution executives. The interviews were designed to determine what information and technologies would be required before utilities would make investment decisions in favor of geothermal energy, the time frame in which the information and technologies would have to be available, and the influence of the governmental politics. The paper describes the geothermal resources, electric utility industry, its structure, the forces influencing utility companies, and their relationship to geothermal energy. A strategy for federal stimulation of utility investment in geothermal energy is suggested. Possibilities are discussed for stimulating utility investment through financial incentives, amelioration of institutional barriers, and technological improvements.

    The industry systems in Brazil are responsible for a consumption of over 50% (fifty per cent) of the total electrical power generated: therefore, they are import loads in power flow studies, and their modeling should be as much the best. Usually, in power flow studies, the industry systems are modeled by taking the influence of the power (active and reactive) and of the current on the voltage into account. Since the inducting motors, within the industry systems, represent at least 50% (fifty per cent) of the power consumption, and a large part of them is oversize, it is proposed to represent the industry systems as a function of the characteristic of power on shaft versus voltage into account. Since the induction motors, within the industry systems, represent at least 50% (fifty per cent) of the power consumption, and a large part of them is oversized, it is proposed to represent the industry systems as a function of the characteristics of power on shaft versus voltage for the analysis of power systems, aiming a load flow study. Thereafter, a model of an equivalent motor which has a basis the typical performance curve of an induction motor is present. This model is obtained from empirical parameters, surveyed from a population of over 1000 motors. (author) 3 refs., 1 fig., 4 tabs.

    The generation of electric power is one important source of pollutants such as mercury, sulfur dioxide, nitrogen oxides, and fine particulate matter that can affect the respiratory, cardiovascular, and central nervous systems and cause pregnancy complications. But protecting people from environmental health hazards has become increasingly complex. Air pollutants are often invisible and travel many miles virtually undetected. Nurses can play a critical role in preventive strategies, as well as in the national debate on energy production and dependence on fossil fuels.

    The FEA in April of 1974 established an Interagency Task Group on Power Plant Reliability, which was charged with the broad objective of improving the productivity of existing and planned large fossil-fueled and nuclear power plants. It took approximately 11 months for the task force to publish a report, ''Report on Improving the Productivity of Electrical Power Plants'' (FEA-263-G), a detailed analysis and comparison of successful and below-average-performance power plants. The Nuclear Service Corp. portion of this study examined four large central-station power plants: two fossil (coal) and two nuclear plants. Only plants with electrical generation capacities greater than 400 MWe were considered. The study included the following: staff technical skill, engineering support, QA program, plant/corporate coordination, operation philosophy, maintenance programs, federal/state regulations, network control, and equipment problems. Personnel were interviewed, and checklists providing input from some 21 or more plant and corporate personnel of each utility were utilized. Reports and other documentation were also reviewed. It was recognized early that productivity is closely allied to technical skills and positive motivation. For this reason, considerable attention was given to people in this study

    The results of a series of telephone interviews with groups of users of information on solar thermal electric power are described. These results, part of a larger study on many different solar technologies, identify types of information each group needed and the best ways to get information to each group. The report is 1 of 10 discussing study results. The overall study provides baseline data about information needs in the solar community. An earlier study identified the information user groups in the solar community and the priority (to accelerate solar energy commercialization) of getting information to each group. In the current study only high-priority groups were examined. Results from five solar thermal electric power groups of respondents are analyzed: DOE-Funded Researchers, Non-DOE-Funded Researchers, Representatives of Utilities, Electric Power Engineers, and Educators. The data will be used as input to the determination of information products and services the Solar Energy Research Institute, the Solar Energy Information Data Bank Network, and the entire information outreach community should be preparing and disseminating.

    2015-12-01

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

    A dual capacity permanent split capacitor electric motor system is provided with a stator having main and auxiliary windings. The main stator winding includes two winding sections which are connected in parallel with each other and across a pair of line terminals while the auxiliary winding is connected in series with a capacitor to form a circuit branch which is connected between the line terminals for operation at a first output power level. Switching means are provided to reconnect the main stator winding sections in series with each other and in series with a second capacitor to form a circuit branch which is connected between the line terminals while the stator auxiliary winding is connected directly between the line terminals for operation at a second output power level. Automatic rotation reversal occurs when the motor switches from the first to the second output power level.

  17. New directions in electric power financing

    International Nuclear Information System (INIS)

    Jechoutek, K.G.; Lamech, Ranjit

    1995-01-01

    This paper argues that it is necessary to raise the eyes from the current focus on independent power projects, buttressed by guarantees, to the longer horizon of electric power financing in open markets. Transitional strategies will need to move beyond the commonly seen IPP activity that occurs without fundamental sector reform, and demand-side incentives that introduce further market distortions. These efforts will have to focus on macroeconomic stabilization, removal of price distortions, as well as sector and corporate reform. Mobilization of domestic capital will be essential for sustainable sector financing. Although guarantees to encourage power sector investment can be designed to selectively cover risks, their elimination through fundamental sector reform should be the ultimate goal. Over the longer-term traditional corporate finance should become a more common financing strategy than project finance. Innovations in performance risk management and consumer credit will be crucial to the financing of energy efficiency. (author)

    The analysis and optimization needs for planning and operation of the electric power system are challenging due to the scale and the form of model representations. The connected network spans the continent and the mathematical models are inherently nonlinear. Traditionally, computational limits have necessitated the use of very simplified models for grid analysis, and this has resulted in either less secure operation, or less efficient operation, or both. The research conducted in this project advances techniques for power system optimization problems that will enhance reliable and efficient operation. The results of this work appear in numerous publications and address different application problems include optimal power flow (OPF), unit commitment, demand response, reliability margins, planning, transmission expansion, as well as general tools and algorithms.

    Current trends indicate that worldwide electricity distribution networks are experiencing a transformation towards direct-current (DC) at both generation and consumption level. This tendency is powered by the outburst of various electronic loads and, at the same time, with the struggle to meet...... of systems generally provide improved reliability in comparison to their alternating current (AC) counterparts since the number of active elements in DC-DC power electronic devices is smaller than in DC-AC converters. Besides that, control design in DC systems is significantly simpler since...... the high set goals for share of renewable energy sources (RESs) in satisfying total demand. RESs operate either natively at DC or have a DC link in the heart of their power electronic interface, whereas the end point connection of electronic loads, batteries and fuel cells is exclusively DC. Therefore...

    Automatic Detection of Electric Power Troubles (A DEPT) is an expert system that integrates knowledge from three different suppliers to offer an advanced fault-detection system. It is designed for two modes of operation: real time fault isolation and simulated modeling. Real time fault isolation of components is accomplished on a power system breadboard through the Fault Isolation Expert System (FIES II) interface with a rule system developed in-house. Faults are quickly detected and displayed and the rules and chain of reasoning optionally provided on a laser printer. This system consists of a simulated space station power module using direct-current power supplies for solar arrays on three power buses. For tests of the system's ablilty to locate faults inserted via switches, loads are configured by an INTEL microcomputer and the Symbolics artificial intelligence development system. As these loads are resistive in nature, Ohm's Law is used as the basis for rules by which faults are located. The three-bus system can correct faults automatically where there is a surplus of power available on any of the three buses. Techniques developed and used can be applied readily to other control systems requiring rapid intelligent decisions. Simulated modeling, used for theoretical studies, is implemented using a modified version of Kennedy Space Center's KATE (Knowledge-Based Automatic Test Equipment), FIES II windowing, and an ADEPT knowledge base.

    Low Power Factor of electrical loads cause high current is drawn from power supply. The impact of this circumstance is influenced by impedance of electrical load. Therefore, the key consideration of this study is how impedance of electrical loads influence power factor of electrical loads, and then power distribution as the whole. This study is important to evaluate the right action to mitigate low power factor effectively for electrical energy efficiency purpose. (author)

  6. Thermophotovoltaic Arrays for Electrical Power Generation

    Energy Technology Data Exchange (ETDEWEB)

    Sarnoff Corporation

    2003-11-18

    Sarnoff has designed an integrated array of thermophotovoltaic (TPV) cells based on the In(Al)GaAsSb/GaSb materials system. These arrays will be used in a system to generate electrical power from a radioisotope heat source that radiates at temperatures from 700 to 1000 C. Two arrays sandwich the slab heat source and will be connected in series to build voltage. Between the arrays and the heat source is a spectral control filter that transmits above-bandgap radiation and reflects below-bandgap radiation. The goal is to generate 5 mW of electrical power at 3 V from a 700 C radiant source. Sarnoff is a leader in antimonide-based TPV cell development. InGaAsSb cells with a bandgap of 0.53 eV have operated at system conversion efficiencies greater than 17%. The system included a front-surface filter, and a 905 C radiation source. The cells were grown via organo-metallic vapor-phase epitaxy. Sarnoff will bring this experience to bear on the proposed project. The authors first describe array and cell architecture. They then present calculated results showing that about 80 mW of power can be obtained from a 700 C radiator. Using a conservative array design, a 5-V output is possible.

  7. PROVIDING QUALITY OF ELECTRIC POWER IN ELECTRIC POWER SYSTEM IN PARALLEL OPERATION WITH WIND TURBINE

    Directory of Open Access Journals (Sweden)

    Yu. A. Rolik

    2016-01-01

    Full Text Available The problem of providing electric power quality in the electric power systems (EPS that are equipped with sufficiently long air or cable transmission lines is under consideration. This problem proved to be of particular relevance to the EPS in which a source of electrical energy is the generator of wind turbines since the wind itself is an instable primary energy source. Determination of the degree of automation of voltage regulation in the EPS is reduced to the choice of methods and means of regulation of power quality parameters. The concept of a voltage loss and the causes of the latter are explained by the simplest power system that is presented by a single-line diagram. It is suggested to regulate voltage by means of changing parameters of the network with the use of the method of reducing loss of line voltage by reducing its reactance. The latter is achieved by longitudinal capacitive compensation of the inductive reactance of the line. The effect is illustrated by vector diagrams of currents and voltages in the equivalent circuits of transmission lines with and without the use of longitudinal capacitive compensation. The analysis of adduced formulas demonstrated that the use of this method of regulation is useful only in the systems of power supply with a relatively low power factor (cosφ < 0.7 to 0.9. This power factor is typical for the situation of inclusion the wind turbine with asynchronous generator in the network since the speed of wind is instable. The voltage regulation fulfilled with the aid of the proposed method will make it possible to provide the required quality of the consumers’ busbars voltage in this situation. In is turn, it will make possible to create the necessary conditions for the economical transmission of electric power with the lowest outlay of reactive power and the lowest outlay of active power losses.

  8. Development of the Mexican electric power sector

    International Nuclear Information System (INIS)

    Escofet, A.

    1981-06-01

    In 1980 Mexico had a population of 68 million, mostly concentrated in a few cities with many other areas being practically unpopulated. The country is semi-industrialized, and in order to achieve better standards of living, economic growth will have to continue at about 7.5 percent or more, particularly if the population continues to increase at 2.9 percent per year. The total installed electrical capacity at the end of 1980 was 14 600 MW; the per capita consumption of electricity was 910 KWh. The present government has as a goal an 8 percent annual growth rate in gross domestic product until 1995, resulting in forecast of a 12.5 percent growth rate in the electric sector to about 410 TWh per year. Hydroelectric power could be used to produce 80 TWh a year by 2000 if capacity were quadrupled. The use of coal for the production of electricity is beginning, and it is planned to generate 40 TWh a year from this source by 2000. Geothermal power should yield 20 TWh by then. A goal has been set of 20 000 MW of installed nuclear capacity by the end of the century; this would produce about 130 TWh, leaving some 280 TWh to be generated by oil or gas. The planned nuclear program must include the development of a strong Mexican nuclear industry, so that in 20 years 80 percent of the nuclear plant components could be locally produced. Ultimately it is hoped that Mexico will have the capability of installing, with its own resources, five or six large nuclear plants per year

  12. Federal tax incentives affecting coal and nuclear power economics

    International Nuclear Information System (INIS)

    Chapman, D.

    1982-01-01

    This paper analyzes the effect of federal corporate income tax incentives on coal and nuclear power developments. It estimates (1) the magnitudes of tax incentives in relationship to utility costs, (2) the relative magnitude of benefits going to coal and nuclear facilities, and (3) the influence which the time paths of tax payments and after-tax net income have upon possible incentives for premature construction and excess capacity. Utility planners currently believe that nuclear power enjoys an after-tax competitive advantage over coal plants. Investigation of investment-related credits, deductions, and exclusions in the Internal Revenue Code shows that nuclear power enjoys a more favorable tax subsidy because of its greater capital intensity. In the absence of tax subsidies, no utility would prefer nuclear power to coal generation. Tax changes now under consideration could increase the tax benefits to both without disturbing the differential advantage held by nuclear power. 43 references, 2 figures, 4 tables

    The aim of the appraisal of a project is to examine the economic need which a project is designed to meet, to judge whether the project is likely to meet this need in an efficient way, and to conclude what conditions should be attached to eventual Bank financing. Bank involvement continues throughout the life of the project helping to ensure that each project is carried out at the least possible cost and that it makes the expected contribution to the country's development. This paper gives an idea about the origin, nature and functions of the World Bank Group, describes the criteria used by the Bank in its power project appraisals, discusses the Bank's views on nuclear power, and concludes with a review of past lending and probable future sources of financing of electrical expansion in the less developed countries.

    2010-09-01

    Full Text Available The Satellite Launch Vehicle electrical network, which is currently being developed in Brazil, is sub-divided for analysis in the following parts: Service Electrical Network, Controlling Electrical Network, Safety Electrical Network and Telemetry Electrical Network. During the pre-launching and launching phases, these electrical networks are associated electrically and mechanically to the structure of the vehicle. In order to succeed in the integration of these electrical networks it is necessary to employ techniques of electrical power distribution, which are proper to Launch Vehicle systems. This work presents the most important techniques to be considered in the characterization of the electrical power supply applied to Launch Vehicle systems. Such techniques are primarily designed to allow the electrical networks, when submitted to the single-phase fault to ground, to be able of keeping the power supply to the loads.

    A Centurion electric power system was simulated. Data from a section of the Tshwane Municipality network in South Africa were used to evaluate the use of a power system stabilizer (PSS) and a flexible AC transmission system (FACTS) controller and a thyristor controlled series compensator (TCSC). The single-machine infinite bus (SMIB) power system model was used to validate the effectiveness of the systems under various disturbance scenarios. The system's synchronous generator was characterized as a higher order model. Thevenin's equivalent of the transmission network was used to reduce the single-machine infinite bus power system in relation to the reactance of the transformer, transmission line per circuit, and the impedance of the receiving end system. Three-phase faults were applied at the generator terminal busbar in order to evaluate the model's performance. The study demonstrated that use of the PSS and TCSC-based controllers provide an improved response in terms of both overshoot and settling time. 17 refs., 10 figs.

  7. The impact of wind power on electricity prices

    Brancucci Martinez-Anido, Carlo; Brinkman, Greg; Hodge, Bri-Mathias

    2016-08-01

    This paper investigates the impact of wind power on electricity prices using a production cost model of the Independent System Operator - New England power system. Different scenarios in terms of wind penetration, wind forecasts, and wind curtailment are modeled in order to analyze the impact of wind power on electricity prices for different wind penetration levels and for different levels of wind power visibility and controllability. The analysis concludes that electricity price volatility increases even as electricity prices decrease with increasing wind penetration levels. The impact of wind power on price volatility is larger in the shorter term (5-min compared to hour-to-hour). The results presented show that over-forecasting wind power increases electricity prices while under-forecasting wind power reduces them. The modeling results also show that controlling wind power by allowing curtailment increases electricity prices, and for higher wind penetrations it also reduces their volatility.

  10. Nuclear reactors for space electric power

    International Nuclear Information System (INIS)

    Buden, D.

    1978-06-01

    The Los Alamos Scientific Laboratory is studying reactor power plants for space applications in the late 1980s and 1990s. The study is concentrating on high-temperature, compact, fast reactors that can be coupled with various radiation shielding systems and thermoelectric, dynamic, or thermionic electric power conversion systems, depending on the mission. Lifetimes of 7 to 10 yr at full power, at converter operating temperatures of 1275 to 1675 0 K, are being studied. The systems are being designed such that no single-failure modes exist that will cause a complete loss of power. In fact, to meet the long lifetimes, highly redundant design features are being emphasized. Questions have been raised about safety since the COSMOS 954 incident. ''Fail-safe'' means to prevent exposure of the population to radioactive material, meeting the environmental guidelines established by the U.S. Government have been and continue to be a necessary requirement for any space reactor program. The major safety feature to prevent prelaunch and launch radioactive material hazards is not operating the reactor before achieving the prescribed orbit. Design features in the reactor ensure that accidental criticality cannot occur. High orbits (above 400 to 500 nautical miles) have sufficient lifetimes to allow radioactive elements to decay to safe levels. The major proposed applications for satellites with reactors in Earth orbit are in geosynchronous orbit (19,400 nautical miles). In missions at geosynchronous orbit, where orbital lifetimes are practically indefinite, the safety considerations are negligible. Orbits below 400 to 500 nautical miles are the ones where a safety issue is involved in case of satellite malfunction. The potential missions, the question of why reactors are being considered as a prime power candidate, reactor features, and safety considerations will be discussed

  11. Nuclear reactor power for an electrically powered orbital transfer vehicle

    Jaffe, L.; Beatty, R.; Bhandari, P.

    1987-01-01

    To help determine the systems requirements for a 300-kWe space nuclear reactor power system, a mission and spacecraft have been examined which utilize electric propulsion and this nuclear reactor power for multiple transfers of cargo between low Earth orbit (LEO) and geosynchronous Earth orbit (GEO). A propulsion system employing ion thrusters and xenon propellant was selected. Propellant and thrusters are replaced after each sortie to GEO. The mass of the Orbital Transfer Vehicle (OTV), empty and dry, is 11,000 kg; nominal propellant load is 5000 kg. The OTV operates between a circular orbit at 925 km altitude, 28.5 deg inclination, and GEO. Cargo is brought to the OTV by Shuttle and an Orbital Maneuvering Vehicle (OMV); the OTV then takes it to GEO. The OTV can also bring cargo back from GEO, for transfer by OMV to the Shuttle. OTV propellant is resupplied and the ion thrusters are replaced by the OMV before each trip to GEO. At the end of mission life, the OTV's electric propulsion is used to place it in a heliocentric orbit so that the reactor will not return to Earth. The nominal cargo capability to GEO is 6000 kg with a transit time of 120 days; 1350 kg can be transferred in 90 days, and 14,300 kg in 240 days. These capabilities can be considerably increased by using separate Shuttle launches to bring up propellant and cargo, or by changing to mercury propellant

    Exposures to electric and magnetic fields are among the most ubiquitous exposures that the Canadian population experiences. Sources of electric and magnetic field exposures may be occupational or residential and include proximity to certain types of electrical equipment, transmission and distribution power lines as well as appliance use. The early studies of children tended toward a consistent association between risks for leukemia and brain cancer and residential proximity to power lines having high wire configuration. More recent studies-and studies which have attempted to improve upon the measurement of exposure by using calculated fields, point-in-time or personal monitoring-have been inconsistent, with some suggesting increased risk and others not. Occupational exposures have suggested an increase in risk for leukemia, and to a lesser extent brain cancer and Non-Hodgkin lymphoma. However, studies of residential exposures and cancer in adults generally have suggested no effect. Laboratory work has been unable to demonstrate a biological mechanism which might explain the epidemiological findings. In spite of extensive efforts over the past 20 years and many expert reviews, it has been difficult to reach consensus regarding the carcinogenic effects of electric and magnetic fields. Exposure assessment has proven to be complex, and agreement on the relevant exposure metric has not yet been obtained. There is justification to question whether point-in-time measures in homes are appropriate indices of the relevant etiological exposure, as they fail to account for changes over time, peak exposures or time-varying fields. Nevertheless, it is probably desirable to err on the side of caution in not placing too much weight on the inconsistencies. The IARC has classified EMF as a "possible carcinogen" which refers to the circumstances where there is limited evidence of carcinogenicity in humans and inadequate evidence in experimental animals. The IARC review indicated

    Nuclear and radioisotope powered electric thrusters are being developed as primary in-space propulsion systems for potential future robotic and piloted space missions. Possible applications for high power nuclear electric propulsion include orbit raising and maneuvering of large space platforms, lunar and Mars cargo transport, asteroid rendezvous and sample return, and robotic and piloted planetary missions, while lower power radioisotope electric propulsion could significantly enhance or enable some future robotic deep space science missions. This paper provides an overview of recent U.S. high power electric thruster research programs, describing the operating principles, challenges, and status of each technology. Mission analysis is presented that compares the benefits and performance of each thruster type for high priority NASA missions. The status of space nuclear power systems for high power electric propulsion is presented. The paper concludes with a discussion of power and thruster development strategies for future radioisotope electric propulsion systems,

  15. Electric power industry restructuring and ROE: The case of Korea Electric Power Corporation

    International Nuclear Information System (INIS)

    Won, Gu-Hwan

    2007-01-01

    Korea's electric power industry was previously run by Korea Electric Power Corporation (KEPCO) in a natural monopoly-type structure. As economy of scale was waning in influence and management effectiveness began to increase in importance, KEPCO was divided into six subsidiaries and faced competition beginning in April 2001. This study evaluates the restructuring process for Korea's power industry and analyzes the financial outcomes based on return on equity (ROE). The results show that the ROE ratio increased. In the analysis period (1993-2004), the financial ratio showed a better performance than that before restructuring. However, productivity ratios such as productivity of capital (or gross value added to total assets) and gross value added to property, plant, and equipment decreased compared to the situation before restructuring. It is believed that the results were due to the increased financial leverage of KEPCO. For this reason, KEPCO should make further efforts to manage its debt in a systematic way

  18. Informatics requirements for a restructured competitive electric power industry

    Energy Technology Data Exchange (ETDEWEB)

    1996-08-01

    The electric power industry in the United States is undergoing a slow but nonetheless dramatic transformation. It is a transformation driven by technology, economics, and politics; one that will move the industry from its traditional mode of centralized system operations and regulated rates guaranteeing long-run cost recovery, to decentralized investment and operational decisionmaking and to customer access to true spot market prices. This transformation will revolutionize the technical, procedural, and informational requirements of the industry. A major milestone in this process occurred on December 20, 1995, when the California Public Utilities Commission (CPUC) approved its long-awaited electric utility industry restructuring decision. The decision directed the three major California investor-owned utilities to reorganize themselves by the beginning of 1998 into a supply pool, at the same time selling up to a half of their thermal generating plants. Generation will be bid into this pool and will be dispatched by an independent system operator. The dispatch could potentially involve bidders not only from California but from throughout western North America and include every conceivable generating technology and scale of operation. At the same time, large customers and aggregated customer groups will be able to contract independently for their supply and the utilities will be required to offer a real-time pricing tariff based on the pool price to all their customers, including residential. In related proceedings concerning competitive wholesale power markets, the Federal Energy Regulatory Commission (FERC) has recognized that real-time information flows between buyers and sellers are essential to efficient equitable market operation. The purpose of this meeting was to hold discussions on the information technologies that will be needed in the new, deregulated electric power industry.

    It was developed a model for the calculation of costs of electric generation of nuclear plants. The developed pattern was validated with the one used by the United States Council for Energy Awareness (USCEA) and the Electric Power Research Institute (EPRI), in studies of comparison of alternatives for electric generation of nuclear plants and fossil plants with base of gas and of coal in the United States described in the guides calls Technical Assessment Guides of EPRI. They are mentioned in qualitative form some changes in the technology of nucleo electric generation that could be included in the annual publication of Costs and Parameters of Reference for the Formulation of Projects of Investment in the Electric Sector of the Federal Commission of Electricity. These changes are in relation to the advances in the technology, in the licensing, in the construction and in the operation of the reactors called advanced as the A BWR built recently in Japan.

  1. Radiation exposure control of nuclear power plant personnel in the Federal Republic of Germany

    International Nuclear Information System (INIS)

    Mehl, J.

    1980-01-01

    The analysis of exposure records of all persons engaged in radiation work at nuclear power plants of the Federal Republic of Germany has shown that annual collective doses increase rapidly with time. The annual gross electrical energy generated from nuclear power also increases rapidly with time, corresponding to about 11% of the total gross electrical energy produced in 1977/78. Therefore, it is obvious that there is an increase of both the risk and the benefit from nuclear power production. Whether in the course of time the situation develops more towards the risk or the benefit side is learned from the history of the annual ratio of the collective dose per gross electrical energy generated. This ratio shows a significant decrease since 1972. The decrease is due to the experience gained from operation of the first-generation plants, which led to several administrative measures aimed at an improved control of the collective doses of power plant personnel in the Federal Republic of Germany. The administrative measures include, among others, the introduction of the following requirements: (a) Everyone who applies for a nuclear power plant construction licence has to provide evidence that, in the design of the plant, full use is made of the experience gained from plants in operation with respect to reduction of collective doses of the power plant personnel. (b) Everyone who engages his employees on radiation work within operations for which an operation licence is required, but which is held by others, requires a special 'contractor licence'. (c) Every person engaged in radiation work on the basis of a contractor licence must carry a special exposure record book which is registered by the competent national authority. (author)

  9. Reserve valuation in electric power systems

    Science.gov (United States)

    Ruiz, Pablo Ariel

    Operational reliability is provided in part by scheduling capacity in excess of the load forecast. This reserve capacity balances the uncertain power demand with the supply in real time and provides for equipment outages. Traditionally, reserve scheduling has been ensured by enforcing reserve requirements in the operations planning. An alternate approach is to employ a stochastic formulation, which allows the explicit modeling of the sources of uncertainty. This thesis compares stochastic and reserve methods and evaluates the benefits of a combined approach for the efficient management of uncertainty in the unit commitment problem. Numerical studies show that the unit commitment solutions obtained for the combined approach are robust and superior with respect to the traditional approach. These robust solutions are especially valuable in areas with a high proportion of wind power, as their built-in flexibility allows the dispatch of practically all the available wind power while minimizing the costs of operation. The scheduled reserve has an economic value since it reduces the outage costs. In several electricity markets, reserve demand functions have been implemented to take into account the value of reserve in the market clearing process. These often take the form of a step-down function at the reserve requirement level, and as such they may not appropriately represent the reserve value. The value of reserve is impacted by the reliability, dynamic and stochastic characteristics of system components, the system operation policies, and the economic aspects such as the risk preferences of the demand. In this thesis, these aspects are taken into account to approximate the reserve value and construct reserve demand functions. Illustrative examples show that the demand functions constructed have similarities with those implemented in some markets.

    Large-scale, wide-range electric power uses in every-day life and industrial production processes took their start about a century ago. Until recently, high consumption growth rates developing even without specific marketing manipulations have shown the social value of electric power. While the historical use, namely the satisfaction of autonomous social needs, seems to belong to the past meanwhile, new electric power perspectives have been created by the requirements of pollution abatement and supply security which again challenge the satisfaction of autonomous social needs. Any anti-electric power policy would therefore be equivalent to an antisocial policy.

    1988-01-01

    As to the electric power facility plan in fiscal year 1988, 15 designated electric power enterprises made the notification to the Minister of International Trade and Industry in March, 1988. This outline of the facility plan summarized the plans of 66 enterprises in total, including the plans of municipally operated, joint thermal power and other enterprises in addition to the above 15. In order to ensure the stable supply of electric power, the Ministry of International Trade and Industry considers that it is indispensable to purposefully develop electric power sources and the facilities for distribution along this facility plan. The forecast for fiscal year 1997 is : total electric power demand 778.2 billion kWh, maximum power demand 151.21 million kW, and yearly load factor 56.9 %. This is equivalent to the yearly growth of 2.4 %. In fiscal year 1988, it is planned to present 29 plants of 2760 MW to the Power Source Development Coordination Council. The breakdown is : hydroelectricity 140 MW, thermal power 2010 MW, and nuclear power 610 MW. The Ministry guides electric power enterprises so as to realize the diversification of electric power sources. Also the increase of transmission and transformation facilities, the plan of equipment investment and others are reported. (Kako, I.)

    The liberalization of Japanese electricity market expanded to customers of over 50 kV on April 1, 2005 and more than 60% of the market has been already open. The discussion about the assistance measures of nuclear power generation in Japanese liberalization of electricity market has come to grow warmer gradually. The opinions on the competitiveness of nuclear power are inconsistency among the supporters of nuclear power. Some says that nuclear power is the most competitive, others says nuclear power require some sort of financial or political assistance in the deregulation of electricity market. In this study, based on financial statements of each Japanese electric power company, the constitution of generation cost of nuclear power is illustrated and various financial and economic characteristics, including ''merit of scale'' and the impact of new nuclear power plant construction on the finance of electric power company, are discussed. In addition, the economic features of nuclear power generation are compared with those of thermal power generation through the analysis of financial statements. Finally, support policies for nuclear power required in deregulation of electric utilities are examined in terms of fairness of competition and security of electricity supply

    This work has as purpose to diffuse in a general way the technology of the one modulate reactor of pebble bed. Because our country is in developing ways, the electric power demand goes in increase with that which it is presented the great challenge of satisfying this necessity, not only being in charge of the one fact per se, but also involving the environmental aspect and of security. Both factors are covered by the PBMR technology, which we approach in their basic aspects with the purpose that the public opinion knows it and was familiarized with this type of reactors that well could represent a solution for our growing electricity demand. We will treat this reactor visualizing it like part of a generation plant defining in first place to the itself reactor. We will see because that the system PBMR consists of 2 main sections: the reactor and the unit of energy conversion, highlighting that the principle of the PBMR reactor operation is based on the thermodynamic Brayton cycle cooled by helium and that, in turn, it transmits the energy in form of heat toward a gas turbine. In what concerns to the fuel, it peculiar design due to its spherical geometry is described, aspect that make to this reactor different from the traditional ones that use fuel rods. In fact in the fuel spheres of the PBMR it is where it resides great part of it inherent security since each particle of fuel, consistent in uranium dioxide, is lined one with coal and silicon carbide those which form an impenetrable barrier containing to the fuel and those radioactive products that result of the nuclear reactions. Such particles are encapsulated in graphite to form the sphere or 'pebble', of here born the name of this innovative technology. (Author)

    An analysis is performed to show that a utility solar-passive strategy can be used rather effectively in aiding the utility to obtain more efficient load factors and lower costs. The objectives are to determine the impact of active and passive solar energy designs for space conditioning and hot water heating for the residential sector upon the diurnal and annual load curves for several utilities, to assess the effect of present utility pricing policies, and to examine alternative pricing schemes, as well as Federal and state tax credits, as they may affect the optimal sizing and configuration of active solar and passive solar building components. The methodology, the systems model, an overall building design, building cost determination, and a description of TRNSYS are presented. The major parameters discussed that distinguish variation in the cost-effectiveness of particular building design fall into 5 categories: the weather, building configurations, building costs, utility costs and rates, and financial parameters (inclusive of tax credits for solar and energy conservation investment). Five utilities are studied: Colorado Springs Department of Public Utilities; Public Service Co. of New Mexico; New England Electric System; Pacific Gas and Electric; and Georgia Power Co.

    2001-01-01

    In spite of the mild weather in the year 2000 the electric power consumption in Finland increased by nearly 2%. The electric power consumption would be twice as high if the temperatures would have been the same as usually. Hydroelectric power generation in Norway, Sweden and Finland in 2000 was about 40 TWh higher than in 1999. The retained import of electric power in the year 2000 reached a new record, being 11.9 TWh, corresponding to 15% of the annual power consumption in Finland. The GNP in Finland increased in 2000 by 5.7%, and the estimate for 2001 is 4.5%. Total power consumption in Finland in 2000 was 79.1 TWh, which is 1.7% higher than in 1999. About 60% of the increase were covered by import of electric power and 40 % by increasing own power generation. The share of CHP production was 31% of the total power consumption, the share of nuclear power being 27%, the share of hydroelectric power 18% and that of coal and other common condensing power about 8%. The share of retained electric power import was 15%. The Finnish hydroelectric power plants generated 14.4 TWh electric power, which is nearly 15% more than in 1999. Due to the increased production of hydroelectric power and power import the production of coal and other condensing power decreased nearly 9%. The wind power generation increased rapidly being, however, only about 0.1% of the electric power consumption. Industrial power consumption was about 55% of the total, the share of households and agriculture being nearly 24%, and those of services and public sector over 17%. Power transmission and delivery losses were less than 4%. The electric power consumption of households decreased by nearly 2% due to the worm end of the year. The share of other consumers increased by nearly 3%. About 13 000 households acquired electric heating, so the number of electrically heated houses in Finland is 593 000 households. The industrial electric power consumption increased in 2000 by 2.7% up to 43.2 TWh. The share of

    2010-10-15

    The German federal government established the environmental goal of reducing carbon emissions from 1,033 million t in 1990 by 40% to 620 million t/a by 2020. The Federal Environmental Office reports a reduction by 26% for the past economic crisis year of 2009 over the reference year. Consequently, further efforts are needed along these lines if the objective is to be reached in 2020. Towards this end, the German government and industry founded the National Electric Mobility Platform on May 3, 2010 in an effort to make Germany a lead market for electric mobility and have one million electric vehicles operate on German roads by 2020. Federal Chancellor Angela Merkel in addition demands mobility in future to be ''more independent of resources, less pollutant to the environment, and more sustainable.'' These target criteria basically are met in the power supply sector when nuclear power is used to generate electricity. Against this backdrop, perspectives of electric mobility are outlined in terms of their environmental characteristics, and various approaches to achieving adequate electricity supply are explained. In view of the boundary conditions in power technology and power economy, the agreement reached by the present coalition government on September 6, 2010 about extending the plant life of the 17 German nuclear power plants supports the objective referred to above. This compromise of coalition politics exercises a bridge function in providing for an average plant life extension of 12 years over the current plant life limitations. The federal government considers this plant life extension a key feature of its new overall energy concept, which is to be more independent of resources, less polluting to the environment, and more sustainable than the current status quo.

    This report for the Swiss Federal Office of Energy (SFOE) summarises the work done in 2003 in the various research areas covered by the Swiss Electricity Research programme. Work done in the programme's five main areas - electricity transport and storage, high-temperature superconductivity, energy and information technologies, drives and electric motors, and appliances is reviewed. In the electricity transport and storage area an agreement with the Swiss Association of Electricity Producers (VSE) on the transfer of findings was made and the focus of work was set on decentralised systems. Also, the use of compressed-air storage systems was looked at and the AC corrosion of pipelines was examined. Swiss participation in an IEA Implementing Agreement for a Co-operative Programme for Assessing the Impact of High-Temperature Superconductivity on the Electric Power Sector is mentioned, as is the market potential of superconductive current limiters. A total of 8 institutions and industries are involved in theoretical or practical research in the area of high-temperature superconductors. Information and communications technologies are reviewed, including work on energy-efficient EDP server management. Work in other areas summarised includes lighting and uninterruptible power-supplies and work on the energy consumption of process control units. In the electrical drives area, work is summarised in various areas ranging from an industry agreement on the energy-efficiency of motors through to the optimisation of compressed-air systems and energy-efficient gearless drives. Efficient hotel minibars, the energy-efficiency potential in the area of water dispensers and the energy-efficiency potential of hot beverage dispensers used in the area of staff catering and the standby consumption of household appliances are just a few of the topics dealt with. Co-operation with Swiss institutions and international organisations such as the IEA is reviewed. Implementation work in the

  9. ANALYSIS OF GROSS REGIONAL PRODUCT FLUCTUATIONS AND ELECTRIC POWER CONSUMPTION IN 2005- 2014. RESERVES FOR DECREASING ELECTRIC POWER PRICES

    Suslov N. I.

    2016-09-01

    Full Text Available In this work we considered the trajectories of change in indicators characterizing the status of economics and power industry: gross regional product, electric power consumption, industrial production, energy prices and costs of delivering electric power to consumers in Russian regions for the last 10 years. Low global commodity prices and sanctions led to a sharp decrease of equipment import, which resulted in an acute problem of import substitution. The level of tariffs of natural monopolies is of great importance for industrial development. The goal of this work was to analyze possibilities for reducing electric power prices by changing the institutional and economic conditions of management. We analyzed not only the official information from Rosstat, but also government regulations, figures given in the official government publication «The Rossiyskaya Gazeta» as well as articles and interviews on economic problems of the electric power industry over the recent years published in «The Kommersant» newspaper. High tariffs of network marketing companies for electric energy transmission, state regulation of heating prices, financing the construction of new capacities by charging the payment in power provision contracts, high price of electric power of nuclear power plants lead to an annual increase in electric power prices for end users. In this work we considered possible solutions to limit the growth of electric power prices.

    1975-04-01

    Electric power demands in Japan have shown a remarkable growth at an annual rate of 12% since 1965. Nine electric power companies have invested large amounts of money so far, amounting to over 1 trillion yen every year since 1972. A survey of the electric power supply system and an estimation of the electric power demands in 1980 and in 1985 are given. It is expected that the main portion of electric power in the future will gradually be generated by nuclear plants. Financial features of the electrical power utilities, the credit risk of the electric power utilities, and the raising of funds by electric power utilities are discussed. It is concluded that it will be necessary (1) to expand the capital market, (2) to enable the electric power companies to issue a sufficient amount of bonds, (3) to make the Government financing institutions, such as the Japan Development Bank, provide the electric power companies with larger funds on a long-term and low-interest rate basis, and (4) even to take such drastic steps as subsidizing interest on private loans to the electric power companies.

    This paper considers diversity of generation and demand profiles against the different future energy scenarios and evaluates these on a technical basis. Compared to previous studies, this research applied a forecasting concept based on possible growth rates from publically electrical distribution scenarios concerning the UK. These scenarios were created by different bodies considering aspects such as environment, policy, regulation, economic and technical. In line with these scenarios, forecasting is on a long term timescale (up to every ten years from 2020 until 2050) in order to create a possible output of generation mix and demand profiles to be used as an appropriate boundary condition for the network simulation. The network considered is a segment of rural LV populated with a mixture of different housing types. The profiles for the 'future' energy and demand have been successfully modelled by applying a forecasting method. The network results under these profiles shows for the cases studied that even though the value of the power produced from each Micro-generation is often in line with the demand requirements of an individual dwelling there will be no problems arising from high penetration of Micro-generation and demand side management for each dwellings considered. The results obtained highlight the technical issues/changes for energy delivery and management to rural customers under the future energy scenarios

  14. Growth of electric power in Japan

    Papamarcos, J.

    1983-01-01

    No longer is it ''boom time'' or ''full speed ahead'' for the nuclear industry or other suppliers to the Japanese electric power companies, but Japan continues to move ahead with an aggressive program, and is taking the lead in the planning and design of advanced nuclear reactors and of advanced supercritical pressure fossil-fired units. With all the charges and countercharges being hurled back and forth about Japan's dominating influence in a significant part of world trade, it should be clear that the economy of that nation (and therefore its energy needs) is highly dependent on exports. The economic revitalization of that country, which started in the early 1950s, was based to a large extent on developing and integrating energy-intensive industries. During the 1960s, the average annual rate of growth of GNP exceeded 11%, and the average annual rate of growth in energy consumption exceeded 12%. During this period, great reliance was placed on low-cost imported oil to supply rapidly increasing energy needs

  18. Radiant smiles everywhere - before the Chernobyl accident. The situation of the electric utilities in the Federal Republic of Germany

    Energy Technology Data Exchange (ETDEWEB)

    1986-08-01

    The business reports presented by the Federal German electric utilities for 1985 are almost all simply brillant. Electricity consumption has been going up, some of the utilities even can boast about rates kept constant over the year. But before the printed business reports could be presented to the meetings of shareholders, a nasty cloud threw a dark shadow over all the brilliant results. The Chernobyl accident made some of the hymns over the nuclear electricity increases and nuclear power in general sound rather queer. Could we do without this energy source. Substituting nuclear power would yearly require: 28 million t of oil, or 41 million t of hard coal, or 142 million t of browncoal, or 38 thousand million cubic metres of natural gas. Extrapolating current conditions and assuming best achievements, renewable energy sources might be able to meet 6 p.c. of the primary energy demands by the year 2000.

    1989-01-01

    In designing a multiple load electrical system, the designer may wish to compare the performance of two setups: a common electrical source powering all loads, or separate electrical sources powering individual loads. Three types of electrical sources: an ideal voltage source, an ideal current source, and solar cell source powering resistive loads were analyzed for their performances in separate and common source systems. A mathematical proof is given, for each case, indicating the merit of the separate or common source system. The main conclusions are: (1) identical resistive loads powered by ideal voltage sources perform the same in both system setups, (2) nonidentical resistive loads powered by ideal voltage sources perform the same in both system setups, (3) nonidentical resistive loads powered by ideal current sources have higher performance in separate source systems, and (4) nonidentical resistive loads powered by solar cells have higher performance in a common source system for a wide range of load resistances.

  6. EVALUATING DEGREE OF ACTIVE POWER LOSSES REDUCTION IN THE ELECTRIC POWER LINES WITH REACTIVE POWER COMPENSATION

    Directory of Open Access Journals (Sweden)

    V. N. Radkevich

    2016-01-01

    Full Text Available The paper considers evaluation procedure for the degree of active power losses reduction in the power transmission lines under 1 kV and 6–10 kV of the systems of electric power supply of industrial enterprises with compensating installations mounted at the side of the customer. The capacitor installations conform to the applied voltage level and factor in dielectric losses in the capacitors. The voltage at the compensating device terminal changes from 0.95 to 1.05 of the capacitors nominal voltage. The study did not account for reactive power losses in the line, nor did it for its charge capacity, conditioned by relative shortness of the cable lines generally operating in the mains of industrial enterprises. For this reason, the quantities of reactive power being consumed and generated by the transmission line are negligible and do not significantly affect the reactive power flux. The researchers obtain functional relations that allow estimating the degree of power loss reduction in the transmission line factoring in its explicit initial data. They perform mathematical analysis of the obtained functional relations and study the function by means of derivatives. The function extremum points are found as well as the intervals of its increment and decrement. A graphical research of the obtained functional relation is performed. It is ascertained that reduction of the active power losses is contingent on the line and the capacitor-installation engineering factors, the electrical energy consumer reactive load value as well as the voltage applied to the capacitor installation. The functional relations presented in the article can be employed in scoping calculation necessary for decision making on the reactive power compensation in systems of the industrial facilities electric power supply. Their account will allow a more accurate estimate of technical and economic effect of the capacitor bank installation in the electrical mains under 1 kV and 6

    An alternating current power generation system adopted to inject power in an already powered power line is discussed. The power generating system solves to adjustably coup an induction motor, as a generator, to an ac power line wherein the motor and power line are connected through a triac. The triac is regulated to normally turn on at a relatively late point in each half cycle of its operation, whereby at less than operating speed, and thus when the induction motor functions as a motor rather than as a generator, power consumption from the line is substantially reduced. The principal application will be for windmill powered generation.

  19. Scenarios for low carbon and low water electric power plant ...

    Science.gov (United States)

    In the water-energy nexus, water use for the electric power sector is critical. Currently, the operational phase of electric power production dominates the electric sector's life cycle withdrawal and consumption of fresh water resources. Water use associated with the fuel cycle and power plant equipment manufacturing phase is substantially lower on a life cycle basis. An outstanding question is: how do regional shifts to lower carbon electric power mixes affect the relative contribution of the upstream life cycle water use? To test this, we examine a range of scenarios comparing a baseline with scenarios of carbon reduction and water use constraints using the MARKet ALlocation (MARKAL) energy systems model with ORD's 2014 U.S. 9-region database (EPAUS9r). The results suggest that moving toward a low carbon and low water electric power mix may increase the non-operational water use. In particular, power plant manufacturing water use for concentrating solar power, and fuel cycle water use for biomass feedstock, could see sharp increases under scenarios of high deployment of these low carbon options. Our analysis addresses the following questions. First, how does moving to a lower carbon electricity generation mix affect the overall regional electric power water use from a life cycle perspective? Second, how does constraining the operational water use for power plants affect the mix, if at all? Third, how does the life cycle water use differ among regions under

    Measurements were conducted to investigate electric and magnetic fields (EMFs) from 120 Hz to 10 kHz and 1.2 to 100 kHz in 9 electric or hybrid vehicles and 4 gasoline vehicles, all while being driven. The range of fields in the electric vehicles enclosed the range observed in the gasoline vehicles. Mean magnetic fields ranged from nominally 0.6 to 3.5 µT for electric/hybrids depending on the measurement band compared with nominally 0.4 to 0.6 µT for gasoline vehicles. Mean values of electric fields ranged from nominally 2 to 3 V m -1 for electric/hybrid vehicles depending on the band, compared with 0.9 to 3 V m -1 for gasoline vehicles. In all cases, the fields were well within published exposure limits for the general population. The measurements were performed with Narda model EHP-50C/EHP-50D EMF analysers that revealed the presence of spurious signals in the EHP-50C unit, which were resolved with the EHP-50D model. © The Author 2016.

  3. The State of Restructuring the Electric Power Industry in the United States

    Science.gov (United States)

    Davis, Ricardo A.

    Through federal legislation, the electric power industry in the United States is encouraged to unbundle the ownership structure into separate entities for generation, transmission, and distribution of electric power. The electric power industry represents more than 7% of the U.S. gross domestic product and some of the country's major economic sectors, such as mining and chemical processing. The purpose of this qualitative, phenomenological study is to explore the phenomenon of the U.S. electric power industry restructuring from the viewpoint of those who have been at the forefront of the effort. The conceptual framework for this study is based in the Public Utilities Regulatory Policy Act (PURPA), which guided the restructuring of the U.S. electric power industry. The focus of the research questions was determining the informed perceptions and lived experience of participants. A purposive sampling approach was utilized along with a semi structured, open-ended interview with 20 participants who brought context-specific knowledge of the phenomenon. A sequential inductive process of coding, categorizing, and abstracting was performed. The findings indicate that the professionals within the industry continue to struggle with what is perceived as a restructuring effort that has come to a standstill, and doubts continue regarding the benefits or disadvantages of restructuring. The study contributes to social change by informing challenges to restructuring within the electric power industry, changes that include the potential for significant impacts to customers and especially for low income residents if subsidies are removed in a restructured environment.

    The moderate increase of electrical energy demands (3% at present) can only be met by the parallel application of fossil and nuclear power plants and by electric power import via the transmission lines of the CMEA countries. The changes in the electrical energy and fuel demands and the development of the available capacities during the last 35 years are reviewed. The major purpose of Hungarian power economy is to save hydrocarbon fuels by taking advantages of power import opportunities by operating nuclear power plants at maximum capacity and the coal fired power stations at high capacity. The basic principles, the algorithm applied to optimize the load distribution of the electrical power system are discussed in detail with special attention to the role of nuclear power. The planned availability of nuclear power plants and the amount of electricity generated by nuclear plants should also be optimized. (V.N.)

  7. Operating health analysis of electric power systems

    Science.gov (United States)

    Fotuhi-Firuzabad, Mahmud

    The required level of operating reserve to be maintained by an electric power system can be determined using both deterministic and probabilistic techniques. Despite the obvious disadvantages of deterministic approaches there is still considerable reluctance to apply probabilistic techniques due to the difficulty of interpreting a single numerical risk index and the lack of sufficient information provided by a single index. A practical way to overcome difficulties is to embed deterministic considerations in the probabilistic indices in order to monitor the system well-being. The system well-being can be designated as healthy, marginal and at risk. The concept of system well-being is examined and extended in this thesis to cover the overall area of operating reserve assessment. Operating reserve evaluation involves the two distinctly different aspects of unit commitment and the dispatch of the committed units. Unit commitment health analysis involves the determination of which unit should be committed to satisfy the operating criteria. The concepts developed for unit commitment health, margin and risk are extended in this thesis to evaluate the response well-being of a generating system. A procedure is presented to determine the optimum dispatch of the committed units to satisfy the response criteria. The impact on the response wellbeing being of variations in the margin time, required regulating margin and load forecast uncertainty are illustrated. The effects on the response well-being of rapid start units, interruptible loads and postponable outages are also illustrated. System well-being is, in general, greatly improved by interconnection with other power systems. The well-being concepts are extended to evaluate the spinning reserve requirements in interconnected systems. The interconnected system unit commitment problem is decomposed into two subproblems in which unit scheduling is performed in each isolated system followed by interconnected system evaluation

    Tokyo Electric Power Company (TEPCO), Kansai Electric Power Co., Inc., Tohoku Electric Power and other nine companies reported the results of innovations in techniques of electric power in 2008, Japan. J-Power started construction of the Ohma Nuclear Power Plant (power generating capacity: 1,383 MW, ABWR) in Ohma Town, Aomori prefecture, Japan, in May 2008. TEPCO developed the low vibration control valve and carried out the model experiments using air as fluid and the simulation by computational fluid dynamics. Mach number distribution (ε L =0.068) at the valve showed change of the supersonic jet flow as time advanced and a periodic pressure change on the valve and valve seat. Japan Atomic Power Company reported development of techniques for the established nuclear power station such as control of pipe thinning of the secondary system of PWR by insertion of oxygen at Tsuruga Power Station Unit 2, risk evaluation, the effects of increase of generating power on aging deterioration, and development of heat protective clothing. Researched are a power generation plant of small-and-medium-size reactors which took in reforming technology using the location to a narrow site, funds by stakeholders and the idea of future 'fast breeder reactor system', sodium-cooled loop type reactor, which uses TRU as fuel. The accumulator tank of new type safety system for Tsuruga Power Station Unit 3 and 4 is designed and tested. Decommissioning process of Tokai Power Plant and recycling of shielding materials, blocks and concrete powder are stated. (S.Y.)

    1979-06-01

    This inventory of small industrial electric generating systems was assembled by The Aerospace Corporation to provide a data base for analyses being conducted to estimate the potential for displacement of these fossil-fueled systems by solar thermal electric systems no larger than 10 MW in rated capacity. The approximately 2100 megawatts generating capacity of systems in this category constitutes a potential market for small solar thermal and other solar electric power systems. The sources of data for this inventory were the (former) Federal Power Commission (FPC) Form 4 Industrial Ledger and Form 12-C Ledger for 1976. Table 1 alphabetically lists generating systems located at industrial plants and at Federal government installations in each of the 50 states. These systems are differentiated by type of power plant: steam turbine, diesel generator, or gas turbine. Each listing is designated as a power system rather than a power unit because the FPC Ledgers do not provide a means of determining whether more than one unit is associated with each industrial installation. Hence, the user should consider each listing to be a system capacity rating wherein the system may consist of one or more generating units with less than 10 MW/sub e/ combined rating. (WHK)

    1981-01-01

    The plans of electric power supply for fiscal 1981 (from April, 1981, to March, 1982) by the power companies were formulated and submitted to the Ministry of International Trade and Industry. Along with the current up trend of economic activities, the demands of electric power will be on the increase. A summer peak of power consumption may rise all the more due to the increase in room-cooling units. On the other hand, the problem of petroleum is unsettled. Under the situation, the principal considerations behind the formulation of the plans are the effective utilization of other energy resources than oil and the suppression of oil-burning power generation, the economical usage of all power generation facilities and stabilized demand and supply, and the promotion of wide-area operation. The situation in fiscal 1981, power demands, power source facilities demand and supply balance, and the interchange of power among power companies are described. (J.P.N.)

  13. Power Consumption Analysis of Electrical Installations at Healthcare Facility

    2017-01-01

    Full Text Available This paper presents a methodology for power consumption estimation considering harmonic and interharmonic content and then it is compared to the power consumption estimation commonly done by commercial equipment based on the fundamental frequency, and how they can underestimate the power consumption considering power quality disturbances (PQD. For this purpose, data of electrical activity at the electrical distribution boards in a healthcare facility is acquired for a long time period with proprietary equipment. An analysis in the acquired current and voltage signals is done, in order to compare the power consumption centered in the fundamental frequency with the generalized definition of power consumption. The results obtained from the comparison in the power consumption estimation show differences between 4% and 10% of underestimated power consumption. Thus, it is demonstrated that the presence of harmonic and interharmonic content provokes a significant underestimation of power consumption using only the power consumption centered at the fundamental frequency.

  16. 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

    2010-08-01

    Full Text Available Electric power system is one of the most complex artificial systems in the world. The complexity is determined by its characteristics about constitution, configuration, operation, organization, etc. The fault in electric power system cannot be completely avoided. When electric power system operates from normal state to failure or abnormal, its electric quantities (current, voltage and angles, etc. may change significantly. Our researches indicate that the variable with the biggest coefficient in principal component usually corresponds to the fault. Therefore, utilizing real-time measurements of phasor measurement unit, based on principal components analysis technology, we have extracted successfully the distinct features of fault component. Of course, because of the complexity of different types of faults in electric power system, there still exists enormous problems need a close and intensive study.

    Conditions for wind power on a liberalised North European electrical power market are addressed in the paper. Results are presented from a recently completed study carried out by Risoe National Laboratory in collaboration with the Danish electric utilities Eltra, Elsam and Elkraft. A main result from the study is, that the market will be able to provide the necessary power regulation, that will be required year 2005 as consequence of the expected wind power capacity extension, according to the Danish energy plan, Energy21. The averege sales price on the market for the wind-generated electricity is less than the average spot market price, due to provision of power regulation to balance the unpredictability of the wind power. This reduction in the market value of wind power has been calculated to 10-20 DKK/MWh of 1.3-2.7 EUR/MWh. (au)

    2011-01-01

    The importance of renewable energy increases in activities relating to new forms of managing and operating electrical power: especially wind power. Wind generation is increasing its share in the electricity generation portfolios of many countries. Wind power production in Spain has doubled over the past four years and has reached 20 GW. One of the greatest problems facing wind farms is that the electrical power generated depends on the variable characteristics of the wind. To become competitive in a liberalized market, the reliability of wind energy must be guaranteed. Good local wind forecasts are therefore essential for the accurate prediction of generation levels for each moment of the day. This paper proposes an electrical power production model for wind farms based on a new method that produces correlated wind speeds for various wind farms. This method enables a reliable evaluation of the impact of new wind farms on the high-voltage distribution grid. (author)

    The application of electric power replacement plays an important role in promoting the development of energy conservation and emission reduction in our country. To exploit the potentiality of regional electric power replacement, the regional GDP (gross domestic product) and energy consumption are taken as potentiality evaluation indicators. The principal component factors are extracted with PCA (principal component analysis), and the integral potentiality analysis is made to the potentiality of electric power replacement in the national various regions; a region is taken as a research object, and the potentiality of electric power replacement is defined and quantified. The analytical model for the potentiality of multi-scenario electric power replacement is developed, and prediction is made to the energy consumption with the grey prediction model. The relevant theoretical research is utilized to realize prediction analysis on the potentiality amount of multi-scenario electric power replacement.

    1972-01-01

    The integrated engine-generator concept of locating an electric generator inside an aircraft turbojet or turbofan engine concentric with, and driven by, one of the main engine shafts is discussed. When properly rated, the generator can serve as an engine starter as well as a generator of electric power. The electric power conversion equipment and generator controls are conveniently located in the aircraft. Preliminary layouts of generators in a large engine together with their physical sizes and weights indicate that this concept is a technically feasible approach to aircraft secondary power.

  9. Equilibrium pricing in electricity markets with wind power

    Science.gov (United States)

    Rubin, Ofir David

    Estimates from the World Wind Energy Association assert that world total wind power installed capacity climbed from 18 Gigawatt (GW) to 152 GW from 2000 to 2009. Moreover, according to their predictions, by the end of 2010 global wind power capacity will reach 190 GW. Since electricity is a unique commodity, this remarkable expansion brings forward several key economic questions regarding the integration of significant amount of wind power capacity into deregulated electricity markets. The overall dissertation objective is to develop a comprehensive theoretical framework that enables the modeling of the performance and outcome of wind-integrated electricity markets. This is relevant because the state of knowledge of modeling electricity markets is insufficient for the purpose of wind power considerations. First, there is a need to decide about a consistent representation of deregulated electricity markets. Surprisingly, the related body of literature does not agree on the very economic basics of modeling electricity markets. That is important since we need to capture the fundamentals of electricity markets before we introduce wind power to our study. For example, the structure of the electric industry is a key. If market power is present, the integration of wind power has large consequences on welfare distribution. Since wind power uncertainty changes the dynamics of information it also impacts the ability to manipulate market prices. This is because the quantity supplied by wind energy is not a decision variable. Second, the intermittent spatial nature of wind over a geographical region is important because the market value of wind power capacity is derived from its statistical properties. Once integrated into the market, the distribution of wind will impact the price of electricity produced from conventional sources of energy. Third, although wind power forecasting has improved in recent years, at the time of trading short-term electricity forwards, forecasting

  10. Consequences of reduced production of electricity in nuclear power plants

    International Nuclear Information System (INIS)

    The Swedish Power Administration has assessed the possibilities of expanding electric power sources other than nuclear power plants for the years 1980 and 1985. Reports on costs in the form of loss of capital and increased operating costs involved in the dismantling of nuclear power plants are made in Supplement 1. The economics division of the Finance Department, starting with a long-range study model of the Swedish economy, has calculated the consequences of a cutback in electric power up to 1980 for Sweden's economy and employment in that year. The consequences of reduction of electricity supplies up to 1985 are summarized in Supplement 2 in this report. It is concluded that in order to be able to manage the problem of supplying electricity by 1985, it will be necessary to increase oil power above what was assumed in the energy policy program. There will have to be new oil-based power as well. According to the Power Administration, oil-power facilities can be expanded to varying degrees, depending upon when the decision is made. The Power Administration's calculations show that 125 TWh is possible in 1985 without nuclear power only if a decision for discontinuation is made in the fall of 1976. This is based on very optimistic assumptions about the time of execution of a program for oil-steam operation, and also on the assumption that extreme measures will be initiated to force expansion of both district-heating distribution and power + heat facilities. Oil consumption for production of electricity in such an electric power system would be about 9 million m 3 , which is about 5 times more than at present and about one-third of the present total consumption of petroleum products in Sweden

    An electrical prototype power processor unit was designed, fabricated and tested with a 30 cm mercury ion engine for primary space propulsion. The power processor unit used the thyristor series resonant inverter as the basic power stage for the high power beam and discharge supplies. A transistorized series resonant inverter processed the remaining power for the low power outputs. The power processor included a digital interface unit to process all input commands and internal telemetry signals so that electric propulsion systems could be operated with a central computer system. The electrical prototype unit included design improvement in the power components such as thyristors, transistors, filters and resonant capacitors, and power transformers and inductors in order to reduce component weight, to minimize losses, and to control the component temperature rise. A design analysis for the electrical prototype is also presented on the component weight, losses, part count and reliability estimate. The electrical prototype was tested in a thermal vacuum environment. Integration tests were performed with a 30 cm ion engine and demonstrated operational compatibility. Electromagnetic interference data was also recorded on the design to provide information for spacecraft integration.

    Electric power theft is a problem that continues to plague power sector across the whole country. Every year, the electricity companies face the line losses at an average 20-30% and according to power ministry estimation WAPDA companies lose more than Rs. 125 billion. Significantly, it is enough to destroy the entire power sector of country. According to sources 20% losses means the masses would have to pay extra 20% in terms of electricity tariffs. In other words, the innocent consumers pay the bills of those who steal electricity. For all that, no any permanent solution for this major issue has ever been proposed. We propose an applicable and optimum solution for this impassable problem. In our research, we propose an Electric power theft solution based on three stages; Transmission stage, Distribution stage, and User stage. Without synchronization among all, the complete solution can not be achieved. The proposed solution is simulated on NI (National Instruments) Circuit Design Suite Multisim v.10.0. Our research work is an implicit and a workable approach towards the Electric power theft, as for conditions in Pakistan, which is bearing the brunt of power crises already. (author)

    High-power lasers in space could provide power for a variety of future missions such as spacecraft electric power requirements and laser propulsion. This study investigates four electrically pumped laser systems, all scaled to 1-MW laser output, that could provide power to spacecraft. The four laser systems are krypton fluoride, copper vapor, laser diode array, and carbon dioxide. Each system was powered by a large solar photovoltaic array which, in turn, provided power for the appropriate laser power conditioning subsystem. Each system was block-diagrammed, and the power and efficiency were found for each subsystem block component. The copper vapor system had the lowest system efficiency (6 percent). The CO2 laser was found to be the most readily scalable but has the disadvantage of long laser wavelength.

    The U.S. Department of Energy (DOE) provides funding and technical support for a broad array of energy projects. Included among these projects are those designed to demonstrate cleaner and more efficient uses for coal, both for electric power generation and to meet industrial needs. These projects are part of the seven billion dollar Clean Coal Technology (CCT) Program, jointly funded by government and industry. When the DOE proposes to fund a project in whole or in part, such as those undertaken as part of the CCT Program in cooperation with an industrial partner, the Federal decision (whether to fund or not), triggers the need for DOE to comply with the National Environmental Policy Act of 1969 (NEPA). NEPA mandates that Federal agencies evaluate the potential environmental impacts of their proposed action and reasonable alternatives prior to making a decision on whether to undertake the action. Impacts to air quality are usually the most important concern of a CCT proposal. Based on about three dozen impact evaluations we have supported, we have learned a good deal about analyzing air quality impacts for CCT projects. We will discuss our experiences, including the difference between regulatory requirements and NEPA review requirements, and issues raised by the 1990 Clean Air Act Amendments (CAAA) such as air toxics, source categories, maximum achievable control technology, new source review, citizen suits and the bounty system, conformity, acidic deposition, global climate change, radionuclides, visibility, and public involvement. We will close with examples of how NEPA review has resulted in beneficial changes to proposed CCT projects through mitigation measures designed to meet our Nation's air quality goals

    Recently, deregulation and reform of electric power utilities have been progressing in many parts of the world. In Japan, partial deregulation has been started from generation sector since 1995 and partial deregulation of retail sector is executed through twice law revisions. Through the deregulation, because electric power is traded in the market and its price is always fluctuated, it is important for the electric power business to analyze and predict the price. Although the price data of the electric power market is time series data, it is not always proper to analyze by the linear model such as ARMA because the price sometimes changes suddenly. Therefore, in this paper, we apply the methods of chaotic time series analysis, one of non-linear analysis methods, and investigate the chaotic characteristics of the system price of JEPX.

    Every manner to generate electricity has effects on environment and on the way of life of human society. Nevertheless electricity is a way of secondary energy handy and clean and is also frequently the more efficient, and for its reason its use is growing in countries with a rate superior to the increase in national gross product. This is particularly remarkable in Mexico where still exist population sectors without electricity services and where the demand per capita is left behind with respect to other economic indicators. In the last years, preoccupation for environmental effects in human activities, especially that related with the production and use of energy, has been increasing. 'Acid rain', air and water pollution, destruction of stratospheric ozone layer, global heating, radioactive wastes storage, land use, destruction of tropical forest, inundation of archaeological ruins, extintion of animal and vegetable species, are examples of problems daily expound to society (Author)

    The increased requirements on supervision, control, and performance in modern power systems make power quality monitoring a common practise for utilities. Large databases are created and automatic processing of the data is required for fast and effective use of the available information. Aim of the work presented in this paper is the development of tools for analysis of monitoring power quality data and in particular measurements of voltage and currents in various level of electrical power distribution. The study is extended to evaluate the reliability of the electrical system in nuclear plant. Power Quality is a measure of how well a system supports reliable operation of its loads. A power disturbance or event can involve voltage, current, or frequency. Power disturbances can originate in consumer power systems, consumer loads, or the utility. The effect of power quality problems is the loss power supply leading to severe damage to equipments. So, we try to track and improve system reliability. The assessment can be focused on the study of impact of short circuits on the system, harmonics distortion, power factor improvement and effects of transient disturbances on the Electrical System during motor starting and power system fault conditions. We focus also on the review of the Electrical System design against the Nuclear Directorate Safety Assessment principles, including those extended during the last Fukushima nuclear accident. The simplified configuration of the required system can be extended from this simple scheme. To achieve these studies, we have used a demo ETAP power station software for several simulations.

  20. Impacts on irrigated agriculture of changes in electricity costs resulting from Western Area Power Administration's power marketing alternatives

    1995-03-01

    Irrigation is a major factor in the growth of US agricultural productivity, especially in western states, which account for more than 85% of the nation's irrigated acreage. In some of these states, almost all cropland is irrigated, and nearly 50% of the irrigation is done with electrically powered pumps. Therefore, even small increases in the cost of electricity could have a disproportionate impact on irrigated agriculture. This technical memorandum examines the impacts that could result from proposed changes in the power marketing programs of the Western Area Power Administration's Salt Lake City Area Office. The changes could increase the cost of power to all Western customers, including rural municipalities and irrigation districts that rely on inexpensive federal power to pump water. The impacts are assessed by translating changes in Western's wholesale power rate into changes in the cost of pumping water as an input for agricultural production. Farmers can adapt to higher electricity prices in many ways, such as (1) using different pumping fuels, (2) adding workers and increasing management to irrigate more efficiently, and (3) growing more drought-tolerant crops. This study projects several responses, including using less groundwater and planting fewer waterintensive crops. The study finds that when dependence on Western's power is high, the cost of power can have a major effect on energy use, agricultural practices, and the distribution of planted acreage. The biggest percentage changes in farm income would occur (1) in Nevada and Utah (however, all projected changes are less than 2% of the baseline) and (2) under the marketing alternatives that represent the lowest capacity and energy offer considered in Western's Electric Power Marketing Environmental Impact Statement. The aggregate impact on farm incomes and the value of total farm production would be much smaller than that suggested by the changes in water use and planted acreage

  3. Does wind energy mitigate market power in deregulated electricity markets?

    International Nuclear Information System (INIS)

    Ben-Moshe, Ori; Rubin, Ofir D.

    2015-01-01

    A rich body of literature suggests that there is an inverse relationship between wind power penetration rate into the electricity market and electricity prices, but it is unclear whether these observations can be generalized. Therefore, in this paper we seek to analytically characterize market conditions that give rise to this inverse relationship. For this purpose, we expand a recently developed theoretical framework to facilitate flexibility in modeling the structure of the electric industry with respect to the degree of market concentration and diversification in the ownership of wind power capacity. The analytical results and their attendant numerical illustrations indicate that the introduction of wind energy into the market does not always depress electricity prices. Such a drop in electricity prices is likely to occur when the number of firms is large enough or the ownership of wind energy is sufficiently diversified, or most often a combination of the two. Importantly, our study defines the circumstances in which the question of which type of firm invests in wind power capacity is crucial for market prices. - Highlights: • Studies show that electricity prices decrease with increased wind power capacity. • We investigate market conditions that give rise to this inverse relationship. • Average prices for wind energy are systematically lower than average market prices. • Conventional generation firms may increase market power by investing in wind farms. • Energy policy should seek to diversify the ownership of wind power capacity

    Full Text Available Electric vehicles (EV, Hybrid Electric Vehicles (HEV or Plug-in Hybrid Electric Vehicles (PHEV are believed to be a promising substitute for current gas-propelled vehicles. Previous research studied the attributes of different types of EVs and confirmed their advantages. The feasibility of EVs has also been explored using simulation, retrospective survey data, or a limited size of field travel data. In this study, naturalistic driving data collected from more than 100 drivers during one year are used to explore naturalistic driver travel patterns. Typical travel distance and time and qualified dwell times (i.e., the typical required EV battery recharging time between travels as based on most literature findings are investigated in this study. The viability of electric cars is discussed from a pragmatic perspective. The results of this research show that 90 percent of single trips are less than 25 miles; approximately 70 percent of the average annual daily travel is less than 60 miles. On average there are 3.62 trips made between four-hour dwell times as aggregated to 60 minutes and 50 miles of travel. Therefore, majority of trips are within the travel range provided by most of the currently available EVs. A well-organized schedule of recharging will be capable of covering even more daily travels.

    1998-01-01

    The problems of long-distance electric power transmission and losses connected with them are discussed. It is shown that direct current power transmission lines are the most promising for nuclear power engineering as they assure NPP scheduled operating conditions and independence of consumer's load variations. Nowadays the direct current power transmission lines for the voltage of ± 750 kV are developed and adopted in every day practice. Energy losses in long-distance power transmission and its cost are estimated. On this basis the conclusion is made that high serviceability and reliability of the direct current power transmission lines will lead to their development and introduction as the most prospective electric power supply systems in the nearest decade

  12. The effects of electric power industry restructuring on the safety of nuclear power plants in the United States

    Science.gov (United States)

    Butler, Thomas S.

    Throughout the United States the electric utility industry is restructuring in response to federal legislation mandating deregulation. The electric utility industry has embarked upon an extraordinary experiment by restructuring in response to deregulation that has been advocated on the premise of improving economic efficiency by encouraging competition in as many sectors of the industry as possible. However, unlike the telephone, trucking, and airline industries, the potential effects of electric deregulation reach far beyond simple energy economics. This dissertation presents the potential safety risks involved with the deregulation of the electric power industry in the United States and abroad. The pressures of a competitive environment on utilities with nuclear power plants in their portfolio to lower operation and maintenance costs could squeeze them to resort to some risky cost-cutting measures. These include deferring maintenance, reducing training, downsizing staff, excessive reductions in refueling down time, and increasing the use of on-line maintenance. The results of this study indicate statistically significant differences at the .01 level between the safety of pressurized water reactor nuclear power plants and boiling water reactor nuclear power plants. Boiling water reactors exhibited significantly more problems than did pressurized water reactors.

  17. Using peer-to-peer energy-trading platforms to incentivize prosumers to form federated power plants

    Morstyn, Thomas; Farrell, Niall; Darby, Sarah J.; McCulloch, Malcolm D.

    2018-02-01

    Power networks are undergoing a fundamental transition, with traditionally passive consumers becoming `prosumers' — proactive consumers with distributed energy resources, actively managing their consumption, production and storage of energy. A key question that remains unresolved is: how can we incentivize coordination between vast numbers of distributed energy resources, each with different owners and characteristics? Virtual power plants and peer-to-peer (P2P) energy trading offer different sources of value to prosumers and the power network, and have been proposed as different potential structures for future prosumer electricity markets. In this Perspective, we argue they can be combined to capture the benefits of both. We thus propose the concept of the federated power plant, a virtual power plant formed through P2P transactions between self-organizing prosumers. This addresses social, institutional and economic issues faced by top-down strategies for coordinating virtual power plants, while unlocking additional value for P2P energy trading.

    2017-11-01

    In article the analysis of electric power consumption and problems of power saving on coal mines are considered. Nowadays the share of conditionally constant costs of electric power for providing safe working conditions underground on coal mines is big. Therefore, the power efficiency of underground coal mining depends on electric power expense of the main technological processes and size of conditionally constant costs. The important direction of increase of power efficiency of coal mining is forecasting of a power consumption and monitoring of electric power expense. One of the main approaches to reducing of electric power costs is increase in accuracy of the enterprise demand in the wholesale electric power market. It is offered to use artificial neural networks to forecasting of day-ahead power consumption with hourly breakdown. At the same time use of neural and indistinct (hybrid) systems on the principles of fuzzy logic, neural networks and genetic algorithms is more preferable. This model allows to do exact short-term forecasts at a small array of input data. A set of the input parameters characterizing mining-and-geological and technological features of the enterprise is offered.

    1992-01-01

    One of the main aims of the Norwegian government is to make the electric power market more effective. A new energy law has been passed and other initiatives have been taken which have altered the framework of the conditions for electricity production and sales in Norway. The proposition for trading electric power and the development of new policies for calculating transmission tariffs has been dealt with in addition to plans for the extent of the development of hydroelectric power. Norway is the world's sixth largest producer of hydroelectricity. The domestic supply of electricity is described as well as the nature of the reorganization of the transmission of electricity and Norwegian foreign trade proposals within this area. The government is interested in taxing with regard to production instead of on the power itself in order to stimulate better energy economy. It is important that this will have a neutral effect between export and domestic consumption when contract sales to abroad are initiated. A more efficient electric power market will profit Norwegian society. Statistical data are included. (AB)

  5. Two essays on real-time pricing of electric power

    Science.gov (United States)

    Gupta, Nainish Kumar

    1997-09-01

    This dissertation contains two essays on a new innovative pricing mechanism in the electric power industry known as Real Time Pricing (RTP). RTP is a method of pricing electric power wherein at least one component of the price is set at or near levels that reflect the marginal costs of providing power during each time-specific interval. These prices vary in accord with time-specific, incremental supplier costs. RTP allows customers to manage their own bills by adjusting their consumption as spot prices and supplier costs vary, which may amount during a single day from 2 cents to 85 cents for one kilowatt hour (kWh) of usage. Using 1995 data the hypothesis that industrial customers shift their usage patterns of electricity in response to real time prices is tested. To measure customer responsiveness to real time electric rates, econometric techniques are applied to estimate demand elasticities.

  6. Electric power bidding model for practical utility system

    Directory of Open Access Journals (Sweden)

    M. Prabavathi

    2018-03-01

    Full Text Available A competitive open market environment has been created due to the restructuring in the electricity market. In the new competitive market, mostly a centrally operated pool with a power exchange has been introduced to meet the offers from the competing suppliers with the bids of the customers. In such an open access environment, the formation of bidding strategy is one of the most challenging and important tasks for electricity participants to maximize their profit. To build bidding strategies for power suppliers and consumers in the restructured electricity market, a new mathematical framework is proposed in this paper. It is assumed that each participant submits several blocks of real power quantities along with their bidding prices. The effectiveness of the proposed method is tested on Indian Utility-62 bus system and IEEE-118 bus system. Keywords: Bidding strategy, Day ahead electricity market, Market clearing price, Market clearing volume, Block bid, Intermediate value theorem

  8. Influence of wind power, plug-in electric vehicles, and heat storages on power system investments

    International Nuclear Information System (INIS)

    Kiviluoma, Juha; Meibom, Peter

    2010-01-01

    Due to rising fuel costs, the substantial price for CO 2 emissions and decreasing wind power costs, wind power might become the least expensive source of power for an increasing number of power systems. This poses the questions of how wind power might change optimal investments in other forms of power production and what kind of means could be used to increase power system flexibility in order to incorporate the variable power production from wind power in a cost-effective manner. We have analysed possible effects using an investment model that combines heat and power production and simulates electric vehicles. The model runs in an hourly time scale in order to accommodate the impact of variable power production from wind power. Electric vehicles store electricity for later use and can thus serve to increase the flexibility of the power system. Flexibility can also be upgraded by using heat storages with heat from heat pumps, electric heat boilers and combined heat and power (CHP) plants. Results show that there is great potential for additional power system flexibility in the production and use of heat. (author)

    2011-01-01

    New technologies will enable households to generate an increasing amount of their own electricity. Intentions to generate own power are a preliminary step towards actual behavior. Because own generation is still very limited and the behavior of early adopters may not be representative for the complete population, our study focuses on intentions rather than actual behavior. A consumer survey among 2047 Dutch households reveals that environmental concerns are the most important driver of a household's intention to generate its own power. Affinity with technology and energy and the reputation of electricity companies are also significant drivers, but financial factors and power outages are not. About 40% of Dutch households have an intention to generate their own power, with an overrepresentation of young households. This group falls apart in two sub segments; for the 'generating savers' (21%) a high intention to generate own power coincides with a high intention to save energy, whereas generating users (18%) combine a high intention to generate own power with a low intention to save energy. - Highlights: → A consumer survey studies household intentions to generate own power. → Environmental concerns are the most important motive for generating own power. → Other drivers are affinity with technology and reputation of electricity companies. → About 40% of Dutch households feel a need to generate their own electricity.

  17. The role of nuclear power in securing stable electricity supply in a liberalized electricity market

    International Nuclear Information System (INIS)

    Lee, M. K.; Mun, K. H.; Kim, S. S.

    2001-01-01

    Market liberalization has an influence on the investment environment. According to the option value analysis, uncertainty in investment decision tends to make small sized power plant more favourable because of its short lead time in construction and of low capital investment. These small sized power plants are largely using fossil fuel under current generation technology. If Korean electric system becomes dependent heavily on fossil fuel fired power plant, stable supply of fossil fuel will be very essential to secure stable electricity supply. Taking into consideration these circumstances, the introduction of additional nuclear power plant is needed, because its fuel cost is small comparing other power options. Therefore, it is required that nuclear sector remain public company as reflected in the current liberalization plan of Korean Electric Power Corporation

    Hennings, Wilfried; Mischinger, Stefan; Linssen, Jochen

    2013-01-01

    This article describes the assessment of future wind power utilization for charging electric vehicles (EVs) in Germany. The potential wind power production in the model years 2020 and 2030 is derived by extrapolating onshore wind power generation and offshore wind speeds measured in 2007 and 2010 to the installed onshore and offshore wind turbine capacities assumed for 2020 and 2030. The energy consumption of an assumed fleet of 1 million EVs in 2020 and 6 million in 2030 is assessed using detailed models of electric vehicles, real world driving cycles and car usage. It is shown that a substantial part of the charging demand of EVs can be met by otherwise unused wind power, depending on the amount of conventional power required for stabilizing the grid. The utilization of wind power is limited by the charging demand of the cars and the bottlenecks in the transmission grid. -- Highlights: •Wind power available for charging depends on minimum required conventional power (must-run). •With 20 GW must-run power, 50% of charging can be met by excess wind power. •Grid bottlenecks decrease charging met by wind power from 50 % to 30 %. •With zero must-run power, only very little wind power is available for charging

  19. Impacts of Federal Tax Credit Extensions on Renewable Deployment and Power Sector Emissions

    Federal tax credits for renewable energy (RE) have served as one of the primary financial incentives for RE deployment over the last two decades in the United States. In December 2015, the wind power production tax credit and solar investment tax credits were extended for five years as part of the Consolidated Appropriations Act of 2016. This report explores the impact that these tax credit extensions might have on future RE capacity deployment and power sector carbon dioxide (CO2) emissions. The analysis examines the impacts of the tax credit extensions under two distinct natural gas price futures as natural gas prices have been key factors in influencing the economic competitiveness of new RE development. The analysis finds that, in both natural gas price futures, RE tax credit extensions can spur RE capacity investments at least through the early 2020s and can help lower emissions from the U.S. electricity system. More specifically, the RE tax credit extensions are estimated to drive a net peak increase of 48-53 GW in installed RE capacity in the early 2020s -- longer term impacts are less certain. In the longer term after the tax credits ramp down, greater RE capacity is driven by a combination of assumed RE cost declines, rising fossil fuel prices, and other clean energy policies such as the Clean Power Plan. The tax credit extension-driven acceleration in RE capacity development can reduce fossil fuel-based generation and lower electric sector CO2 emissions. Cumulative emissions reductions over a 15-year period (spanning 2016-2030) as a result of the tax credit extensions are estimated to range from 540 to 1420 million metric tonnes CO2. These findings suggest that tax credit extensions can have a measurable impact on future RE deployment and electric sector CO2 emissions under a range of natural gas price futures.

    Prospective missions requiring large power supplies that might be satisfied with space nuclear reactors (SNR) are discussed, along with design concepts and problems and other potential high-power space systems. Having a minimum economic output of 10 kWe, SNR seem well-suited as the power sources for DBS systems, space-based ATC systems manned planetary missions, an expanding Space Station, materials processing, and outer planets missions. SNR avoid the large area problems of solar cell arrays, short lifetimes of thermionic converters, and vibration and heat control in Stirling engines. Design problems exist for SNR in the heat transfer and rejection systems, radioactive emissions and degradation of reactor materials, and size. The latter is a function of Shuttle payload constaints and raises the possibility of having to load the fuel while in orbit. The earliest operational date of SNRs is projected for the early 1990s, if progress is good in the current SP-100 program.

    2014-01-01

    Highlights: • We analyze the pricing systems and wind power trading in electricity markets. • We propose a model that captures the relation between market prices and wind power. • A probabilistic bidding model can increase profits for wind power producers. • Profit maximizing bidding strategies carry risks for power system operators. • We conclude that modifications of current market designs may be needed. - Abstract: Objective: The optimal day-ahead bidding strategy is studied for a wind power producer operating in an electricity market with high wind penetration. Methods: A generalized electricity market is studied with minimal assumptions about the structure of the production, bidding, or consumption of electricity. Two electricity imbalance pricing schemes are investigated, the one price and the two price scheme. A stochastic market model is created to capture the price effects of wind power production and consumption. A bidding algorithm called SCOPES (Supply Curve One Price Estimation Strategy) is developed for the one price system. A bidding algorithm called MIMICS (Multivariate Interdependence Minimizing Imbalance Cost Strategy) is developed for the two price system. Results: Both bidding strategies are shown to have advantages over the assumed “default” bidding strategy, the point forecast. Conclusion: The success of these strategies even in the case of high deviation penalties in a one price system and the implicit deviation penalties of the two price system has substantial implications for power producers and system operators in electricity markets with a high level of wind penetration. Practice implications: From an electricity market design perspective, the results indicate that further penalties or regulations may be needed to reduce system imbalance

    The Finnish State has traditionally controlled the import of electricity, larger related investments and pricing. Lately, a market orientated economic policy has influenced energy policy and the amount of state control has gradually decreased. Decisions have yet to be made with regard to the fifth nuclear power reactor. The paper deals briefly with the subjects of the electric power, natural gas and oil markets. Finland's transmission network has connections to the former Russia and the Baltic countries. According to agreements within the European Community, Finland must now make changes in its electric power supply structure. Competition will be encouraged and monopolies discouraged. Pricing shall be transparent, and power plants must present written documentation for their management system, price regulations etc. A law must be passed to legitimate trade across the country's borders. Emphasis will be laid on energy conservation and energy research and consultant services. It is claimed that Finland's level of technology in this area lives up to international standards. (AB)

The results show that electric vehicles (EVs) have the ability to balance the electricity demand and supply and to further the wind power integration. In the best case, the energy system with EV can increase wind power...... with this imbalance and to reduce its high dependence on oil production. For this reason, it is interesting to analyse the extent to which transport electrification can further the renewable energy integration. This paper quantifies this issue in Inner Mongolia, where the share of wind power in the electricity supply...... integration by 8%. The application of EVs benefits from saving both energy system cost and fuel cost. However, the negative consequences of decreasing energy system efficiency and increasing the CO2 emission should be noted when applying the hydrogen fuel cell vehicle (HFCV). The results also indicate...

    Ongoing theft, corruption, and an artificially decreased pricing structure have made it nearly impossible for the state utilities in India to improve power service. As a result, industrial consumers across India exit the state-run system and rely on their own on-site power generation in order to ensure a consistent and reliable source of electricity. The 2003 Electricity Act encourages further power production from these captive plants through its open access clause. By encouraging the growth of these captive power plants, politicians in India set up a dual-track economy, whereby state-run and market-run production exist side-by-side. This strategy allows politicians to encourage private sector involvement in the electricity market, without jeopardizing the support of key political constituencies at the state level. (author)

    1999-01-01

    The factors influencing the initial market pricing in the early years of Ontario's new electricity market were discussed with particular insight on the potential for near term development of independent power and cogeneration. The major factors influencing prices include: (1) no increase in retail prices, (2) financial restructuring of Ontario Hydro, (3) the Market Power Mitigation Agreement, (4) tighter power plant emissions standards, and (5) an electricity supply and demand balance. Generation competition is not expected to influence market pricing in the early years of the new electricity market. Prices will instead reflect the restructuring decisions of the Ontario government. The decision to have Ontario Power Generation Inc. (OPGI) as a single generator for Ontario Hydro's generation assets will ensure that average spot market pricing in the early market years will be close to a 3.8 c/kWh revenue cap

    Long known for its vast scale and fierce resistance to change, the US power industry is poised for a sweeping transformation. Although driven by many of the same forces propelling the telecommunications revolution, the electricity industry has received only a fraction as much attention. Yet the electric industry is far larger, with a current investment per customer of $6,000--double that of the phone and cable industries combined. Moreover, unlike telecommunications, the future of the power industry will have an enormous impact on the global environment. The glimmerings of a more efficient, decentralized, and less-polluting power system are beginning to capture the interest--and even the investment dollars--of some. In this paper, the authors describe the route to a more environmentally sustainable electric industry to power the twenty-first century

    In the seemingly endless discussions about the pros and cons of wind power even its advocates have to agree that though wind can fly, with offshore wind farms soon to become reality, this only exacerbates the problem of the winds changeability. Even now the major producers of electricity and power grid companies foresee grave difficulties from the peaks and dips in supply of this green power source.

    Thabit, S. S.; Stark, J.

    This paper investigates the impact of the provisions of the new Energy Act, 1983 on industrial wind-powered private generators of electricity and the effects of published tariffs on various industrial working patterns. Up to 30 percent savings can be achieved in annual electricity bill costs for an industrial generator/user of electricity working a single daily shift, if located in a favorable, 7 m/s mean annual wind speed regime. Variation of the availability charge between Electricity Boards about a base value of 0.70 pounds sterling/kVA was found to have insignificant (+ or - 1.3 percent) impact on total electricity bill costs. It was also shown that for industrial users of electricity, the simpler two-rate purchase terms were commercially adequate when compared with the four-rate alternative where expensive metering becomes necessary.

  16. Nuclear energy resources for electrical power generation

    'Nuclear Energy Resources' is interpreted as the nuclear power systems currently available commercially and those at an advanced stage of development, together with full and associated resources required to implement large-scale nuclear programs. Technical advantages and disadvantages of the established power reactor systems are reviewed, and the uranium fuel situation is outlined in terms of supply and demand, the relationship of resources to the requiremnts of current reactor types, and the likely future implications of the Fast Breeder Reactor (FBR). Because of its importance for the future, the problems, status, and likely time scale of the FBR are discussed in some detail. It is concluded that the most important areas for nearterm attention in Australia are the criteria and conditions that would apply to nuclear installations, and the possible development of uranium fuel cycle industries. The pattern of development of reactor and fuel cycle strategies overseas is important for uranium industry planning, and in the long term plutonium availability may be a key factor in power and energy planning. Finally, acceptance of nuclear power includes acceptance that its radioactive wastes will have to be stored on earth, and recent developments to demonstrate that this can be done safely and economically are very important in terms of longterm public attitudes.

    Full text: Total installed electric power output of the existing thermal electric power plants in Uzbekistan is reaches 12 GW. Thermal electric power plants, working on organic fuel, produce around 88 % of the electricity in the country. The emission coefficient of CO 2 gases is 620 gram/kwph. Average electric efficiency of the thermal electric power plants is 32.1 %. The mentioned above data certifies, that the existing thermal electric power plants of Uzbekistan are physically and morally aged and they need to be retrofitted. Retrofitting of the existing thermal electric power plants can be done by several ways such as via including gas turbine toppings, by using solar technologies, etc. Solar thermal power is a relatively new technology which has already shown its enormous promise. With few environmental impacts and a massive resource, it offers a comparable opportunity to the sunniest Uzbekistan. Solar thermal power uses direct sunlight, so it must be sited in regions with high direct solar radiation. In many regions, one square km of land is enough to generate as much as 100-120 GWh of electricity per year using the solar thermal technology. This is equivalent to the annual production of a 50 MW conventional coal or gas-fired mid-load power plant. Solar thermal power plants can be designed for solar-only or for hybrid operation. Producing electricity from the energy in the sun's rays is a straightforward process: direct solar radiation can be concentrated and collected by a range of Concentrating Solar Power technologies to provide medium- to high temperature heat. This heat is then used to operate a conventional power cycle, for example through a steam turbine or a Stirling engine. Solar heat collected during the day can also be stored in liquid or solid media such as molten salts, ceramics, concrete or, in the future, phase-changing salt mixtures. At night, it can be extracted from the storage medium thereby continuing turbine operation. Currently, the

    When disaster strikes, electric power is usually the first critically important service to be lost. After several years of research and development, portable electric generator sets (gensets) are now entering the marketplace. The new gensets make use of solar electric panels known as photovoltaics (PV) to produce electricity. These gensets are reliable, safe to operate, highly mobile and will supply much-needed power for emergency response teams.

    The prospects for the development of the electric power industry of Russia adopted at a regular stage of working out the Energy Strategy and the General Plan of Distribution of the Electric Power Facilities are discussed. The monitoring of the progress in the implementation of the Energy Strategies for the periods until 2020 and 2030 adopted in 2003 and 2009 has, in general, validated the correctness of the estimated volumes of the energy resource production under overestimation of the expected domestic demand owing to an excessively optimistic forecast of the real development of the economy. The priority lines of the national energy policy in electric power and allied industries proposed in the Energy Strategy for the period until 2035 are considered. The tools for implementation of most of the proposals and the effectiveness of their implementation have yet to be defined more concretely. The development of the energy sector and the electric power industry under the conservative and optimistic scenarios of the development of the country's economy has been predicted using the SCANER modeling and information system, viz., the dynamics of the domestic consumption, export, and production of the primary energy and the electric power has been determined and the commissioning and structure of the required generating capacities and the consumption of the basic types of the energy resources by the electric power industry and the centralized heat supply systems has been optimized. Changes in the economic efficiency of the nuclear and thermal power plants under the expected improvements on their cost and performance characteristics and an increase in the domestic fuel prices are presented. The competitiveness of the wind and solar power production under Russian conditions has been evaluated considering the necessity of reservation and partial duplication of their capacities when operated in the power supply systems. When optimizing the electric power industry as a subsystem
