Catalog of DC Appliances and Power Systems Catalog of DC Appliances and Power Systems Title Catalog of DC Appliances and Power Systems Publication Type Report LBNL Report Number LBNL-5364E Year of Publication 2011 Authors Garbesi, Karina, Vagelis Vossos, and Hongxia Shen Document Number LBNL-5364E Date Published October Publisher Lawrence Berkeley National Laboratory Abstract This document catalogs the characteristics of current and potential future direct current (DC) products and power systems. It is part of a larger U.S. Department of Energy-funded project, "Direct-DC Power Systems for Energy Efficiency and Renewable Energy Integration with a Residential and Small Commercial Focus". That project is investigating the energy-savings potential, benefits, and barriers of using DC generated by on-site renewable energy systems directly in its DC form, rather than converting it first to alternating current (AC) for distribution to loads. Two related reports resulted from this work: this Catalog and a companion report that addresses direct-DC energy savings in U.S. residential buildings.Interest in 'direct-DC' is motivated by a combination of factors: the very rapid increase in residential and commercial photovoltaic (PV) power systems in the United States; the rapid expansion in the current and expected future use of energy efficient products that utilize DC power internally; the demonstrated energy savings of direct-DC in commercial data centers; and the current emergence of direct-DC power standards and products designed for grid-connected residential and commercial products. Based on an in-depth study of DC appliances and power systems, we assessed off-grid markets for DC appliances, the DC compatibility of mainstream electricity end-uses, and the emerging mainstream market for direct-DC appliances and power systems.

Power marketing and renewable energy  

SciTech Connect

Power marketing refers to wholesale and retail transactions of electric power made by companies other than public power entities and the regulated utilities that own the generation and distribution lines. The growth in power marketing has been a major development in the electric power industry during the last few years, and power marketers are expected to realize even more market opportunities as electric industry deregulation proceeds from wholesale competition to retail competition. This Topical Issues Brief examines the nature of the power marketing business and its relationship with renewable power. The information presented is based on interviews conducted with nine power marketing companies, which accounted for almost 54% of total power sales by power marketers in 1995. These interviews provided information on various viewpoints of power marketers, their experience with renewables, and their respective outlooks for including renewables in their resource portfolios. Some basic differences exist between wholesale and retail competition that should be recognized when discussing power marketing and renewable power. At the wholesale level, the majority of power marketers stress the commodity nature of electricity. The primary criteria for developing resource portfolios are the same as those of their wholesale customers: the cost and reliability of power supplies. At the retail level, electricity may be viewed as a product that includes value-added characteristics or services determined by customer preferences.

Market concentration and marketing power among electricity generators in Texas  

SciTech Connect

Policy initiatives designed to foster competition among electricity generators in Texas face a special challenge due to the relative isolation of that system. This isolation contributes to high levels of market concentration and market power that could hinder the development of a truly competitive market. This paper examines market concentration and market power in the ERCOT market for electricity generation by calculating the Herfindahl-Hirschman index (HHI) under various assumptions to gauge the degree of market concentration among generators in ERCOT. In addition, some ongoing studies of market power in ERCOT are discussed. The distinction between market concentration and market power is highlighted.

Market power in electricity markets: Beyond concentration measures  

SciTech Connect

The wave of electricity market restructuring both within the US and abroad has brought the issue of horizontal market power to the forefront of energy policy. Traditionally, estimation and prediction of market power has relied heavily on concentration measures. In this paper, the authors discuss the weaknesses of concentration measures as a viable measure of market power in the electricity industry, and they propose an alternative method based on market simulations that take advantage of existing plant level data. The authors discuss results from previous studies they have performed, and present new results that allow for the detection of threshold demand levels where market power is likely to be a problem. In addition, the authors analyze the impact of that recent divestitures in the California electricity market will have on estimated market power. They close with a discussion of the policy implications of the results.

Experimental power reactor dc generator energy storage study  

DOE Green Energy (OSTI)

This study covers the use of dc generators for meeting the Experimental Power Reactor Ohmic Heating Energy Storage Requirements. The dc generators satisfy these requirements which are the same as defined in WFPS-TME-038 which covered the use of ac generators and homopolar generators. The costs of the latter two systems have been revised to eliminate first-of-a-kind factors. The cost figures for dc generators indicate a need to develop larger machines in order to take advantage of the economy-of-scale that the large ac machines have. Each of the systems has its own favorable salient features on which to base a system selection.

Fourth National Green Power Marketing Conference Fourth National Green Power Marketing Conference Key Ingredients for Successful Markets Held May 10-11, 1999 in Philadelphia, Pennsylvania The Fourth National Green Power Marketing Conference was organized to examine the current state of green-power marketing and to explore opportunities to improve on the success of green-power sales in both regulated and deregulated markets. The conference was co-sponsored by the U.S. Department of Energy, Electric Power Research Institute, Renewable Energy Alliance, and Edison Electric Institute. View all of the Conference Presentations in Microsoft PowerPoint 95 (PPT) or Adobe Acrobat PDF format. Format is noted with file sizes. REPORT SUMMARY Today, in regulated monopoly markets, more than 50 utilities offer "green pricing" to their customers, but competitive green power marketing is still in early evolution. After a year of competitive market activity, it has become clear that the rules and mechanisms established for electric industry restructuring are critical to the success of green power marketing. The Fourth National Green Power Conference examined the current state of green power marketing, identified key market and policy needs under electric industry restructuring, and explored opportunities to improve on the success of green power sales in both regulated and deregulated markets.

Diagnosing Market Power in California's Deregulated Wholesale Electricity Market  

E-Print Network (OSTI)

Effective competition in wholesale electricity markets is a necessary feature of a successful electricity supply industry restructuring. We examine the degree of competition in the California wholesale electricity market during the period June 1998 to September 1999 by comparing the market prices with estimates of the prices that would have resulted if owners of instate fossil fuel generating facilities behaved as price takers. We find that there were significant departures from competitive pricing and that these departures are most pronounced during the highest demand periods, which tend to occur during the months of July through September. Through most of the winter and spring of 1999 there was little evidence of the exercise of market power. We find a significantly lower amount of market power exercised during summer 1999 than for the same months in summer 1998. Overall, the exercise of market power raised the cost of power purchases by about 16% above the competitive level. Following the p...

A high-power switch-mode dc power supply for dynamic loads  

SciTech Connect

High-voltage dc power supplies are often required to operate with highly dynamic loads, such as arcs. A switch-mode dc power supply can offer significant advantages over conventional thyristor-based dc power supplies under such conditions. It can quickly turn off the supply to extinguish the arc, and it can quickly recover after the arc. It has a relatively small output filter capacitance, which results in small stored energy available to the arc. A 400-kW, 50-kV switch-mode dc power supply for an electron-beam gun that exploits these advantages was designed and tested. It uses four 100-kW, current-source-type dc-dc converters with inputs in parallel and outputs in series. The dc-dc converters operate at 20 kHz in the voltage regulator part and 10 kHz in the inverter, transformer, and output rectifier part of the circuit. Insulated gate bipolar transistors (IGBTs) are used as the power switches. Special techniques are used to protect the power supply and load against arcs and hard shorts. The power supply has an efficiency of 93%, an output voltage ripple of 1%, and fast dynamic response. In addition, it is nearly one-third the size of conventional power supplies.

As the interface between fuel cells and the utility line, a self-commutated inverter is preferred to a line-commutated inverter because of its easy controllability. Using the gate turn off (GTO) thyristors, this inverter can have high efficiency and simple circuit configurations. This paper describes the design features and test results of the dc-to-ac power converter, which is principally composed of four-phase transistor chopper and 12-pulse GTO inverter, for a 50kW experimental fuel cell power system. Furthermore, new GTO inverter which improves the circuit efficiency is presented. Special emphasis is placed on a detailed analysis and evaluation of this GTO inverter.

A Multiphase, Modular, Bidirectional, Triple-Voltage DC-DC Converter Power Systems  

Science Conference Proceedings (OSTI)

Electrical power systems in future hybrid and fuel cell vehicles may employ three voltage [14 V, 42 V, and high voltage (HV)] nets. These will be necessary to accommodate existing 14-V loads as well as efficiently handle new heavy loads at the 42-V net and a traction drive on the HV bus. A low-cost DC-DC converter was proposed for connecting the three voltage nets. It minimizes the number of switches and their associated gate driver components by using two half-bridges and a high-frequency transformer. Another salient feature is that the half bridge on the 42-V bus is also utilized to provide the 14-V bus by operating at duty ratios around an atypical value of 1/3. Moreover, it makes use of the parasitic capacitance of the switches and the transformer leakage inductance for soft switching. The use of half bridges makes the topology well suited for interleaved multiphase modular configurations as a means to increase the power level because the capacitor legs can be shared. This paper presents simulation and experimental results on an interleaved two-phase arrangement rated at 4.5 kW. Also discussed are the benefits of operating with an atypical duty ratio on the transformer and a preferred multiphase configuration to minimize capacitor ripple currents.

Multi-port DC-DC Power Converter for Renewable Energy Application  

E-Print Network (OSTI)

In recent years, there has been lots of emphasis put on the development of renewable energy. While considerable improvement on renewable energy has been made, there are some inherent limitations for these renewable energies. For example, for solar and wind power, there is an intermittent nature. For the fuel cell, the dynamics of electro-chemical reaction is quite slow compared to the electric load. This will not be acceptable for modern electric application, which requires constant voltage of constant frequency. This work proposed and evaluated a new power circuit that can deal with the problem of the intermittent nature and slow response of the renewable energy. The proposed circuit integrates different renewable energy sources as well as energy storage. By integrating renewable energy sources with statistical tendency to compensate each other, the effect of the intermittent nature can be greatly reduced. This integration will increase the reliability and utilization of the overall system. Moreover, the integration of energy storage solves the problem of the slow response of renewable energy. It can provide the extra energy required by load or absorb the excessive energy provided by the energy sources, greatly improving the dynamics of overall system. To better understand the proposed circuit, "Dual Active Bridge" and "Triple Active Bridge" were reviewed first. The operation principles and the modeling were presented. Analysis and design of the overall system were discussed. Controller design and stability issues were investigated. Furthermore, the function of the central controller was explained. In the end, different simulations were made and discussed. Results from the simulations showed that the proposed multi-port DC-DC power converter had satisfactory performance under different scenarios encountered in practical renewable energy application. The proposed circuit is an effective solution to the problem due to the intermittent nature and slow response of the renewable energy.

Voluntary Green Power Market Forecast through 2015  

SciTech Connect

Various factors influence the development of the voluntary 'green' power market--the market in which consumers purchase or produce power from non-polluting, renewable energy sources. These factors include climate policies, renewable portfolio standards (RPS), renewable energy prices, consumers' interest in purchasing green power, and utilities' interest in promoting existing programs and in offering new green options. This report presents estimates of voluntary market demand for green power through 2015 that were made using historical data and three scenarios: low-growth, high-growth, and negative-policy impacts. The resulting forecast projects the total voluntary demand for renewable energy in 2015 to range from 63 million MWh annually in the low case scenario to 157 million MWh annually in the high case scenario, representing an approximately 2.5-fold difference. The negative-policy impacts scenario reflects a market size of 24 million MWh. Several key uncertainties affect the results of this forecast, including uncertainties related to growth assumptions, the impacts that policy may have on the market, the price and competitiveness of renewable generation, and the level of interest that utilities have in offering and promoting green power products.

Performance Evaluation of a Multi-Port DC-DC Current Source Converter for High Power Applications  

E-Print Network (OSTI)

With the ever-growing developments of sustainable energy sources such as fuel cells, photovoltaics, and other distributed generation, the need for a reliable power conversion system that interfaces these sources is in great demand. In order to provide the highest degree of flexibility in a truly distributed network, it is desired to not only interface multiple sources, but to also interface multiple loads. Modern multi-port converters use high frequency transformers to deliver the different power levels, which add to the size and complexity of the system. The different topological variations of the proposed multi-port dc-dc converter have the potential to solve these problems. This thesis proposes a unique dc-dc current source converter for multi-port power conversion. The presented work will explain the proposed multi-port dc-dc converter's operating characteristics, control algorithms, design and a proof of application. The converter will be evaluated to determine its functionality and applicability. Also, it will be shown that our converter has advantages over modern multi-port converters in its ease of scalability from kW to MW, low cost, high power density and adaption to countless combinations of multiple sources. Finally we will present modeling and simulation of the proposed converter using the PSIM software. This research will show that this new converter topology is unstable without feedback control. If the operating point is moved, one of the source ports of the multiport converter becomes unstable and dies off supplying very little or no power to the load while the remaining source port supplies all of the power the load demands. In order to prevent this and add stability to the converter a simple yet unique control method was implemented. This control method allowed for the load power demanded to be shared between the two sources as well as regulate the load voltage about its desired value.

Structural Features that Contribute to Market Power  

E-Print Network (OSTI)

In this paper we report an experiment that examines a primary concern of policy makers: how a structural feature of electric power networks can contribute to the exercise of market power by well-positioned players in deregulated markets. One such feature is the distribution of ownership of a given set of generating assets. For example, two large firms could be allocated baseload and intermediate generators such that either firm would be willing to withhold unilaterally the capacity of its intermediate generators from the market, to benefit from the supra-competitive prices which would result from only selling its baseload units. Conversely, ownership of the some of the intermediate generators from each of these firms could be transferred to two other firms, so that no one firm can unilaterally restrict output to spawn supra-competitive prices.

DC switching regulated power supply for driving an inductive load  

DOE Patents (OSTI)

A power supply for driving an inductive load current from a dc power supply hrough a regulator circuit including a bridge arrangement of diodes and switching transistors controlled by a servo controller which regulates switching in response to the load current to maintain a selected load current. First and second opposite legs of the bridge are formed by first and second parallel-connected transistor arrays, respectively, while the third and fourth legs of the bridge are formed by appropriately connected first and second parallel connected diode arrays, respectively. The regulator may be operated in three "stages" or modes: (1) For current runup in the load, both first and second transistor switch arrays are turned "on" and current is supplied to the load through both transistor arrays. (2) When load current reaches the desired level, the first switch is turned "off", and load current "flywheels" through the second switch array and the fourth leg diode array connecting the second switch array in series with the load. Current is maintained by alternating between modes 1 and 2 at a suitable duty cycle and switching rate set by the controller. (3) Rapid current rundown is accomplished by turning both switch arrays "off", allowing load current to be dumped back into the source through the third and fourth diode arrays connecting the source in series opposition with the load to recover energy from the inductive load. The three operating states are controlled automatically by the controller.

Environmental Assessment for power marketing policy for Southwestern Power Administration  

Science Conference Proceedings (OSTI)

Southwestern Power Administration (Southwestern) needs to renew expiring power sales contracts with new term (10 year) sales contracts. The existing contracts have been in place for several years and many will expire over the next ten years. Southwestern completed an Environmental Assessment on the existing power allocation in June, 1979 (a copy of the EA is attached), and there are no proposed additions of any major new generation resources, service to discrete major new loads, or major changes in operating parameters, beyond those included in the existing power allocation. Impacts from a no action plan, proposed alternative, and market power for less than 10 years are described.

Market power analysis in the EEX electricity market : an agent-based simulation approach.  

Science Conference Proceedings (OSTI)

In this paper, an agent-based modeling and simulation (ABMS) approach is used to model the German wholesale electricity market. The spot market prices in the European Energy Exchange (EEX) are studied as the wholesale market prices. Each participant in the market is modeled as an individual rationality-bounded agent whose objective is to maximize its own profit. By simulating the market clearing process, the interaction among agents is captured. The market clearing price formed by agentspsila production cost bidding is regarded as the reference marginal cost. The gap between the marginal cost and the real market price is measured as an indicator of possible market power exertion. Various bidding strategies such as physical withholding and economic withholding can be simulated to represent strategic bidding behaviors of the market participants. The preliminary simulation results show that some generation companies (GenCos) are in the position of exerting market power by strategic bidding.

Selling green power in California: Product, industry, and market trends  

SciTech Connect

As one of the first US stages to open its doors to retail electric competition, California offers an important opportunity to assess the effectiveness of green power marketing as a mechanism for supporting renewable energy. This report is an interim assessment of key green power product, industry, and market trends in California. The report identifies and analyzes: the potential size of the green power market in California; the companies participating in the green power market; the green power products being offered and their prices; the impact of the green market on renewable generators and the environment; and the influence of several public policies and non-governmental programs on the market for green power. Data used in this paper have been collected, in large part, from surveys and interviews with green power marketers that took place between December 1997 and April 1998. There remain legitimate concerns over the viability of green power marketing to support significant quantities of renewable energy and provide large environmental gains, and it is far too early to assess the overall strength of customer demand for renewable energy. A critical finding of this report is that, because of the high cost of acquiring and servicing residential customers and the low utility default service price, green power marketing affords new energy service providers one of the only viable entrees to California`s residential marketplace.

Integrated Solar Power Converters: Wafer-Level Sub-Module Integrated DC/DC Converter  

Science Conference Proceedings (OSTI)

Solar ADEPT Project: CU-Boulder is developing advanced power conversion components that can be integrated into individual solar panels to improve energy yields. The solar energy that is absorbed and collected by a solar panel is converted into useable energy for the grid through an electronic component called an inverter. Many large, conventional solar energy systems use one, central inverter to convert energy. CU-Boulder is integrating smaller, microinverters into individual solar panels to improve the efficiency of energy collection. The University’s microinverters rely on electrical components that direct energy at high speeds and ensure that minimal energy is lost during the conversion process—improving the overall efficiency of the power conversion process. CU-Boulder is designing its power conversion devices for use on any type of solar panel.

Status of the U.S. Market for Green Power  

NLE Websites -- All DOE Office Websites (Extended Search)

the the U.S. Market for Green Power Glenn Reed, XENERGY Inc. Ashley H. Houston, XENERGY Inc. ABSTRACT The advent of electric utility deregulation has created a market for green power; electricity generated in whole or in part from renewable resources. Green power satisfies both the environmental yearnings of its purchasers and the need of its sellers to differentiate their product offerings. While green power has captured a significant percentage of those residential and small commercial customers that have left their host utility, the percentage of all eligible customers in competitive markets that have chosen green power is still very small. This paper examines the development of competitive markets for green power in four states that have deregulated their electric utilities - California, Pennsylvania, New Jersey, and Massachusetts. The attributes of each of these state markets

Bang-bang-type optimal constant current control of parallel ac-dc power transmission systems  

SciTech Connect

The transient stability of an ac-dc hybrid system can be improved greatly by controlling the power flow of the dc transmission line. In this study the optimal changeover curve of dc current setting value on the phase plane with a quadratic curve are approximated. The coefficients of this curve are calculated in advance taking into account the loading condition of the power system and hence the proposed control scheme can be used for emergency control of the power system. The main conclusions from this study were that: to facilitate transient stability analysis, the dc transmission line is represented by equivalent load admittances, which vary every second with the operating condition of the transmission line; the action of the speed governor increases the damping coefficient of the power system and reduces the control time which means that the admissible range of the dc current setting value can be reduced by increasing the governor gain; and the optimal change-over curve of the dc current setting value is approximated by a quadratic curve, whose coefficients can be calculated in advance taking into account the loading condition of the power system. The suboptimal changeover curve thus obtained makes it possible to change the setting value of dc current without time delay in emergency condition. While the case of three-phase short-circuit fault was specifically discussed, it is possible to extend the results obtained to the case of successful or unsuccessful reclosing. The proposed method could also be applied to multimachine systems by using equivalent network reduction methods.

The role of public policy in emerging green power markets: An analysis of marketer preferences  

SciTech Connect

Green power marketing has been heralded by some as a means to create a private market for renewable energy that is driven by customer demand for green products. This report challenges the premise--sometimes proffered in debates over green markets--that profitable, sizable, credible markets for green products will evolve naturally without supportive public policies. Relying primarily on surveys and interviews of US green power marketers, the article examines the role of specific regulatory and legislative policies in enabling the green market, and searches for those policies that are believed by marketers to be the most conducive or detrimental to the expansion of the green market. The authors find that marketers: (1) believe that profitable green power markets will only develop if a solid foundation of supportive policies exists; (2) believe that establishing overall price competition and encouraging customer switching are the top priorities; (3) are somewhat leery of government-sponsored or mandated public information programs; and (4) oppose three specific renewable energy policies that are frequently advocated by renewable energy enthusiasts, but that may have negative impacts on the green marketers' profitability. The stated preferences of green marketers shed light on ways to foster renewables by means of the green market. Because the interests of marketers do not coincide perfectly with those of society, however, the study also recognizes other normative perspectives and highlights policy tensions at the heart of current debates related to green markets. By examining these conflicts, they identify three key policy questions that should direct future research: (1) to what extent should price competition and customer switching be encouraged at the expense of cost shifting; (2) what requirements should be imposed to ensure credibility in green products and marketing; and (3) how should the green power market and broader renewable energy policies interact?

PARABOLIC TROUGH SOLAR POWER FOR COMPETITIVE U.S. MARKETS  

E-Print Network (OSTI)

Nine parabolic trough power plants located in the California Mojave Desert represent the only commercial development of large-scale solar power plants to date. Although all nine plants continue to operate today, no new solar power plants have been completed since 1990. Over the last several years, the parabolic trough industry has focused much of its efforts on international market opportunities. Although the power market in developing countries appears to offer a number of opportunities for parabolic trough technologies due to high growth and the availability of special financial incentives for renewables, these markets are also plagued with many difficulties for developers. In recent years, there has been some renewed interest in the U.S. domestic power market as a result of an emerging green market and green pricing incentives. Unfortunately, many of these market opportunities and incentives focus on smaller, more modular technologies (such as photovoltaics or wind power), and as a result they tend to exclude or are of minimum long-term benefit to large-scale concentrating solar power technologies. This paper looks at what is necessary for large-scale parabolic trough solar power plants to compete with state-of-the-art fossil power technology in a competitive U.S. power market.

Implications of Carbon Regulation for Green Power Markets  

Science Conference Proceedings (OSTI)

This paper examines the potential effects that emerging mandatory carbon markets have for voluntary markets for renewable energy, or green power markets. In an era of carbon regulation, green power markets will continue to play an important role because many consumers may be interested in supporting renewable energy development beyond what is supported through mandates or other types of policy support. The paper examines the extent to which GHG benefits motivate consumers to make voluntary renewable energy purchases and summarizes key issues emerging as a result of these overlapping markets, such as the implications of carbon regulation for renewable energy marketing claims, the demand for and price of renewable energy certificates (RECs), and the use of RECs in multiple markets (disaggregation of attributes). It describes carbon regulation programs under development in the Northeast and California, and how these might affect renewable energy markets in these regions, as well as the potential interaction between voluntary renewable energy markets and voluntary carbon markets, such as the Chicago Climate Exchange (CCX). It also briefly summarizes the experience in the European Union, where carbon is already regulated. Finally, the paper presents policy options for policymakers and regulators to consider in designing carbon policies to enable carbon markets and voluntary renewable energy markets to work together.

A Bidirectional, Triple-Voltage DC-DC Converter for Hybrid and Fuel Cell Vehicle Power Systems  

Science Conference Proceedings (OSTI)

Electrical power systems in future hybrid and fuel cell vehicles may employ three voltage (14V, 42V and high voltage (HV)) nets. These will be necessary to accommodate existing 14V loads as well as efficiently handle new heavy loads at the 42V net and an electrical traction drive on the HV bus. A low-cost bi-directional dc-dc converter was proposed in (10) for connecting the three voltage nets. The converter consists of two half-bridges and a high-frequency transformer; thus minimizing the number of switching devices and their associated gate driver components. One salient feature is that the half-bridge on the 42V bus is also utilized to provide the 14V bus by operating its duty ratio around an atypical value of 1/3. This eliminates the need for an additional 14V/42V converter. Moreover, it makes use of the parasitic capacitance of the switches and the transformer leakage inductance for soft-switching; no extra active switches or passive resonant components are required. The use of half-bridges makes the topology suitable for interleaved multi-phase configurations as a means to increase the power level because the capacitor legs can be shared. This paper presents simulation and experimental results on an interleaved two-phase arrangement rated at 4.5 kW. Also discussed are the benefits of operating with the atypical duty ratio on the transformer and a preferred multi-phase configuration to minimize capacitor ripple currents.

The effect of the transmission grid on market power  

SciTech Connect

If competition could extend without hindrance through the entire extent of an electrically connected power grid, the US would have just two electricity markets, each with a uniform price. These markets would be competitive indeed. Unfortunately, losses and congestion present barriers to competition and thereby provide the likelihood of significantly increased market power. This paper begins the analysis of congestion as it affects the physical extent of markets and thereby affects the degree of market power. This is new territory; very little has previously been written in this area. Although the theoretical developments reported here rely on complex economic analysis, and although the market behaviors described are extremely subtle, several broad generalizations relevant to policy analysis can be made. From these generalizations one major policy conclusion can be drawn: In an unregulated market it will be socially beneficial to build a grid that is more robust than what is optimal in a regulated environment. Unused capacity may be needed. For a line to support full competition it may need to have a capacity that is much greater than the flow that will take place on it under full competition. Markets do not have sharp boundaries. Even with only one line the two busses may be in different regions, the same region, or partially in each other`s region. Increasing capacity is more effective on a small line. If connecting two busses with a very strong line will reduce market power, then the first MW of connecting capacity will have the most impact and each additional MW will have less. A congested line will cut a market into two non-competing regions. In each region the generators will markup according to the elasticity of the demand in only their region. A generator may reduce output in order to congest a line and increase its market power.

Econophysical Dynamics of Market-Based Electric Power Distribution Systems  

E-Print Network (OSTI)

As energy markets begin clearing at sub-hourly rates, their interaction with load control systems becomes a potentially important consideration. A simple model for the control of thermal systems using market-based power distribution strategies is proposed, with particular attention to the behavior and dynamics of electric building loads and distribution-level power markets. Observations of dynamic behavior of simple numerical model are compared to that of an aggregate continuous model. The analytic solution of the continuous model suggests important deficiencies in each. The continuous model provides very valuable insights into how one might design such load control system and design the power markets they interact with. We also highlight important shortcomings of the continuous model which we believe must be addressed using discrete models.

Advanced control for power density maximization of the brushless DC generator  

E-Print Network (OSTI)

This dissertation proposes a novel control technique for power density maximization of the brushless DC (BLDC) generator which is a nonsinusoidal power supply system. In a generator of given rating, the weight and size of the system affect the fuel consumption directly, therefore power density is one of the most important issues in a stand-alone generator. Conventional rectification methods cannot achieve the maximum power possible because of a distorted or unsuitable current waveform. The optimal current waveform for maximizing power density and minimizing machine size and weight in a nonsinusoidal power supply system has been proposed theoretically and verified by simulation and experimental work. Also, various attributes of practical interest are analyzed and simulated to investigate the impact on real systems.

Market potential of IGCC for domestic power production  

SciTech Connect

Mitretek Systems and CONSOL Inc. have completed the first phase of a market potential study for Integrated Coal Gasification Combined Cycle (IGCC) domestic power production. The U. S. Department of Energy (DOE) funded this study. The objective of this study is to provide DOE with data to estimate the future domestic market potential of IGCC for electricity generation. Major drivers in this study are the state of technology development, feedstock costs, environmental control costs, demand growth, and dispatchability. This study examines IGCC potential for baseload power production in the Northeast U. S., an important market area by virtue of existing coal infrastructure and proximity to coal producing regions. IGCC market potential was examined for two levels of technology development as a function of natural gas price and carbon tax. This paper discusses the results of this study, including the levels of performance and cost necessary to insure competitiveness with natural gas combined cycle plants.

Stabilizing control of parallel AC-DC power transmission systems by approximate switching curve  

SciTech Connect

A method to improve the transient stability of bulk power transmission system is presented. The method stabilizes the control of parallel ac-dc transmission systems using an approximate switching curve. The optimal switching curve is approximated by a power series and the resulting switching curve is determined independent of type and duration of faults that occur to the system. In addition, coefficients of the switching curve can be calculated on a off-line basis which allows use of simple on-line algebraic calculations in emergency conditions.

The 100,000 amp dc power supply for a staged hadron collider superferric magnet  

SciTech Connect

A 1.5 volt 100,000 amp DC switcher power supply was developed for testing a superferric magnet string at FNAL. This supply was used during testing as both the ramping supply and holding supply powering a single magnet load with a total load resistance of 0.7{micro} Ohms. The supply consists of ten paralleled switcher cells, powered by a 400 volt/600 Amp DC power supply. Each cell consists of an IGBT H-bridge driving a step-down transformer at a switching frequency of 2 kHz. The transformer has an effective turns ratio of 224:1. The secondary consists of 32 parallel single-turn full wave rectifier windings. The rectification is done with 64 Shottky diodes. Each cell is rated at 1.5 volts/10,000 amps. During this test each cell was operated as a constant power source without load current or field feedback. This paper will describe the design of the switcher cell and control system used during testing. We will also describe the next level of improvements to the current feedback system to improve the ramp control.

Experimental Tests of Competitive Markets for Electric Power  

E-Print Network (OSTI)

Testing the performance of electricity markets using POWERWEB has already shown that relatively inexperienced players can identify and exploit market power in load pockets. When transmission constraints are not binding, however, auctions with six players have been shown to be efficient. There is evidence from operating electricity markets that prices can be driven above competitive levels when the largest supplier controls less than 20 % of total installed capacity. This is accomplished by causing price spikes to occur. In experiments, uncertainty about the actual load and paying standby costs regardless of whether or not a unit is actually dispatched contribute to volatile price behavior. The objective of this paper is to investigate characteristics of a market that affect price volatility. The tests consider three different sets of rules for setting price when there are capacity shortfalls, and the following four market structures: 1. Load is responsive to price 2. Price forecasts are made before market settlement 3 A day-ahead market and a balancing market auction 4. Suppliers are paid actual offers (a discriminatory auction) 1

Speculative Trading and Market Performance: The Effect of Arbitrageurs on Efficiency and Market Power in the New York Electricity Market  

E-Print Network (OSTI)

While the effect speculators have on forward premiums (the difference between forward and expected spot prices) has been widely studied, there has been very little focus on the effect speculators have on competition in the product market. I study the effect speculators have had on production decisions and price levels in New York’s deregulated electricity market. For the first two years of its operation, the market, which opened in November 1999, restricted trade to producers and retailers of electricity. During this period, the forward price of electricity in western New York was significantly higher than the expected spot price. I show that, after the market opened to purely speculative traders, the forward premium significantly decreased. In addition, the forward price of transmission (the price difference between two geographically distinct points) ceased to differ significantly from the expected spot price of transmission. I present a theoretical model to help understand these price relationships and other possible effects of speculators on market prices and firms’ production decisions. Absent speculators, the model predicts that firms with market power will price discriminate between the forward and spot markets for electricity, resulting

Econophysics of adaptive power markets: When a market does not dampen fluctuations but amplifies them  

E-Print Network (OSTI)

The average economic agent is often used to model the dynamics of simple markets, based on the assumption that the dynamics of many agents can be averaged over in time and space. A popular idea that is based on this seemingly intuitive notion is to dampen electric power fluctuations from fluctuating sources (as e.g. wind or solar) via a market mechanism, namely by variable power prices that adapt demand to supply. The standard model of an average economic agent predicts that fluctuations are reduced by such an adaptive pricing mechanism. However, the underlying assumption that the actions of all agents average out on the time axis is not always true in a market of many agents. We numerically study an econophysics agent model of an adaptive power market that does not assume averaging a priori. We find that when agents are exposed to source noise via correlated price fluctuations (as adaptive pricing schemes suggest), the market may amplify those fluctuations. In particular, small price changes may translate to...

ac/dc power converter for batteries and fuel cells. Annual report  

SciTech Connect

The overall objective of the EPRI RP841-1 program is the design of an advanced power converter for use in both battery energy storage and fuel cell generation systems in the 1980's. This goal will be accomplished by expansion of United's existing FCG-1 fuel cell power conditioning inverter into a high-efficiency inverter--rectifier system employing improved commutation circuits and advanced (1980's) semiconductor devices capable of operating over wider dc voltage ranges. A separate but concurrent program for the U.S. Department of Energy (DOE) -- E(49-18)2122 -- is examining augmentation of the present FCG-1 inverter for operation as an inverter--rectifier with battery systems; feasibility and operating characteristics have been demonstrated. United's activities and accomplishments in the EPRI RP841-1 program include revision of the preliminary specification for ac/dc conversion equipment contained in the Statement of Work, survey of seven semiconductor manufacturers to project characteristics of 1980's thyristors, screening of fifteen commutation concepts and selection of the two most promising options for experimental evaluation, and modifications of existing experimental power pole hardware to evaluate the selected advanced commutation circuits. 34 figures, 3 tables.

Organization of bulk power markets: A concept paper  

SciTech Connect

The electricity industry in the US today is at a crossroads. The restructuring debate going on in most regions has made it clear that the traditional model of vertically integrated firms serving defined franchise areas and regulated by state commissions may not be the pattern for the future. The demands of large customers seeking direct access to power markets, the entry of new participants, and proposed reforms of the regulatory process all signify a momentum for fundamental change in the organization of the industry. This paper addresses electricity restructuring from the perspective of bulk power markets. The authors focus attention on the organization of electricity trade and the various ways it has been and might be conducted. Their approach concentrates on conceptual models and empirical case studies, not on specific proposals made by particular utilities or commissions. They review literature in economics and power system engineering that is relevant to the major questions. The objective is to provide conceptual background to industry participants, e.g. utility staff, regulatory staff, new entrants, who are working on specific proposals. While they formulate many questions, they do not provide definitive answers on most issues. They attempt to put the industry restructuring dialogue in a neutral setting, translating the language of economists for engineers and vice versa. Towards this end they begin with a review of the basic economic institutions in the US bulk power markets and a summary of the engineering practices that dominate trade today.

First DOE/EPRI Green Pricing Workshop First DOE/EPRI Green Pricing Workshop April 11-12, 1996 Golden, Colorado Prepared by Blair G. Swezey, National Renewable Energy Laboratory Terry M. Peterson, Electric Power Research Institute I. Overview Green pricing is an evolving utility service that responds to utility customers' preferences for electricity derived from renewable energy sources such as solar, wind, or biomass. Under green pricing, utilities offer customers a voluntary program or service to support electricity generated from renewable energy systems. Customers are asked to pay a rate premium, which is meant to cover the costs that the utility incurs above those paid today for electricity from conventional fuels. Utilities are considering green pricing as a way to build customer loyalty, deploy popular renewable technologies, expand business lines and expertise, and improve understanding of customer response to unbundled pricing and services.

POINT OF COLLAPSE METHODS APPLIED TO AC/DC POWER SYSTEMS  

E-Print Network (OSTI)

This paper describes an extension of the Point of Collapse method developed for ac systems studies to the determination of saddle-node bifurcations in power systems including high voltage direct current (HVDC) transmission. Bus voltage profiles are illustrated for an ac/dc test system, which significantly differ from the profiles of pure ac systems for typical system models. In particular, voltage dependent current order limits (VD-COLs) are shown to affect the voltage profiles ("nose" curves) and the loadability margin of the system. It is also shown that Hopf bifurcations, which are not possible in purely ac lossless systems with second-order generator models, become plausible when the dynamics for the HVDC system are included.

Extended Constant Power Speed Range of the Brushless DC Motor Through Dual Mode Inverter Control  

SciTech Connect

The trapezoidal back electromotive force (emf) brushless direct current (dc) motor (BDCM) with surface-mounted magnets has high-power density and efficiency especially when rare-earth magnet materials are used. Traction applications, such as electric vehicles, could benefit significantly from the use of such motors. Unfortunately, a practical means for driving the motor over a constant power speed ratio (CPSR) of 5:1 or more has not yet been developed. A key feature of these motors is that they have low internal inductance. The phase advance method is effective in controlling the motor power over such a speed range, but the current at high speed may be several times greater than that required at the base speed. The increase in current during high-speed operation is due to the low motor inductance and the action of the bypass diodes of the inverter. The use of such a control would require increased current rating of the inverter semiconductors and additional cooling for the inverter, where the conduction losses increase proportionally with current, and especially for the motor, where the losses increase with the square of the current. The high current problems of phase advance can be mitigated by adding series inductance; however, this reduces power density, requires significant increase in supply voltage, and leaves the CPSR performance of the system highly sensitive to variations in the available voltage. A new inverter topology and control scheme has been developed that can drive low-inductance BDCMs over the CPSR that would be required in electric vehicle applications. This new controller is called the dual-mode inverter control (DMIC). It is shown that the BDCM has an infinite CPSR when it is driven by the DMIC.

Factors affecting potential market penetration of laser fusion power plants  

SciTech Connect

A mini-model has been constructed to estimate the optimal size of laser fusion power plants and to estimate the allowable cost of the first such plant in relation to the next best alternative. In estimating the costs of laser fusion, the mini-model incorporates such factors as market penetration, learning, economies of scale, system size, transmission costs, reserve requirements, development and licensing costs and site costs. The results of the mini-model simulations indicate that the optimal laser fusion plant size is approximately 3 GWe; risk considerations unincorporated in the mini-model suggest an optimal size closer to 2.5 GWe.

Phantom Power: The Status of Fuel Cell Technology Markets  

E-Print Network (OSTI)

Fuel cells have been touted as one of the most reliable and environmentally sound methods of producing high-quality electricity for use in the industrial sector. Fuel cell developers are racing to produce larger quantities of fuel cells at lower prices. While the power densities of fuel-cell stacks have been increasing, fuel cell technologies have unfortunately remained uneconomical for the majority of industrial customers. The growth of the fuel cell market has not increased at the rate at which developers and marketers would like us to believe. With stricter federal air regulations coming into effect in 2007 and more urban/industrial areas falling into non-attainment for pollutants such as NOx operators of distributed generation systems may begin to consider fuel cells a more viable option. In this paper we will explore the potential of various fuel cell technologies for providing on-site generation at industrial facilities. Our analysis will include brief technical descriptions of the various fuel cell technologies as well as a description of applicable end-use applications for the various technologies. We will determine which technologies hold the most potential for providing reliable power and heat for processes as well as estimates of technically and economically feasible industrial fuel cell capacity between now and 2020. The manufacturing service infrastructure, technical and market barriers to increased demand, and regulatory, permitting, and siting issues will be explored. We will outline the various factors that play in the technical and economic diffusion and offer sample diffusion curves for the various fuel cell technologies.

E-Print Network (OSTI)

The paper surveys the literature and publicly available information on market power monitoring in electricity wholesale markets. After briefly reviewing definitions, strategies and methods of mitigating market power we examine the various methods of detecting market power that have been employed by academics and market monitors/regulators. These techniques include structural and behavioural indices and analysis as well as various simulation approaches. The applications of these tools range from spot market mitigation and congestion management through to long-term market design assessment and merger decisions. Various market-power monitoring units already track market behaviour and produce indices. Our survey shows that these units collect a large amount of data from various market participants and we identify the crucial role of the transmission system operators with their access to dispatch and system information. Easily accessible and comprehensive data supports effective market power monitoring and facilitates market design evaluation. The discretion required for effective market monitoring is facilitated by institutional independence.

Scenario Generation for Price Forecasting in Restructured Wholesale Power Markets  

E-Print Network (OSTI)

In current restructured wholesale power markets, the short length of time series for prices makes it difficult to use empirical price data to test existing price forecasting tools and to develop new price forecasting tools. This study therefore proposes a two-stage approach for generating simulated price scenarios based on the available price data. The first stage consists of an Autoregressive Moving Average (ARMA) model for determining scenarios of cleared demands and scheduled generator outages (D&O), and a moment-matching method for reducing the number of D&O scenarios to a practical scale. In the second stage, polynomials are fitted between D&O and wholesale power prices in order to obtain price scenarios for a specified time frame. Time series data from the Midwest ISO (MISO) are used as a test system to validate the proposed approach. The simulation results indicate that the proposed approach is able to generate price scenarios for distinct seasons with empirically realistic characteristics.

A Stabilization of Frequency Oscillations in a Parallel AC-DC Interconnected Power System via an HVDC Link  

E-Print Network (OSTI)

This paper presents a new application of High Voltage Direct Current (HVDC) link to stabilization of frequency oscillations in a parallel AC-DC interconnected power system. When an interconnected AC power system is subjected to a large load with rapid change, system frequency may be considerably disturbed and becomes oscillatory. By utilizing the system interconnections as the control channels of HVDC link, the tie-line power modulation of HVDC link through interconnections is applicable for stabilizing the frequency oscillations of AC systems. In the design of power modulation controller, the technique of overlapping decompositions and the eigenvalue assignment are applied to establish the state feedback control scheme. To evaluate control effects, a linearized model of a parallel AC-DC interconnected system, including a power modulation controller of HVDC link, is investigated by simulation study. Simulation results show that the proposed controller is not only effective in damping out frequency oscillations, but also capable of alleviating the transient frequency swing caused by a large load disturbance.

Effective Ancillary Services Market Designs on High Wind Power Penetration Systems: Preprint  

DOE Green Energy (OSTI)

This paper focuses on how the ancillary service market designs are implemented and how they may require changes on systems with greater penetrations of variable renewable energy suppliers, in particular wind power. Ancillary services markets have been developed in many of the restructured power system regions throughout the world. Ancillary services include the services that support the provision of energy to support power system reliability. The ancillary services markets are tied tightly to the design of the energy market and to the physics of the system and therefore careful consideration of power system economics and engineering must be considered in their design. This paper focuses on how the ancillary service market designs are implemented and how they may require changes on systems with greater penetrations of variable renewable energy suppliers, in particular wind power.

Bonneville Power Administration`s Commercial Sector Conservation Market.  

SciTech Connect

Bonneville has, as part of its resource plan, accepted targets for commercial conservation which are quite ambitious. To meet these targets, Bonneville will need to acquire as much cost-effective conservation as possible over the next twelve years. With this in mind, this document explores the relative importance of different commercial market segments and the types of assistance each market needs to install as many cost-effective conservation measures in as many buildings as possible. This document reviews Bonneville`s marketing environment and position, and suggests goals for commercial sector conservation marketing at Bonneville. Then it presents a broad market segmentation and series of additional demographic analyses. These analyses assess what groups of consumers Bonneville must reach to achieve most of the commercial conservation potential and what is needed to reach them. A final section reviews the success of Bonneville programs at reaching various markets. The market segmentation identifies different types of consumers and opportunities which would require distinct program approaches. Four large market segments are identified that have distinct program needs. Then four ``building life-cycle events`` are identified which provide important conservation opportunities and also require distinct program services. This creates a matrix of 16 cells which delineate distinct needs for program marketing. Each of the four key market segments manages at least 20% of the Region`s commercial floorspace.

Green Power Marketing in the United States: A Status Report (2008 Data)  

Science Conference Proceedings (OSTI)

Voluntary consumer decisions to buy electricity supplied from renewable energy sources represent a powerful market support mechanism for renewable energy development. In the early 1990s, a small number of U.S. utilities began offering 'green power' options to their customers. Since then, these products have become more prevalent, both from traditional utilities and from renewable energy marketers operating in states that have introduced competition into their retail electricity markets or offering renewable energy certificates (RECs) online. Today, more than half of all U.S. electricity customers have an option to purchase some type of green power product directly from a retail electricity provider, while all consumers have the option to purchase RECs. This report documents green power marketing activities and trends in the United States including utility green pricing programs offered in regulated electricity markets; green power marketing activity in competitive electricity markets, as well as green power sold to voluntary purchasers in the form of RECs; and renewable energy sold as greenhouse gas offsets in the United States. These sections are followed by a discussion of key market trends and issues. The final section offers conclusions and observations.

NLE Websites -- All DOE Office Websites (Extended Search)

Customer Customer Choice and Green Power Marketing: A Critical Review and Analysis of Experience to Date Ryan Wiser, Lawrence Berkeley National Laboratory Mark Bolinger, Lawrence Berkeley National Laboratory Edward Holt, Ed Holt & Associates, Inc. ABSTRACT This article explores whether and to what extent individuals are willing to voluntarily pay a premium for products that provide public environmental benefits. In particular, we critically review and analyze the status and impacts of U.S. green power marketing to date. Green power marketing-the business of selling electricity products distinguished by their environmental attributes-seeks to develop a private market for renewable energy driven by consumer demand for green products. Debate has centered on the ability of such a market to provide a significant level of support for renewable energy sources. This paper examines

International and Domestic Market Opportunities for Biomass Power: Volumes I and II  

DOE Green Energy (OSTI)

This report examines the domestic and international markets for biopower. Domestic and foreign markets present fundamentally different challenges to private power developers. Volume I focuses on the domestic market for biopower. The domestic challenge lies in finding economically viable opportunities for biopower. Vol. I outlines the current state of the U.S. biomass industry, discusses policies affecting biomass development, describes some demonstration projects currently underway, and discusses the future direction of the industry. Volume II focuses on the international market for biopower. Recent literature states that the electricity investment and policy climate in foreign markets are the key elements in successful private project development. Vol. II discusses the financing issues, policy climate, and business incentives and barriers to biopower development. As India and China are the largest future markets for biopower, they are the focus of this volume. Three other top markets- -Brazil, Indonesia, and the Philippines--are also discussed. Potential financial resources wrap up the discussion.

Determining market power in deregulated generation markets by measuring price-cost margins  

Science Conference Proceedings (OSTI)

In this article. the author considers one of the more prominent examples of the SFE type by Aleksandr Rudkevich, Max Duckworth, and Richard Rosen (RDR). The conclusion of their paper, that fewer than 30 competitive firms (or, equivalently, an HHI over 333) likely constitute an impermissibly concentrated market, is a startling one, since it is unlikely that any deregulated electricity market will have this many competitors. In examining the source of the RDR conclusion in some detail and seeing where it goes awry, the author thinks it is possible to glean principles that can guide regulators to draw more sensible conclusions about the number of competitors required in these markets.

Green Power Marketing in the United States: A Status Report (Ninth Edition)  

SciTech Connect

Voluntary consumer decisions to purchase electricity supplied by renewable energy sources represent a powerful market support mechanism for renewable energy development. Beginning in the early 1990s, a small number of U.S. utilities began offering ''green power'' options to their customers. Since then, these products have become more prevalent, both from traditional utilities and from marketers operating in states that have introduced competition into their retail electricity markets. Today, more than half of all U.S. consumers have an option to purchase some type of green power product from a retail electricity provider. Currently, more than 600 utilities, or about 20% of utilities nationally, offer green power programs to customers. These programs allow customers to purchase some portion of their power supply as renewable energy--almost always at a higher price--or to contribute funds for the utility to invest in renewable energy development. The term ''green pricing'' is typically used to refer to these utility programs offered in regulated or noncompetitive electricity markets. This report documents green power marketing activities and trends in the United States.

Geothermal Power and Interconnection: The Economics of Getting to Market  

Science Conference Proceedings (OSTI)

This report provides a baseline description of the transmission issues affecting geothermal technologies. The report begins with a comprehensive overview of the grid, how it is planned, how it is used, and how it is paid for. The report then overlays onto this 'big picture' three types of geothermal technologies: conventional hydrothermal systems; emerging technologies such as enhanced engineered geothermal systems (EGS) and geopressured geothermal; and geothermal co-production with existing oil and gas wells. Each category of geothermal technology has its own set of interconnection issues, and these are examined separately for each. The report draws conclusions about each technology's market affinities as defined by factors related to transmission and distribution infrastructure. It finishes with an assessment of selected markets with known geothermal potential, identifying those that offer the best prospects for near-term commercial development and for demonstration projects.

DC CIRCUIT POWERED BY ORBITAL MOTION: MAGNETIC INTERACTIONS IN COMPACT OBJECT BINARIES AND EXOPLANETARY SYSTEMS  

Science Conference Proceedings (OSTI)

The unipolar induction DC circuit model, originally developed by Goldreich and Lynden-Bell for the Jupiter-Io system, has been applied to different types of binary systems in recent years. We show that there exists an upper limit to the magnetic interaction torque and energy dissipation rate in such a model. This arises because when the resistance of the circuit is too small, the large current flow severely twists the magnetic flux tube connecting the two binary components, leading to the breakdown of the circuit. Applying this limit, we find that in coalescing neutron star binaries, magnetic interactions produce negligible correction to the phase evolution of the gravitational waveform, even for magnetar-like field strengths. However, energy dissipation in the binary magnetosphere may still give rise to electromagnetic radiation prior to the final merger. For ultracompact white dwarf binaries, we find that unipolar induction does not provide adequate energy dissipation to explain the observed X-ray luminosities of several sources. For exoplanetary systems containing close-in Jupiters or super-Earths, the magnetic torque and energy dissipation induced by the orbital motion are negligible, except possibly during the early T Tauri phase, when the stellar magnetic field is stronger than 10{sup 3} G.

Wind Generation in the Future Competitive California Power Market  

DOE Green Energy (OSTI)

The goal of this work is to develop improved methods for assessing the viability of wind generation in competitive electricity markets. The viability of a limited number of possible wind sites is assessed using a geographic information system (GIS) to determine the cost of development, and Elfin, an electric utility production costing and capacity expansion model, to estimate the possible revenues and profits of wind farms at the sites. This approach improves on a simple profitability calculation by using a site-specific development cost calculation and by taking the effect of time varying market prices on revenues into account. The first component of the work is to develop data characterizing wind resources suitable for use in production costing and capacity expansion models, such as Elfin, that are capable of simulating competitive electricity markets. An improved representation of California wind resources is built, using information collected by the California Energy Commission (CE C) in previous site evaluations, and by using a GIS approach to estimating development costs at 36 specific sites. These sites, which have been identified as favorable for wind development, are placed on Digital Elevation Maps (DEMs) and development costs are calculated based on distances to roads and transmission lines. GIS is also used to develop the potential capacity at each site by making use of the physical characteristics of the terrain, such as ridge lengths. In the second part of the effort, using a previously developed algorithm for simulating competitive entry to the California electricity market, the Elfin model is used to gauge the viability of wind farms at the 36 sites. The results of this exercise are forecasts of profitable development levels at each site and the effects of these developments on the electricity system as a whole. Under best guess assumptions, including prohibition of new nuclear and coal capacity, moderate increase in gas prices and some decline in renewable capital costs, about 7.35 GW of the 10 GW potential capacity at the 36 specific sites is profitably developed and 62 TWh of electricity produced per annum by the year 2030. Most of the development happens during the earlier years of the forecast. Sensitivity of these results to future gas price scenarios is also presented. This study also demonstrates that an analysis based on a simple levelized profitability calculation approach does not sufficiently capture the implications of time varying prices in a competitive market.

Modeling hydro power plants in deregulated electricity markets : integration and application of EMCAS and VALORAGUA.  

Science Conference Proceedings (OSTI)

In this paper, we present details of integrating an agent-based model, Electricity Market Complex Adaptive System (EMCAS) with a hydro-thermal coordination model, VALORAGUA. EMCAS provides a framework for simulating deregulated markets with flexible regulatory structure along with bidding strategies for supply offers and demand bids. VALORAGUA provides longer-term operation plans by optimizing hydro and thermal power plant operation for the entire year. In addition, EMCAS uses the price forecasts and weekly hydro schedules from VALORAGUA to provide intra-week hydro plant optimization for hourly supply offers. The integrated model is then applied to the Iberian electricity market which includes about 111 thermal plants and 38 hydro power plants. We then analyze the impact of hydro plant supply offers on the market prices and ways to minimize the Gencospsila exposure to price risk.

New wholesale power market design using linked forward markets : a study for the DOE energy storage systems program.  

Science Conference Proceedings (OSTI)

This report proposes a reformulation of U.S. ISO/RTO-managed wholesale electric power mar- kets for improved reliability and e ciency of system operations. Current markets do not specify or compensate primary frequency response. They also unnecessarily limit the participation of new technologies in reserve markets and o er insu cient economic inducements for new capacity invest- ment. In the proposed market reformulation, energy products are represented as physically-covered rm contracts and reserve products as physically-covered call option contracts. Trading of these products is supported by a backbone of linked ISO/RTO-managed forward markets with planning horizons ranging from multiple years to minutes ahead. A principal advantage of this reformulation is that reserve needs can be speci ed in detail, and resources can o er the services for which they are best suited, without being forced to conform to rigid reserve product de nitions. This should improve the business case for electric energy storage and other emerging technologies to provide reserve. In addition, the facilitation of price discovery should help to ensure e cient energy/reserve procurement and adequate levels of new capacity investment.

2007 Wholesale Power Rate Case Final Proposal : Market Price Forecast Study.  

Science Conference Proceedings (OSTI)

This study presents BPA's market price forecasts for the Final Proposal, which are based on AURORA modeling. AURORA calculates the variable cost of the marginal resource in a competitively priced energy market. In competitive market pricing, the marginal cost of production is equivalent to the market-clearing price. Market-clearing prices are important factors for informing BPA's power rates. AURORA was used as the primary tool for (a) estimating the forward price for the IOU REP Settlement benefits calculation for fiscal years (FY) 2008 and 2009, (b) estimating the uncertainty surrounding DSI payments and IOU REP Settlements benefits, (c) informing the secondary revenue forecast and (d) providing a price input used for the risk analysis. For information about the calculation of the secondary revenues, uncertainty regarding the IOU REP Settlement benefits and DSI payment uncertainty, and the risk run, see Risk Analysis Study WP-07-FS-BPA-04.

In this paper we give an overview of the Electricity Market Complex Adaptive System (EMCAS) model. EMCAS uses the agent-based modeling and simulation (ABMS) technique to model the market participants in electricity markets as different agents with different strategies, risk preferences, and objectives. The complex operations of an electricity market can be simulated across several time horizons from day-ahead scheduling to long-term expansion planning. The methodology used in the model is discussed and a central European case is utilized to illustrate how EMCAS can be used to analyze a power system's operation under various assumptions. The results show the effectiveness of the model, and how the ABMS approach allows the testing of different market conditions.

Simona Lup, Jia Jing Liu and Stephen Sosnicki for help with running the experiments and testing the software. This paper has benefited from comments from Kevin McCabe, Mark Olson, Dave Porter, and Stan Reynolds, but all errors are our own. The data are available upon request from the authors. Controlling Market Power and Price Spikes in Electricity Networks: Demand-Side Bidding In this paper we report experiments that examine how two structural features of electricity networks contribute to the exercise of market power in deregulated markets. The first feature is the distribution of ownership of a given set of generating assets. In the market power treatment, two large firms are allocated baseload and intermediate cost generators such that either firm might unilaterally withhold the capacity of its intermediate cost generators from the market to benefit from the supracompetitive prices that would result from only selling its baseload units. In the converse treatment, ownership of some of the intermediate cost generators is transferred from each of these firms to two other firms, so that no one firm could unilaterally restrict output to spawn supra-competitive prices. The second feature explores how the presence of line constraints in a radial network may segment the market and promote supra-competitive pricing in the isolated market segments. We also consider the interaction effect when both of these structural features are present. Having established a wellcontrolled data set with price spikes paralleling those observed in the naturally occurring economy, we also extend the design to include demand-side bidding. We find that demand-side bidding completely neutralizes the exercise of market power and eliminates price spikes.

Photovoltaic power systems market identification and analysis. Final report, January 1977--February 1978  

DOE Green Energy (OSTI)

This report summarizes the work done by InterTechnology/Solar Corporation, its consultants, Mobil Tyco Solar Energy Corporation and the University of Delaware Institute for Energy Conversion, and its consultants, during the marketing analysis of near and intermediate term photovoltaic power applications. To obtain estimates of the domestic and foreign market potential for photovoltaically powered devices two approaches were used. First, the study was identifying then screening all possible photovoltaic power supply applications. This approach encompassed the first two tasks of the study: (1) a survey of the current uses of photovoltaic systems, both domestic and international, and a projection of the usage of those systems into the future; and (2) a new idea generation task which attempted to come up with new ways of using photovoltaic power. Second, the study required in-depth analysis of key near-term and intermediate-term photovoltaic applications identified during the first phase to obtain reasonable estimates of photovoltaic market potential. This process encompassed the third and fourth tasks of the analysis: (3) refinement of ideas generated in Task 2 so that certain products/applications could be identified, the product defined and a market survey carried out; and (4) development of a detailed product scenario which forecasts sales, barriers to market acceptance, and technical innovationsrequired for proper introduction of the products. The work performed and findings of each task are presented.

Markets to Facilitate Wind and Solar Energy Integration in the Bulk Power Supply: An IEA Task 25 Collaboration; Preprint  

Science Conference Proceedings (OSTI)

Wind and solar power will give rise to challenges in electricity markets regarding flexibility, capacity adequacy, and the participation of wind and solar generators to markets. Large amounts of wind power will have impacts on bulk power system markets and electricity prices. If the markets respond to increased wind power by increasing investments in low-capital, high-cost or marginal-cost power, the average price may remain in the same range. However, experiences so far from Denmark, Germany, Spain, and Ireland are such that the average market prices have decreased because of wind power. This reduction may result in additional revenue insufficiency, which may be corrected with a capacity market, yet capacity markets are difficult to design. However, the flexibility attributes of the capacity also need to be considered. Markets facilitating wind and solar integration will include possibilities for trading close to delivery (either by shorter gate closure times or intraday markets). Time steps chosen for markets can enable more flexibility to be assessed. Experience from 5- and 10-minute markets has been encouraging.

The European Emissions Trading Scheme (ETS) limits CO2 emissions from covered sectors, especially electricity until December 2007, after which a new set of Allowances will be issued. The paper demonstrates that the impact of controlling the quantity rather than the price of carbon is to reduce the elasticity of demand for gas, amplifying the market power of gas suppliers, and also amplifying the impact of gas price increases on the price of electricity. A rough estimate using just British data suggests that this could increase gas market power by 50%. Key words Climate change, emissions trading, market power, gas, quotas vs taxes JEL classification

Effects of Demand Response on Retail and Wholesale Power Markets  

Science Conference Proceedings (OSTI)

Demand response has grown to be a part of the repertoire of resources used by utilities to manage the balance between generation and load. In recent years, advances in communications and control technology have enabled utilities to consider continuously controlling demand response to meet generation, rather than the other way around. This paper discusses the economic applications of a general method for load resource analysis that parallels the approach used to analyze generation resources and uses the method to examine the results of the US Department of Energy’s Olympic Peninsula Demonstration Testbed. A market-based closed-loop system of controllable assets is discussed with necessary and sufficient conditions on system controllability, observability and stability derived.

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

DOE Green Energy (OSTI)

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.

Market definition study of photovoltaic power for remote villages in developing countries  

DOE Green Energy (OSTI)

The objective of this market definition study is to assess the market potential for the use of photovoltaic power systems for remote villages in developing countries. The approach used was to conduct an in-depth literature search followed by in-country surveys of selected developing countries in Africa, the Middle East, Southeast Asia, and Latin America. The purpose of these surveys was to determine the current energy situation in these countries, the level of rural electrification activity, their knowledge and interest in solar and specifically photovoltaics, their financial resource capability, and the probability of development of a market for photovoltaics based on these and other factors. Findings are presented. The conclusion reached by the survey is that there is a significant market potential for photovoltaics in village power applications in developing countries. Extrapolation of the number of unelectrified villages results in an estimated potential of as much as 20,000 MWp, a potential similar in magnitude to previous UN and World Bank estimates. Recommendations for market stimulation are presented. (WHK)

Low-voltage-swing Monolithic DC-DC Conversion  

E-Print Network (OSTI)

Abstract—A low-voltage-swing MOSFET gate drive technique is proposed in this paper for enhancing the efficiency characteristics of high-frequency-switching dc–dc converters. The parasitic power dissipation of a dc–dc converter is reduced by lowering the voltage swing of the power transistor gate drivers. A comprehensive circuit model of the parasitic impedances of a monolithic buck converter is presented. Closed-form expressions for the total power dissipation of a low-swing buck converter are proposed. The effect of reducing the MOSFET gate voltage swings is explored with the proposed circuit model. A range of design parameters is evaluated, permitting the development of a design space for full integration of active and passive devices of a low-swing buck converter on the same die, for a target CMOS technology. The optimum gate voltage swing of a power MOSFET that maximizes efficiency is lower than a standard full voltage swing. An efficiency of 88 % at a switching frequency of 102 MHz is achieved for a voltage conversion from 1.8 to 0.9 V with a low-swing dc–dc converter based on a 0.18- m CMOS technology. The power dissipation of a low-swing dc–dc converter is reduced by 27.9 % as compared to a standard full-swing dc–dc converter. Index Terms—Buck converter, dc–dc converters, enhanced efficiency, high frequency, low power, low swing, monolithic integration, on-chip voltage conversion, parameter optimization, parasitic impedances, power dissipation modeling, power supply, reduced energy dissipation, reduced voltage swing, switching voltage regulator.

We investigate the effect on the original equipment manufacturer and on consumers if the manufacturer is the only (monopoly) service provider for the equipment it sells. Controlling the service market may be a profitable strategic objective, but there are several possible problems. The firm needs a durable intellectual property advantage to dominate independent service organizations. Even with such an advantage, active competition from vendors of alternate original equipment may force the manufacturer to dissipate service profits through equipment market competition to obtain market share. Further, the courts appear to be sympathetic to antitrust claims against manufacturers when they attempt to extend their proprietary control over one component of service to monopoly control overall all service provision. We also find that reputation effects may prevent manufacturers from fully exploiting their monopoly power in the aftermarket, but that reputation does not generally lead to competitive prices.

Transition from Exponential to Power Law Distributions in a Chaotic Market  

E-Print Network (OSTI)

Economy is demanding new models, able to understand and predict the evolution of markets. To this respect, Econophysics offers models of markets as complex systems, that try to comprehend macro-, system-wide states of the economy from the interaction of many agents at micro-level. One of these models is the gas-like model for trading markets. This tries to predict money distributions in closed economies and quite simply, obtains the ones observed in real economies. However, it reveals technical hitches to explain the power law distribution, observed in individuals with high incomes. In this work, non linear dynamics is introduced in the gas-like model in way that an effort to overcome these flaws. A particular chaotic dynamics is used to break the pairing symmetry of agents $(i,j)\\Leftrightarrow(j,i)$. The results demonstrate that a "chaotic gas-like model" can reproduce the Exponential and Power law distributions observed in real economies. Moreover, it controls the transition between them. This may give some insight of the micro-level causes that originate unfair distributions of money in a global society. Ultimately, the chaotic model makes obvious the inherent instability of asymmetric scenarios, where sinks of wealth appear and doom the market to extreme inequality.

A utility survey and market assessment on repowering in the electric power industry  

SciTech Connect

Section 1 of this report provides a background about the DOE High Performance Power Systems (HIPPS) program. There are two kinds of HIPPS cycles under development. One team is led by the Foster Wheeler Development Corporation, the other team is led by the United Technologies Research Center. These cycles are described. Section 2 summarizes the feedback from the survey of the repowering needs of ten electric utility companies. The survey verified that the utility company planners favor a repowering for a first-of-a-kind demonstration of a new technology rather than an all-new-site application. These planners list the major factor in considering a unit as a repowering candidate as plant age: they identify plants built between 1955 and 1965 as the most likely candidates. Other important factors include the following: the need to reduce operating costs; the need to perform major maintenance/replacement of the boiler; and the need to reduce emissions. Section 3 reports the results of the market assessment. Using the size and age preferences identified in the survey, a market assessment was conducted (with the aid of a power plant data base) to estimate the number and characteristics of US generating units which constitute the current, primary potential market for coal-based repowering. Nearly 250 units in the US meet the criteria determined to be the potential repowering market.

Integrating Variable Renewable Energy in Electric Power Markets: Best Practices from International Experience, Summary for Policymakers  

DOE Green Energy (OSTI)

Many countries -- reflecting very different geographies, markets, and power systems -- are successfully managing high levels of variable renewable energy on the electric grid, including that from wind and solar energy. This document summarizes policy best practices that energy ministers and other stakeholders can pursue to ensure that electricity markets and power systems can effectively coevolve with increasing penetrations of variable renewable energy. There is no one-size-fits-all approach; each country studied has crafted its own combination of policies, market designs, and system operations to achieve the system reliability and flexibility needed to successfully integrate renewables. Notwithstanding this diversity, the approaches taken by the countries studied all coalesce around five strategic areas: lead public engagement, particularly for new transmission; coordinate and integrate planning; develop rules for market evolution that enable system flexibility; expand access to diverse resources and geographic footprint of operations; and improve system operations. This study also emphatically underscores the value of countries sharing their experiences. The more diverse and robust the experience base from which a country can draw, the more likely that it will be able to implement an appropriate, optimized, and system-wide approach.

DOE Green Energy (OSTI)

Many countries -- reflecting very different geographies, markets, and power systems -- are successfully managing high levels of variable renewable energy on the electric grid, including that from wind and solar energy. This study documents the diverse approaches to effective integration of variable renewable energy among six countries -- Australia (South Australia), Denmark, Germany, Ireland, Spain, and the United States (Western region-Colorado and Texas)-- and summarizes policy best practices that energy ministers and other stakeholders can pursue to ensure that electricity markets and power systems can effectively coevolve with increasing penetrations of variable renewable energy. Each country has crafted its own combination of policies, market designs, and system operations to achieve the system reliability and flexibility needed to successfully integrate renewables. Notwithstanding this diversity, the approaches taken by the countries studied all coalesce around five strategic areas: lead public engagement, particularly for new transmission; coordinate and integrate planning; develop rules for market evolution that enable system flexibility; expand access to diverse resources and geographic footprint of operations; and improve system operations. The ability to maintain a broad ecosystem perspective, to organize and make available the wealth of experiences, and to ensure a clear path from analysis to enactment should be the primary focus going forward.

Transportation Energy Futures Series: Projected Biomass Utilization for Fuels and Power in a Mature Market  

DOE Green Energy (OSTI)

The viability of biomass as transportation fuel depends upon the allocation of limited resources for fuel, power, and products. By focusing on mature markets, this report identifies how biomass is projected to be most economically used in the long term and the implications for greenhouse gas (GHG) emissions and petroleum use. In order to better understand competition for biomass between these markets and the potential for biofuel as a market-scale alternative to petroleum-based fuels, this report presents results of a micro-economic analysis conducted using the Biomass Allocation and Supply Equilibrium (BASE) modeling tool. The findings indicate that biofuels can outcompete biopower for feedstocks in mature markets if research and development targets are met. The BASE tool was developed for this project to analyze the impact of multiple biomass demand areas on mature energy markets. The model includes domestic supply curves for lignocellulosic biomass resources, corn for ethanol and butanol production, soybeans for biodiesel, and algae for diesel. This is one of a series of reports produced as a result of the Transportation Energy Futures (TEF) project, a Department of Energy-sponsored multi-agency project initiated to pinpoint underexplored strategies for abating GHGs and reducing petroleum dependence related to transportation.

with other commodities, electricity is often traded on both forward and spot As This was initially true in the restructured California electricity industry markets. 1998 to 2000. Though the power traded in the forward and spot markets from for delivery at the same times and locations, prices often differed in significant was predictable ways. We consider several explanations for this apparent inefficiency, and that uncertainty about regulatory penalties for trading in the spot market concluding most firms to avoid trading on inter-market price differences. The few firms caused did carry out these trades did not find it profit-maximizing to eliminate the that differences. Skyrocketing prices in the summer of 2000, however, changed the price buyers ’ (utilities’) incentives and increased the price differentials between the major markets.

Auxiliary resonant DC tank converter  

SciTech Connect

An auxiliary resonant dc tank (ARDCT) converter is provided for achieving soft-switching in a power converter. An ARDCT circuit is coupled directly across a dc bus to the inverter to generate a resonant dc bus voltage, including upper and lower resonant capacitors connected in series as a resonant leg, first and second dc tank capacitors connected in series as a tank leg, and an auxiliary resonant circuit comprising a series combination of a resonant inductor and a pair of auxiliary switching devices. The ARDCT circuit further includes first clamping means for holding the resonant dc bus voltage to the dc tank voltage of the tank leg, and second clamping means for clamping the resonant dc bus voltage to zero during a resonant period. The ARDCT circuit resonantly brings the dc bus voltage to zero in order to provide a zero-voltage switching opportunity for the inverter, then quickly rebounds the dc bus voltage back to the dc tank voltage after the inverter changes state. The auxiliary switching devices are turned on and off under zero-current conditions. The ARDCT circuit only absorbs ripples of the inverter dc bus current, thus having less current stress. In addition, since the ARDCT circuit is coupled in parallel with the dc power supply and the inverter for merely assisting soft-switching of the inverter without participating in real dc power transmission and power conversion, malfunction and failure of the tank circuit will not affect the functional operation of the inverter; thus a highly reliable converter system is expected.

Impacts of Western Area Power Administration`s power marketing alternatives on retail electricity rates and utility financial viability  

SciTech Connect

Changes in power contract terms for customers of Western`s Salt Lake City Area Office affect electricity rates for consumers of electric power in Arizona, Colorado, Nevada, New Mexico, Utah, and Wyoming. The impacts of electricity rate changes on consumers are studied by measuring impacts on the rates charged by individual utility systems, determining the average rates in regional areas, and conducting a detailed rate analysis of representative utility systems. The primary focus is an evaluation of the way retail electricity rates for Western`s preference customers vary with alternative pricing and power quantity commitment terms under Western`s long-term contracts to sell power (marketing programs). Retail rate impacts are emphasized because changes in the price of electricity are the most direct economic effect on businesses and residences arising from different Western contractual and operational policies. Retail rates are the mechanism by which changes in cost associated with Western`s contract terms are imposed on ultimate consumers, and rate changes determine the dollar level of payments for electric power incurred by the affected consumers. 41 figs., 9 tabs.

Regional economic impacts of changes in electricity rates resulting from Western Area Power Administration`s power marketing alternatives  

SciTech Connect

This technical memorandum describes an analysis of regional economic impacts resulting from changes in retail electricity rates due to six power marketing programs proposed by Western Area Power Administration (Western). Regional economic impacts of changes in rates are estimated in terms of five key regional economic variables: population, gross regional product, disposable income, employment, and household income. The REMI (Regional Impact Models, Inc.) and IMPLAN (Impact Analysis for Planning) models simulate economic impacts in nine subregions in the area in which Western power is sold for the years 1993, 2000, and 2008. Estimates show that impacts on aggregate economic activity in any of the subregions or years would be minimal for three reasons. First, the utilities that buy power from Western sell only a relatively small proportion of the total electricity sold in any of the subregions. Second, reliance of Western customers on Western power is fairly low in each subregion. Finally, electricity is not a significant input cost for any industry or for households in any subregion.

Review of the Structure of Bulk Power Markets Grid of the Future White Paper  

Science Conference Proceedings (OSTI)

This paper is intended to provide an understanding of the needs of a restructured electricity market and some of the market methods and systems that have developed to address those needs. Chapter 2 discusses the historic market framework of vertically integrated utilities. Chapter 3 introduces the changes to the vertically integrated utility brought about by restructuring. It discusses generation and transmission planning, control and the regulatory process. It also summarizes reliability, security and adequacy. Chapter 4 discusses the basic structures of generation and transmission markets along with transmission-congestion contracts (TCCs) and transmission pricing principles. A discussion is given of the 12 ancillary services needed to reliably operate the power system. Chapter 4 also deals with the role of transmission in opening up markets to competition. In California increments (incs) and decrements (decs) are bid to overcome price differences in different zones caused by congestion. In PJM, any member can purchase Fixed Transmission Rights (FTRs) which allows the member to ''collect rent'' on congested lines and essentially obtain a hedge against congestion. There has been a worrisome slowdown in the growth of the transmission system in the United States since about the mid 70's. However, there are methods for providing incentives for construction of new transmission using tariffs. The California and PJM transmission planning processes are outlined. The Federal Energy Regulatory Commission (FERC) has recently issued a proposed rulemaking on Regional Transmission Organizations (RTOs) which stated that the traditional methods of grid management are showing signs of strain and may be inadequate to support efficient and reliable transmission operations. Chapter 5 provides examples of market implementations and a discussion of the price spikes seen in the Midwest in the summers of 1998 and 1999. An examination of six restructured market systems is performed in some detail. The systems are California, PJM (Pennsylvania, New Jersey, Maryland), New England, United Kingdom (UK), Alberta, and Australia. Finally, there is a discussion of the price spikes that occurred in the Midwest this summer from the viewpoint of market performance. Chapter 6 deals with the concept of load as a resource. This is a novel idea that holds tremendous promise as technological advances permit real time control of loads based on the user's economic criteria. The user may be willing to curtail operations for some period of time when the spot price reaches a certain level, or the user may be willing to sell ancillary services to the system. Chapter 7 outlines the research needs presented by a restructured industry and the vital federal role in meeting these needs. Without federal participation, research to advance the public good will not be performed by an industry now focused on profit. Chapter 8 provides a summary and concluding remarks.

Socioeconomic effects of power marketing alternatives for the Central Valley and Washoe Projects: 2005 regional econmic impact analysis using IMPLAN  

DOE Green Energy (OSTI)

The Western Area Power Administration (Western) was founded by the Department of Energy Organization Act of 1977 to market and transmit federal hydroelectric power in 15 western states outside the Pacific Northwest, which is served by the Bonneville Power Administration. Western is divided into four independent Customer Service Regions including the Sierra Nevada Region (Sierra Nevada), the focus of this report. The Central Valley Project (CVP) and the Washoe Project provide the primary power resources marketed by Sierra Nevada. Sierra Nevada also purchases and markets power generated by the Bonneville Power Administration, Pacific Gas and Electric (PG&E), and various power pools. Sierra Nevada currently markets approximately 1,480 megawatts of power to 77 customers in northern and central California. These customers include investor-owned utilities, public utilities, government agencies, military bases, and irrigation districts. Methods and conclusions from an economic analysis are summarized concerning distributional effects of alternative actions that Sierra Nevada could take with it`s new marketing plan.

Estimating the Effects of Climate Change on Federal Hydropower and Power Marketing  

Science Conference Proceedings (OSTI)

The U.S. Department of Energy is currently preparing an assessment of the effects of climate change on federal hydropower, as directed by Congress in Section 9505 of the Secure Water Act of 2009 (P.L. 111-11). This paper describes the assessment approach being used in a Report to Congress currently being prepared by Oak Ridge National Laboratory. The 9505 assessment will examine climate change effects on water available for hydropower operations and the future power supplies marketed from federal hydropower projects. It will also include recommendations from the Power Marketing Administrations (PMAs) on potential changes in operation or contracting practices that could address these effects and risks of climate change. Potential adaption and mitigation strategies will also be identified. Federal hydropower comprises approximately half of the U.S. hydropower portfolio. The results from the 9505 assessment will promote better understanding among federal dam owners/operators of the sensitivity of their facilities to water availability, and it will provide a basis for planning future actions that will enable adaptation to climate variability and change. The end-users of information are Congressional members, their staff, the PMAs and their customers, federal dam owners/operators, and the DOE Water Power Program.

Current and Future Costs for Parabolic Trough and Power Tower Systems in the US Market: Preprint  

DOE Green Energy (OSTI)

NREL's Solar Advisor Model (SAM) is employed to estimate the current and future costs for parabolic trough and molten salt power towers in the US market. Future troughs are assumed to achieve higher field temperatures via the successful deployment of low melting-point, molten-salt heat transfer fluids by 2015-2020. Similarly, it is assumed that molten salt power towers are successfully deployed at 100MW scale over the same time period, increasing to 200MW by 2025. The levelized cost of electricity for both technologies is predicted to drop below 11 cents/kWh (assuming a 10% investment tax credit and other financial inputs outlined in the paper), making the technologies competitive in the marketplace as benchmarked by the California MPR.

Current and future costs for parabolic trough and power tower systems in the US market.  

SciTech Connect

NREL's Solar Advisor Model (SAM) is employed to estimate the current and future costs for parabolic trough and molten salt power towers in the US market. Future troughs are assumed to achieve higher field temperatures via the successful deployment of low melting-point, molten-salt heat transfer fluids by 2015-2020. Similarly, it is assumed that molten salt power towers are successfully deployed at 100MW scale over the same time period, increasing to 200MW by 2025. The levelized cost of electricity for both technologies is predicted to drop below 11 cents/kWh (assuming a 10% investment tax credit and other financial inputs outlined in the paper), making the technologies competitive in the marketplace as benchmarked by the California MPR. Both technologies can be deployed with large amounts of thermal energy storage, yielding capacity factors as high as 65% while maintaining an optimum LCOE.

ORCED: A model to simulate the operations and costs of bulk-power markets  

SciTech Connect

Dramatic changes in the structure and operation of US bulk-power markets require new analytical tools. The authors developed the Oak Ridge Competitive Electricity Dispatch (ORCED) model to analyze a variety of public-policy issues related to the many changes underway in the US electricity industry. Such issues include: policy and technology options to reduce carbon emissions from electricity production; the effects of electricity trading between high- and low-cost regions on consumers and producers in both regions; the ability of the owners of certain generating units to exercise market power as functions of the transmission link between two regions and the characteristics of the generating units and loads in each region; and the market penetration of new energy-production and energy-use technologies and the effects of their adoption on fuel use, electricity use and costs, and carbon emissions. ORCED treats two electrical systems connected by a single transmission link ORCED uses two load-duration curves to represent the time-varying electricity consumption in each region. The two curves represent peak and offpeak seasons. User specification of demand elasticities permits ORCED to estimate the effects of changes in electricity price, both overall and hour by hour, on overall electricity use and load shapes. ORCED represents the electricity supply in each region with 26 generating units. The two regions are connected by a single transmission link. This link is characterized by its capacity (MW), cost ({cents}/kWh), and losses (%). This report explains the inputs to, outputs from, and operation of ORCED. It also presents four examples showing applications of the model to various public-policy issues related to restructuring of the US electricity industry.

Bi-Directional DC-DC Converter for PHEV Applications  

DOE Green Energy (OSTI)

Plug-In Hybrid Electric Vehicles (PHEV) require high power density energy storage system (ESS) for hybrid operation and high energy density ESS for Electric Vehicle (EV) mode range. However, ESS technologies to maximize power density and energy density simultaneously are not commercially feasible. The use of bi-directional DC-DC converter allows use of multiple energy storage, and the flexible DC-link voltages can enhance the system efficiency and reduce component sizing. This will improve fuel consumption, increase the EV mode range, reduce the total weight, reduce battery initial and life cycle cost, and provide flexibility in system design.

Utility-Scale Concentrating Solar Power and Photovoltaic Projects: A Technology and Market Overview  

DOE Green Energy (OSTI)

Over the last several years, solar energy technologies have been, or are in the process of being, deployed at unprecedented levels. A critical recent development, resulting from the massive scale of projects in progress or recently completed, is having the power sold directly to electric utilities. Such 'utility-scale' systems offer the opportunity to deploy solar technologies far faster than the traditional 'behind-the-meter' projects designed to offset retail load. Moreover, these systems have employed significant economies of scale during construction and operation, attracting financial capital, which in turn can reduce the delivered cost of power. This report is a summary of the current U.S. utility-scale solar state-of-the-market and development pipeline. Utility-scale solar energy systems are generally categorized as one of two basic designs: concentrating solar power (CSP) and photovoltaic (PV). CSP systems can be further delineated into four commercially available technologies: parabolic trough, central receiver (CR), parabolic dish, and linear Fresnel reflector. CSP systems can also be categorized as hybrid, which combine a solar-based system (generally parabolic trough, CR, or linear Fresnel) and a fossil fuel energy system to produce electric power or steam.

Extending the Constant Power Speed Range of the Brushless DC Motor through Dual Mode Inverter Control -- Part I: Theory and Simulation  

SciTech Connect

An inverter topology and control scheme has been developed that can drive low-inductance, surface-mounted permanent magnet motors over the wide constant power speed range required in electric vehicle applications. This new controller is called the dual-mode inverter control (DMIC) [1]. The DMIC can drive either the Permanent Magnet Synchronous Machine (PMSM) with sinusoidal back emf, or the brushless dc machine (BDCM) with trapezoidal emf in the motoring and regenerative braking modes. In this paper we concentrate on the BDCM under high-speed motoring conditions. Simulation results show that if all motor and inverter loss mechanisms are neglected, the constant power speed range of the DMIC is infinite. The simulation results are supported by closed form expressions for peak and rms motor current and average power derived from analytical solution to the differential equations governing the DMIC/BDCM drive for the lossless case. The analytical solution shows that the range of motor inductance that can be accommodated by the DMIC is more than an order of magnitude such that the DMIC is compatible with both low- and high-inductance BDCMs. Finally, method is given for integrating the classical hysteresis band current control, used for motor control below base speed, with the phase advance of DMIC that is applied above base speed. The power versus speed performance of the DMIC is then simulated across the entire speed range.

The potential impact of externalities considerations on the market for biomass power technologies  

Science Conference Proceedings (OSTI)

This study assesses the current status of externalities considerations--nonmarket costs and benefits--in state and utility electricity resource planning processes and determines how externalities considerations might help or hinder the development of biomass power plants. It provides an overview of biomass resources and technologies, including their market status and environmental impacts; reviews the current treatment of externalities in the states; and documents the perspectives of key utility, regulatory, and industry representatives concerning externalities considerations. The authors make the following recommendations to the biomass industry: (1) the wood and agricultural waste industries should work toward having states and utilities recognize that wood and agricultural waste are greenhouse gas neutral resources because of carbon sequestration during growth; (2) the biomass industry should emphasize nonenvironmental benefits such as economic development and job creation; and (3) the biomass industry should pursue and support efforts to establish renewable energy set-asides or ``green`` requests for proposals.

Technology Advancements to Support Growth in Geothermal Power Sales in a Dynamic Utility Market  

SciTech Connect

We are assembled today to discuss the opportunities and challenges for expanding the sales of geothermally-generated electric power in a competitive utility market. First, however, I would like to note that growth in geothermal sales might not be a germane topic were it not for the early participation in the development of the geothermal industry by utilities themselves. Without their contributions to research and development, environmental breakthroughs, and, perhaps, above all, their early use of geothermal power and continuing investment in the industry, we might still be at ''Square One''--confronting inhibiting doubts of the energy utilization industry. I feel certain that utility involvement has served to inspire far greater confidence in the reliability of the resource on the part of other utilities and other investors than could have been generated by federal programs and/or the resource developer arm of the geothermal community. While acknowledging that we have not completely resolved all problems which geothermal energy faced 20 years ago--confidence, institutional restraints, environmental compliance, and technical and economic uncertainties--this audience and our predecessors have addressed them, individually and collectively, and, to a large extent, we have surmounted them. But it took generation or contracted purchase of geothermal power by utilities--whatever their discrete reasons for doing so--to demonstrate to the public and government regulators that there is a place for geothermal power in the service areas of large utilities. In addition, in using an alternative fuel, the participating utilities have already exposed themselves to changing concepts and practices in their industry.

DOE: Integrating Southwest Power Pool Wind Energy into Southeast Electricity Markets  

DOE Green Energy (OSTI)

Wind power development in the United States is outpacing previous estimates for many regions, particularly those with good wind resources. The pace of wind power deployment may soon outstrip regional capabilities to provide transmission and integration services to achieve the most economic power system operation. Conversely, regions such as the Southeastern United States do not have good wind resources and will have difficulty meeting proposed federal Renewable Portfolio Standards with local supply. There is a growing need to explore innovative solutions for collaborating between regions to achieve the least cost solution for meeting such a renewable energy mandate. The DOE-funded project 'Integrating Southwest Power Pool Wind Energy into Southeast Electricity Markets' aims to evaluate the benefits of coordination of scheduling and balancing for Southwest Power Pool (SPP) wind transfers to Southeastern Electric Reliability Council (SERC) Balancing Authorities (BAs). The primary objective of this project is to analyze the benefits of different balancing approaches with increasing levels of inter-regional cooperation. Scenarios were defined, modeled and investigated to address production variability and uncertainty and the associated balancing of large quantities of wind power in SPP and delivery to energy markets in the southern regions of the SERC. The primary analysis of the project is based on unit commitment (UC) and economic dispatch (ED) simulations of the SPP-SERC regions as modeled for the year 2022. The UC/ED models utilized for the project were developed through extensive consultation with the project utility partners, to ensure the various regions and operational practices are represented as accurately as possible realizing that all such future scenario models are quite uncertain. SPP, Entergy, Oglethorpe Power Company (OPC), Southern Company, and the Tennessee Valley Authority (TVA) actively participated in the project providing input data for the models and review of simulation results and conclusions. While other SERC utility systems are modeled, the listed SERC utilities were explicitly included as active participants in the project due to the size of their load and relative proximity to SPP for importing wind energy. The analysis aspects of the project comprised 4 primary tasks: (1) Development of SCUC/SCED model of the SPP-SERC footprint for the year 2022 with only 7 GW of installed wind capacity in SPP for internal SPP consumption with no intended wind exports to SERC. This model is referred to as the 'Non-RES' model as it does not reflect the need for the SPP or SERC BAs to meet a federal Renewable Energy Standard (RES). (2) Analysis of hourly-resolution simulation results of the Non-RES model for the year 2022 to provide project stakeholders with confidence in the model and analytical framework for a scenario that is similar to the existing system and more easily evaluated than the high-wind transfer scenarios that are analyzed subsequently. (3) Development of SCUC/SCED model of the SPP-SERC footprint for the year 2022 with sufficient installed wind capacity in SPP (approximately 48 GW) for both SPP and the participating SERC BAs to meet an RES of 20% energy. This model is referred to as the 'High-Wind Transfer' model with several different scenarios represented. The development of the High-Wind Transfer model not only included identification and allocation of SPP wind to individual SERC BAs, but also included the evaluation of various methods to allow the model to export the SPP wind to SERC without developing an actual transmission plan to support the transfers. (4) Analysis of hourly-resolution simulation results of several different High-Wind Transfer model scenarios for the year 2022 to determine balancing costs and potential benefits of collaboration among SPP and SERC BAs to provide the required balancing.

Surpassing Expectations: State of the U.S. Wind Power Market  

SciTech Connect

The wind power industry in the U.S. has been on a growth binge in recent years, and the rapid pace of development has made it difficult to keep up with trends in the marketplace. Yet the need for timely, objective information on the wind industry and its progress has never been greater. This article, excerpted from a longer report from the U.S. Department of Energy, attempts to fill this need by providing a comprehensive, yet detailed, overview of key developments in the U.S. wind power market, with a particular focus on 2007. This summary includes information on wind project installation trends, industry developments, and, perhaps most interestingly, project-level installed cost and pricing information that has not otherwise been widely reported. The article concentrates on larger-scale wind applications, defined here as projects utilizing turbines that exceed 50 kW in size. In many cases, the data reported here represent only a sample of all wind projects installed in the United States; furthermore, the data vary in quality. As such, emphasis should be placed on overall trends in the data, rather than on individual data points.

Coordinated Control and Optimization of Virtual Power Plants for Energy and Frequency Regulation Services in Electricity Markets  

E-Print Network (OSTI)

With increasing penetration of intermittent resources such as wind and solar, power system operations are facing much more challenges in cost effective provision of energy balancing and frequency regulation services. Enabled by advances in sensing, control and communication, the concept of Virtual Power Plant (VPP) is proposed as one possible solution which aggregates and firms up spatially distributed resources? net power injection to the system. This thesis proposes a coordinated control and bidding strategy for VPPs to provide energy balancing and grid frequency regulation services in electricity market environment. In this thesis, the VPP consists of two energy conversion assets: a Doubly Fed Induction Generator (DFIG)-based wind farm and a co-located Flywheel Energy Storage System (FESS). The coordination of the VPP is implemented through power electronics?based controllers. A five-bus system test case demonstrates the technical feasibility of VPPs to respond to grid frequency deviation as well as to follow energy dispatch signals. To enable the participation of VPPs in electricity market, this thesis also proposes an optimization based bidding strategy for VPPs in both energy balancing and frequency regulation service markets. The potential economic benefits of this bidding strategy are demonstrated under Denmark wholesale electricity market structure. Four case studies show the economic benefit of coordinating VPPs.

Commercialization of coal diesel engines for non-utility and export power markets  

DOE Green Energy (OSTI)

The basic motivation behind this project is to develop coal-burning heat engine technology primarily for 10-100 MW modular stationary power applications in the late 1990`s and beyond, when oil and gas prices may return to the $5--7/MMBtu range. The fuel is a low-cost, coal-based liquid with the consistency of black paint, composed of 12-micron mean size premium 2% ash coal dust mixed 50/50 with water. The Clean Coal Diesel Plant of the future is targeted for the 10-100 MW non-utility generation (NUG) and small utility markets, including independent power producers (IPP) and cogeneration. A family of plant designs will be offered using the Cooper-Bessemer 3.8, 5.0, and 6.3 MW Model LS engines as building blocks. In addition, larger plants will be configured with an engine in the 10-25 MW class (Cooper will license the technology to other large bore stationary engine manufacturers). The reciprocating engine offers a remarkable degree of flexibility in selecting plant capacity. This flexibility exists because the engines are modular in every sense (fuel cell stacks have similar modularity). Scale-up is accomplished simply by adding cylinders (e.g., 20 vs 16) or by adding engines (4 vs 3). There is no scale-up of the basic cylinder size. Thus, there is essentially no technical development needed to scale-up the Cooper-Bessemer Clean Coal Diesel Technology all the way from 2 MW (one 6-cylinder engine) to 50 MW (eight 20-cylinder engines), other than engineering adaptation of the turbocharger to match the engine.

Extending the Constant Power Speed Range of the Brushless DC Motor through Dual Mode Inverter Control -- Part II: Laboratory Proof-of-Principle  

DOE Green Energy (OSTI)

Previous theoretical work has shown that when all loss mechanisms are neglected the constant power speed range (CPSR) of a brushless dc motor (BDCM) is infinite when the motor is driven by the dual-mode inverter control (DMIC) [1,2]. In a physical drive, losses, particularly speed-sensitive losses, will limit the CPSR to a finite value. In this paper we report the results of laboratory testing of a low-inductance, 7.5-hp BDCM driven by the DMIC. The speed rating of the test motor rotor limited the upper speed of the testing, and the results show that the CPSR of the test machine is greater than 6:1 when driven by the DMIC. Current wave shape, peak, and rms values remained controlled and within rating over the entire speed range. The laboratory measurements allowed the speed-sensitive losses to be quantified and incorporated into computer simulation models, which then accurately reproduce the results of lab testing. The simulator shows that the limiting CPSR of the test motor is 8:1. These results confirm that the DMIC is capable of driving low-inductance BDCMs over the wide CPSR that would be required in electric vehicle applications.

2007 Wholesale Power Rate Case Initial Proposal : Market Price Forecast Study.  

SciTech Connect

This chapter presents BPA's market price forecasts, which are based on AURORA modeling. AURORA calculates the variable cost of the marginal resource in a competitively priced energy market. In competitive market pricing, the marginal cost of production is equivalent to the market-clearing price. Market-clearing prices are important factors for informing BPA's rates. AURORA is used as the primary tool for (a) calculation of the demand rate, (b) shaping the PF rate, (c) estimating the forward price for the IOU REP settlement benefits calculation for fiscal years 2008 and 2009, (d) estimating the uncertainty surrounding DSI payments, (e) informing the secondary revenue forecast and (f) providing a price input used for the risk analysis.

Optimizing Energy Savings from Direct-DC in U.S. Residential Buildings  

DOE Green Energy (OSTI)

An increasing number of energy efficient appliances operate on direct current (DC) internally, offering the potential to use DC from renewable energy systems directly and avoiding the losses inherent in converting power to alternating current (AC) and back. This paper investigates that potential for net-metered residences with on-site photovoltaics (PV) by modeling the net power draw of the ‘direct-DC house’ with respect to today’s typical configuration, assuming identical DC-internal loads. Power draws were modeled for houses in 14 U.S. cities, using hourly, simulated PV-system output and residential loads. The latter were adjusted to reflect a 33% load reduction, representative of the most efficient DC-internal technology, based on an analysis of 32 electricity end-uses. The model tested the effect of climate, electric vehicle (EV) loads, electricity storage, and load shifting on electricity savings; a sensitivity analysis was conducted to determine how future changes in the efficiencies of power system components might affect savings potential. Based on this work, we estimate that net-metered PV residences could save 5% of their total electricity load for houses without storage and 14% for houses with storage. Based on residential PV penetration projections for year 2035 obtained from the National Energy Modeling System (2.7% for the reference case and 11.2% for the extended policy case), direct-DC could save the nation 10 trillion Btu (without storage) or 40 trillion Btu (with storage). Shifting the cooling load by two hours earlier in the day (pre-cooling) has negligible benefits for energy savings. Direct-DC provides no energy savings benefits for EV charging, to the extent that charging occurs at night. However, if charging occurred during the day, for example with employees charging while at work, the benefits would be large. Direct-DC energy savings are sensitive to power system and appliance conversion efficiencies but are not significantly influenced by climate. While direct-DC for residential applications will most likely arise as a spin-off of developments in the commercial sector—because of lower barriers to market entry and larger energy benefits resulting from the higher coincidence between load and insolation—this paper demonstrates that there are substantial benefits in the residential sector as well. Among residential applications, space cooling derives the largest energy savings from being delivered by a direct-DC system. It is the largest load for the average residence on a national basis and is particularly so in high-load regions. It is also the load with highest solar coincidence.

Salt Lake City Area Integrated Projects Electric Power Marketing. Draft environmental impact statement: Volume 4, Appendixes B-D  

SciTech Connect

The Salt Lake City Area Office of the Western Area Power Administration (Western) markets electricity produced at hydroelectric facilities operated by the Bureau of Reclamation. The facilities are known collectively as the Salt Lake City Area Integrated Projects (SLCA/IP) and include dams equipped for power generation on the Green, Gunnison, Rio Grande, and Colorado rivers and on Deer and Plateau creeks in the states of Wyoming, Utah, Colorado, Arizona, and New Mexico. Of these facilities, only the Glen Canyon Unit, the Flaming Gorge Unit, and the Aspinall Unit (which includes Blue Mesa, Morrow Point, and Crystal dams;) are influenced by Western power scheduling and transmission decisions. The EIS alternatives, called commitment-level alternatives, reflect combinations of capacity and energy that would feasibly and reasonably fulfill Westerns firm power marketing responsibilities, needs, and statutory obligations. The viability of these alternatives relates directly to the combination of generation capability of the SLCA/IP with energy purchases and interchange. The economic and natural resource assessments in this environmental impact statement (EIS) include an analysis of commitment-level alternatives. Impacts of the no-action alternative are also assessed. Supply options, which include combinations of electrical power purchases and hydropower operational scenarios reflecting different operations of the dams, are also assessed. The EIS evaluates the impacts of these scenarios relative to socioeconomics, air resources, water resources, ecological resources, cultural resources, land use, recreation, and visual resources.

Policies and Market Factors Driving Wind Power Development in the United States  

DOE Green Energy (OSTI)

In the United States, there has been substantial recent growth in wind energy generating capacity, with growth averaging 24% annually during the past five years. With this growth, an increasing number of states are experiencing investment in wind energy. Wind installations currently exist in about half of all U.S. states. This paper explores the policies and market factors that have been driving utility-scale wind energy development in the United States, particularly in the states that have achieved a substantial amount of wind energy investment in recent years. Although there are federal policies and overarching market issues that are encouraging investment nationally, much of the recent activity has resulted from state-level policies or localized market drivers. In this paper, we identify the key policies, incentives, regulations, and markets affecting development, and draw lessons from the experience of leading states that may be transferable to other states or regions. We provide detailed discussions of the drivers for wind development in a dozen leading states-California, Colorado, Iowa, Kansas, Minnesota, New York, Oregon, Pennsylvania, Texas, Washington, West Virginia, and Wyoming.

Wind Generators and Market Power: Does it matter who owns them?  

E-Print Network (OSTI)

Electricity production from wind generators holds significant importance in European Union’s 20 % renewable energy target by 2020. In this paper, I show that ownership of wind generators affects market outcomes by using both a Cournot oligopoly model and a real options model. In the Cournot oligopoly model, ownership of the wind generators by owners of fossil-fueled (peakload) generators decreases total peakload production and increases the market price. These effects increase with total wind generation and aggregate wind generator ownership. In the real options model, start up and shut down price thresholds are significantly higher when the monopolist at the peakload level owns both types of generators. Furthermore, when producing electricity with the peakload generator, the monopolist can avoid facing prices below marginal cost by owning a certain share of the wind generators.

The Long-Term Market Potential of Concentrating Solar Power (CSP) Systems  

Science Conference Proceedings (OSTI)

This chapter will examine the conditions under which thermal CSP systems might play a large role in the global energy system. CSP technologies, such as troughs or power towers, have a large advantage over other solar technologies in that they offer the potential for firm power delivery, mitigating intermittency issues. These systems require relatively cloud-free conditions to operate, which limits their geographic applicability.

Impacts of Western Area Power Administration`s power marketing alternatives on utility demand-side management and conservation and renewable energy programs  

SciTech Connect

The Western Area Power Administration (Western) requires all of its long-term firm power customers to implement programs that promote the conservation of electric energy or facilitate the use of renewable energy resources. Western has also proposed that all customers develop integrated resource plans that include cost-effective demand-side management programs. As part of the preparation of Western`s Electric Power Marketing Environmental Impact Statement, Argonne National Laboratory (ANL) developed estimates of the reductions in energy demand resulting from Western`s conservation and renewable energy activities in its Salt Lake City Area Office. ANL has also estimated the energy-demand reductions from cost-effective, demand-side management programs that could be included in the integrated resource plans of the customers served by Western`s Salt Lake City Area Office. The results of this study have been used to adjust the expected hourly demand for Western`s major systems in the Salt Lake City Area. The expected hourly demand served as the basis for capacity expansion plans develops with ANL`s Production and Capacity Expansion (PACE) model.

Optimizing Energy Savings from Direct-DC in U.S. Residential Buildings Optimizing Energy Savings from Direct-DC in U.S. Residential Buildings Title Optimizing Energy Savings from Direct-DC in U.S. Residential Buildings Publication Type Report LBNL Report Number LBNL-5193E Year of Publication 2011 Authors Garbesi, Karina, Vagelis Vossos, Alan H. Sanstad, and Gabriel Burch Document Number LBNL-5193E Pagination 59 Date Published October Publisher Lawrence Berkeley National Laboratory City Berkeley Abstract An increasing number of energy efficient appliances operate on direct current (DC) internally, offering the potential to use DC from renewable energy systems directly and avoiding the losses inherent in converting power to alternating current (AC) and back. This paper investigates that potential for net-metered residences with on-site photovoltaics (PV) by modeling the net power draw of the 'direct-DC house' with respect to today's typical configuration, assuming identical DC-internal loads. Power draws were modeled for houses in 14 U.S. cities, using hourly, simulated PV-system output and residential loads. The latter were adjusted to reflect a 33% load reduction, representative of the most efficient DC-internal technology, based on an analysis of 32 electricity end-uses. The model tested the effect of climate, electric vehicle (EV) loads, electricity storage, and load shifting on electricity savings; a sensitivity analysis was conducted to determine how future changes in the efficiencies of power system components might affect savings potential. Based on this work, we estimate that net-metered PV residences could save 5% of their total electricity load for houses without storage and 14% for houses with storage. Based on residential PV penetration projections for year 2035 obtained from the National Energy Modeling System (2.7% for the reference case and 11.2% for the extended policy case), direct-DC could save the nation 10 trillion Btu (without storage) or 40 trillion Btu (with storage). Shifting the cooling load by two hours earlier in the day (pre-cooling) has negligible benefits for energy savings. Direct-DC provides no energy savings benefits for EV charging, to the extent that charging occurs at night. However, if charging occurred during the day, for example with employees charging while at work, the benefits would be large. Direct-DC energy savings are sensitive to power system and appliance conversion efficiencies but are not significantly influenced by climate. While direct-DC for residential applications will most likely arise as a spin-off of developments in the commercial sector-because of lower barriers to market entry and larger energy benefits resulting from the higher coincidence between load and insolation-this paper demonstrates that there are substantial benefits in the residential sector as well. Among residential applications, space cooling derives the largest energy savings from being delivered by a direct-DC system. It is the largest load for the average residence on a national basis and is particularly so in high-load regions. It is also the load with highest solar coincidence.

Summary.html[6/24/2011 3:03:56 PM] Summary.html[6/24/2011 3:03:56 PM] SUMMARY S.1 DESCRIPTION OF THE PROPOSED ACTION The Western Area Power Administration (Western) proposes to establish the level of its commitment (sales) of long- term firm electrical capacity and energy from the Salt Lake City Area Integrated Projects (SLCA/IP) hydroelectric power plants. Power generated by the SLCA/IP facilities or purchased by Western from other sources is provided to Western's customers under contracts that establish the terms for how capacity (generation capacity) and energy (quantity of electrical energy) are to be sold. The contracts also specify amounts of capacity and energy that Western agrees to offer for long-term (greater than 12 months) sale to its customers. These amounts constitute Western's
