AbstractAbstract
[en] A methodology for demand forecast of consumer classes and their aggregation is presented. An analysis of the actual attended market can be done by appropriate measures and load curves studies. The suppositions for the future market behaviour by consumer classes (industrial, residential, commercial, others) are shown, and the actions for optimise this market are foreseen, obtained by load curves modulations. The process of future demand determination is obtained by the appropriate aggregation of this segmented demands. (C.G.C.)

AbstractAbstract
[en] The purpose of this study is to examine competition in the electric power industry from an ''industrial organization'' point of view. The remainder of this report is organized as follows. Chapter 2 describes the ''industrial organization'' approach used to analyze the electric power market. Industrial organization emphasizes specific market performance criteria, and the impact of market structure and behavior on performance. Chapter 3 identifies the participants in the electric power market, grouped primarily into regulated producers, unregulated producers, and consumers. Chapter 4 describes the varieties of electric power competition, organized along two dimensions: producer competition and consumer competition. Chapters 5 and 6 identify the issues raised by competition along the two dimensions. These issues include efficiency, equity, quality, and stability. Chapters 7 through 9 describe market structure, behavior and performance in three competitive scenarios: minimum competition, maximum competition, and moderate competition. Market structure, behavior and performance are discussed, and the issues raised in Chapters 5 and 6 are discussed in detail. Chapter 10 provides conclusions about ''winners and losers'' and identifies issues that require further study

AbstractAbstract
[en] SEEBOARD plc is the company which, since the privatization of the electricity supply industry in the United Kingdom, has undertaken the distribution and supply of electric power to consumers in south eastern England. The Chief Executive of the company in his review for 1992 reports a profit of Pound 91.5m from the distribution business and Pound 4.2m from the supply business; profits for the previous year were Pound 64.2m and Pound 7.2m respectively. Other businesses, which include the retailing of electrical goods, electrical contracting, and a joint venture with WilCorp UK Ltd. to market and supply natural gas in Southern England, contributed Pound 2m to the company profits. Details of the company's operations and principal activities are given in the report and the annual accounts are presented. (UK)

AbstractAbstract
[en] The main subjective of this thesis is to analyse the effects of the growth of the tertiary sector on the electric power demand. In order to accomplish this goal an economical and social, analysis of the tertiary sector is made to identify its dynamic, its relations with the other sectors of the economy and to describe the methodologies for measuring the overall tertiary production. Afterwards it is made an analysis of the electric power consumption evolution in the tertiary sector, in order to identify the consumption per region of the country, per consumers and tertiary subsectors. It is also analysed the product power intensify and, finally its described the present tariff system. (author)

AbstractAbstract
[en] The electric power consumption in the residential, commercial and industrial Brazilian sectors and in the five Brazilian regions during the month of August 1993 is described. The industrial production indexes, the cost of tariffs and fuel consumption and the evolution of own load energy and the energy demand are also shown. (C.G.C.)

AbstractAbstract
[en] The characteristics and performance of the electric utilities operating in the south-east and center-west regions of Brazil are presented. These regions consume 70% of all the electric power produced in the country. The informations supplied in this report include for each regions the characteristics of the system, the demand and growth rate and the electricity consumed by the industrial, commercial and residential sectors. 44 figs., 134 tabs

AbstractAbstract
[en] This paper presents the interactive distribution load forecast application that performs the distribution load forecast with interactive correction of horizon loads. It consists of two major parts implemented in Fortran and Visual Basic. The Fortran part is used for the forecasts computations. It consists of two methods: Load Transfer Coupling Curve Fitting (LTCCF) and load Forecast Using Curve Shape Clustering (FUCSC). LTCCF is used to 'correct' the contaminated data because of load transfer among neighboring distribution areas. FUCSC uses curve shape clustering to forecast the distribution loads of small areas. The forecast for each small area is achieved by using the shape of corresponding cluster curve. The comparison of forecasted loads of the area with historical data will be used as a tool for the correction of the estimated horizon load. The Visual Basic part is used to provide flexible interactive user-friendly environment. (author). 5 refs., 3 figs

AbstractAbstract
[en] The paper defines and classifies essential issues that relate the need for electric power system coordination with the increasing development of competition. Principles are formulated and a coordination model and a market structure are proposed, emphasizing the need for economic dispatch in the wholesale market. A detailed comparison is made of the market and pooling implementations developed in Argentina and Chile, countries that have pioneered the creation of competitive markets in the electric energy sector. An evaluation of strengths and weaknesses of those two implementations is included

AbstractAbstract
[en] The electric utility industry is in the beginning throes of a transformation from a cost-based regulated structure to a more market based less regulated system. Traditional unit commitment and economic dispatch methodologies can continue to provide reliable least-cost solutions, providing they are modified to accommodate a larger sphere of market participants. This paper offers a method for an entity such as an Independent System Operator (ISO) to solicit and evaluate bids for developing a spot priced electric market by replicating existing utility practices that are effective and efficient, while creating an open and equitable competitive marketplace for electricity

AbstractAbstract
[en] Electrical utilities are currently facing adverse forces which make their planning task and the construction of new transmission network structures very difficult. An analysis is proposed for providing possible solutions to this issue in the future. Two time scales are considered. In the next decade, the technical feasibility of 400 kV extruded cables and Compressed Gas Insulated Cables (CGIC) is likely to be demonstrated. In the longer term, superconductive cable systems and certain technologies for small dispersed generation and storage sources are likely to approach break-even rates. A great deal of R and D efforts are still required in order to reach this point. For these efforts to be successful, the way the utilities consider the development of their generation, transmission and distribution system would have to be considerably modified. (author)
