Abstract
The author describes how available statistics and consumer participation indicate that, though not perfect, the benefits of UK electric utility privatization and competition outweigh the monopolistic structures of the past.
... Electric power industry in many countries was transformed from the vertically integrated structure towards unbundling. Different aspects of these reforms were discussed on the cases of Great Britain (Lamoureux, 2001a(Lamoureux, , 2001bSurrey, 1996), USA (Barkovich & Hawk, 1996), Argentina and Chili (Pollitt, 2008a;Rudnick, 1996), and many other countries all over the world. Due to the reforms energy generation and distribution became competitive sectors, but the transmission is considered by most researchers as a natural monopoly despite the opposite position of some economists (DiLorenzo, 1996;Gordon, 1982). ...
This paper discusses how mandatory ownership unbundling and government-granted monopoly privileges in electricity transmission affect electricity prices. Aprioristic mathematical modeling taking into account potential competition is used. The models considered show that consumers can benefit from the regulation of the transmission monopoly only if the monopoly is subsidized or its costs are much lower than the maximum possible revenue. It is shown that potential competition and the absence of monopoly privileges in electricity transmission can decrease prices even when entry barriers are high. It is shown that mandatory ownership unbundling can nearly eliminate the effect of potential competition in transmission.
The restructuring and deregulation of the electric power sector has had a long-term history in many countries. The sector management and government of each country endeavors to apply positive experiences from other countries, taking into account technical and economic conditions and features of their own power sector. The article describes the main characteristics of the power sectors in Russia and the UK, as well as concepts and principles of the power sectors liberalization. The basic benefits of and differences between the reforming policies in both countries are shown. Although some elements of the Russia-UK power sector liberalization experience can hold less comparative value, the analytical comparison of aims and main components of the liberalization process, such as the principles of privatization, structure of property, competition promotion, and regulation practice can enhance policy learning.
Supplying electrical energy economically to the customers is very important to cater to the needs of the distribution area effectively. The sensitivity of dispatch of quality power always depends on the reliability of the power system. Deregulated power system environment is increasing rapidly, and the power system reliability functions play effectively in the operation. Reliability always depends on the continuity and the quality of power system which susceptible to interruption. In the deregulated power diligence, the complexity of the power disturbances depends on the deficiencies in the transmission and distribution networks which are controlled by the transmission system operators and the system aggregators. This paper explains the research done at the three major areas in the test system which includes modeling of generator units, identification of transmission deficiencies, and reliability performance. Also, this paper proposes the effective method to enhance power system reliability and the way to modify the existing system through derated adjusted forced outage rate in the transmission and distribution network.
This paper presents a load frequency control design for interconnected electric power systems using a set of fuzzy logic rules. The design objectives are (i) to comply with the North American Electric Reliability Council's (NERC) control performance standards, CPS1 and CPS2, (ii) to reduce wear and tear of generating unit's equipments, and (iii) to design a feasible control structure. A test system with multiple generation and distribution companies that takes into account regulation and load following services is used to demonstrate the effectiveness of the proposed methodologies.
This paper presents the advancement in power system engineering education and research with power industry moving towards deregulation. Deregulation is a relatively recent concept, whose economic, regulatory and implementation structure continues to be adopted to the specific needs of each nation. For example, price based unit commitment and optimal power flow solutions with bidding generations and loads characteristics in the present scenario are totally different compared to a regulated set up. Hence adequate exposes towards power engineering curriculum and new software tools are needed to support new activities in the modern power pools.
The power industry is moving rapidly from regulated conventional setup to a deregulated environment. There is an urgent need to keep a track of international experiences and activities taking place in this emerging field. This paper gives a bibliographical survey and general backgrounds of research and development in the field of power system wheeling under deregulated environment based on over 170 published articles. Wheeling in general and the establishment of wheeling rate in particular, are subjects of extensive debate today. This will be very much useful for all countries, especially those developing countries which are moving toward the unbundling of electricity supply industry (ESI). The collected literature have been divided into many section, so that new researchers do not face any difficulty for obtaining literature particularly in the area of wheeling of power under deregulated environment.
