Theory And Application Of Electric Power Market Regulation After Restructure

Recent years, China carried on the electric power market reform, which seprated the generation sector and power grid sector, the generation plantes bid for access, constructed regional markets. The reform aimed at breaking the monopoly situation of electricity industry and introducing competion into generation sector, and separation the property right of different electricity sectors, creating the market incentive mechanism to promote the electricity industry sustainable development. After the restructure, many new questions appears which need to be solved, in which, the issue of market regulation is an important question. Study the electric power market regulation in the environment of deregulation, not only has important theories meaning with the academic value, but also has the important applied value and profound realistic meaning. The thesis roundly studied the regulation issue after deregulation from the electricity industry's two most important sectors, generation sector and transmission-distribution sector.First, the thesis summarized the research of electricity market regulation, clarified the basic concept of market regulation, and analyzed the difference between the traditional vertical integrated management system and the power market. Based on the above analysis, the exercise form of market power and the primary factor that influences market power were studied.Second, the thesis summarized the current measurement indexes of market power and made division of indexes, gave the market simulationthe measurement method of generation companies' market power based on optimal power flow. This method transferred the measurement of generation companies' market power to optimal power flow. This paper also set forth the specific resolution method and validated it through an example. The ultimate object of the research of market power is to restrain, effectively monitor and control the market power of generation companies.The thesis expanded the research field of monitor and control of market power into four levels: 1, whether the generation companies own the market power and the intension of market power; 2, whether the generation companies exert the marker power; 3, the damage of the exertion of market power by the generation companies to market operation; 4, how to effectively restrain market power of generation companies. Based on such research this paper gives the specific measures of restrain of generation companies.The government still carries out goventment regution to transmission-distribution sector after deregulation for the "the network characteristic". The thesis analyzed several price regulation methods current used, and pointed out the questions of the price regulation method based on sevice-cost or rate of investment return and the other price regulation method based on performance. Considering the monopoly characteristic of transmission-distribution sector, a new price regulation method, ALTIC, based on performance was put forward, and the corresponding mathematical model was established.At the end, considing the practice of China's regional power market reform, the thesis summarized the regional power market construction situation based on the theory study and anylized problem existed in regional power market construction. A system of power market regulation evaluation index was given to assess the power market, and applied to some regional powr maket. The result showed that the system was able to reflect the concentration rate of power market, trade situation, participants biding stategy and economic efficentcy of power market.
