Research On The Operation And Management Of Hydroelectric Plant Under The Mode Of Power Market

With the establishment and perfection of social market economy system of our country, it has already been a great trend for electric industry to break monopoly and introduce competition. The opening of power plant for power-generation will be an important step in the reform of power system in our country, which will have great influence on the operation and management of hydroelectric plant. Therefore, as to fully utilize of water resources and promote the economic benefits of hydroelectric plant, it is of important theoretical sense and practical value to research on the optimized operation and management of hydroelectric plant under the mode of power market. In this paper, researches on this are developed and the results of several aspects are obtained as follows: (I) First, analysis and sum-up about the modes of foreign power plant and their characteristics are carried out, two typical modes and four fundamental stages of market development are generalized. Based on this, power market mode accommodating to our country's practical situations is discussed, which provides a theoretical basis for researches on the operation and management of hydroelectric plant under the conditions of market economy. (2) To tailor to the demand of power futures and spot transactions under the mode of po~4er plant, the forecasting model of futures electricity capacity taking account of the indicators of macroscopic national economy is raised in this paper, which includes: AR(1), GM(l,l), LR. ANN; in addition, marginal electricity price forecasting mode of spot transactions considering the market factors is also put forward, which acquires better effects than simple timeliness serial models do. (3) Compared with the background of planning economy, the optimized operation of hydroelectric plant on the condition of power market considers not only the water supply, but also the factor of electricity price, connecting with the demand of market. In this paper, economic operation model of stage hydroelectric plant having the maximal economy benefits as its goal is put forward and field researches are carried out, which obtain better effects of application. (4) According to the operating principles of power market for power generation, a bidding decision-making support system of power plant based on Windows and WindowNT is developed, which has market forecasting techniques, bidding strategies, the economy operating theories and the modem computer technologies as its basis. It has a promising market perspective in supplying auxiliary decision-making support services in the operation of power plant.
