The Research Of Reservoir Power Generation Optimized Operation And Early Warning Mechanism Layered Coupling Model Based On Power Market

Hydropower resources is very rich in our country, giving priority to the development of hydropower is China's most important energy and environmental strategy. The utilization and development of water resources have a huge role to the development of the national economy and improving the people's living standards. With the "factory nets separate, bidding for access", our country's electric power market is gradually established. At the time of hydropower is developing, we must recognize that electric power market is lack of stable hydropower effectively in energy efficient operating mechanism, there's a long way to go. Therefore, launching research of reservoir power optimization scheduling under the background of electric power market, further perfecting theory and researching the new methods and new technology have important applications and academic value.This paper firstly expounded the station of hydropower optimum operation under the market environment and the background and the domestic and foreign research present situation, then union power market reforms, formulated the reservoir power dispatching operation rules line and hydropower station was studied in electricity generation plan, determination of hydropower electricity and months contract, on the basis of decomposition, introducing the warning mechanism of market environment in contract if counld complete power hydropower and complete degree and launched research and discussion of strain measures, made the following main research results:(1) Reservoir power dispatching operation rules formulated line. With the most power benefit as the objective function by applying stochastic dynamic programming model calculation results, formulated the geheyan reservoir hair, and scheduling operating rules line, using this operation rules line conducted a long series of simulation calculation, Comparison analysis are made with the calculated results of dynamic programming, show that the operating rules line has reasonableness and reliability.(2)Years generation plan. Based on simulated hydropower adsense series elevates the calculation of generating scheduling based on hydropower station capacity, statistical characteristic, history to determine the annual contract of hydropower electricity the power within the annual contract, on the basis of decomposition, with the objective of maximizing benefits and the particle swarm algorithm, formulate the hydropower years generating plan.(3)Establish power dispatching warning decision system. To ensure the hydropower station power be finished, avoid economic sanctions by grid, based on the reservoir scheduling operating rules line and hydropower power plans, and introducing early warning mechanism, combining of the present situation, considering the future water for months, warning analysis was carried out under the different degree of contract is completed in hydrological, established the reservoir power dispatching warning decision system, Expect to be able to early predict power complete degree, and contract formulated the corresponding measures, it have a certain reference value to policymakers in actual operation and reservoir reservoir long-term scheduling, at the same time, in the process of dispatching decision-making, reflected the decision maker's preferences trend and risk of different interests.
