独立发电商的策略报价研究

在不完全竞争的电力市场中，独立发电商往往可以通过策略报价来获得更多的利润。该文分析了机组利润、出清电量与报价策略系数之间的相互关系，从而得出了单机机组的最优报价策略和在报价越界时的优化调整方法；并提出了同一电厂不同机组间的策略组合报价模型。该文采用博弈论的方法来求解机组的报价策略系数。文中的算例说明了所提算法的有效性，其结果表明该文报价策略有利于独立发电商在市场竞争中获得最大的利润。

RESEARCH ON BIDDING STRATEGY FOR AN INDEPENDENT POWER PLANT

The emerging electricity market of imperfect competition makes it possible for each power supplier to gain more profits through strategic bidding. Through analyzing the relation between the clearing results and the coefficients of generator's bidding strategy, an optimization bidding strategy for single generator's is presented and an optimal adjusting method is obtained when generator's output exceeds its power generation limits. An iterative method is applied to clear market and get the coefficients of plant's bidding strategy. For generators belonging to the same plant, the paper puts forward an optimized and combined bidding strategy model. Some examples are used to illustrate the feasibility of the proposed method axed the results indicate that the bidding strategy of this paper can make independent power plant gain maximum profits in market competition environment.
