基于进化博弈的电力市场竞价规则研究

Application of evolutionary game theroy in studying bid rules of generator’s price strategies

进化博弈理论把博弈论分析和动态进化过程结合起来,是目前经济学领域的前沿理论。应用该理论对电力市场中按报价结算和市场出清价统一结算这两种竞价规则进行比较研究,通过对发电商上网竞价的价格策略结果进行建模分析,得出在供给紧张时,应采用按出清价统一结算;在供给充裕时,应采用按报价个别结算,这样不仅能够合理调节上网价格,而且能引导发电商采取合适的竞价策略。

Evolutionary game theroy that links game theory with dynamic evolution is the frontier theory in the economic field. This paper uses the evolutionary game theroy to analyse the two different bid rules,and analyses the generator＇s price strategies in the process of bidding in a power market. It points out that it should be settled according to the market clearing price when supply tensely and according to pay-as-bidding price when supply abundant, which could not only adjust the market clearing price, but also make generators adopt suitable bid price strategies.
