假定竞争对手的报价策略变量服从某种经验分布,基于贝叶斯博弈原理,运用次序统计量方法,分别对电力需求确定与不确定情况下的发电公司竞价构造了博弈模型,并通过模型的求解与分析,给出了发电公司的均衡报价策略;最后对由5个发电商组成的电力竞价市场进行了算例分析,结果表明:发电商的均衡报价要么接近报价上限,要么在较低价格水平上随成本呈正向变动. Assuming that competitors’ bidding strategy variables are subject to some kind of empirical distribution, a game model based on Bayesian game theory and ordinal statistic method is used to determine the bidding prices of generation companies in the case of uncertain electricity demand and uncertainty. The model is solved In the end, a case study of electricity bidding market composed of five generators is conducted. The results show that the equilibrium bidding of generators is either close to quotation quotation or lower price level With the cost of a positive change.
