It is proved that only one of the parameters between slope and intercept of the bidding curve is an independent variable in order to achieve definite equilibrium. In the meantime, the equilibria of the bidding strategy about suppliers are studied when different intercepts of the bidding curve are chosen. Some examples are employed to study the Nash equilibrium strategies of suppliers with different future contracts in various bidding strategy models. The results show that the equilibria are different in different bidding strategy models, but the future contracts can effectively make spot prices decrease in all the models.1. IntroductionThe electric power industry worldwide is experiencing unprecedented restructuring from the traditional integrated regulation monopoly to a competitive power market. The object of deregulation is to introduce a competition mechanism into the power market and provide incentives for efficient operation of the power industry, eventually reducing the market price. The ideal market is a perfect competitive market in which participants bid their marginal cost into the market. Consequently, the market price is low in this kind of market. However, the electricity market is different from other merchandise 下载后可任意...
