| 摘 要： | 电力市场是一个不完全竞争的市场,模拟这类市场成员策略使用较多的模型有古诺模型、供应函数均衡模型等。该文根据电力市场的特点,提出一种新的博弈模型来模拟发电商的策略行为,推导了该模型的纳什均衡解。最后通过算例比较了该模型与现有模型均衡解的区别,并分析了电力需求弹性和发电容量约束等因素对市场均衡状态的影响。

| Abstract: | The real electricity market is an imperfect competition market. And to simulate the strategies of suppliers, some models such as Cournot and supply function equilibrium are employed. In this paper, a new oligopolistic game model is put forward to finish the above simulation. The formulae of Nash equilibrium are obtained based on complete information. The results of Nash equilibrium of the newly presented model are compared with that of other game models,and the impacts of demand elasticity and generation capacity constraints on Nash equilibrium are analyzed. |
