上网竞价策略的供给函数均衡分析

Analysis of bidding strategies of suppliers based on supply function equilibrium

电力市场是一个不完全竞争的寡头垄断市场,研究竞价策略对发电商非常重要。市场中的独立发电商往往会采用合理的竞价策略来获得最大收益。该文根据联营模式下电力市场的特点,利用供给函数模型来模拟发电商的策略行为,给出了市场均衡解。此外,还分析了分段报价、需求弹性等因素对发电商均衡策略的影响。仿真算例说明了该方法的合理性和可操作性。

The electricity market is an oligopolistic competition market. Consequently, the bidding strategy is very important to the suppliers. Usually, the suppliers try to gain maximal profit by developing their best bidding strategy in the electricity market. In this paper, supply function model is employed to simulate bidding strategy of suppliers in power pool. The equilibrium equations are proposed when different bidding parameters are selected to maximize profits of suppliers, and the block bidding and power demand elasticity are also considered. The simulation results show that the method is feasible and efficient.
