电力现货市场中基于发电商竞价均衡情景的市场力缓解模型与方法OA北大核心CSTPCD

With the continuous advancement of market-oriented reforms,the current electricity spot market faces the risk of market power abuse.For a unilateral bidding mechanism based on a uniform marginal clearing price(MCP)commonly used in the electricity spot market,this paper designs a market power behavior indicator and proposes the corresponding mitigation methods and mechanisms,aiming to effectively mitigate the exercise of market power and promote the consumption of a high percentage of renewable energy.Specifically,we analyze and prove the general rules for exercising market power by rational generators under the uniform MCP-based unilateral bidding mechanism and design a market power behavior(ex-post)detection indicator.Using rate-limiting measures and criteria for maximizing the welfare of consumers,two measures and mechanisms that can mitigate the market power exercised by generators are proposed.Combined with the background of the market-based consumption of renewable energy,a"simultaneous bidding,sequential clearing"joint bidding model is established.The case analysis verifies the effectiveness of the proposed method and the rationality of its application in the future electricity spot market.
