摘　　要：随着电力体制改革不断完善,发电商市场竞争日益激烈,为在激烈的电力市场中获得最大收益,发电商需采取合理有效的竞价策略。在考虑容量约束和主要发电商两因素的基础上,分析了分界价格与利润之间的关系,建立了分段供给函数均衡模型。该模型更客观地反映了发电商的市场潜力,并为之提供有效的竞争策略。以某区域电力市场中的6个发电商为例进行算例分析,模型结果验证了本文所提出方法的合理性和可行性。Power gencos need to take reasonable and effective bidding strategies in order to gain maximum benefit in the increasingly competitive electricity market.Considering the capacity constraints and the major power producers,this paper analyzes the relationship between the boundary price and profit,and establishes a segmented supply function equilibrium model.The model reflects the gencos′ market potential,and provides an effective competitive strategy.To illustrate the model,six power suppliers in a regional electricity market have been calculated and analyzed,and the calculation results show that the proposed method is reasonable and feasible.
