摘　　要：发电侧市场竞争日益激烈,发电商需优化竞价策略,从而提高利润。在考虑剩余需求和发电能力限制的基础上,分析关键发电商竞价策略对竞争对手市场出力和利润的影响,构建了含有关键发电商的供给函数均衡模型。该模型充分考虑竞争对手的竞价策略,更客观地反映出关键发电商对市场均衡的影响。以IEEE30母线系统中4家发电商为例进行算例分析,模型结果验证了所提出方法的可行性和合理性。In the increasingly competitive generation-side power market, power suppliers need to optimize bidding strategies in order to gain more profits. Considering the residual demand and capacity constraints, this paper analyzes the impact of pivotal power suppliers＇ bidding strategies on their competitors＇ market power and profits, and establi- shes a supply function equilibrium model considering pivotal suppliers. The model takes the rivals＇ bidding strategy into account, and objectively reflects the pivotal power suppliers＇ impact on market equilibrium. Then four power sup- pliers in IEEE30 bus system exemplify the model, and the calculation results verify its feasibility and rationality.
