摘　　要：能源互联网背景下,能源供需市场呈现更为显著的智能化和开放性,同时供电主体也逐步呈现多元化、竞争化态势。针对开放性市场环境下多个供电主体竞争并存的格局,分析了单个供电主体与其他供电主体的竞争互动问题,基于势博弈理论构建了多供电主体间的竞争博弈模型。同时,设计了动态互动电价,刺激用户与供电主体间的供需互动,形成以用户需求为中心、以市场为导向、以满意度最大化为目标的电力营销策略。算例分析结果说明了竞争模型的建立可帮助供电主体定价营销策略更加理性,同时也实现了对用户侧可控资源的高效利用。Under the environment of energy internet,the power supply-demand market presents a more remarkable trend of smartness and openness.Meanwhile,the power suppliers also face a more diversified and competitive situation.Considering the competition and coexistence of multiple power suppliers in the open market environment,this paper analyzes the competitive behavior and interaction between single power supply entity and others different entities,and formulates the competitive game model among them based on a potential game.Meanwhile,a dynamic interactive electricity pricing strategy is designed to stimulate the interaction between users and power suppliers,with the goal of users-centered,market-oriented,maximizing satisfaction of market main bodies.Simulation results demonstrate that the proposed competitive model can help power suppliers to be more rational,and also can realize the efficient utilization of user-side controllable resources.
