电力市场环境下储能电站和光伏电站合作博弈模型

Cooperative game model of energy storage power station and photovoltaic power station in power market environment

与传统电力市场主体不同,储能电站既可以参与发电侧,也可以参与用户侧,进而获取利益。文章以发电商、售电公司、用户、储能电站和光伏电站为市场主体,建立电力市场博弈模型;以储能电站在某一时段的运行方式和报价作为博弈策略,计及储能电站必要的运行约束条件,建立储能电站运行模型;基于招标电价制建立光伏电站运行模型。考虑储能电站与光伏电站进行合作博弈,以最大化联盟收益为剩余博弈支付,以联盟内部交换功率和交易电价为协议,基于Shapley值对合作博弈剩余进行分配,通过分析得到模型的Nash均衡。文章通过算例验证了所提出方法的正确性和有效性,所建立的模型适用于储能电站与光伏电站进行合作博弈参与电力市场的情景。

Different from the traditional power market participants,energy storage power stations can participate in both generation side and user side to obtain benefits.The game model of electricity market was established with generation companies,electricity retail companies,users,energy storage power stations and photovoltaic power stations as the market subjects.Taking the operation mode and quotation strategy of energy storage power station in a certain period as game strategy,considering the necessary operation constraints of energy storage power station,the operation model of energy storage power station was established,while the operation model of photovoltaic power station was established based on bidding price mechanism.Considering the cooperative game between energy storage power station and photovoltaic power station,the Nash equilibrium of the model was obtained by maximizing the alliance revenue as the residual game payment,using the exchange power and transaction price as the agreement,and allocating the residual of the cooperative game based on Shapley value.Finally,an example was given to verify the correctness and validity of the proposed method,which is suitable for the case of cooperative game between energy storage plants and photovoltaic plants participating in the electricity market.
