在光伏上网电价低于市电电价的环境下，光伏用户通过集群的方式实现电能共享，可以获得比单独运行更好的效益。为了使光伏用户群内各经济主体能实现有序的电能交易，提出了一种基于光伏电能供需比（SDR）的内部价格模型。在考虑经济性和舒适度的基础上，提出了用户参与需求响应（DR）的效用成本模型。由于内部电价是以各时段光伏用户群内的供需比为基础，用户之间针对电价的需求响应行为可构成非合作博弈，在证明该博弈问题存在纳什均衡解的基础上，提出了分布式优化算法对用户的纳什均衡策略进行求解。最后，通过实际算例验证了所提模型在减少用电成本、提高光功率互用水平上的有效性。%In the environment of discrimination in the feed‐in tariff , the joint operation in cluster of photovoltaic ( PV ) prosumers could be more beneficial than the independent operation . In order to enable multi economic entities trade inside the cluster , a day‐ahead pricing model based on supply and demand ratio ( SDR) of shared PV energy is proposed . Considering the factors of economy and comfort , an effective cost model of the PV prosumers is proposed , which enables the PV prosumers participate in the demand response (DR) . As the internal prices are coupled with total power demand and supply in the cluster , the DR action of PV prosumers are formulated as a non‐cooperative game . The existence of Nash equilibrium is proved , and a distributed optimization algorithm is designed to solve the Nash equilibrium strategy . Finally , via a practical example , the effectiveness of these models is verified in terms of saving PV prosumers costs and improves the sharing of the PV power .
