市场模式下光伏用户群的电能共享与需求响应模型
Power Energy Sharing and Demand Response Model for Photovoltaic Prosumer Cluster Under Market Environment
摘要
Abstract
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 .关键词
