Construction method of virtual power plant based on optimized aggregation of prosumer resources

Abstract

Virtual power plant (VPP) can aggregate prosumers clusters of prosumers into a whole to participate in power grid dispatching and power trading. This paper proposes to aggregate prosumers in the same distribution station area to form a VPP. Its operators signed bilateral power contracts with DSO and prosumers day-ahead, then organize power generation resources and achieve the customized construction of VPP in accordance with the output requirements of the contract. Constrained by the output requirements of VPP, the Stackelberg game is used to model the transaction negotiation process between VPP operators and prosumers, and the conditional value at risk is used to measure the potential risk loss caused by various uncertain factors in the construction of VPP, thereby forming a customized construction method of VPP. The results of the case study show that the method proposed in this paper can promote the local consumption of new energy, and realize the mutual benefit between VPP operators and prosumers.
