Non-Cooperative Game-based Coordination Control of Multiple Virtual Power Plants

Virtual power plant (VPP) can effectively control multiple kinds of distributed energy resources (DERs) in different geographical locations. Given that VPPs may belong to different owners and beneficiaries, this study proposes a non-cooperative game-based coordination control (NCGCC) method for the VPPs. In the method, the NCGCC is proposed to coordinate adjustable photovoltaic (PV) power resources, energy storage and other DERs to reduce the total generation cost within the VPP. The cost models of different beneficiaries are established to consider the economic benefits of each VPP, and the NCGCC among the VPPs is used to solve the competition problem among VPPs. Each VPP bids to undertake power generation tasks in order to minimize the cost. Finally, the simulation results of typical multi-VPP system under various operating conditions are compared and analyzed to verify the effectiveness and applicability of the proposed method.
