An Optimal Scheduling Method of Virtual Power Plant Cluster Considering Generation-grid-load-storage Coordination

How to consider the cooperative and complementary capabilities of ‘generation-grid-load-storage’ to optimize the scheduling of virtual power plant clusters (VPPC) is an urgent problem need to be solved to improve the operating economy and clean energy consumption capacity of the distribution network under the jurisdiction of VPPC. This paper proposes an optimal scheduling method of VPPC considering generation-grid-load-storage coordination. Firstly, the basic operation structure of VPPC is constructed. Various resource models of generation-grid-load-storage within VPP are established. Secondly, a two-stage optimal scheduling model of VPPC considering the coordination of generation, grid, load and storage is established. Finally, based on the improved IEEE 33node power distribution system, a VPPC with 5 VPPs is constructed for simulation. The results show that the method proposed in this paper is conducive to reducing the operating cost of the system and improving the consumption of clean energy under the environment of transaction access constraints.
