Abstract

In view of the problems of insufficient flexible regulation capacity and unreasonable utilization of energy storage in parks with high renewable energy penetration, the distributionally robust optimal configuration method of shared energy storage in the park for distributed resource cluster regulation is proposed by considering the interaction of carbon quota and the uncertainty of source-load. First, we establish the distributed resource scheduling clusters in the park by considering the source-load matching degree, and generate source-load typical scenarios based on the optimal clustering model to characterize the uncertainty of the source and load power. Next, the shared energy storage flexible regulation model for distributed resource clusters in the park is established with the dynamic allocation mechanism of shared energy storage power and capacity. Then, this paper constructs a distributionally robust optimal configuration method of shared energy storage in the park based on the park cluster carbon quota and power interactions, which minimizes the sum of the annual average investment cost of energy storage and the operating cost of the park to improve energy storage utilization. Last, a typical high proportion of photovoltaic penetration park is used to verify the effectiveness of the proposed shared energy storage configuration method in dealing with the uncertainty of source-load and improving the operation efficiency of the park.
