This paper discusses the evaluation of flexibility in multi-point distributed energy storage systems. It deeply analyzes the definition and connotation of flexibility in the power system, proposes an evaluation index and method for flexibility in multi-point distributed energy storage systems considering the aggregation effect, and verifies the applicability and effectiveness of the method through a case analysis of the Shandong power grid-side energy storage demonstration project. The study shows that the evaluation index and method considering the aggregation effect can effectively quantify the flexible regulation ability of multi-point distributed energy storage systems in response to uncertain changes in the system. The study in this paper can help improve the quantitative decision-making level of energy storage station scheduling and operation, and has certain practical engineering value.
