Research on the Comprehensive Evaluation Index System of Power Grid Considering Energy Storage.

With the advancement of the national "dual carbon" strategic goals and the planning of new energy systems, the proportion of new energy connected to the power grid is rapidly increasing. Therefore, it is urgent to accelerate the planning and construction of energy storage, and promote the transition of the power system from "source-network-load" to "source-network-load-storage" multi entity coordinated evolution. In this context, from the perspective of energy storage as a regulatory resource, this article establishes a comprehensive evaluation index system for the power grid that fits the connotation of the new power system. The selection of indicators follows the SMART principle to ensure the application value and operability of the indicators; and uses the Analytic Hierarchy Process to calculate the weights of each indicator layer by layer. Taking the four provinces in Central China of State Grid as examples for analysis, the evaluation results of each province can be clearly quantified, among which Hunan has the highest comprehensive score. The research results of this article have certain guiding significance for the implementation and comprehensive evaluation of energy storage planning in various regional power grids.
