Distributed energy storage planning method considering the comprehensive value of energy storage

Abstract

With the massive access to distributed power supply, the power grid is facing great pressure. Distributed energy storage becomes an effective method to solve this problem. With the deepening of the electric power system reform, the existing energy storage value evaluation system and scene application have been limited. Based on the reliability value, this paper further considers the influence of distributed energy storage on power grid planning and analyzes the role of distributed energy storage in delaying the expansion plan of the transmission network and alleviating congestion. Based on the reliability value, transmission and distribution value, and energy value, a comprehensive value evaluation system of distributed energy storage is constructed, and a distributed energy storage planning model based on comprehensive value is proposed.
