Optimal Configuration of energy Storage in New Energy Stations Considering Battery Life Cycle

Abstract

In order to analyze the energy storage benefits and their impact on new energy stations throughout their entire life cycle, a new energy station energy storage optimization method considering the power supply life cycle is proposed. Firstly, based on the operational characteristics of energy storage in new energy stations, a revenue model and a cost model are established for the energy storage system; Secondly, by taking the constraints of each energy output in the new energy station into account, with the goal of maximizing investment return, an objective function is established by considering the entire life cycle of the battery, and the improved Grey wolf optimization algorithm is used to solve the objective function; Finally, the configuration of 10MW/20MWh energy storage is used as an example to verify the proposed method. The results show that the optimized new energy station has significantly improved the phenomenon of wind and light abandonment, and the net income of energy storage has been increased.
