Abstract

An energy control optimization method for electrochemical energy storage to improve the transient stability of the new energy grid is studied in this paper. Firstly, the characteristics of the electrochemical energy storage system during the transient and steady-state operation of a new energy grid with an electrochemical energy storage system are studied, and the transient and steady-state operation model of the electrochemical energy storage system is established. Then, the transient energy control of electrochemical energy storage system is divided into three-layer control process, and the transient energy control method of electrochemical energy storage system is proposed. The transient energy control optimization model of electrochemical energy storage system is established with the total control cost of the system as the optimization objective, and deep reinforcement learning algorithm is used to optimize the solution of the control model. Finally, the proposed control model is analyzed and verified by building a simulation example with the data of new energy station in a certain area of Qinghai. The results show that the energy control optimization method of electrochemical energy storage system proposed in this paper has a certain effect in improving the transient stability of the new energy.
