Abstract：Battery energy storage technology can improve the transient response of the power grid, and increase the ability to resist disturbance, which has attracted much attention. However, the traditional simulation software lacks accurate battery energy storage system component model, which affects the accuracy of analysis of energy storage system response characteristics to some extent. In this paper, an electromechanical transient model of battery energy storage system without time delay is presented, which takes into account the limitation of battery charge/discharge power and charge/discharge cycles. The model is composed of three parts, active/reactive power decoupling control, the model interfaces, and the system limitation. Based on the node current injection method, the control model is built using the comprehensive program of power system analysis. The EPRI-7 standard system is selected for simulation verification. The simulation results show that the model has good embeddedness, and its output characteristics are consistent with the theoretical analysis under given working conditions.
