The electrochemical energy storage power station is the key link in new energy construction, and the coordination controller is the core secondary equipment to ensure the safe and reliable operation of the electrochemical energy storage power station. Given the difficulties in dynamic simulation testing of the coordination controller, this paper analyzes the coordination controller and its control strategy, the characteristics of battery management system (BMS) and power conversion system (PCS), and the GOOSE data interaction. Through research on the simulation method of BMS and PCS characteristics, a hierarchical modeling technology for multiple BMSs and PCSs is proposed. According to the requirements of model calculation and data interaction, a real-time simulation method and a GOOSE data sending and receiving mechanism are developed. A hardware-in-the-loop environment of the real-time simulation system is built, a dynamic simulation test scheme is formulated and a complete dynamic simulation test is finished. The real-time operation of the model and the dynamic simulation test proved the feasibility of the dynamic simulation test technology for the coordinated controller.
