Development and Application of Energy Management System for Unattended Large-Scale Energy Storage Power Station

Through the research on the system architecture and control strategy of large-scale energy storage power station at the current typical grid side, the urgent needs of unattended energy storage power station are analyzed, and a regional system architecture and multi-dimensional collaborative control method suitable for unattended energy storage power station are proposed. Based on the safety analysis of the detailed data of unit energy storage, the safety early warning architecture and control logic based on battery management system, power conversion system and energy management system are proposed to provide guarantee for the safe operation of the energy storage power station. Finally, the unattended energy management system of energy storage power station is developed, and the engineering feasibility of unmanned control in an energy storage power station was verified.
