The INPPCS converter can realize AC and DC conversion between the power grid and the battery and complete the two-way energy flow between the two. It is the main actuator and core component of the energy storage system. Through advanced control strategies, the charge and discharge management of the battery system, the charge and discharge power control of the battery energy storage system, the grid-connected/off-grid operating modes and the mode switching function are realized; at the same time, it has complete protection functions, such as islanding protection, DC overvoltage protection and low voltage ride-through, etc., to meet the system connection and off-grid requirements.
