Pcs: Power Control System
Energy Storage Converter The Power Control System (PCS) controls the charging and discharging process of the battery for AC/DC conversion.
It is possible to supply power directly to the AC load without grid.
The PCS consists of a DC/AC bidirectional converter, a control unit, and so on.
The PCS controller receives the background control command through communication, and controls the converter to charge or discharge the battery according to the symbol and size of the power command, thereby realizing the adjustment of the active power and the reactive power of the power grid.
The PCS controller communicates with the BMS through the CAN interface to obtain the battery pack status information, which can realize the protective charging and discharging of the battery and ensure the safe operation of the battery.
