Original Abstract Submitted

A power control system includes: a first energy storage system; a bidirectional AC/DC converter connected between an AC power system and the first energy storage system; and a control device for controlling an operation of the bidirectional AC/DC converter. The control device controls the operation of the bidirectional AC/DC converter to control charging and discharging of the first energy storage system. The power control system includes: a circuit breaker connected between the AC power system and the bidirectional AC/DC converter; a resistor connected between the circuit breaker and the bidirectional AC/DC converter; and a switch for forming a discharge path for discharging the DC power of the first energy storage system via the resistor, while the circuit breaker is open.
