Power conversion device and power conversion system including a power converter capable of converting between alternating-current (AC) power and direct-current (DC) power
A power conversion system includes a first power converter and a second power converter which are capable of converting an alternating-current power into a direct-current power or converting a DC power into an AC power. The first power converter is interconnectable to a first AC system via a first AC circuit breaker. The second power converter is interconnectable to a second AC system via a second AC circuit breaker. A first DC terminal of the first power converter and a second DC terminal of the second power converter are connectable. The first power converter begins operation prior to the second power converter. A first control device controls a voltage of the first DC terminal, based on a status of the second power converter sent from a second control device.
