Abstract
A current suppression control unit calculates a correction amount of a reference voltage command value for operating a power converter as a voltage source, and sets an amplitude value of a voltage command value by reflecting the correction amount in an amplitude value of the reference voltage command value. The correction amount is set to make the amplitude value of the voltage command value smaller than the amplitude value of the reference voltage command value, in response to a decrease in an AC voltage at an interconnection point.
