  • Patent number: 12212141
    Abstract: A power conversion device inputs or outputs a power for changing a state quantity of a distribution grid to which a voltage source device is connected, to or from the distribution grid. A grid control unit calculates a power command value of the power conversion device such that a drooping characteristic is provided for compensating for a deviation from a control target of the state quantity obtained from an output of a detector. A frequency characteristic of control computation for calculating a power command value from the deviation in the system control unit is defined such that a first control gain value in a first frequency range including direct current is set corresponding to a slope of the drooping characteristic, and a second control gain value in a second frequency range including higher frequencies than the first frequency range is set to be lower than the first control gain value.
