Abstract
An electric power converter for being electrically connected to a commercial power system of alternating current type and electrically connected to a device configured to input and/or output electric power. The converter includes a control unit configured to perform primary control of the device based on a reference function which has drooping characteristic for generating target value when local-control of the device is implemented according to voltage measured by the electric power converter. The electric power converter is further controlled according to secondary control in which the reference function having the drooping characteristic is updated according to electric power status of an electric power system in which the electric power converter is installed, and control cycle of the primary control is different from control cycle of the secondary control.
