Abstract

An independent operation detection apparatus that detects an independent operation, includes: a reactive power injection unit; a power change period detection unit; a power change period storage unit; an average power change period calculation unit; a power change period prediction unit that predicts the next power change period; a deviation calculation unit that calculates a deviation; and an active independent operation determination unit that determines whether the dispersed power source is the independent operation or not.
