Power management device

Abstract

The power management device includes a processor that functions to manage power exchange in a power system including a virtual power plant, and the processor includes a processor that, when an abnormality occurs in the power system and a cause of the abnormality is a voltage abnormality, causes the virtual power plant to exchange electric power only in one direction for suppressing the power abnormality, and when the cause of the abnormality is a frequency abnormality, causes the virtual power plant to exchange electric power within a range in which the output variation is equal to or less than a predetermined value, and prohibits the exchange of electric power by the virtual power plant until recovery when the cause of the abnormality is a disconnection failure or a short-circuit failure.
