MICROGRID OPERATION DEVICE AND MICROGRID OPERATION METHOD

WIPO Patent Application WO/2018/051684

A1

Provided are a microgrid operation device and a microgrid operation method with which a large-scale stoppage of power demand devices and a stoppage of private power generation equipment can be prevented and a transition to independent operation can be performed suitably by curtailing power demand devices in advance. The microgrid operation device 10 is equipped with: a current system status prediction unit 23 that predicts the current microgrid system status on the basis of measurement data; and a control method formulation unit 27 that determines a dropout during independent operation on the basis of a dropout condition that at least includes frequency fluctuations and/or a voltage fluctuations stored for each power demand device 32 in the microgrid system, uses the frequency fluctuations and the voltage fluctuations to select a power demand device to be curtailed so as to increase the usable power, and curtails the selected power demand device before a transition to independent operation.
