Abstract

Regarding an independent system, a prediction value of charged/discharged power of a storage battery is calculated, based on a prediction value of generated power of a renewable energy power generator, a prediction value of demanded power of a control device, and a prediction value of demanded power of a load on an assumption that a power supply limit is applied to the load. Whether or not charge or discharge of the storage battery with charged/discharged power matching the prediction value of the charged/discharged power of the storage battery is possible is determined. The power supply limit is tightened when it is determined that the charge or discharge of the storage battery is not possible. A limit data indicating a detail of the power supply limit is output when it is determined that the charge or discharge of the storage battery is possible.
