A device operation plan creation device of the present invention is provided with a power generation amount prediction unit (110), a power demand prediction unit (120), a hot-water supply demand prediction unit (130), an estimation unit (140), a determination unit (150), a calculation unit (161), and a plan creation unit (162). The power generation amount prediction unit (110) predicts the amount of power generation. The power demand prediction unit (120) predicts the amount of power demand. The hot-water supply demand prediction unit (130) predicts the amount of hot-water supply demand. The estimation unit (140) estimates the amount of power generated by a fuel cell on the basis of the predicted value of the amount of hot-water supply demand. The determination unit (150) determines the electricity storage amount of a storage battery. The calculation unit (161) calculates an electricity storage loss and an electricity purchase loss on the basis of the predicted value of the amount of power generation, the predicted value of the amount of power demand, and the electricity storage amount of the storage battery and calculates a balance amount obtained by subtracting the sum of the electricity storage loss and the electricity purchase loss from an electricity selling profit based on the amount of power generation. The plan creation unit (162) creates a threshold value for setting the charging or discharging operation of the storage battery and an operation plan for operating or stopping the fuel cell so as to increase the balance amount. |
