  • Publication number: 20250105633
    Abstract: The purpose is to perform control so that a sufficient amount of stored power is secured when a DR request signal is received. A HEMS 100 is a power control device, which is a power control device that controls a storage battery 400 for supplying power to a communication device 500 that is a load device. In the HEMS 100, a DR activation prediction unit 103 predicts the activation of a demand response. A charge/discharge determination unit 108, which is a control unit, performs discharge control on the storage battery 400 based on this activation prediction. The charge/discharge determination unit 108 changes the discharge timing of the storage battery 400 depending on whether or not the activation of a demand response is predicted.
