  • Publication number: 20230275436
    Abstract: A power management server applies, when predetermined processing is applied to a power storage apparatus in all of two or more facilities, first processing to the power storage apparatus in one or more facilities included in the two or more facilities when an upper limit of adjustable power which is adjustable by controlling the power storage apparatus exceeds adjustment-requested power. The power management server applies, when the predetermined processing is applied to the power storage apparatus in all of the two or more facilities, second processing to the power storage apparatus in the one or more facilities included in the two or more facilities when a lower limit of the adjustable power falls below the adjustment-requested power. The predetermined processing is executed autonomously by the power storage apparatus. The first processing and the second processing are processing in which the controller sequentially controls the power storage apparatus.

  • Publication number: 20200252232
    Abstract: A network system includes a refrigerator, a terminal, and a server capable of communicating with the refrigerator and the terminal. The server determines a time zone in which the possibility is high that the door of the refrigerator is opened/closed by performing learning of an operation of opening/closing the door of the refrigerator. In a case where the door of the refrigerator is not opened/closed in the determined time zone, the server sends, to the terminal, information indicating that the door of the refrigerator is not opened/closed in the determined time zone.
