    Abstract: A power management method receives, from a meter that measures the amount of surplus power, which is power supplied from a power generation apparatus to a power system, a surplus power value indicating the amount of surplus power, receives, from a first communication terminal used by a user corresponding to first user identification information, an inquiry about power supply in which the surplus power is used in a first time period that lasts a certain unit time, the inquiry being associated with the first user identification information, issues, in accordance with the inquiry, first power identification information for validating power supply performed by a power supply apparatus using the surplus power corresponding to the first time period for an accumulated value of the amount of surplus power corresponding to the first time period, transmits the first power identification information and the accumulated value of the amount of surplus power corresponding to the first time period to the first communication terminal, and causes the power supply apparatus that has received a first power supply request, which is associated with the first power identification information, indicating that power is to be supplied to the first load apparatus to supply an amount of first power equal to or smaller than the amount of surplus power to the first load apparatus as power that does not cause a charging process.

    Abstract: A power saving control device includes: an acquirer that acquires a power saving request; and a controller that determines whether or not power saving control for reducing a power consumption of a load device is to be performed in response to the power saving request, and that, when determining that the power saving control is to be performed, performs the power saving control. When the load device consumes power, the controller determines that the power saving control is not to be performed under a condition that no power flows from a power system into a facility in which the load device is installed, the condition being one of one or more conditions.

    Abstract: A power flow control system controls power flow in a first power network shared by customer facilities. The first power network is shared by a customer facility group that includes first customer facilities each including at least a load device and a power generator, and second customer facilities each including at least a load device and an electric storage device. Each of measurement devices measures, for each unit time period, electric power consumed by a load device and electric power generated by a power generator. A management device instructs timings of charging and discharging of the electric storage devices in the customer facility group such that the power flow at a connection node between the first power network and a second power network transmitting electric power from a power plant to the first power network satisfies a predetermined constraint condition using data on electric power acquired from the measurement devices.

    Abstract: A charge/discharge control apparatus includes: a controller which performs a discharge control to discharge a rechargeable battery and a charge control to charge the rechargeable battery using excess power which is power, among generated power, which is not to be consumed by a load; and a setter which sets a threshold value for remaining energy in the rechargeable battery, according to a planned discharged energy amount which is planned as a discharged energy amount to be supplied from the rechargeable battery to the load during a specified time period. The controller performs a discharge prohibition control to prohibit a discharge of the rechargeable battery when the remaining energy in the rechargeable battery is equal to or below the threshold value prior to the specified time period.
