Power management method, power management system, and power supply apparatus
First Claim
1. A power management method used in a power management system including a power generation apparatus corresponding to first user identification information, a first load apparatus used by a user corresponding to the first user identification information, and a power supply apparatus capable of supplying power to the first load apparatus and installed in a place different from a place where the power generation apparatus is installed, the method comprising:
- receiving, from a meter that measures amount of surplus power, which is, in power generated by the power generation apparatus, power supplied from the power generation apparatus to a power system, a surplus power value indicating the amount of surplus power;
receiving, from a first communication terminal used by the user corresponding to the 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;
issuing, in accordance with the inquiry, first power identification information for validating power supply performed by the 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;
transmitting 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
causing 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 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.
