To stabilize the power distribution system's voltage within a certain constant range. An electric-power management system wherein an area controller transmits, to each of section controllers, information about a target voltage and information about the present voltage, each of the section controllers calculating a difference between the information about the target voltage and the information about the present voltage, which the section controller has received from the area controller, and calculating a power's demand-supply-adjustment request amount based on the difference between the information about the voltages, each of facility-equipment controllers transmitting power-reception/power-release capable equipment information to each section controller, the power-reception/power-release capable equipment information being information about a power-reception/power-release capable equipment in a facility into which the facility-equipment controller is installed, the section controller, based on the power-reception/power-release capable equipment information about the equipment, transmitting the equipment's demand-supply-adjustment request amount and the facility-equipment controller transmitting a control signal to the equipment based on the equipment's demand-supply-adjustment request amount that the facility-equipment controller has received from the section controller to the facility-equipment controller in the facility into which the equipment is installed. |
