Abstract:
The consumer energy management system is equipped with: an uninterrupted power supply which is charged with alternate-current input and supplies power to a load in the event of a power failure; and an uninterrupted power supply management unit for controlling interruption of the alternate-current input to the uninterrupted power supply by means of a switch and recovery from the interruption. In addition, the system is equipped with an energy management unit for, upon receipt of demand restriction information from a power grid management system, outputting a command to the uninterrupted power supply management unit to set the switch to an off state.
