Title:
POWER CONTROL SYSTEM AND POWER CONTROL METHOD THEREFOR, AND POWER GATEWAY APPARATUS AND POWER CONTROL METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2012/086572
Kind Code:
A1
Abstract:
A power control system is provided with a first group of power-load apparatuses, among a plurality of power-load apparatuses, that use power supplied from a power storage apparatus when the total amount of power consumption by all of the plurality of power-load apparatuses is equal to or more than a threshold value, and a second group of power-load apparatuses that do not belong to the first group of power-load apparatuses. When the grand total of the total amount of power consumption by the second group of power-load apparatuses and the total amount of power consumption by the first group of power-load apparatuses exceeds a threshold value for the amount of consumption of power coming from a power supplying grid, a power gateway apparatus stops the power being received from the power supplying grid to supply to the first group of power-load apparatuses, and supplies power from the power storage apparatus to the first group of power-load apparatuses. The power gateway apparatus also supplies power supplied from a power generation apparatus to the first group of power-load apparatuses, more in priority than power received from the power grid.
