Power control system and power control method therefor, and power gateway apparatus and power control method therefor

摘要

First power load apparatuses that use power from a power storage apparatus when a total power consumption amount of all of the plurality of power load apparatuses is greater than or equal to a threshold, and second power load apparatuses not included among the first power load apparatuses are included. A power gateway apparatus stops the supply of power from a power supply system to the first power load apparatuses and performs power supply from the power storage apparatus to the first power load apparatuses when a sum of a total power consumption amount of the second power load apparatuses and a total power consumption amount of the first power load apparatuses exceeds a threshold indicating a maximum value of the system power consumption amount. The power gateway apparatus supplies power from the power generation apparatus to the first power load apparatuses with priority to power from the power network.

1. A power control system including, among a plurality of power load apparatuses, first power load apparatuses that use power supplied from a power storage apparatus when a total power consumption amount of all of the plurality of power load apparatuses is greater than or equal to a threshold, and second power load apparatuses not included among the first power load apparatuses, wherein the power control system includes a power gateway apparatus comprising:
a second power load apparatus consumption amount reception unit that receives a total power consumption amount of the second power load apparatuses from a power consumption amount detection device that detects power consumption amounts of the second power load apparatuses; a first power load apparatus consumption amount detection unit that detects power consumption amounts of the first power load apparatuses to detect a total power consumption amount of the first power load apparatuses; a total power consumption amount determination unit that determines whether a sum of the total power consumption amount of the second power load apparatuses and the total power consumption amount of the first power load apparatuses exceeds a threshold of the system power consumption amount; and a power supply control unit that stops supply of power received from a power supply system to the first power load apparatuses and performs power supply from the power storage apparatus to the first power load apparatuses when the sum of the total power consumption amount of the second power load apparatuses and the total power consumption amount of the first power load apparatuses exceeds a threshold indicating a maximum value of the system power consumption amount.
