Title:
POWER MANAGEMENT SYSTEM
Document Type and Number:
Japanese Patent JP2018023220
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To suppress an occurrence of a difference between supply power supplied from a power distribution system and power consumption used by consumers.SOLUTION: A power management system of one embodiment performs demand adjustment of electric power by controlling storage batteries of a first consumer group indicating a consumer group being included in total consumer groups, consuming the electric power supplied from a power distribution system, and provided with the storage batteries. The power management system comprises a calculation section and a transmission section. The calculation section calculates a command value of charge-discharge with respect to the first consumer group for each division time obtained by dividing unit time by a predetermined number based on a differential power amount between supply power provided from the power distribution system in the unit time when buying and selling of the electric power are performed and a total demand prediction power amount predicted to be consumed by the total consumer groups in the unit time. The transmission section transmits the command value of the charge-discharge to the first consumer group.SELECTED DRAWING: Figure 3
