POWER CONTROL METHOD, POWER CONTROL DEVICE, AND POWER CONTROL SYSTEM

摘要

A power control method in one aspect of this disclosure has the following steps: a determination step in which a control threshold for the beginning of a demand period is determined on the basis of a demand target; an update step in which, in the middle of the aforementioned demand period, the amount of power that was supplied by an external power supply and consumed by a consumer between the beginning of the demand period and a given point in time is computed and the abovementioned control threshold is updated on the basis of the computed power consumption and the abovementioned demand target; and a supply step in which, if the consumer's instantaneous power consumption exceeds the aforementioned control threshold during the aforementioned demand period, power is discharged from a distributed power supply and supplied to the consumer.
