Power demand forecast device, method and system and power failure detection system

摘要

Disclosed herein is a power demand forecast device including: an absence detection section adapted to detect whether a consumer is absent at a given location; and a power demand forecast section adapted to forecast a power demand on a forecasted date and time in future based on an absence detection result obtained by the absence detection section.

主权项

1. A power demand forecast device comprising:
an absence detection section adapted to detect whether a consumer is absent at a given location; a power demand forecast section adapted to forecast a power demand on a forecasted date and time in future based on an absence detection result obtained by the absence detection section; a presence/absence information generation section adapted to generate presence/absence information, wherein if a presence time is greater than a given time threshold, the presence/absence information generation section generates presence/absence information indicating that the consumer is present; and a power failure determination section adapted to compare a power demand forecast of at least one electric appliance at the current date and time against the present power consumption of the electric appliance and determine whether the electric appliance is developing a power failure based on the difference between the power demand forecast and power consumption and a given threshold.
