DEMAND POWER LEVELING SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a system for leveling demand power in nighttime power by using power amount data measured by a smart meter.SOLUTION: A demand power leveling system comprises: a smart meter 7 which measures a whole usage power amount in a user 4 used by a calorifier 6 and general electrical apparatus 5, and transmits data on the power amount to a remote site through communication means 9; and a computer 10 which comprises a database 11 for storing the power amount data and performs predetermined arithmetic processing by using the power amount data. The calorifier having power control means 6A is configured so as to be capable of adjusting a usage power amount. The computer levels the whole usage power amount in a night time zone by: calculating a general load usage power amount by subtracting a usage power amount of the calorifier from a whole usage power amount between a use start time point and a use end time point of the calorifier; and proportionally dividing a heavy load usage power amount depending on difference between a set usage power amount set in advance and the general load usage power amount so that a heavy load usage period is within the night time zone.
