POWER DEMAND CONTROL DEVICE, POWER DEMAND CONTROL METHOD, POWER DEMAND CONTROL SYSTEM, PROGRAM, AND RECORDING MEDIUM

摘要

In a power demand control system (100), when the ratio of the total time in a non-operating state of a press machine (3) within a certain time interval with respect to the total time in an operating state of the press machine (3) within the certain time interval is higher than a predetermined threshold value, the press machine (3) is placed under power demand control. This can mitigate the reduction of the production efficiency and the deterioration of the environment in a facility in which devices are arranged depending on power demands.
