Title:
POWER MANAGEMENT SYSTEM AND POWER MANAGEMENT METHOD
Document Type and Number:
WIPO Patent Application WO/2024/095374
Kind Code:
A1
Abstract:
A processor according to the present invention calculates a power consumption integrated value at a demand time limit on the basis of measured values of a power meter, and executes demand control to control electrical equipment inside a consumer facility such that the power consumption integrated value at the demand time limit does not exceed a target power. During the demand control, the processor executes normal operation of the electrical equipment from the start point of the demand time limit. The processor determines whether the comfort of the user of the consumer facility has returned on the basis of a change over time of the power consumption integrated value when executing the normal operation. The processor sets the execution time of the normal operation so as to ensure a time required in order to calculate a baseline, which is a predicted value of the power consumption integrated value if the normal operation is executed in the entire time of the demand time limit from the time at which the comfort has returned. The processor transitions from the normal operation to an energy saving operation for suppressing power consumption of the electrical equipment more than the normal operation when the baseline exceeds the target power by the end point of the demand time limit.
