METHOD FOR NON-INTRUSIVE DETERMINING A POWER CONSUMPTION FOR A PLURALITY OF APPLIANCES, CORRESPONDING ELECTRONIC DEVICE, SYSTEM, COMPUTER READABLE PROGRAM PRODUCT AND COMPUTER READABLE STORAGE MEDIUM

摘要

A non-intrusive method and corresponding apparatus, system for determining a power consumption for a plurality of appliances comprises measuring aggregate power consumption of the plurality of appliances during a time interval P for N sliding windows of a duration M and a temporal distance D between successive sliding windows; selecting a number Q sliding windows from the N sliding windows according to a selection criterion for selecting sliding windows with a sum S of power consumption representative for a power consumption layer defined according to appliance use; and calculating an average power consumption per power consumption layer over the time interval P, based on the aggregate power consumption measured over the time interval P for the Q selected sliding windows.
