Method to determine utility consumption of individual appliances in a household from periodic measurements of aggregate utility consumption

摘要

A method of determining the utility consumption of each appliance in a collection of appliances by using periodic measurements of aggregate utility consumption of all appliances in the collection, is disclosed. The method comprises of determining the normal utility consumption of various modes of each appliance, fixing a measurement interval, and then measuring aggregate utility consumption at periodic intervals. In each interval, we first determine if the change in aggregate utility consumption in an interval is due to change in status (ON or OFF) of one of the appliances. Otherwise we determine if the change in aggregate consumption is due to a change in status of a pair of appliances. Otherwise, we determine if change in aggregate consumption is due to change in status of a triplet of appliances.

1. A method for determining utility consumption of each appliance from a collection of appliances by measuring only aggregate utility consumption of the collection of appliances, the method comprising of:
(a) determining utility consumption of various modes of each appliance, (b) determining a periodic measurement interval, and measuring the aggregate utility consumption at the periodic interval, (c) first determining if a change in aggregate utility consumption in an interval is due to change in status (ON or OFF) of one of the collection of appliances, otherwise (d) then determining if the change in aggregate consumption is due to a change in state of a pair of appliances, otherwise (e) then determining if change in aggregate consumption is due to change in state of a triplet of appliances, and (f) determining total utility consumption of a specific appliance from the collection of appliances from the utility consumption of the specific appliance in each measurement interval.
