Abstract

Disclosed herein are signal identification methods and systems. In some examples, the method and/or system allows appliances to be associated with their electrical usage. In one example, a method for determining whether a load is in a steady state or in transition includes analyzing a time series of electric power or current measurements on at least one circuit, at least one load coupled to the at least one circuit; and determining whether the load is in a steady state or a transition. Also disclosed is an appliance identification method. Further disclosed is a method of mapping unlabeled appliances which utilizes a STEC Table which summarizes linkages between transitions and steady state clusters.
