Different appliance identification methods in non-intrusive appliance load monitoring

Abstract

The aim of appliance identification methods is to get electrical energy consumption at appliance level based on aggregate measurements from a single energy meter. The appliance identification methods in conjunction with smart meters provide consumers with detailed statistics of electrical energy consumption. The detailed feedback could lead to a reduction in energy consumption, including increased consumer awareness. In this paper we describe electrical parameters and appliance groups with different electrical behaviors. We review different steady and transient state identification methods. Then we compare requirements and limitations of discussed methods.
