Investigation of electrical characteristics of residential light bulbs in load modelling studies with novel similarity score method

In load modelling studies, the behaviour and electrical characteristic of a load are the main entries used in the identification of that load. This study is focused on the electrical characteristics of light bulbs (compact fluorescent light, fluorescent, incandescent, and light-emitting diode) with different characteristics that can be found in a house. While discovering these characteristics, current waveforms were used and electrical features were revealed. In addition, a novel method is proposed to identify individual loads by using these features. In this scope, a novel similarity score measure is introduced. In the presented study, similarity score measure is calculated from the total harmonic distortion, power, and harmonic current features. The experiments on randomly selected loads demonstrate that the proposed method successfully identified the loads even if they have similar characteristics or power consumption.
