Abstract

The state estimation method for conventional consumer electronics goods that do not have network capabilities is presented. The purpose of the research is to save home electricity consumption and to adjust electricity consumption amount with electricity generation by prevailing home energy management system (HEMS). The method consists of 2 parts, one is to classify the home appliances by harmonics component included in the electricity current, and the other is ON/OFF decision making tool by Wavelet analysis. The both technology can be applied to HEMS and estimate the state of the home appliances without additional network in home. The state includes ON/OFF switching, electricity consumption rate and so on.
