Recurrence Plot Analysis for characterization of appliance load signature

In this paper we propose a new approach for characterization of home appliances load signature (electrical fingerprint) from Recurrence Plot Analysis (RPA) perspective, with the goal of non-intrusive appliance load monitoring (NIALM), promoted as enabling technology to save energy consumption and to lower consumers electrical bills. In our research work, RPA is adopted as an analysis tool of non-linear load current waveform in phase space and it is considered as innovative signal processing method alongside the traditional time and frequency based methods.
