Non-Intrusive Load Monitoring by Novel Neuro-Fuzzy Classification Considering Uncertainties

In contrast with a centralized Home Energy Management System, a Non-intrusive Load Monitoring (NILM) system as an energy audit identifies power-intensive household appliances non-intrusively. In this paper, an NILM system with a novel hybrid classification technique is proposed. The novel hybrid classification technique integrates Fuzzy C-Means clustering-piloting Particle Swarm Optimization with Neuro-Fuzzy Classification considering uncertainties. In reality, household appliances or operation combinations of household appliances in a house field may be identified under similar electrical signatures. The ambiguities on electrical signatures extracted for load identification exist. As a result, the Fuzzy Logic theory is conducted. The ambiguities are addressed by the proposed novel hybrid classification technique for load identification. The proposed NILM system is examined in real lab and house environments with uncertainties. As confirmed in this paper, the proposed approach is feasible.
