Occupancy Detection Based on Electricity Consumption

Abstract

This article presents a new methodology for extracting intervals when a home is vacant from low-frequency electricity consumption data. The approach combines multiple algorithms, including change point detection, classification, period detection, and periodic spikes retrieval. It shows encouraging results on both simulated and real consumption curves. This approach offers practical insights for optimizing energy use and holds potential benefits for residential consumers and utility companies in terms of energy cost reduction and sustainability. Further research is needed to enhance its applicability in diverse settings and with larger datasets.
