Identifying fridge consumption in supervised global electric consumption

In a domestic context, NILM applications (Non-Intrusive Load Monitoring) are of big interest. Indeed, it allows users to know their electric consumption without having to install lots of sensors in theirs houses. The freezer and fridge consumption represents approximately 10 to 15 % of global domestic electric consumption in Belgium. The aim of this paper is to present a new method for the identification of fridges based on transient power patterns. Results of the study rely on supervised data obtained by sub-metering at the level of an appliance for two real domestic houses.
