Real Time Implementation of Non-Intrusive Appliance Load Monitoring to Improve the Energy Efficiency of a Smart Home

The increase of the energy demand presents a main problem for modern buildings. The energy saving and reduction of energy consumption are the two challenges of the world. This paper consists in determining the consumption by uses in a domestic environment from the measurements taken at the level of the energy meter just downstream, using a current and voltage sensor, without a learning phase inside the residence. This so-called non-intrusive method has several advantages. It is used to process load curves and extract useful information for identifying uses, especially the most energy intensive. Also, this method helps us to review the energy management, control, metering and billing systems for our consumption, to achieve our goal of increasing energy efficiency and minimizing consumption.
