Non-intrusive load monitoring: Use of low resolution steady state features to disaggregate household appliances

This work focuses on understanding capability and limits of low resolution steady state features to disaggregate domestic appliances. Features are active and eventually reactive power with sampling period of one or few seconds. Three algorithms have been used: Hart, Weiss and EICCA - NILM algorithms. This work details results for several appliance groups. Time of occurrence has been investigated as a possible feature, exposing results and limitations.
