Energy meters provide valuable information that can be used to determine important features such as energy
consumption of electrical devices and consumption habits in corporate, residential or public institutions. This
information is crucial to establish energy saving strategies. With this aim, different approaches have been
proposed in the literature, including non-intrusive load monitoring techniques, which enable the energy
disaggregation of appliances and devices through a centralized measurement taken at panel level using
a metering infrastructure. Generally, the accuracy of these techniques increases as more information is
available on the analyzed signals or through subsequent post-computed values. Active power, reactive power,
or even current harmonics measurements can be used for this task. However, the use of these and other
recently proposed power and current features increases the dimensionality and, therefore, the complexity of
the algorithms involved in the disag...
