• Abstract

  Currently, non-technical losses detection is an active and a very concerning problem, mainly in development countries such as Brazil, where the amount of illegal connections may reach worrying levels. Such connections can somehow compromise the lifespan of devices usually employed in the energy transmission and transformation, since they were firstly designed to work under a certain amoun…

  Probabilistic models for commercial losses detection, AP.R

• Abstract

  The identification of non-technical losses, also called commercial losses, has been of great importance in the last decade. By using datasets with hundreds of legal and illegal profiles, we can obtain a method to cluster data into subprofiles aiming to minimize the search for consumers that lead to a large amount of thefts, or even to classify all samples from such datasets in legal or il…

• Abstract

  The Energy Efficiency have been the main topic of several projects and its results bring benefits straight to the electrical power systems preventing them to work in the border of their physical limits. Others points currently very explored are the concepts of smart grids and their infrastructure, demand response and their impacts and also the smart meters as the main devices of the elect…
