Abstract

Non-technical losses or commercial losses cause financial losses to power utilities and weaknesses in the distribution power grids with damage to power quality (with an increase in blackouts) and the power grid reliability due to undue changes in the grid topology. These losses are commonly caused by theft (clandestine connections) and energy meter fraud. There are significant technological advances with the advent of smart grids and phasor measurement units (PMUs) at strategic points of distribution power grids. However, these advances are not available on a large scale in developing countries, particularly those with the most significant losses. Therefore, it is necessary to study methodologies for preventing and combating non-technical losses in conventional distribution power grids. In this sense, this project aims to implement a comparative analysis among soft computing techniques to identify irregular consumer units such as ARTMAP Fuzzy neural network and support vector machines (SVMs). Field inspections are time-consuming and have a high person-hour cost. In this way, identifying the most appropriate technique for detecting irregular consumer units minimizes false positives - unnecessary inspections in regular consumers.
