Distribution Test System for Nontechnical Loss Detection

The problem of nontechnical losses (NTL) detection using pattern recognition methods has been studied by many research groups. However, a comparison between the methods proposed by those authors is hardly ever possible because a database for comparison of NTL detection methods has not been made available to the research community. In this paper, we propose four variations of a database based on the IEEE 123 Bus-Test Feeder for testing NTL detection methods. The models and hypotheses used to synthesize the system are explained. An application of the Optimum-Path Forest classifier for NTL detection using the aforementioned database is also presented. The database is in Matlab platform and is available at http://www.power.ufl.edu.
