The effect of the types of network topologies on non-technical losses in secondary electric distribution systems

Abstract

A portion of generated electrical power is lost in transmission and distribution systems while serviced to endusers. These losses are called technical and non-technical losses in electricity distributions systems. With privatization processes taken place over the world, huge debate arose regarding nontechnical losses. In this study, information about types of losses in distribution systems, privatization process in Turkish electricity distribution network and current loss percentages are given. Possible alterations in distribution network topology to decrease non-technical losses are examined using analytical methods. Best methodology against non-technical losses is determined for different network topologies and customer characteristics, using AHP method. Choosing a pilot network, in which losses are considerably high, a case study is conducted. Cost-benefit analysis is performed within the scope of case study. Results of the case study indicate substantial potential for reducing non-technical losses by just altering network topology, where 1.6% reduction in overall T&L rates is estimated.
