Özet

A portion of the generated electrical power is lost in transmission and distribution systems while serviced to end-users. These losses are called technical and nontechnical losses in electricity distributions systems. With privatization processes taking place over the world, huge debate arose regarding nontechnical losses. In this study, information about types of losses in distribution systems, privatization process in the Turkish electricity distribution network and current loss percentages are given. Possible alterations in distribution network topology to decrease nontechnical losses are examined using analytical methods. The best methodology against nontechnical losses is determined for different network topologies and customer characteristics using the Analytic Hierarchy Process 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 nontechnical losses by just altering network topology, where 1.6% reduction in overall theft and loss rates is estimated.
