Analysis of losses in power system and its economic consequences in power sector

چکیده
Power system losses can be divided into two categories: technical losses and non-technical losses. Technical losses are naturally occurring losses (caused by actions internal to the power system) and consist mainly of power dissipation in electrical system components such as transmission lines, power transformers, measurement systems, etc. Technical losses result from the impedance of the network components such as electric lines/ cables, transformers, metering and protecting equipment etc. Non-technical losses, on the other hand, are caused by theft, metering inaccuracies. The distribution system accounts for highest technical and non technical losses in the power system. The transmission and distribution losses in our country, which were around 15% up to 1968, increased gradually to 30% by 2012-13. Simply Electricity losses are defined as the difference between quantities of electricity delivered and quantities of electricity recorded as sold to customers. The purpose of this paper is to analyze Technical and Non Technical Losses and its economic consequences in power sector with the help of a case study and MATLAB Simulation in power systems.
