Title: Electrical Losses Studies in National Grid
Author: Mohammed, Mohammed Faiz Ibrahim
Abstract: The global problem of the lower power availability to consumers is a consequence of power loss and no matter how carefully the power system network is designed, losses are unavoidable. Moreover, the present situation of losses in the power sectors is worrisome. The overall value of losses is fairly known as well as their likely sources. However, how large the magnitude of these losses is and where they come from remain unknown. Energy losses occur in the process of supplying electricity to consumers due to technical and commercial losses. The technical losses are due to energy dissipated in the conductors and equipment used for transmission, transformation, sub- transmission and distribution of power. These technical losses are inherent in a system and can be reduced to an optimum level. The commercial losses are caused by pilferage, defective meters, and errors in meter reading and in estimating unmetered supply of energy. A case study for technical losses was applied on the IEEE 14-buses using (ETAP) software which used Newton-Raphson method to solve load flow equations. Also the mechanism that used to reduce the technical and non-technical losses was implemented and discussed briefly.
