Improving the energy efficiency of a Power Distribution Network by Loss Reduction: A case study in rural 11 kV Feeder

Abstract

Inherent losses occur when electrical energy travels from power generation facilities to end-users. Several utility companies do not recognize the benefits of modernizing their distribution systems or conducting assessments like load flow analysis to identify technical losses and performance indicators like voltage levels at customer service points. Consequently, these companies persist in running their networks without conducting any technical evaluations regarding energy losses or the quality of supply. The research objective is to improve the energy efficiency of a Power Distribution Network by Loss Reduction in a rural 11 kV Feeder of Nepal. Various reinforcement techniques for efficiency improvement such as: Conductor upgradation, Capacitor placement, Integration with Solar PV are studied. Combined methods of Conductor upgradation with Capacitor placement and Solar PV with Capacitor placement are also considered. Finally, a financial analysis is done.
