Abstract:

Nowadays reduction of distribution system losses is the most important priority in design and operation of electrical networks. In an electrical network a significant percentage of power and energy produced in power plants is wasted in the path of generation to distribution system. Losses may appear in all levels of power system, i.e. generation, transmission, and distribution system. High current levels, low voltage levels, and radial structure of distribution system lead to a high percentage of losses. For instance, in 2010, approximately 75% of losses occurred in distribution systems in IRAN. Several methods have been proposed to reduce losses, such as capacitor placement in medium and low voltage levels, reconfiguration in networks, increasing cross section in conductors, etc. In recent years, the approach of decreasing or eliminating low voltage distribution networks has been proposed. In this study, at first, the origins of losses in distribution system are reviewed and then strategies for loss reduction are investigated. Then, by decreasing of length of low voltage distribution system in a sample feeder in Mazandaran province power Distribution Company, losses and voltage drop is calculated. Finally, the economic justification of the proposed solution is presented.
