Abstract: The availability of an adequate amount of electricity and its utilization is essential for the growth and development of the country. Development of distribution systems result in higher system losses and poor voltage regulation. Consequently, an efficient and effective distribution system has become more urgent and important. Hence proper selection of conductors in the distribution system is important as it determines the current density and the resistance of the line. This paper presents optimal branch conductor selection of radial distribution systems using intelligent method of Genetic Algorithm (GA) with the objective to minimize the overall cost of annual energy losses and depreciation on the cost of conductors in order to improve productivity. The back/forward sweep method is applied for load flow solution of proposed radial distribution system. Simulations are carried out on 69-bus radial distribution networks based on GA optimization method. Results obtained with the proposed approaches are compared. The power loss reduction and voltage profile improvement has been successfully achieved which demonstrate the effectiveness of the proposed methods.
