Abstract In this paper a new methodology is used to reconfigure the topology of distribution system and placement of Distributed generators (DG) optimally. This methodology is adopted from the three optimization techniques which are Genetic Algorithm (GA), Particle Swarm Optimization (PSO) and Blue Whale Optimization (BWO). The basic principles of the GA is used the optimal switching, the foundation for the swarm searching techniques, PSO is used to find the optimal placement and latest optimization technique, BWO is used to find the size of the type-III DG. The major objective of the paper is to minimize the losses through optimal reconfiguration and optimal placement of DG in balanced radial distribution system. Keywords BIBC Matrix .

Introduction The increase of the global warming, mandate the researchers to look for the other alternative for generating the electric power. But, the generation of electric power through renewable sources cannot meet the required demand of the power system. So generators are erected at the consumer side which are called distributed generators, designed using PV systems, wind turbines etc. Power system is the combination generation, transmission and distribution. Distribution system is the tail end which supplies the electrical power to the consumers. The demand of electricity is rising day-to-day. The increasing of electrical demand is due to rise of population and the people customizing their needs towards the luxuries. To meet with the increasing load with existing resources is more complicated issue. By the increasing usage of conventional sources like coal

and crude oil the pollution increasing day to day as well. The contribution of the losses from generation to transmission and transmission to distribution are also high. The vain of reducing the losses at the mentioned systems are also reduced the usage of conventional fuels. By optimal placing of compensating devices at the transmission and distribution system will meet the goal of reducing the losses to great extent. But the erection and maintenance cost of compensating devices are also so complex. Mew E. Baran and Felix F. Wu [1] introduced the concept of reconfiguration of distribution system at their paper on 1989. They introduced the terminology of tie switches to change the structure of the radial distribution system for maintaining the load balancing throughout the system. M. M. A. Salama, A. Y. Chikhani [2] proposed an approac
