Network Reconfiguration for Loss Reduction and Improved Voltage Profile in Distribution System with Distributed Generation Using Genetic Algorithm Abhijit

This paper presents a feeder reconfiguration problem to the distribution system with distributed generation. The main objective of this paper is to minimize the system power loss and improve bus voltage profile. The optimization problem is subjected to system constraints consisting of load-point voltage limits, radial configuration format. A method based on genetic algorithm to determine the minimum configuration is presented. A genetic algorithm is a search or optimization algorithm based on the mechanics of natural selection and natural genetics. The developed methodology is demonstrated by a 33 and 69 bus radial distribution system with distributed generation. The study results show that the optimal on/off patterns of the switches can be identified which give the minimum power loss while respecting all the constraints.
