Electric Distribution System Reconfiguration For Loss Reduction Using Genetic Algorith


This paper presents the solution approach for the optimal reconfiguration problem in distribution networks implementing genetic algorithm technique. Network reconfiguration in distribution system is changing the status of sectionalizing switches to reduce the power loss in the system. The main objective of network reconfiguration is to find the network topology which have the minimum losses during any conditions exists in the network. A network configuration is a valid solution to the problem if it satisfies reliability, security and other operation constraints.A genetic algorithm is adapted and used in this work. The primary case study system is a part of the Baghdad area distribution network. It consists of main feeder, 6 laterals feeders and 48 buses. The algorithm validity is verified first via application to standard systems. Results show that the genetic algorithm is suitable for off-line reconfiguration studies.
