ABSTRACT
A multi-objective network reconfiguration based on Genetic Algorithm (GA) and Binary Particle Swarm Optimization (BPSO) approach is presented in this paper. The main objective of the network reconfiguration is to minimize the real power loss with limited deviation of the node voltages. The algorithm starts with categorization of the switching sequences for radial network configuration while observation of the Plosses and the profile of voltage were done. The final topology signified the minimized Plosses condition with all nodes receiving power with acceptable voltage profile. The result of simulations on IEEE 57 bus system is given and compared with the initial case which has all switches closed. This method proved that improvement of Plosses has been made by change of the switching topology. The simulation is done both with GA and BPSO technique in MATLAB environment. Comparison shows that BPSO gives a better optimized result in much less time than GA.
