Reliable distribution feeder reconfiguration containing distributed generation using Hybrid Evolutionary algorithm

One of very important method for saving electrical energy and loss reduction in distribution systems is distributed feeder reconfiguration (DFR). This process is carried out by changing distribution system topology by opening and/or closing of circuit breakers. Status of the circuit breakers is optimally determined to have an improved system operation and reduced power losses. This paper proposes a multi-objective hybrid evolutionary method for distribution feeder reconfiguration. The multiobjectivesoptimization minimizes power losses and improves reliability of the system. For this purpose a particle swarm optimization algorithm is used for solving the problem. Simulation results shows the efficiency of the proposed method for DFR.
