Optimal distributed generation placement to reduce power loss using Particle Swarm Optimization method

Abstract

In electrical power systems, distribution networks have considerable power losses compared with the other parts of electrical power systems. This caused by the distance of power plant to the load center. The high value of power losses causing disadvantage for the electricity provider company. This study aims to reduce power losses in the MLBC feeder distribution network by erecting the distributed generation. The optimal location for erecting distributed generation sought by using the Particle Swarm Optimization (PSO) method. Before distributed generation erected in MLBC feeder distribution network, the power losses' value is 128.1 kW. Locating the most optimum location for erecting the distributed generation is using the particle swarm optimization method, bus 13 on the MLBC feeder distribution network was the optimum location for distributed generation erection. Hence, the loss value from load flow simulation is 67.5 kW or 60.6 kW for power loss reduction after distributed generation installed on bus 13.
