Optimal Sitting and Sizing of Multi-Distributed Generation Units Considering Load Pattern Using Particle Swarm Optimization to Reduce Losses

Using distributed generation (DG) units in distribution systems for loss reduction is a pervasive factor. But inattention to measuring and establishing place of DGs, not only don t help to loss reduction, but also may be caused to increase of losses in network. Many ways and algorithms have represented to find for proper place and capacity of distributed generation sources which constant load pattern in many of them was assumed, but when the system load is diverse with time, using constant loads analyses would be misleading. In this paper optimal location and sizing of DGs, using particle swarm optimization (PSO) algorithm with attention to diversities of load efficacious toward time in period of one year is discussed for loss reduction in distribution system. The results were tested on an actual radial distribution system
