ABSTRACT The problem of multiple distributed generator (DG units) placement for power loss reduction in distribution systems is investigated in this paper using Improved Analytical (IA) method and Particle Swarm Optimization (PSO) method. IA method is based on IA expressions to calculate the optimal size of four different DG types and a methodology to identify the best location for DG allocation. In PSO method, a two-stage methodology called Fuzzy and PSO algorithm is used for placement and sizing of DG units. In both IA and PSO methods a DG injecting only Real power (P) is considered in this paper and are tested on IEEE 15 bus and 69 test bus systems. Voltage profile graphs are also plotted for both methods. Results shows that PSO method is effective when compared to IA method.
