In this paper, the Particle Swarm Optimization (PSO) technique is used to determine the optimal coordination for Distributed Generator (DG). The DG output and location is determined simultaneously. Furthermore, this study covers both single and multiple DGs analyses. Five different Power Factor (PF) values are also assigned to the DG units, which are 0.8, 0.85, 0.9, 0.95 and 1.0. Thus, the impacts of DG power factor to the optimal placement and output are investigated. From the result, the optimal DG placement is similar, regardless of the PF condition. For the single DG unit, the optimal location is bus 6 and for three DGs analysis, the optimal locations are at buses 14, 24, 30. However, the PF significantly influences the optimal DG output, power loss reduction and voltage profile improvement. Three DGs with PF 0.8 is the best option to reduce the power loss in the distribution network to the lowest value.
