A new methodology is developed for addressing the optimal DG placement problem (OPDG) in practical distribution system. The method takes all the possible load models and their combination. Using load clustering, load flow results are presented taking exponential models of each individual load model into account. This method closely resembles any practical distribution system and the analysis can be extended to real time case studies also. In this scenario, the optimal DG placement is considered by taking minimum voltage as a criteria for DG placement and sizing was determined by using PSO for total real power loss minimization. The proposed method was applied on standard IEEE 69 bus system and the results were demonstrated. The results demonstrate that besides the total real power loss minimization, incorporating DG also improved voltage profile and reduced reactive power loss also.
