- In this paper an analytical approach is used for optimal size and location of SPV (solar photovoltaic) based MLDG (multiple location distributed generator) in primary distribution system. The main objective of this research includes power loss reduction and voltage profile improvement along with economic benefits. DGs (Distributed Generators) are placed at single location to improve the performance of the system with respect to the power loss reduction and voltage profile improvement. For further reduction of power loss and enhancement of voltage profile, the estimated optimal size of a DG at single location serve as a constraint in locating the SPV based MLDG in the primary distribution system. The proposed approach are tested exhaustively on an IEEE 33 and IEEE 69 bus systems and it is found that the power loss reduction and voltage profile improvement is 57% and 0.943908 to 0.977294 pu respectively for IEEE 33 bus system where as it is 29% and 0.94882 to 0.95727 for IEEE 69 bus system as compared to the single DG placement. Obtained results are compared with the base value and found better as compared to the other techniques. From this research, it is revealed that the placements of MLDG are more significant and economical as compared to single DG placement.
