Abstract: The distribution generator (DG) may be defined as the small-scale power generation technology that provides electricity closer to customers. The positive impacts of DG are: voltage support, power loss reduction, support of ancillary services and improved reliability. The investigation is done to study the impact of multi-DGs on power losses using the line loss reduction index (LLRI). The study has been carried out on IEEE 14 bus system using Newton Raphson (NR) method for load flow analysis. The investigation is carried out with the insertion of DG at different locations and the minima point was found. The experiment was performed with different sizes of DGs in medium ranges. The analysis of the results show that simply by increasing the number of DGs in the system to reduce the losses is not beneficial all the time. Beside the optimal location and size of DG for the loss reduction in distribution system, number of DG is also a vital factor. In this work, it is concluded that the optimal number of DGs is very important parameter to reduce the losses. The study gives the optimal number of DGs that could be installed in the distribution system to have minimum line losses.
