Abstract: In the emerging power systems Distributed Generators (DGs) are expected to play a vital role as it has a great impact on the operation and planning of distribution network. Installing the DG at optimum location enhances the system performance and improves the reliability. In this paper a method is proposed for finding the optimal location of DGs with their optimum numbers and a goal to maximize reliability of system, reduce the total power loss while improving the voltage profile of the system for different load conditions using Particle Swarm Optimization (PSO) and Neural Network (NN) to fix DGs and evaluate the amount of power to be generated.

Keywords: Optimal Location, Power Loss, DG, PSO, Optimal Size, Neural Network.
