Abstract :

This paper optimally sizes and places DGs appropriately based on voltage stability indicators as well as power loss reduction indicator. The DG operating modes were also considered for power quality improvement. Since the problem involves optimization of these indicators, a new hybrid optimization method that integrates two well established techniques is proposed. The proposed technique modifies conventional PSO using Evolutionary Programming concept to improve the search process for better optimization results. The Modified PSO algorithm achieves better results when tested on IEEE 33- bus distribution systems. The results obtained shows that as load increases, the voltage stability indicator gives the best optimal DG size and minimum power losses for all the DG operating modes.
