Optimal Location of DG Units using Sensitivity Analysis

Abstract: Now a days the usage of electrical power is increasing enormously and it is also becoming highly impossible in the future world without the electricity. One of the techniques for maintaining the continuous supply i.e., by generating the electrical power in the distribution is presented . Distributed generation (DG) play an important role in distribution networks. Among many of their merits, loss reduction, THD reduction and voltage profile improvement can be the salient merits of DG. If the placement of the DG is done in non-optimal locations with non-optimal sizes of DG units may lead to increased losses, poor voltage profile and injection of harmonics in large quantity which in turn implies in increased cost of the system. In this paper, Sensitivity Analysis is used to determine the location of DG and Particle Swarm Optimization (PSO) is used to determine the size of DG to minimize the power losses in the distribution networks.The proposed PSO based approach is tested on standard IEEE 33 bus test system. The results so obtained show the improvement in voltage profile, reduction of real power loss using MATLAB.
