Optimal Placement of Solar PV in Distribution System using Particle Swarm Optimization

Athira Jayavarma, Tibin Joseph

Solar PhotoVoltaics (SPV) are among the fastest growing energy resources in the world. Most of the SPV had been installed in the distribution systems as distributed generation. Now, a day’s Distributed generations (DGs) play an important role in distribution networks. Among many of their merits, loss reduction and voltage profile improvement can be the salient specifications of DG. Studies show that non-optimal locations of DG units may lead to losses increase, together with bad effect on voltage profile. So, this paper presents a new methodology using Particle Swarm Optimization(PSO) for the placement of Solar PV in the radial distribution systems. The proposed algorithm will identify the optimal location of Solar PV with minimum active power losses.. The developed algorithm has been tested on modified IEEE 14-bus test. The result shows a considerable reduction in the total power loss in the system and improved voltage profiles of the buses.
