Optimal Reconfiguration of Radial Distribution System Having Photovoltaic Distributed Generation with Controlled Voltage

Network reconfiguration is the process of changing the status ofsectionalizing switches and tie switches present in the network. In this paperoptimal reconfiguration has been done for the radial distribution system having photovoltaic distributed generation with controlled voltage, by using minimum voltage difference based reduction, which is a load flow based reduction technique and the penetration of these photovoltaicdistributed generations into the distribution system necessitates an appropriate load flow technique to analyze thedistribution system voltage profile and power losses. So to perform optimal reconfiguration for the radial distribution system having photovoltaic distributed generation with controlled voltage, improved backward forward sweep method, considering line flows and quadratic equation based solution is employed in this paper and these photovoltaic distributed generations are modeled as PV nodes. This method is tested on a 33 bus radial system and results have been presented.
