Grid Performance Enhancement Study Under Restricted Placement and Sizing of PV Distributed Generation

Abstract Increasing power demand and encouragement of renewable energy generation appear the importance Distributed Generation (DG). The Photovoltaic (PV) is considered a resource distributed generation. integration PV-DG unit into grid has significant effect on reducing real losses, operating costs, enhancing voltage stability. Most current researches handle this issue from point optimizing size location to enhance performance. In fact due optimal design criteria, PV are selected, implemented, no luxury for change. research, specific selection sizing placement in radial distribution systems was previously determined installed. main goal research study performance enhancement under these conditions. IEEE 15 bus system been taken perform based MATLAB environment. idea analyze when connecting each across transmission line find optimally connected considering available transfer capacity existing network. For enhancement, results show that fragmentation small units be all buses best solution.
