A Novel Dynamic Voltage Restorer

In this paper author has tried to present a new approach for integrating grid connected photovoltaic (PV) system together with a self supported dynamic voltage restorer (DVR). In this paper author has also tried to present different three topologies of DVR, the suggested three topologies are filtering schemes, dc-link capacitor and three phase four wire ofa three phase transformer connection. The DVR has becomepopular as a cost effective solution for protection of important or sensitive loads from voltage dips and sags. The new methodology direct Quadraturebased DVR technique is presented. While implementing this technique MATLAB power Simulinkis used
