Abstract :

Micro grid plays an important role in power system. In recent years, renewable resources are becoming a most promising green energy sources all over the world for electricity production and for meeting out the today’s demands, hence micro-grids are becoming widespread. A micro grid is a local energy grid with control capability, which means it can detach from the traditional grid and operates autonomously. The integration of Micro grid to the utility or grid through power electronic converters has risen worried about the quality of supply voltage. In this proposed work, in order to compensate for voltage sag and swell in the Micro grid system Dynamic Voltage Restorer (DVR) is used to inject three phase voltage in series and it is in synchronism with the transmission line voltages. The main objective is to enhance the Power Quality by using Dynamic Voltage Restorer (DVR) in a Solar PV and Battery integrated Renewable Energy System (RES) and to compensate the voltage profile. The system is simulated using MATLAB Simulink.
