This paper deals with the interconnection between the microgrid and main network. The Dynamic Voltage Restorer (DVR) is interfaced between the main network and microgrid in order to improve reliability and limit fault currents. The performance of DVR is demonstrated during fault conditions in two different locations, firstly in the main grid and then within the microgrid. The DVR injected a voltage during a fault in the main grid isolating the microgrid from the fault and performs normal operation. Secondly, a novel technique is proposed, magnetizing inductance of the DVR series transformer in order to reduce the contribution of the grid currents during a fault within the microgrid. The proposed technique is evaluated using MATLAB/SIMULINK.
