PEMFC supported dynamic voltage restorer for power quality enhancement

The continuity of supply and quality of power supplied to the customers must be uninterrupted from the reliability point of view. The Dynamic Voltage Restorer (DVR) is a custom power device which has an advantage of fast dynamic response and can generate real or reactive power independently. This paper presents the improved topology for DVR by the integration of Proton Exchange Membrane Fuel Cell (PEMFC) with boost converter as a DC input to the DVR. Thus the proposed DVR ensures a constant DCvoltage across the DC link during the process of voltage compensation with active power injection to the grid. The performance of the proposed work is endorsed by comparing the results with conventional DVR and the simulation results are also validated to prove the effectiveness of the proposed work.
