Power Quality Improvement by using PEMFC-based Quasi Y-Source DVR

Power quality has an important role in modern grids. Voltage sag and swell are one the major issues for poor power quality in distribution side of power system. There are different custom power devices available for power quality improvement. DVR (Dynamic Voltage Restorer) is one of the best economic, fast and popular custom power device for mitigation of voltage sag and swell. In this paper, A DVR is modelled with PEMFC and Quasi Y-source inverter and Hybrid controller is proposed. Proton Exchange Membrane Fuel Cells (PEMFCs) as a promising clean energy source for DVRs. Present the Quasi Y-Source inverter as a suitable topology for DVR applications due to its buck-boost capability and single-stage power conversion.
