Abstract – The Doubly Fed Induction Generator (DFIG) based Dynamic Voltage Regulator (DVR) is used for the consumer protection from the grid voltage fluctuation like long duration voltage variation and short duration voltage variation. This paper analyses the operational principle of DFIG base DVR. It is designed by PI control technique and the decision making switch is used to compensate long duration and short duration voltage variations. Super capacitor and fuel cell (hybrid system) is used to compensate the fault during short duration voltage variations. DFIG is used to compensate the long duration voltage variations. The DFIG based DVR is established using MATLAB/Simulink.
