A DFIG impedance reshaping method based on dynamic compensation of rotor current to enhance the stability in the mid-frequency band

Abstract Although the research on doubly-fed induction generator (DFIG) has gained popularity, the phase-locked loop (PLL) used in the DFIG system leads to frequency coupling with negative resistive characteristics in the mid-frequency band, which reduces the stability of the grid-connected DFIG sys...
