The supplementary damping controller (SDC) in the doubly fed induction generator (DFIG) is to suppress the angular oscillations among synchronous generators (SGs). Due to the phase-locking error, the coupling between the SDC and the phase-locked loop

This paper analyzes the factors affecting the stability of phase-locked loops (PLLs) in weak power grids. By establishing a PLL model in weak power grids, it is found that line impedance, grid frequency disturbances, and output power all have an impa
