Stability and Synchronization of MMC‐HVDC Systems Using SRF and Inertia‐Based PLLs
IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.This study investigates the influence of synchronous reference frame PLL (SRF‐PLL) and the inertia PLL (IPLL) on the stability of grid‐connected modular multilevel converter high voltage direct current (MMC‐HVDC) systems. The findings highlight intrinsic stability limitations of PLL‐based systems, offering insights toward more stable, PLL‐less ...
