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 ...

Multichoice Control Strategy for VSC-HVdc
2007 iREP Symposium - Bulk Power System Dynamics and Control - VII. Revitalizing Operational Reliability, 2007 Multichoice control strategy -MCS-consists in the selection of the correct input signals that will allow the VSC-HVDC to enhance the transient stability of the system, increase the level of damping, provide voltage support at specific nodes or change the power flow in the system, as it is required by the system when disturbances occur or ordered by the
