Adaptive active frequency support strategy for receiving-end MMC-HVDC stations based on rate of change of frequency

Frontiers in Electronics
As the proportion of HVDC infeed power increases in the eastern receiving-end power grid, inertia and frequency regulation capability decrease. Utilizing modular multilevel converter (MMC) stations at the receiving-end to provide active frequency support
