This research aims to enhance control strategies for offshore wind power HVDC transmission systems using DRU-MMC topology.
Proposed a reduced-voltage startup strategy for coordinated onshore-offshore systems.
Developed and validated an enhanced DC voltage control strategy under varying wind power conditions.
Conducted comparative analysis among three grid-forming control methods through simulations.
Fixed AC voltage control resulted in DC voltage ripples of 14.4%, indicating poor regulation.
The proposed DC voltage control strategy limited DC voltage ripple to 2.9% and bus voltage fluctuations to 1.3%.
DC voltage control was identified as the most robust grid-forming strategy for DRU-MMC systems.
