Coordinated Control of a Multi-Terminal HVDC Transmission System for Integrating Large Offshore Wind Farms
Voltage source converter based multi-terminal HVDC transmission system technology is proposed for integrating large offshore wind farms over long distance. Coordinated DC grid management using close-loop DC voltage control and DC droop characteristics are proposed, to ensure smooth system operation and proper power sharing among various DC converter stations. PSCAD/EMTDC simulations for a four-terminal DC system for connecting two offshore wind farms to two different onshore AC networks are presented to demonstrate the robust performance of the proposed DC management modes during wind speed and power variations, and large disturbances caused by the trip of one of the wind farms.
