Power Routing Strategy for an Offshore-Onshore Bipolar VSC-HVDC Interconnector

Marchand, J. (author), Perilla Guerra, A.D. (author), Garapati, M. (author), Gonzalez-Longatt, Francisco (author), Rueda, José L. (author)

Distantly-located offshore energy hubs need to be connected to the shore via High Voltage Direct Current (HVDC) links to allow for an efficient bulk power exchange. A bipolar configuration of the HVDC link is suitable for a point-to-point connection, as it provides redundancy, and, therefore, a larger reliability, e.g. half of the rated transfer...
