Multi‐pole voltage source converter HVDC transmission systems [PDF]

open access: yesIET Generation, Transmission & Distribution, 2016
This study connects several modular multilevel converters to form multi‐pole voltage source converter high‐voltage dc (VSC‐HVDC) links which are suited for bulk power evacuation, with increased resiliency to ac and dc network faults. The proposed arrangements resemble symmetrical and asymmetrical HVDC links that can be used for bulk power transfer over
