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 long distances with reduced transmission losses, and for the creation of multi‐terminal super‐grids currently being promoted for transitional dc grids in Europe. The technical feasibility of the proposed systems is assessed using simulations on symmetrical and asymmetrical tri‐pole VSC‐HVDC links, including the case of permanent pole‐to‐ground dc faults.
