High voltage direct current (HVDC) transmission is discussed when it comes to transmitting bulk power over long distances, as it appears in scenarios where power is generated from renewable energy in remote and rural areas and transmitted to load and industrial centers. On the other hand, HVDC grids are limited to point-to-point and multi-terminal grids, with only a few terminals, and mainly static power flows today. Although many studies propose meshed HVDC grids with many terminals, such grids do not exist today and require new operation and control strategies for transmitting (volatile) power, compared to todays voltage margin and voltage droop control in use. In this paper, based on previous work, a meshed pan-European-North African HVDC grid and novel HVDC voltage control is introduced and applied to each other, and evaluated for a secure and reliable wide-area power transmission of volatile power in an interconnected system.
