A meshed HVDC power transmission network comprises at least three HVDC converter stations interconnected in a first closed path by at least three transmission lines. A first DC power flow control device is series connected to a first of the at least three transmission lines. That first DC power flow control device takes its power from the first transmission line and balances the DC current distribution in the first closed path.
