Linking Europe to Africa through long distance HVDC submarine interconnectors: methodology applied to the feasibility study and technical challenges to be overcome
HVDC  links  are  becoming  an  increasingly  popular  solution  to  interconnect  previously  isolated systems or to establish new corridors within highly meshed networks. As a matter of fact, HVDC links show outstanding advantages with respect to HVAC corridors such as full controllability of power flow avoiding the creation of parallel or, even, loop flows in meshed […]
