Feasibility of HVDC Connection for Offshore Wind Farms in Italy

Offshore wind energy is crucial in the decarbonisation process and significant development is expected in the next decades in Italy, especially for the floating technology. A detailed techno-economic analysis was performed and, among the aspects considered, electrical export connection has been thoroughly investigated. The two technologies HVAC and HVDC have been considered based on their affordability: the results show an economic convenience in the use of HVDC cable over distances above 50 km from the coast, considering 1 GW offshore wind farm. Furthermore, a geographical analysis has been carried out to identify interesting areas for offshore wind deployment connected with HVDC technology in short-and medium-term period.
