High Voltage Direct Current (HVDC) cable systems have been singled out by the European Commission as a key enabler towards the green transition and a sustainable electrical energy market, since they are a well-suited tool for connecting massive and remote Renewable Energy Sources (e.g. Offshore Wind Farms) to the power grid. However, HVDC cable system components (cables, accessories, converter stations) have to face great challenges due to the harsh environment, the increasing voltage & power ratings, and the more dynamic duty service required by the electricity market. The seminar will treat all these aspects, focusing on the multi-year experience about HVDC cable links gained by Terna, the largest Transmission System Operator (TSO) in Europe and one of the major worldwide.    
Antonio Battaglia got the MD in Electrical Engineering at the University of Bologna, Italy, in 2013. Since then, he has worked with Terna, being deeply involved in the main issues relevant to HVDC cable systems and cooperating with the main players of the HVDC cable market worldwide, In particular, he is now part of the HVDC Technologies Research group of Terna, tackling the following main activities:
▪ Design of HVDC VSC and HVDC LCC systems (insulation coordination, current and voltage transformers, DC and AC equipment, LCC and VSC converters, cooling systems).
▪ Design of land and submarine HVDC cable systems (terminations, joints, electrical and mechanical calculations, magnetic fields, electromagnetic interferences, qualification and type tests, failure analysis).
▪ Design of land and submarine electrode cables, and electrode systems.
▪ Factory tests on converter station, HVAC and HVDC equipment, electrode cable systems and HVDC cable systems.
▪ Failure analysis on HVDC links
▪ Technological support for HVDC projects, drafting of technical specification for construction and testing of HVDC MIND and extruded cables, special test on cable system and LCC/VSC converter valves design.
▪ Evaluation and research about the life of HVDC cable system, under conditions of thermal and electrical transients induced by load variations.
