Power systems for the DTT nuclear fusion experiment

The Divertor Tokamak Test (DTT) facility is a fundamental step of the European Roadmap for the exploitation of nuclear fusion as an environmentally responsible source of energy. The main scope of this facility consists in the investigation of alternative solutions that could be adopted in DEMO, the first power plant based on nuclear fusion that is expected to be connected to the European grid by 2050. The operations of both DTT and DEMO are characterized by unconventional loads and converters requiring high and discontinues powers up to 300 MVA. This paper presents the criteria and analyses for the design of the power systems of DTT, with a special focus on the electrical distribution grid.
