Ricerca sul Sistema Energetico - RSE SpA, is a joint stock company, whose unique shareholder is GSE SpA, which develops research in electro-energy, with particular focus to the strategic national projects of general public interest, financed by the Italian Electricity System Research Fund (Fondo per la Ricerca di Sistema) of the Italian Economic Development Ministry.
RSE carries-out research into the field of electrical energy with special focus on national strategic projects funded through the Fund for Research into Electrical Systems. The activity covers the entire supply system with an application-oriented, experimental and system-based approach. RSE’s R&D activity is embedded in national, EU and industry co-operations focusing on sustainable innovation of the electrical system in the new liberalized scenario, exploitation of renewable energy and the application of DG concepts, as well as the study, testing and experimentation of new important technologies as information and communication, power electronics, DC distribution, energy storage and superconductivity. RSE has been carrying-on for more than ten years a research activity aimed at the design, development, testing and in-field experimentation of Superconducting Fault Current Limiters (SFCL) for MV grids. This activity led to the installation of the first Italian SFCL 9kV/3.4MVA in the MV grid of Milano, that successfully underwent a more than two years long live-grid activity, showing its limitation capability during a real and severe three-phase short-circuit. In past years RSE was also involved in the design, development, manufacture and test of different innovative components, such as 1MVA/1MJ SMES prototype. For the forthcoming years, it is foreseen to continue the SFCL activity by means of the design and testing of a new upgraded SFCL device (9kV/15.6MVA); at the same time, different applications have been already considered and their study already launched, such as a preliminary study about simulation methodologies for Superconducting Wind Turbines and a modeling activity concerned with thermo-fluid dynamic of cryogenic coolant flowing in forced convection regime inside HTS cables cryostats.
