The growing demand for using direct current (DC) in Low Voltage Direct Current (LVDC) applications has several motivations, including the use of LED devices, increased generation of electricity from sustainable and renewable sources, the widespread presence of electronic devices in everyday equipment, and the rise of electric mobility. These considerations formed the basis for RSE’s research activities. From 2015 to 2018, within the framework of the project “Transmission and Distribution Networks in Direct Current,” funded by System Research, the feasibility of reinforcing existing alternating current (AC) distribution networks by connecting multiple lines with DC connections (Medium Voltage Direct Current – MVDC) was studied, creating a mesh network and enhancing DC connections also in the transmission network (High Voltage Direct Current – HVDC). Additionally, a low voltage DC microgrid was developed and is available at RSE for conducting experimental validations of these activities. Alongside the technical activities, participation in national standards is active through the CEI 320 “Low Voltage DC Networks and LVDC” technical committee, for which RSE holds the secretariat.
