MISSION Project: Design of MV/LV hybrid AC/DC smart-energy grid

In the frame of the Italian Integrated National Energy and Climate Plan, the European green deal and the Fit for 55 package, the three-year national research project MISSION (Multivector Integrated Smart Systems and Intelligent microgrids for accelerating the energy transitiON) was recently funded by the Italian Ministry of Ecological Transition (MiTE). One of the project’s aims is to develop a demonstrator inside the Distributed Energy Resource Test Facility (DER-TF) of RSE to validate a MV/LV hybrid AC/DC smart-energy grid. This research infrastructure will improve the DER-TF capability for the experimentation of: i) innovative logic for the recognition, identification and counterfeeding of the MV distribution networks faulty feeder; ii) hybrid AC/DC distribution networks with three front-end-converter and a bipolar DC microgrid; iii) advanced measurement infrastructures of network quantities and cable joints diagnostic; iv) smart-energy systems with electricity, heat and gas production, consumption and storage. The paper shows the preliminary design assumptions and the first simulation results.
