The following is planned for MVDC distribution networks:

• the development of DC distribution grids at multiple voltage levels,
• the evaluation of the impact of inserting a Dual Active Bridge (DAB) converter into the grid to interface active MV and LV DC grids;
• the definition of criteria for connection of utilities in LVDC grids;
• the management of grounding and operation of multi-terminal MVDC grids under fault conditions; integration of MVDC connections into the MV distribution grid with a view to optimal power flow (OPF) assessments.

For LVDC grids, an experimental study is planned on the LVDC grid available at RSE in order to test the behavior of mixed AC and DC networks by meshing RSE’s Test Facility.

As for HVDC networks:

• multi-scale modeling methodologies are being developed to predict the acoustic field in order to assess the noise produced by the lines due to corona phenomena, especially in post-rain conditions with related experimental validation in the laboratory;
• VSC converter control strategies for increasing the virtual inertia of the system are being defined;
• The refurbishment of the SA.CO.I. with VSC technology to increase the connection capacity of renewable power is being assessed.
