Dual-Port Grid-Forming Control of MMCs and Its Applications to Grids of Grids

This work focuses on grid-forming (GFM) control of Interconnecting Power Converters (IPCs) that are used to interconnect multiple HVAC and HVDC subgrids form a grid grids. We introduce the concept dual-port GFM leverages ability Modular Multilevel (MMCs) simultaneously its AC DC terminal voltage present two MMC controls. provide analytical results high-fidelity simulations demonstrate (i) is more resilient contingencies (i.e., line generator outages) than state-of-the-art single-port control, (ii) unlike does not require assigning grid-following (GFL) roles IPC terminals in grids Finally, we an in-depth discussion comparison proposed
