Grid-Connected Converter With Grid-Forming and Grid-Following Modes Presenting Symmetrical and Asymmetrical Fault Ride-Through Capability

IEEE Journal of Emerging and Selected Topics in Power Electronics
Grid-connected converters must remain coupled to the grid during a fault. They have to control the reactive currents injected to the grid because of its limited overload capacity. In particular, grid-forming (GFM) converters ride through the fault either
