Grid-forming (GFM) inverters behave as voltage sources with an internal impedance. In the event of severe grid disturbances, this behaviour results in a high current response. Unless the inverter trips, this can lead to the destruction of the power semiconductors. Therefore, the implementation of a current-limiting method is essential to prevent tripping. One method is to use a virtual admittance to calculate virtual currents that can be limited an
