Grid-forming control is central to the renewable energy transition, with Virtual Synchronous Machine (VSM) control emerging as a leading approach. By emulating synchronous generator inertia and damping, VSM enables converter-based sources like wind turbines to support grid frequency. However, increased power extraction during disturbances causes rotor deceleration and higher currents, risking aerodynamic stall or current limit breaches. This work explores optimal turbine tuning/operation to maximise inertial support over the full operating range while accounting for these stricter limits compared to conventional machines.
