FAST-Enabled Controller-Parameter-Parameterized Immittance Transfer Function for Retuning Black-Boxed Inverter-Based Resources

Frequency-domain passivity analysis enables stability screening of black-boxed inverter-based resources (IBRs) directly from measured immittance; however, industrial retuning is often constrained by the lack of a direct mapping from stability-margin targets to controller settings.
