When disable_psse_generation_models_on_coupled_buses = true, and generation_model_level = transmission in simulation_settings.toml, the code goes down a path in snap.py that requires a parameter called transmission_ibrs. Because that parameter (and transmission_ibrs_std) are not defined in models.py , an AttributeError is raised.
This will cause problems when user defined transmission models are used instead of the ones already defined in PSSE, since this is when this combination of simulation settings would be used.
