Part of the dynamic simulation code is as follows. The initialization process for the dynamic simulation is skipped:

psspy.bsys(sid = 5, numbus=len(close_by_buses), buses = close_by_buses)
ierr = psspy.delete_all_plot_channels()
ierr = psspy.chsb(sid=5, all=0, status4=1, status5=1)
psspy.strt_2([0,1],str("fault_test_severe_local_bus_"+str(fault_bus)+"coal_retired.out"))
psspy.save("sim_start_severe_coal_retired.cnv")

It is a very bad practice to save the converted case (generators and loads) in a "converted saved case". In your example with suffix .cnv instead of .sav.

There is no real reason to do this. It is better to start every simulation from a normal saved case and a snapshot/dyre file. You can remove the save statement.

What does 'psspy.save("XX.cnv")' mean in a dynamic simulation? What is a .cnv file?
