Further comments

Major success. PowerWorld doesn't expose controls to lower the network solution below 1e-5 tolerance, so I think we are nearing the tightest validation error we can get with the PowerWorld reference.

Once this is merged, we should be able to remove the older cases from examples/PhasorDynamics/ so that the examples just consume the cases through *.solver.json

I'm debating whether to include this python code or not. At a minimum, we'd want some usage documentation and error handling for incorrect arguments.

Your call, I threw it in just so the style of the plots stays consistent. I don't have a preference
