Freeze the nine-bus case, load set, and operating limits

Freeze the nine-bus case, load set, and operating limits

Record the IEEE nine-bus network data, the load scenarios to be tested, the voltage bounds, the thermal ratings, and the power flow formulation. List every single-line outage in scope. Deliverable: A case file with a checksum, a scenario list, and a limit table with bus, quantity, lower_bound, and upper_bound.
