Base Python code for a DC load flow interconnection prospecting study in PSS/e

edit

We have an interconnecting prospecting study and need to run:

1. A straight PSS/e DC Load Flow (locked transformer taps, no switched shunt capacitors)
2. Test for overload limit on a lumped aggregate modeled generator at a bus
3. Need to increment the load flow in steps of 5 or 10 MW to full Generating Unit Capacity

Does anyone have a python shell (or idev converted python shell) that incrementally tests limits to show thermal overloads ? Much thanks on all your help.
