Thanks for the reply. I'll have to test out the larger models (mainly for curiosity).

Agree that it could be of use for lecturers as most students don't need the full power of PSSE or PowerWorld for the stuff you do in introductory textbooks.

Best of luck in this. I recall during the last FERC Conference on Software that there was at least one academic presentation where they talked about trying to find a good way to visualize these things with a web browser. I can't remember what the specific challenges were though.
