I'm not an EPS expert, so I don't know the answer to your first question.
For your second question, I'm not sure what educational libraries consist of. Depending on what data you have, you can probably do signoff static rail analysis with port powergrid views. Depending on your application or goal, that may be good enough. Check the EPS User Guide for the chapter called Power-Grid Library Generation. If you have the data to generate the models, you can run the signoff static analysis.
