How to model multiple infinite buses?

edit

I decided to post in here because my question is relevant: "How do I model an infinite bus?" To be more exact, I need to model many infinite buses so "How do I model a number of infinite buses in a case?" I am asking in both load flow network data and dynamic model terms.

1. What bus type do they need to be? Generator buses or Swing buses?
2. Voltage schedules need to be set to 1, right?
3. H (inertia) and D (damping) in Dynamic Data have to be 0, both of them ?
4. No controls, no governors, no nothing?
5. Generator model is GENCLS, right?
