Ask HN: Resources to better understand current energy production and grids

How can someone with a background in computer science learn enough about energy and electrical grids to make a relatively correct model/simulation of the energy production, distribution and consumption of say, a country?

I'm looking for resources you can use to learn on my own.

This might be an overly ambitious idea or a relatively simple one, I have no clue. Any insights to help me get started are very appreciated.
