For the last 10 years I have been paid for writing code which controls AC batteries (DC batteries plus inverter) or whole grids with fossil fuel, wind, PV, and batteries. I have seen small containers with a single 100kWh battery and 500MWh battery power plants. Some of them support tiny microgrids, like the (backup) power for a single hospital, others are cutting diesel consumption on certain islands down to 20%, and yet others provide primary control to Europe's biggest national power grids.

Addendum: I simplified things to the point where electrical engineers and battery chemists might feel physical pain. I have not talked about generator and battery chemistry inertia, active/reactive/apparent power, inverters being able to do both grid-forming or -following, genset synchronization, the dark art of black-starting grids, and lots of other stuff. I skipped this partly because I deemed it unnecessary to get the big picture, and partly because I know too little about it. I apologize.
