Hmmm, I wonder how this would affect things in the future where this is widely used.
I.E. if you had both widespread solar usage and some kind of large blackout, would it be hard to get all your solar back online because it's all in the "waiting for the grid" state? And the grid can't come back at capacity because all the solar it's expecting is out?
I assume people smarter than me have this figured out, but just a random thought if anyone knows more.
Not just solar - most grid-scale generators have this problem. "Black start" is the search term you want to look for, and Practical Engineering has a good video on the subject.
Basically, only a relative few grid generators are actually capable of black starts. The rest need the grid to be already functioning before they can tie in and start producing.
Yes, starting up a downed grid is a difficult problem. Recovering from a large scale failure could take weeks. Longer, with blown transformers.
You turn on parts of the grid at a time.
