All of that matters, but I think the parent post was only calling out the hospital equipment as a bad example. Like how your keyboard and your SSD don’t care what the grid is doing as long as the PSU can handle it.
But back to maintaining the frequency on the grid, along with keeping it within tolerance don’t they also have to make sure that the average frequency over time is VERY close to the target? I believe there are devices that use the frequency for timekeeping as well, like some old plug-in alarm clocks.
Fair enough. I was getting frustrated because I was trying to make a larger point about the fact that the grid can’t endlessly handle production. At some point the grid has to say “it will cost you to dump this onto the grid”. And suddenly I found myself discussing PSUs. I mean, yes, I’m aware there’s equipment on the grid that can handle different frequencies better than others but I felt we were discussing the bark of a single tree when I was trying to talk about the forest.
It really is a good point you make though. There’s a large balancing act to produce the right amount of power at exactly the time it’s needed. I think in our daily lives, and especially for non-tech/STEM folks, electricity is just taken for granted as always available and unlimited on an individual scale. I think people don’t envision giant spinning turbines when they plug something in, just like they don’t think of racks of computers in a data center when they open Amazon or Facebook.
Maybe it will be less like that in a couple decades when there is distributed energy storage all over the grid, including individual homes & vehicles.

Also fair enough!

I mean I envision the data centers. I also envision the turbines. Am I doing it right?
