If you ever wondered how the power grid works with all of its oscillations and attempts to synchronize power generation and power demand over such a wide area, consider this:
32 Metronomes synchronize together on their own over the span of 5 minutes. Truly remarkable.
In much the same way, synchronous generators and motors all over the power grid can eventually find synchronicity — that is if you wait long enough without disturbing them. But then if you can’t wait that long then…well…smart grid of course.
