Hum interesting but I think based on a false premise that the grid
has the *exactly* the same frequency *everywhere*. The frequency will
be close but not exact, the many sets that supply power to the grid
are not connected by a hard physical link but by a relatively elastic
one of the long reactive grid distribution lines.

All the generators that are connected together most certainly *have*
exactly the same frequency. All of them. Can you imagine the
destruction that would result if they didn't?
