Yes, in essence voltage and frequency are all that must to be monitored. I
think the unfortunate thing is to date most co-generation has been designed

Exactly.  As I said:

If you have lots of *tiny*, independent cogeneration facilities (e.g.,
rooftop solar), all the moreso as each of them can act without
involving others.

Cogen means extracting power (like otherwise waste heat) from some
process.

Rooftop solar is not often cogen.

What if my system is TAKEN off-line (because I'm having the roof repaired)?
That (those!) abrupt removal of capacity has to be anticipated instead
of some MW plant whose absence can be planned.  Likewise for new capacity
brought on-line haphazardly (yet another rooftop system connected, today!)

One rooftop solar array is parts-per-million of a national power
system. One more or less is unlikely to crash the system... although
it could.

One anchor dragged across the underwater feed from an offshore wind
farm could be interesting.
