They don't need that kind of control, as evidenced by the fact that this kind of control is largely absent today for residential-scale grid-tied solar installations.

The way it works today for common residential grid-ties is this:

1. Is grid up? Y/N

2. If Y, then supply excess locally-generated power to grid. (Someone will implicitly use it.)

3. If N, then turn off connection to grid. (Nobody's home and we don't want to hurt anybody.)

It’s a bit more sophisticated than that. On a mild sunny day your local network will be saturated with PV power and the supply voltage will creep up. It’s an enforced regulation here (Aus) that the inverters will curtail/shut down based on grid over voltage. No networking required.

I think we're describing aspects of the same thing.
