None of this is possible with wind or solar generators and static inverters. They supply into grid whatever the wind or solar source can supply. There is no question of briefly supplying a bit more in response to a falling frequency.

It might be possible. Say an inverter, in normal circumstances, shoved only say 95% of the available power into the grid - sending the remainder into some local dump (resistive heater say). Then when a bit of extra power is required it could increase output (up to the amount normally dumped) pretty much instantly(*) - whether the need for more power is communicated by falling frequency or by some other method.   For wind, you probably don't even need to generate the extra electricity and dump it - but just tweak the angle of the blades slightly to catch a little less wind.


Certainly at the moment, where the primary aim is to produce as much as possible from renewables, we probably don't want to adopt such an approach - so keep using inverter designs that try to export every mW that can - but if we were in the situation where almost all our power was from renewables and so most of the time we had a bit of excess generating capacity lying around, it might be workable.


(*) - I can't claim the approach as a new invention - I've seems something along those lines in a old (probably 1920s) generator powered by a water wheel - with some very dodgy looking open frame resistances!
