The frequency business is ********.

If the voltage falls locally future smart meters could "report back"
and turn a few local wind turbines/PV panels on. ;-)

Or maybe some of these as they become common.

(Co-generation)

Or maybe stored power in electric vehicle batteries.

This is what Smart Grid technology is about.
All these PV panels/small wind turbines will need controlling at some
point in the future. As they become more numerous, they can't be left
running uncontrolled as at the moment.

And they will also cut off non essential thing if needed.

Anybody who co-operates with all this will be rewarded. (As with PV/
other renewable power at the moment)

The important bit will be to monitor all this an there will be
financial inducements for people to do this. ie different prices for
importing/exporting power at different times.

We ain't seen nothing yet.

Sounds wonderful - you have charged your electric vehicle using solar
panels, along comes a grid issue, so your vehicle battery is discharged
into the grid - along with any electricity your solar panels are producing.

End result, flat battery. And goodness knows what else unable to run due
to being cut off.

At least with a traditional power cut you don't lose that which you had.
At least with petrol they don't empty your tank during power cuts. Mind,
if they autostarted your little backup generator, and fed that
electricity into the grid as well, they could then empty your
generator's fuel tank quite nicely.
