"The example they gave during the presentation was the commercial break of Eastenders I think" I doubt that. Whatever sins EastEnders may have committed, a commercial break isn't one of them. It's on the beeb.

The question would be, will all the 'meters' like this swing the same way across the grid? The way power is dispatched, is by increasing the voltage at the sending end of a line that is connected to a point in the grid that is a lower voltage.
It is done by advancing the phase at the generator by applying more torque to the shaft.
If you want to predict how stable your part of the grid is, measure the voltage.
I once worked at a place with several steam turbine and two hydro dams all linked to the incoming grid for a total of about 300 megawatts.
If we watched the lightbulbs carefully, we knew when something blew or someone messed up, and there would be a rich pay packet sweeping up the debris and putting something back together.

Yes. I was. But the spike at the end of the match / the shoot out wasn't as pronounced as the one at half time. If I can remember how to post an image I will put the graph here. (And yes, I do think that watching the mains frequency is more interesting than seeing who is better at kicking a ball round a field.)
