So even though your devices are not in themselves causing a frequency

His generation is on the distribution network. If the volts rise the taps
change at the bulk supply point although 2v at 230v is SFA in the grand scheme
of things as its buried in the noise of everything else.

Germany might be different because of the scale of deployment and location of
the generation but in the UK embedded solar generation is viewed simply as
reduced demand (an an irritation) As much as it pains me to say, a few
thousand roofs adorned with solar panels make bugger all difference to the
operation of the UK Grid, the only damage is the pocket of consumers who are
being forced to subsidise FIT parasites.
