Smart Meter Advert.

Zoomup
On page 16 of The Times today an advert features that school girl eco-warrior whose name escapes me. The advert says I WANT TO HELP FIGHT CLIMATE CHANGE. I WANT A SMART METER. It says "Smart meters can't solve climate change on their own. But with the smarter, more efficient energy grid they help to create, they're a start". There is a circular logo which says "The campaign for a smarter Britain". I thought that I was reading Private Eye.

    perspicacious:

    I still think that the idea of having appliances with a built in frequency sensor that will switch off the non-essential appliance should the grid frequency fall to say 49.9 Hz is good. This flies against the historic practice of maintaining 50 Hz no matter how much spinning reserve this requires. I like the concept that the grid would be permitted to fall slightly to trigger load shedding by appliances or heaters whose non functioning for say 15 mins would not make any real difference to our lives and when the peak demand passes (as it always does) the frequency rises and the appliances return to normal. I suspect that instead of all being set at 49.9 Hz there would be a small range to avoid a surge though! I've put 49.9 Hz simply as a number to illustrate, but suspect those with more knowledge will give a better example.

    Maybe, if grid stability can be maintained. If enough stuff switches off at one frequency and back on at another, it may well lead to frequency instability due to generation ramping fighting load variation. There would need to sufficient damping in the system for that not to happen.
