> TV pickup is a term used in the United Kingdom to refer to a phenomenon that affects electricity generation and transmission networks. It often occurs when a large number of people watch the same TV programmes while taking advantage of breaks in programming to use toilets and operate electrical appliances, thus causing large synchronised surges in national electricity consumption.
E.g. in football/"soccer" the half time break isn't at a predetermined point in time, as the start of the game can be delayed and the referee can and usually does give some extra time to make up for unplanned breaks due to fouls etc. Same after regular time in the second half. And if it's a knockout game, then you may even have real overtime and even a penalty shootout to find a winner. Then you have unplanned/semi-planned breaks like players getting a break to drink when it's hot, or... heavy rain or... the ref getting hit in the head with a bottle. And people will use these breaks to do their "business" and make tea/coffee/use the microwave oven. And after the game, players may stay on the field to celebrate or cry about the loss, which I would guess a computervision "AI" would have trouble distinguishing from the actual game.
Just having some people watch the game in the control room (which they probably would do or at least want to do anyway) is still easier and more reliable than trying to train an AI to detect all that, in my humble opinion :D
Of course, automation like automatically detecting and scaling the grid by looking at the grid itself would and does help a lot; but that's different from automating watching the telly.
I have to admit that I was asking that as a loaded question as my thinking was much like yours, but I didn't feel like typing it out. A human is probably the most reliable "AI" for the job :D.
The Intervision Song Contest (Интервидение), a second world alternative to Eurovision[1], ran the voting by telling people to turn off or on their lights, during specific time slots for each candidate. Supposedly they could tell by the electrical load on the grid who got the popular vote.
Good point. Nothing primary, and I only googled in english. Didn't try russian or yandex. It's plausible to me because Modi's Covid light stunt was distinctly visible on the indian grid, but it would be better if someone who actually watched Intervision (or at least knows how expensive long-distance calls were in the USSR?) could say something here.
(In a 1975 movie, Zhenya Lukashin offers to repay Nadya Shevelova for making a long distance call from her apartment, so I gather that, as in the west, non-local rates weren't trivial.)

Still no primary source, but if russian and US state owned media agree, and absent any personal recollections, I'm inclined to accept the story. (Unless our alien lizard overlords are behind the whole thing?)
Edit2: interesting, according to a documentary referred to in the google cache of http://www.alla-superstar.ru/component/alla/songs/song/91.ht... it took RUB 25 and a bottle of vodka to get Все Могут Короли past the censors in the mid-70s. (roughly between 1 and 2 benjamins in 2020 USD? From this point of view BTC makes a poor substitute currency, as one can't toast with it...)
A mid-80's western report on the "vodka economy" suggests that in this case the bottle itself was meant more as a traditional component of a bribe/tip, and probably didn't contribute much to the pecuniary value. (Indeed, one suggestion in the paper is that, just as the dollar lost its gold standard, during the seventies the ruble also lost its vodka standard of 3 RUB = 1 L.)

Yes, and Dinorwig is a special purpose 1.3GW pumped storage power station in North Wales that was built to help with the sudden demand from millions of kettles - it has the world's fastest response time! https://www.power-technology.com/features/featuredinorwig-a-...
Do the security services count disinformation as a threat to nation state security? And if they do, how can they detect it, prove it and stop it without becoming an arbiter of truth in democracies, where successful parties can profit from foreign-agent supplied disinformation? The article talks about practical concerns but the threat to state sovereignty seems as dangerous.
> Do the security services count disinformation as a threat to nation state security?
They probably do because they need to justify the huge, ever-increasing and uncontrollable budgets they're receiving. It also seems like "disinformation" and "fake news" have taken the place of the "terrorists" from the 2000s and early 2010s, I'm 100% sure I've seen many articles with titles similar to "Terrorists can bring down city's/country's power grid" back during those days.
Basically every large country is actively participating in it at this point against their rivals. (Yes that even includes you guys America - Operation Earnest Voice was just the beginning). You can't really call it out as bad when you are doing it yourself.
They realise it's a threat but also see it as an opportunity.
The US military were discussing meme warfare a decade ago. The Russian IRA basically pumps out this stuff wholesale.
Why label it disinformation? Even real information, presented in a "weaponized" way, can bring down power grids or entire governments. Limiting the discussion to just a certain kind of information, that we then prefix "dis", covers up the real problem. The real problem being that, while we very much value the open and free flow of information (free speech), that same freely flowing information can be weaponized and destructive. And SM has made it so much easier to weaponize information, both real and "dis".
I think you're describing misinformation. Disinformation makes people mistrust their news sources, so that any source of information might be as trustworthy as any other. That's why they would be susceptible to fake discount notifications like the ones described in the paper.
>Disinformation makes people mistrust their news sources
But the news sources themselves make you distrust them. I doubt that they are actively trying to make their readers mistrust them, but they seem to get that end result by simply engaging in politics.
> Disinformation makes people mistrust their news sources
I began distrusting the media in my country when the most reputable (publicly financed) news shows increasingly contradicted their own reporting. One day they reported "a", because they could spin it in favor of their SJW agenda, and the next day the reported the complete opposite about the same topic for the same reason. Sometimes it even happened within the same show.
So yes, you are correct, disinformation made me distrust my news sources. But it was the obvious disinformation spread by those very news sources.
This tactic of elevating your pet issue by linking it to a hypothetical catastrophe seems a bit unserious. A network model of how memes and beliefs spread is interesting, but they seem to adopt someone elses model in support of their idea. It's useful to apply extra skepticism to papers that link ideas to catastrophe, since it's likely using it as a vehicle.
However, an alternative interpretation from this is they may show it's possible to ascertain someone's political beliefs or alignment and select them for further investigation using their electricity consumption patterns, which if true, would be right out of the anti-smart-meter infrastructure conspiracies we encountered during SMI rollouts.

A very big outage in North America occurred from the cascading effects of a single breaker working as intended. The grid is a very complex system because it is dynamic and subject to states of vulnerability that may not be well understood.
> This tactic of elevating your pet issue by linking it to a hypothetical catastrophe seems a bit unserious.
I see it in the spirit of computer security research. "Here is a way evildoers could hack this system". Neither the form of attack nor the target need to be the most general to churn out such results.
My favorite power outage story is the 1998 San Francisco / Peninsula outage. Contractors were working on a substation so they disconnected the 115 kV line and strapped it to ground to protect against stray current. When they were done, they powered up the line. Unfortunately, they forgot to remove the ground straps.
It turns out that the power grid doesn't like it when you connect 115 kV directly to ground. By the time the ground straps vaporized, the fluctuations caused all the generators in San Francisco to go offline, cutting power to a million people.
Bringing the power grid back up took hours. Among other problems, they discovered that the SCADA modems in several substations ran off AC without backup, so they couldn't access the substations remotely when the power was down. Oops.
That's why the UK has a number of pumped storage schemes such as Dinorwig and Loch Awe. Typically this sort of facility can put 500MW into the grid from cold at about 1 minute's notice. With warning (so the turbines can be spun up to speed) the ramp up time is about 10s.
On the opposite side, I'd wish to make some large scale positive blips. Like facebook street cleaning challenges, or bike delivery day, or 1min cold shower week.

Funny things happen sometimes: french president Emmanuel Macron speech on TV on april 13th 2020 was followed by an estimated 36.7 millions people and led to 2.5 Gigawatt lower electricity consumption in France between 20:00 and 20:30 local time. Grid manager RTE lowered production by 1.9 GW for nuclear and 0.6 GW for hydro to match demand.
" L’allocution d’Emmanuel Macron, retransmise sur les principales chaînes d’information ce lundi 13 avril, a été suivie par 36,7 millions de téléspectateurs selon Médiamétrie.
Ce record d’audience se voit au travers de la consommation d’électricité des Français qui a chuté de 2 500 MW, entre 20h et 20h30, soit l’équivalence de la consommation d’électricité de Paris."
In certain places there are already systems that can handle when the system load is > available generation. When this occurs, the frequency of the grid drops and these automated systems begin dropping load. [0] has a report on such a system in New Zealand that triggered.
These systems need to drop load before the frequency gets so low that it causes damage to generating stations. In the 2003 blackout in the northeast US & Canada, load wasn't dropped fast enough and the protection equipment at generating plants tripped them off before damage could occur. For base generation like nuclear plants, you generally need to wait up to 72 hours to restart the plant [1]. One key reason for that long time period is the need to wait for Xenon 135 levels to stabilize. [2]
The paper actually considers these systems, but dismisses them because "Third, we disregard the possibility that power utilities react to the sudden increase in the demand either by increasing the available generation or through load shedding. As for the former reaction, it would be ineffective since the primary cause of the blackout in our simulation is the violation of the line capacity limits rather than a generation deficit. The latter reaction may also be ineffective in protecting the residential loads considered in our study since power utilities typically prioritize commercial, industrial and critical loads during such contingencies."
So in other words, end consumers would lose power, but the grid would continue to function as designed for critical loads. Hardly seems like the sky is falling.

All the nation's toilets also flush repeatedly at much the same time, which was a central plot point in the film "Flushed Away".
It's an interesting phenomenon, though I'd never considered that dealing with it could prepare us for a malicious attack some day.

I know it does (did?) on Twitch, last time I looked.

Social media information warfare is happening and is novel. Institutions don’t have a good process do deal with it.
