What Caused the European Power Outage? https://www.byteseu.com/984068/ #Energy #Europe #PowerGrid #RenewableEnergy #Science #SolarEnergy #Spain #WindPower
April's #BGStats #BoardGames 25 plays of 22 games. I finally got round to playing #PowerGrid - it was interesting, would certainly play again. The #Tablescope app for scoring #Cascadia quickly was probably my fave discovery of the month though!

Search for the causes of the #blackout in #Spain and #Portugal are ongoing, will likely take some time, and (I suspect) will result at least one PhD thesis. Because major disasters like this never have a _single_ cause - several things have to go wrong for them to happen.
The _easy_ answer which I know is already going to be shared by The Usual Suspects is:
" #RenewableEnergy is too intermittent and our power grids cannot cope with them! We need to switch off #PV and #WindPower and return to a centralized power supply!"
And as usual, the easy answer is at the very least misleading, if not outright wrong. It _is_ true that renewable energy is more intermittent. But power grids can be made more robust to cope with that intermittency.
I don't know how this is done in Portugal and Spain, but here in Germany the #Bundesnetzagentur (BNetzA, Federal Grid Agency) is in charge of regulating the German power grids. One of their recent efforts to make the German grid more stable is called "Redispatch 2.0".(*)
Under this scheme, the regional grid operators (Distribution System Operator, DSO) have to submit forecasts about their grids to the Transmission System Operators (TSO) - the companies that run the high- and ultra-high voltage power grids that connect different regions and countries with each other. These forecasts have to be submitted for 72 hours in advance, in 15 minute intervals, and be refreshed for every 15 minutes.
The TSOs can then aggregate all those forecasts and react in order to stabilize their grids. Options include:
If there is too much power generation, they can either reduce power generation or add some loads.
If there is too little power generation, they can either increase power generation or shut down some loads.
This should make it much more unlikely to trigger massive blackouts on that scale, or even smaller ones.
Another problem is that many PV installations, especially smaller ones, do not have the physical infrastructure to shut down if there is an excess of production - they just send their electricity into the grid, whether or not the grid can handle it. But this, too, is in the process of changing - it is now mandatory to install so-called Smart Meter Gateways with all such installations, and these gateways also have secure channels that can send control signals to the PV installation.
All this is still a work in process and not trivial by any means, but it _is_ possible to make power grids more resilient for renewable energy. And this is desperately needed for the #EuropeanUnion - we have little fossil fuels of their own, and most suppliers are increasingly authoritarian if not outright hostile to us. The sooner we get independent from outside energy sources, the better.

Power outage in Spain and Portugal still a mystery, but leaders vow to solve it and prevent a recurrence https://www.byteseu.com/967889/ #electricity #EuropeanUnion #Portugal #PowerGrid #PowerOutage #PowerOutages #Russia #Spain
'Induced atmospheric vibration'
The way to avoid such catastrophic risks is clear: we must embrace innovative solutions such as community #microgrids. These are decentralised, flexible and resilient energy networks that can operate independently when needed.
Just like #Fediverse.
Detailed article on the Spanish electrical grid failure and the "black start" procedure that they need to follow to bring the network back online.
Black start is essentially the opposite of a cascading power failure – a carefully planned and sequenced cascading reconnection of generators, circuits and loads.

#Spain #PowerGrid #BlackStart
Morning run views earlier. Power back in Spain. I have to say we were pretty fortunate for timing of the outage, given weather is lovely and people didn’t need heat or A/C, and there were many hours of daylight left so most people got power back on before dark or could get home before dark.

Why did the lights go out in Spain and Portugal?
And what does it mean for Europe, its power grids and its electricity?
Power is restored in Spain after a massive blackout leaves millions stranded.
Power returned to Spain early Tuesday after a major blackout disrupted flights, metros, and communications across Spain and Portugal.
Authorities said over 99% of energy demand was restored, but the cause of the outage remains unclear.

For a work thing, I recently read and wrote a whole lot about renewable energy and power grids, and power purchase agreements and renewable energy certificates and I had forgotten just how interesting I find this stuff. So I want to read more on this. Are there people on mastodon who geek out on this stuff on the regular who I could follow?
Cables.
Don't they say the power grid is a complex piece of infrastructure.
Kabel.
Man sagt ja, das Stromnetz sei eine komplexe Sache.
A solid review of Brandon Russell's sordid career, from Atomwaffen Division to prison to Terrorgram and back to prison, with a particular focus on his trial for plotting to destroy the power grid around Baltimore. He was found guilty on Feb. 3, and is looking at up to 20 years for that; sentencing is scheduled for June 17.
