The message seems to be that might makes right in a dog eat dog world.
The scientific evaluation would be that the first part is fascist and the second part incorrect: it's cooperation that builds lasting wealth and colonialism doesn't work anymore.

All the teachers I know agree. AI hampers learning for most children. Like mobile phones in the classroom they are counterproductive. I think long term a wise personal AI coach might be a wonderful thing but current AI is not that wise coach.

Onze holon studie is uit!
Holons (lokale semi-autonome energiesystemen) kunnen netcongestie oplossen en duurzame energie beter benutten.
Alleen al in Nederland meer dan 200 miljard euro waard!
De studie bewijst het maar oud denken zit ons in de weg.

And for those saying that grid forming inverters need some central signal to sync with the grid or to fall in line after keeping the lights on during a blackout. https://t.co/z0ycz9jPSY

For those saying: Spain has a lot of renewables and an outage so renewables cause outages.

@AukeHoekstra Bad voltage control after there was too much uncontrolled generation on the system caused by uncontrollable solar.

This tweet is getting a lot of traction but its an example of the expected misinformation. It's at odds with the official report and doesn't even understand the difference between controlling voltage and inertia. https://t.co/CTzqinPlLD

But even if you don't buy into that its pretty clear that the blame game is useless here and the solution is clear: allow the inverters of batteries and renewable energy to stabilise the voltage. Problem solved. End.

The future grid will be inherently stable bottom-up. It will consist of a society of nested micro-grids with the grid as backup. They will make energy cheaper, more resilient and more local.

And I predict it will go further: these battery systems with grid forming inverters with batteries attached will disconnect from the grid during a blackout and this effectively means they provide a firewall for everyone attached to them.

It foreshadows a future in which every battery system connected to the grid has a grid forming inverter. Every one of them becomes a source of frequency and voltage stabilisation.

The most obvious fix is to allow renewables to participate in voltage control. That was illegal in Spain at the time of the blackout. This alone would have prevented this incident. The grid code is updated now.

You have to understand that traditionally, grids were managed largely through frequency control. If the frequency went down that meant more demand than supply. So you quickly burned more fossil fuels. If the frequency went up you burned less. Simple.

But the frequency was fine and well managed. All that talk about inertia, FCR and FRR was beside the point.
The problem was voltage fluctuations.
Whole different ball game.
For example: voltage fluctuations are much more local.
And the fix for that is clear and easy.

The chair of the ENTSO-E (European grid operators) board Damián Cortinas stated at the press conference: "The problem is not renewable energy, but voltage control, regardless of the type of generation."

The final report on the Iberia Peninsula (Spain and Portugal) blackout is out.
A lot of people will be blaming renewables and talk about inertia. But the cause was bad voltage control and that's surprisingly easy to fix. Let me explain.

What I like best is that they are very very transparent. I always look at the annex with underlying assumptions and here I think it is well written, short but exhaustive and accurate. https://t.co/wxdjmwY0YG
