I personally don't know, I could probably work it out for the West coast, as that's where I live and worked.If the East Coast went down totally, how would we restart and how long is it likely to take before it would be back working correctly.......................
The french spanish border follows the Pyrenees range summits, few crossings, 2000+m asl except on both seasides, and moreover very low population density but for coastal areasFirstly a transmission map for that part of the world showing the big picture that it's highly interconnected, far more so than Australia or for that matter the US.
Colour code as follows:
Green = 220kV
Orange = 330kV
Red = 400kV
Dark red = 500kV
Blue = 750kV
Pink = DC transmission

Now looking closely at the border between France and Spain, I note that multiple lines on both sides are not shown as crossing the border. Whether that's due to topography, geology, historic political factors or a conscious engineering decision I'm unaware of, but bottom line is they do not connect. .
That being so, the actual connection between the two countries, and thus between Spain, Portgual and the rest of Europe, is quite limited.
I also draw attention to two DC links shown to form part of Spain - France transmission. Their existence isn't necessarily a problem, but it does raise a flag:

Sounds like a pretty good reason.The french spanish border follows the Pyrenees range summits, few crossings, 2000+m asl except on both seasides, and moreover very low population density but for coastal areas
I believe this explains the network
The other half is an avid cycle nut, so when we went to France and rented a car.Sounds like a pretty good reason.
I've been to France but never that far south so haven't seen the area. But if it's mountains etc then that explains why they didn't put too many lines through.
From the snippets, it sounds like Portugual's grid load is similar to W.A and Spain is similar to the East Coast of Australia.Impressive the amount of 500 kV line must have the load to use it?
The bright red throughout western Europe is 400kV, the 500kV being the dark red in Russia.Impressive the amount of 500 kV line must have the load to use it?
The biggest red flag I'm seeing here isn't that they've had a cascade system collapse, that bit is clearly what's happened, but there's either genuine confusion or an intentional cover up surrounding it.
If it helps, a Southern France nuclear plant has been stopped and is now being under full check for damage as a direct result of the spanish blackout.The biggest red flag I'm seeing here isn't that they've had a cascade system collapse, that bit is clearly what's happened, but there's either genuine confusion or an intentional cover up surrounding it.
It's one thing to have the system collapse and to not understand what caused it. It's quite something else to be producing data showing generation running and load being supplied then to say oh no that wasn't real.
That lack of accurate data makes any analysis highly problematic beyond the observation that there's clearly been a cascade system collapse which in layman's terms is the second worst case scenario. The worst being physical destruction of equipment.
In terms of system operation since restoration, assuming the data is correct, the most notable change is very much lower solar PV generation. Very roughly it's been cut 40% or so. Maybe that's due to weather but it does stand out as a change.
The other notable change is lower nuclear generation and and extended period before a restart commenced. The incident occurred on 28 April, first nuclear output on 2 May so 4 days later and still nowhere near fully restored. The reasons for that I'm unware of, but it does stand out.
For the rest, gas and hydro did the heavy lifting in terms of initial supply restoration along with a contribution from wind, solar, biomass, diesel and of course supply from France and Morocco. But hydro and gas were the big ones. Coal, a minor electricity source in Spain, was back up and running early on the 29th.
That's all assuming data is correct.....
I find it weird the author is at a loss about why solar disconnected...i bet it is rooftop solar whose millions of inverters will disconnect automatically if they can not sync on a clean 50 htz wave.Spain-Portugal blackouts: what actually happened, and what can Iberia and Europe learn from it?
By analysing minute-by minute data, we can pinpoint the moment where it all went wrong for Spain’s power grid.theconversation.com
In the Melbourne CBD and surrounds, particularly Port Melbourne where there is lots of warehouse and factory roof mounted solar power, CitiPower has the ability to switch off this power.I find it weird the author is at a loss about why solar disconnected...i bet it is rooftop solar whose millions of inverters will disconnect automatically if they can not sync on a clean 50 htz wave.
That very functionality is used for safety..switching on blackout but also to remotely disconnect solar by throwing a different frequency
Clear as spring water
I lost money on the asx with a Perth based from memory attempt, great to power beacon etc, otherwise a waste of effortAre we missing a trick with wave power?
Six years ago, the West Australian Govt cancelled a deal for the company to build a wave farm in the Great Southern region near Albany.16 Apr 2019.Are we missing a trick with wave power?
