'No big deal" Just an atmospheric phenomenon' some outages green energy absolved

What is your point? 70 hours is nothing.

My point is that some people point the fact that Spain achieved 100% renewable energy supply for one day, as if that in itself was a source of problems.

It isn't.

I'm reminded of a Looney Tunes cartoon where Yosemite Sam decides to go all solar power for his house. Then a series of storms comes, the sun hides behind thick clouds and he loses power so he has to go stay with Bugs and Daffy at their house and hilarity ensues.....

I know next to nothing about wind, solar or other forms of renewable energy, and am learning along the way. I have my own thoughts and biases that I am trying to balance.

But there is no proof it isn't the problem. Until it is 100% for years non stop, it is still just an unproven technology experiment.

But it would be if the power drop was related to the source of the power.
The cascading caused the outage.

No, it would if the power drop could only happen with that source of power.

If I'm not mistaken, it was a drop of 15 GW at a time that represented almost 90% of all the solar (photovoltaic) production, so I doubt 90% of all solar panels or inverters in Spain somehow suddenly failed.

The cascading caused the outage.

Obviously.
If you are producing 100 GW for a demand of 100 GW and suddenly the production falls to 50 GW, the system is always going to shut down, otherwise it would turn into a giant version of connecting a 2 A charger to a laptop that demands 5 A.

Can extra radiation from solar winds and a magnetic field shift/weakening effect power inverters but not effect vehicle batteries and electronics and the like?

 The short answer is yes and it has. We are due for another Carrington event. I think they occur every one hundred and fifty years on average. Highly charged particles hit the earths magnetosphere and get deflected to Earth through the magnetic field lines. If the intensity is too great for the field lines to handle then they go to earth through the next best thing. Which at the moment are long distance transmission lines. In Carrington's times it was telegraph lines. The normal frequency of the transmission lines is upset and the energy will flash through the transformer depending on the amount of energy most likely will blow it apart. In the worst case scenario the transformers rectifying the high voltage lines down to the Houshold level will also blow.
  It will also blow the capacitors in small electrical appliances if the device has an earthed circuit .
  There have been many reports of lights in buildings going into a flashing mode and street lights of the LED nature changing from white to blue, probably due to blown capacitors. because the Earths magnetic field is weakening it could be a patchy sort of weakening where plasma can get through at these points and seek places where it can go to ground in good electrical conductors. The energy usually dissipates in the ionosphere with a stable strong magnetic field. 
  Many ancient structures show signs of stone being melted, as the plasma earths out on the next best thing, So the future might be fun as the earths field gets weaker, and the south Atlantic anomaly gets bugger, and the plasma balls go flashing around as the pretty auroras light up the sky. I would think Victorian technology as backup to be on the safe side.Sun dimming and 75 hours of supplies wont cut it.

While you got the rest right, the flashing and blue/purple streetlights are just cheaply made.

They make them as cheap as possible. That means no surge filters and the like. They just partly burn up when they blink. When they turn blue/purple, the glue fell apart. They were made with uv LEDs with phosphorus filters glued to them. The glue fails and part of the filters fall off revealing part of the uv light. Only one manufacturer has that problem and they are spending millions replacing them under warranty. I saw a YouTube video on that this week. The glue only lasts about 5 years.

Has anyone considered the wind just stopped blowing for an extended period of time unexpectedly? It fits the atmospheric anomaly. The loss of that sugnificant portion of generation capacity caused the rest to fail by overload.

Now they are too embarrassed to admit the cause is so simple. Bad planning in the whole system overall.

Government fall down, go boom. Government made or let the power companies do a bad engineering failure.

  Thanks for that bit of information.
