Electrical outages. cyber attacks ?

aligarjon
What's the chances of the power outages and airport problems being cyber attacks.     Is that possible.   I would think so  ?

    ...there are other strategies that could have worked, for example setting all running sets to maximum, requesting additional power from the European Interconnections, and even voltage reduction. 



    As I understand it, the 'reserves' the grid has (the 1GW figure being bandied around) is the additional power that is available by running all sets to maximum plus any additional power that can be drawn from the European Interconnections instantaneously. The whole point here is that these strategies were implemented and did not work. Reducing the voltage is a very tricky proposal and not one I would suggest. We have a defined supply voltage of 230V which I believe has a tolerance of +10%/-6% and additionally installations may have their own voltage drops from the supply to consumer of another 5%. If the voltage is dropped much below this -6% plus -5% we are getting dangerously close to the the level at which contactors may start to drop out, causing even more of an issue than a straightforward loss of supply.
