True, but if you look at an entire country like Germany, only about 10% of the turbines will be in an area where the wind is too strong as the storm passes through, the others will still produce...

Some probably has to do as blades/axis could break due to stress, which there are videos of turbines with malfunctioning brakes spinning out of control and breaking. Mostly wind turbines have issues with frequency as you don't want to change/adjust frequency too much (adds to cost) to that of the main grid they only generate when within acceptable frequency ranges and internal equipment is able to compensate.

Modern wind turbines can angle their wings in a way that they can produce in conditions that would have required a shutdown 15 years ago. With this storm control the turbines lineally increase the resistance and are only shut down when the wind speed reaches more than 34 m/s as a 10 minute average. That's 122km/h. [0] The recent storm reached these levels at times, but didn't sustain them for longer periods over larger areas.

  Do you know a rough percentage for how many wind-turbines in use are modern turbines like these?

We don't really have to speculate, since energy production data is available [0]. There certainly was a lot of energy produced by wind turbines. About the same as last week (also quite windy). But the "entire countries are working at half capacity" doesn't seem to be valid, at last I don't see a dip in power consumption.

  Notably these graphs show that Germany was exporting quite a lot of power on the 10th, but was still burning gas, brown coal and hard coal in large quantities at the same time. Also nuclear, which I don't mind as much of the others, but still Germany has decided to phase it out so it seems Germany still needs more renewables.
