I have talked about this before on the forum and elsewhere. If one looks at the grid status at the moment it is about 27% wind and 24% gas turbines. The wind is gusty and so the peak capacity from it may be 50%, as there is no particular mechanism to control the output from a synchronous wind turbine.  This puts a huge problem on the grid and stability is simply not possible, leading to automatic shutdowns. I have a suggestion that the gas unit may have become unable to follow the rapid frequency changes, leading to massive reactive power surges and so shut down, and then the lack of availability and low frequency led to the power shedding and wind shutdown. We shall see what is said but blaming National Grid is certainly not the answer, I'm sure they do not want out of control wind sources connected at all. The lesson may well be that wind sources are too unstable to be directly connected to the grid.
