. . . What I think all this shows is that it is impossible to test system stability and protection in a live situation. It can be mathematically modeled by clever people but probably not in sufficient detail to be sure of the way the system will react. All we can hope for is that lessons will be learned from this event which will improve the models.
System stability and protection are indeed both modelled. Protection can be tested by injection from suitable test kit, but the only way to test system stability is a full blackout, but no one wants that to happen. The data collected will be useful to partly validate the model. The best “practice run” the UK has had, was the storm.s of 1987, where the grid in the south-east was blacked out and rebuilt using the black start procedure. Of course in 1987 there was much more inertia on the grid.
