I think a real world solution to grid stability would require greater use of sensory devices (and a some sensory-feedback devices). I really don't know for sure, but my assumption is that electrical grid management has relied mostly on the electrical reactions of the grid itself, and here you are saying that is just not good enough for critical fluctuations in 2010. So while software is also necessary of course, the first change in how grid management should be done is through greater reliance on off-the-grid (or at minimal backup on-grid) sensory devices. I am quite confident, without knowing anything about the subject, that that is what needs to be done because I understand a little about how different groups of people work and I have seen how sensory devices like gps and lidar have fundamentally changed AI projects because they allowed time sensitive critical analysis that was too slow and for contemporary AI to solve. 100 years from now, electrical grid management won't require another layer of sensors because the software analysis of grid fluctuations will be sufficient. On the other hand, grid managers will not remove these additional layers of sensors from the grid a hundred years from now anymore than we telephone engineers would suggest that maybe they should stop using fiber optics because they could get back to 1990 fiber optic capacity and reliability using copper wire with today's switching and software devices.
