Can anyone here describe how the distribution networks coordinate with the national grid in this scenario. Is there no real coordination and in the old days it didn't matter due to a lot more inertia and heaps more reserve capacity?
Try to keep it simple!
As I understand it, the DNO's simply state what frequency their particular bit of the distribution effectively trips out at usually a degree lower than 49.5 Hz (along the lines of say 48Hz) - each of the DNO's report into the grid - from there is fairly automatic based on a nominal 1GW instant loss on the grid generation and consequent frequency droop - and an action plan to shove more power onto the bars based on fast response generation (pumped Hydro, CCGT etc) if that's feasible depending on how bad the grid frequency droop is.
