We've seen a number of recent 'blackouts' where the split between forming and following generation has become unbalanced forcing the following equipment to (in some senses) "trip too soon".
I'm looking for the a readable source of the regs/specs, and distinctions between, the two nominal types of generation, possible with a discussion of how the grid system has migrated over the years to the current state.
The 'holding' capability is speculative on my part... Given that we now have much more 'renewable' generation that is electronically controlled it does feel as if there has become a fillable gap in between these two simple control techniques that would utilise the flexibility of electronic control to 'beat' the old limitations of rotational inertia and Lenz's law to "Hold up" the grid in a more positive way rather than tripping too soon (given it's alternative storage capabilities) and bringing down the local grid.
Are there available on-line the Grid Forming & Following specs/regs?
