According to the article it was a cascade of events and the last one was the 244MW gas turbine going out that lead to the collapse so not that far from current scale grid batteries.

Also battery reacting instantaneously to correct or mitigate a grid issue might avoid some other generator to go offline or allow to go offline for a must shorter amount of time avoiding some of the cascading effects.

It seems to me that the value of grid batteries is not just the nameplate capacity compared to other generation technologies, it is a class on its own.

May be once batteries are incorporated in the grid at some scale software triggers commanding other generators capacity disconnect/reconnect will have to be updated "let the grid batteries do their job first and then act".
