The easiest way may be to go to DC then generate the nice stable sinusoidal mains frequency from that, but its not necessarily the most efficient.
My thinking is that FFs would be installed in clusters, and they could be shut off or cranked up as 5MW units. That’s a small enough slice to smoothly match rises and falls in demand, I think. That way each unit would have a constant pulse rate, so no need to fiddle the frequency!
