I suggest that causing a cascade effect and increasing the area of an outage isn't a good way to design a system.
I suggest that you don't understand power distribution and transmission very well. Just like any other generator, if you load a power station too heavily, the voltage and the frequency will both be pulled down. Since the tolerances on public electricity are something like +-5v and +- .5 Hz., they really have no choice but to break ties when a plant or segment goes out. They really shouldn't cross-tie power on a running basis as much as they probably do... but since the Green folks won't always let them build plants...
