Yes, that is in fact exactly what the original article is arguing - that the stability of the Western Australian grid requires a switch to "smart" solar which the grid operator can remotely curtail the output of on demand. Hence all the rhetoric about how excess power "spilled uncontrolled" onto the grid which the previous comment complained about.

This is also not, in fact, a good situation to be in. The stability of the power grid depends on balancing supply with demand in real time, and if that can't be done then the whole thing fails. Not only that, the old-fashioned gas and steam power plants have inertia that helps stabilize the grid and as that decreases overall stability margins fall. I think wind farms can emulate this inertia to a certain extent, but that doesn't always seem to work so well...
