Smart grid is mostly related to having individual appliances able to be turned off at peak load times, and giving customers a credit for doing that.
There is some worry, I think, about all the non-linear loads that draw constant power over a range of voltages. In cases of extreme shortage of generating capacity, they used to do "brownouts" where they would reduce voltage, and incandescent and heating loads would be reduced. Compact fluorescents, motors on VFDs, computers, etc. all will draw constant power during a brownout, and they look a lot less resistive also, so may be less absorptive to network instability (less damping).
