There are a lot of interesting Demand Response solutions that are also somewhat applicable/useful for this problem. In a normal demand response scenario, when too many people are demanding energy, certain loads are turned off or scaled back (ACs/Thermostats/Water Heaters). Water heaters in particular have been shown to have been one of the better time shifting solutions. Seems like you could do the same thing with both water heaters and AC systems as most buildings have quite large thermal masses. For AC its a bit lame because the hottest time of the day is the best producing for PV frequently so shifting can be tough, but perhaps around the beginning of the day and end of the day there is some opportunity to precool homes before people return and then back off as the price goes above 0, that sort of thing.
