Not islanding, overproduction, where the grid owner is trying to accurately manage decreasing production to match need. Solar is more difficult for this as when a grid is largely solar the local producers and grid producers will tend to have simultaneous excess and need in synchronous day/night cycles, so the grid operator would need as much accurate and real time data as can be had so that they would know how much and when to charge batteries or to otherwise dispose of unneeded waste electricity for their local area.
