Rooftop Solar in the US has had such requirements for a long time. More recent systems in CA like mine (IIRC starting in 2018) require an active connection to the grid operator so the operator can override the default exceedance values to permit larger excursions for longer to avoid a cascade where grid instability causes lots of solar capacity to trip, causing further instability, leading to collapse.
They can also command solar to stop providing power to the grid if there is an excess in the other direction though legally there is a limit to how often they can do that and for how much total time.

- xenadu02 1y ago> Would home storage buffers help? Yes. I actually have 20kWh battery storage on my home. It provides backup power and covers our needs during hours of peak pricing. In theory NEM3 in California was supposed to encourage installation of battery storage but was instead a give-away to utilities because they never actually implemented any reasonable benefits. Under NEM3 they force you to give away electricity to utilities essentially for free so now solar only makes sense if you have storage deployed with it.
