I don’t think the solution to that problem though is having multiple, smaller, unconnected grids.
I think it’s to just have a more resilient grid system that doesn’t have any areas that are a single point of a failure

Take Puerto Rico and Hurricane Maria, for example. Most of the power generation was done on, I believe, the south side of the island, and they had one single high tension line running to the north side. And so when that line snapped, everybody on half the island lost power at the same time. Now I know that their power grid was very underfunded and barely staying afloat anyway, but that’s still not a good thing.

Many smaller, unconnected grids would also allow more resilience against something like solar flares as there aren’t nearly as long of wires to build up a charge over and fry things.

I think I have only had 1 power cut longer than 5 mins in the last 15 years (SE England), it’s not a big problem here. (Bigger issue in Scotland/Wales/Cornwall as they get bigger storms)
The grid already allows some areas to be cut off and others continue when there is a problem or lack of generation (see ZA load shedding for an extreme example).
I think what you are asking for is for the generation to be spread out so that everywhere is almost self sufficient, but can rely on others when they are not?
It’s a nice idea, but I don’t think it’s feasible as the economies of scale make big power plants/big offshore farms more efficient. Generation will almost always be concentrated into a small number of locations. It’s also much harder to balance load/demand on a smaller grid - if your street was a grid and had to operate off grid off rooftop solar for example how would it cope when everyone turns on the oven for dinner?

Yeah, that’s exactly what I mean is more decentralized generation as you mentioned. Here, our power is not often interrupted, but when it is, it can be for hours at a time or longer depending on how strong the hurricane or whatever that knocked it out was.
