Not really. This is actually a primary design consideration taken very seriously at nuke plants. The same can NOT be said about the rest of the grid, and renewable generation facilities.

Yeah, because they're so dangerous.

If you're worried about the grid, you were always worried. We use a grid now, and in the past. Massive near-continent wide failures happened before major renewable use.

Protecting single facilities is very hard, protecting an entire grid seems impossible. Ild hope for a decentralized grid where every generator, user, and conveyer of electricity was assumed to potentially be a subverted actor. But that seems super hard.
