This gets posted regularly on Lemmy, and while the economic take is tone-deaf at best, there's a real issue with generating more power than you can use. You can't just dump grid power
it needs to go somewhere. The grid needs to consume as much as it generates at all times or else bad things happen.
There are of course solutions, but that doesn't mean it's not an engineering challenge to implement.
Figuring out what to do with kilowatts is easy, but figuring out what to do with megawatts, at the drop of a hat, is substantially harder.
Why wouldn't batteries work?
Oh they absolutely do! My only point is that grid supply must equal grid demand. There are many ways to achieve this, as folks here have pointed out.
Throttling power generation (turning off/disconnecting PV from grid for example), and storage (chemical, heat, or hydro battery) are all established technologies, they just need to be implemented properly to avoid supply/demand mismatch.
