There's pretty decent analysis of levelized costs including storage by Lazard[1].
This type of analysis is pretty difficult though. A modern grid with both solar and wind power is pretty resilient and calculating the amount of storage needed depends on the things like if it has long distance transmission lines (increasing reliance by increasing the geography).
I think this is why a lot of places end up having a gas peaker plant. In terms of running costs it's not great, and the climate impact is bad (although I guess hydrogen helps is that is available anywhere yet). But it's cheap to build ($85M gets you 55MW[2]). These days batteries are cost competitive with that though[3]:
> a 250MW, four-hour (1,000MWh) battery system in New South Wales would be a cheaper option for meeting peak demand than a 250MW new-build OCGT from both levelised cost of energy (LCOE) and levelised cost of capacity (LCOC) perspectives.[3]
