A quick search turns up this reference, for some cases.
https://minds.wisconsin.edu/handle/1793/57916 .
My gut tells me it will be very hard to stay in LP but I haven't really made a deep search.
Good luck !

you can add a cost for charging and discharging. In this way, the LP solver won't use them at the same time.
Especially when the charging/discharging of efficiency are not 1.
There is only one case that it might not be resolved: when you have some wind /solar resources and you have some kind of penalty for wind curtailment. The algorithm will use charging ad discharging at the same time to dissipate the excessive wind.
