The OPF problem solves for an optimal dispatch at a particular point in time. A battery is an energy storage device that can operate across time. So, you have some pretty fundamental gaps to bridge, probably starting by implementing a multi period OPF. I suggest you search the list archives for previous posts about multiperiod OPF.
