Model a heat pump with a buffer storage

Hello everyone,

I’m trying to model a heat pump with a buffer storage tank in Ladybug Tools / Honeybee.
My main goal is to use the buffer tank to flatten the load profile of the heat pump, but I’m not fully sure how to set up this system configuration in LBT/EnergyPlus.

Does anyone have experience with this or example workflows showing how to properly connect a heat pump with a buffer tank, especially for load-shifting or load-smoothing purposes?
