Reduced complexity building and heat pump model to facilitate large scale deployment evaluations

To achieve carbon neutrality by 2050, the heating sector will need to be decarbonized quickly. Heat pumps are an ideal technology for the electrification of distributed heating demand. To study the effects of large-scale introduction of heat pumps in electric energy distribution grids, it is imperative to use detailed heat pump models. At the same time, the controllability of the heat pump needs to be reflected by the simulation model.We propose a modeling paradigm, that uses thermal demand output from a detailed building model to build a simplified building and heat pump model that can be employed in time-discrete simulations with dynamic controls. The model enables large scale deployment evaluations for heat-pumps due to the low computational effort needed at simulation runtime. The complex building dynamics are decoupled from the simulation through the determination of the building thermal demand curves.The Building temperature is determined using simple thermodynamic assumptions for every simulation time step. The approach is demonstrated for heating as well as cooling systems. Results are validated by evaluating building temperature in the detailed building simulation using thermal output of the simplified heat pump simulation model as heating and cooling system.
