In many new development areas, the residential buildings there use heat pumps exclusively for heating and domestic hot water supply, which—particularly in predominantly heat-led operating modes—can lead to a high load on the electrical distribution grids. The focus of this work is therefore on the energy system of a heat-pump-heated single-family house whose electrical and thermal energy demand is met, on a balance-sheet basis, 100% from renewable sources. Battery and thermal storage systems help to integrate the fluctuating availability of renewable energy generation into the building energy system.

The overarching objective is to investigate the influence of electrical and thermal storage capacities on the load on the electrical distribution grid in heat-pump-heated single-family houses. From this, three research questions are derived, which address (1) the influence of the renewable energy generation mix and (2) the mutual interaction of the thermal and electrical storage capacities employed, and (3) examine the contribution of storage capacities dimensioned according to current planning principles to relieving the grid.
