This paper considers integration of heat pumps in Danish low-voltage residential power distribution network, hereafter referred to as “radial”, providing a data-driven case study for the electrical package of the Modelica Buildings library. The loads in the distribution grid for year 2030 are estimated based on the requirement of fully sustainable energy system by the year 2050. Combined with local consumption, the total system model is validated by measuring mains transformer signal at the chosen radial. The maximum cable capacity is compared to future current flow estimations for a 2030 grid, simulated based on a specific official Danish scenario. The study shows, that there is no threat to the network cables, if only heat pumps are integrated. However, when maximum load is applied to the grid, the values of cable currents are relatively close to the limit, which may complicate integration of other technologies. The results point at recommendations for safety measures to protect electric lines during periods of rapid technological development.
