Abstract: The expansion of renewable energies (RE) is essential for achieving the climate targets set by the European Union (EU). The fluctuating feed-in from RE poses challenges for the power grid. Power-to-heat systems and particularly heat pumps can help to successfully match demand to generation. However, an appropriate control system is necessary for this approach. In this paper, a model predictive control (MPC) approach is investigated on a simulation basis. It is analyzed how the operating times of heat pumps in multi-family houses in the Greater Region (GR) can be shifted to the most economical times. For this purpose, potential flexible tariffs for the year 2030 are used. The results show a potential that can aid the grid and lead to financial savings for the end user in the GR. By using the MPC, monetary savings of up to 10 % can be achieved compared to a classical control. Furthermore, the median of the effectively used electricity prices could be reduced by up to 4.3 Cents/kWh in Germany and Belgium.
