The share of fluctuating renewable energies in Germany’s electricity generation has risen sharply in recent years and is likely to increase further. This results in stronger fluctuations in the price of electricity and a higher frequency of situations in which potential electricity production exceeds demand, so that power plants on the basis of fluctuating renewable energies have to be shut down. In order to address these issues, measures that enable flexible handling of a fluctuating energy provision are increasingly needed. Power-to-Heat—the conversion of electrical into thermal energy—represents such a measure. In this work a decentralized power-to-heat approach is considered, which includes the installation of heating cartridges in the heating systems of end customers. In order to influence the supply situation considerably with such small-scale systems, a coordinated operation of a large number of these plants is required. Therefore, in this paper a control concept is developed and presented, which should enable such a coordinated operation. Various elements are integrated into the control concept which should ensure a high degree of predictability of the operation despite given uncertainties (e. g. forecast errors). In conclusion, some aspects of the concepts are evaluated using simulations.
