Integrating Decentralized Electrically Powered Thermal Supply Systems into a Smart Grid

The goal of the project “Smart Region Pellworm” is the establishment and operation of a smart grid with a hybrid energy storage system on the German island of Pellworm.One part of the project is the integration of power-to-heat appliances into the smart grid for demand side management purposes.Thispaper deals with the prerequisites and lessons learned from the integration of electric night storage heaters into Pellworm's energy management system. Special focus lies on the development of a heat demand prediction model.
