Heat pumps and charging stations should be able to be dimmed in order to ensure reliable operation of the distribution grids in critical grid situations. The communication required for this runs via the CLS channel of the smart meter gateway. The UtiliSpaces project has now been launched at Fraunhofer ISE in Freiburg, which aims to research the existing challenges of implementation in this complex environment in practice. The project is funded by the German Federal Ministry of Education and Research with a grant of 2 million euros and coordinated by Fraunhofer IEE.
