The unIT-e² research project is moving from the laboratory phase to the practical phase. In the project’s subcluster called Harmon-E, test subjects have now been successfully equipped with a digital grid connection consisting of SMGW and HEMS. This means that the controllable grid connection can now be tested in real-world operation within the context of Section 14a. The project expects this to yield new insights into the necessity of control interventions and to provide valuable information for grid monitoring.
