It gives an overview of the German and European power system operation from a preparation stage to a real-time operation as a successful practice of the solar eclipse.
The problem-free operation of the German energy supply system with about 37 GWp of installed PV capacity during the solar eclipse shows that the integration of renewable energies into the supply system has already made great progress. The European case described in this report demonstrates that with high awareness and international communication the impact on an energy supply system, and the available and needed measures to safely operate it during the event, can be successfully estimated. The lessons learned described here might be a guide for upcoming events with even higher penetration of PV.
