Scientists at the University of Cologne are investigating how an energy system with a high share of renewables can work even in extreme weather situations.
In a climate-neutral energy system, significantly more electricity is needed, especially at low temperatures. At the same time, electricity generation is increasingly dependent on the weather because a substantially larger share of the electricity is produced from renewable energies (RE). In a recent study, researchers at the University of Cologne have shown how the security of supply can still be guaranteed in such a climate-neutral energy system – even in extreme weather situations. With the help of weather and power plant deployment models, the two doctoral students Linh Ho and Berit Hanna Czock, and Professor Dr. Stephanie Fiedler investigated the reliability of the power supply with increasing RE shares in the event of particularly extreme weather periods.
