IAEE European Conference 2017: Relieving the German transmission grid with regulated wind power development

Publication and presentation: "Relieving the German transmission grid with regulated wind power development" at the 15th IAEE European Conference 2017, Vienna, 6. September 2017

The expansion of capacities in the German transmission grid is a prerequisite for the further integration of renewable energy sources (RES) into the electricity sector.

Within the research project MONA 2030, the simulation model ISAaR is applied in order to assess various grid optimisation measures. These measures are compared and contrasted with conventional grid expansion scenarios and assessed as alternatives to grid upgrades.

This paper evaluates an approach to relieve the German transmission network by regulating wind power development, which will decrease the necessity for increasing transmission capacities or the demand for other grid optimisation measures. In the scenarios, wind turbines are installed in central and southern Germany instead of onshore and offshore sites the wind-swept north. Hereby, the generated amount of energy is held constant. Due to the poorer quality of locations in central/southern Germany, the installed capacities and consequently the required investment increases. However, advantages with respect to congestion management can be achieved.
