Abstract: This paper focuses on the influence of increased wind and solar power produc-
tion on the transmission networks in Central Europe. The German Energiewende
policy together with insufficient transmission capacity between northern and south-
ern Germany as well as the existence of the German-Austrian bidding zone heavily
contribute to congestion in the Central European transmission system. To assess
the exact impact on the transmission grid, the direct current load flow model
ELMOD is employed. Two development scenarios for the year 2025 are evaluated
on the basis of four representative weeks. The first scenario focuses on the effect
of Energiewende on the transmission networks, the second one drops out nuclear
phase-out and thus assesses isolated effect of increased feed-in. The results indi-
cate that higher feed-in of solar and wind power increases the exchange balance
and total transport of electricity between transmission system operator areas as
well as the average load of lines and volatility of flows. Solar power is identified
as a key contributor to the volatility increase, wind power is identified as a key
loop-flow contributor. Eventually, it is concluded that German nuclear phase-out
does not significantly exacerbate mentioned problems.
