Integration of surplus wind energy by controlled charging of electric vehicles

Electric vehicles in combination with intelligent charging algorithms are widely accepted to have the potential to enhance the share of renewable energies in the power system. Since wind energy is one of the most important renewable power sources in Germany, this paper projects available wind energy in the German transmission grid until 2030 and shows the ability of different electric vehicle fleet sizes to absorb surplus wind energy with respect to technical limits of the grid. Therefore, a model representing the German transmission grid in 2020 and 2030 has been built and different charging strategies have been applied. The results indicate that electric vehicle fleets have the potential to enhance the integration of wind energy in the transmission grid.
