Vehicle to grid and Demand Side Management — An assessment of different strategies for the integration of electric vehicles

Electric vehicles offer new possibilities for the compensation of large fluctuations caused by renewable energy feed-in. They can be integrated into the electricity grid through different strategies. This study compares non-controlled charging, Demand Side Management and Vehicle to Grid integration strategies with regard to the achievable smoothing of the residual load in the target years 2020 and 2030. Therefore, these strategies are implemented in a temporal resolved model and an indicator for the quality of compensation is developed. The analysis of the results show that significant effects can be achieved with Demand Side Management, especially in 2030. The smoothing effect of Vehicle to Grid is even stronger, although the potential of this integration strategy is not exhausted when it is used for the compensation of fluctuations.
