In this project – financed by the German Federal Ministry of Economics and Technology – medium to long-term prospects of plug-in electric vehicles (full electric and hybrid) were analysed in a supply system with a high share of renewable energy sources. Prerequisites for a successful technology and market development of plug-in vehicles were analysed in different scenarios. User profiles were derived from today's real world driving profiles and used for calculating the resulting electricity demand as well as the grid-connected battery capacity of the vehicle fleet in hourly resolution. Resulting information on the available capacity for load-balancing in the power distribution system was integrated into an energy system model which analyses economically optimized supply systems. The model was applied to simulate load coverage over time by renewable sources of energy, controllable CHP and condensing power plants, stationary and mobile storages as well as by power transmission in the power grids of Europe. This scenario analysis shows the potential of the controlled charging of vehicle batteries for load balancing in comparison to other balancing options. Further model based analyses were focussed on the grid integration of electric mobility and synergistic effects with decentralised power generation on different levels, i.e. domestic energy supply, distribution networks and the national transmission network. Main focus was the effect of electric mobility on the network expansion required in the future.
