The increasing numbers of electric vehicles is an ongoing trend in Germany and poses new challenges to the electric grid. This paper evaluates possible charging points and concepts for an existing distribution network to provide a suitable infrastructure for electric vehicles. The distribution network is part of a self-reliant quarter of Technische Universität Darmstadt. A simulation model of this campus area has been implemented based on recorded load profiles and data provided by the grid operator. An expansion plan for the campus area is taken into account in order to ensure a sustainable planning of the future grid structure. Furthermore, the development of electromobility is analyzed and the estimated values up to the year 2050 are transferred to the situation at the campus. Two integration concepts, a centralized one and a decentralized one, are introduced and compared. The two concepts are compared regarding the loading, the voltage range and the power balance.
