Grid-friendly integration of charging infrastructure into an urban power distribution network

In this paper, different approaches are presented, based on which a grid-friendly charging of electric vehicles in the local distribution network can be implemented. Two current projects are discussed in more detail. On the one hand, a centralized approach is used here. On the other hand, a decentralized, autonomous solution in the local low-voltage network is being investigated. All the projects presented are tested in the context of field tests, with the aim of converting these approaches into real use if possible after the end of the project. In addition, the current discussion on smart meter gateway technology in Germany has a strong influence on the communication concepts of these solutions.
