Harmonization of Electric Mobility and Distributed Energy Networks

The increasing market share of electric vehicles and the deployment of renewable energies gives rise to new challenges regarding both the energy network infrastructure as well as mobility. The solution of the arising problems allows for synergies among these fields. The batteries of electric vehicles can be used as distributed energy storage systems to retain the stability of the energy network. To ensure the availability of the latter in the network, the vehicles must stay connected for a certain time intervals. As the batteries may also be unloaded, this leads to a paradigm change in contrast to the available concepts. In a first step, existing charging stations could be used for this purpose. To access the battery as a storage continuously, inductive load systems could be installed in the streets. Here, deployment of the latter on motorways would simultaneously eliminate the problem of range of electric vehicles. A necessary requirement for such a combined traffic and energy system is a distributed control mechanism. The goal of this article is to show possibilities to reduce the necessary coordination while still retaining stability of the overall system.
