Synergies and Conflicts of Integrating Electromobility and Renewable Energies into the Urban Micro Grid at Train Station Berlin Sudkreuz

摘要

For the Intelligent Mobility Station Berlin Sudkreuz simulation-based optimization identified conflicts and synergies of integrating electromobility and renewable energy into a micro grid. Results show that the increase of autonomy is proportional with battery capacity used for storing excess energy. Optimization shows that renewable energy generation and their appropriate curtailment should be preferred. However, it can ultimately lead to overall system life cycle emissions comparable to those of the partly fossil energy mix from the public grid. Consequentially we derive general proposals of how to optimally combine storing, curtailing and feeding-in of renewable energy in a local micro grid with electromobility.
