18 Summary Organizing the set of deliverables into four demonstrators proved to be advantageous in several regards: The complexity of the demonstrators became manageable Country, history and application specific aspects could be treated in a focused way The co-ordinated Internet interaction of the four demonstrators via a DSO turned out to be a promising approach for energy management in smart grids Quantifying the interaction between fleets of electric vehicles allows to plan future grid infrastructures based on reliable EVSE load characteristics helps to avoid overengineered grids and hence unnecessary cost for grid re-construction
