The distribution grid hasn’t been designed for charging electric vehicles

Daniel Stetter is head of Smart Energy Systems at Fraunhofer IAO Stuttgart and provides some insights on smart grids and system thinking, mobility and electricity. ‘We develop forecast based optimization for charging of electric vehicles and for energy manage-ment systems. Our software takes into account how much energy should be transferred into a car, at which point of time, while taking into account the restrictions of the energy system. This is one of the main challenges at the moment: the restrictions of the energy system and the distribution grid. In the near future, we’re going to see a lot more electric vehicles and charging points in the distribution grids. However, the distribution grid hasn’t been designed for this. Refurbishing the hardware isn’t the solution, but software is: Algorithms make sure electric vehicles can always be charged, while the distribution grid stays within safe boundaries.’
