Smarte Anreizsysteme sorgen für effiziente Nutzung der Ladeinfrastruktur
Smart incentive systems ensure the efficient use of charging infrastructure.
In the BeNutz LaSA project - Better use of charging infrastructure through smart incentive systems - the FCN team, together with partner institutes from RWTH Aachen University, SMART/LAB Innovationsgesellschaft and the eRoaming platform Hubject, is investigating whether and how users of electric vehicles can be motivated to use the existing charging infrastructure depending on its current capacity utilization through smart, price-based incentive systems. On the one hand, the aim is to equalize the use of heavily utilized charging stations over time and, on the other, to avoid overloads in distribution networks.
BeNutz LaSa uses big data methods and machine learning to forecast the utilization of charging infrastructure and distribution grids over time. In this context, the Aachen Institute for Power Electronics and Electrical Drives (ISEA) is responsible for forecasting the capacity utilization of the charging stations. The Institute for Electrical Systems and Grids, Digitization and Energy Economics (IAEW; also at RWTH Aachen University) is working on the forecasting and evaluation of power flows as a result of charging processes in the distribution grid. Recognized patterns are used to predict possible charging peaks. Ultimately, the probability of each individual charging station being occupied during the forecast period is calculated.
On this basis, the FCN-ECO researchers design strategies for dynamic prices, which are passed on to the charging infrastructure by SMART/LAB and Hubject. The prices are adjusted for specific charging stations according to the respective capacity utilization in order to shift flexible charging processes to periods when charging stations and distribution networks are less busy. Ultimately, this means that charging stations are better utilized and grid overloads are avoided.
In this project, FCN-ECO is also investigating whether and under what conditions and to what extent drivers of electric vehicles are at all willing to change their charging behavior in terms of time and possibly also space if appropriate price incentives are set.
