The increased number of electric vehicles along with the traditional grid infrastructure cause challenges for the electric power system especially due to high electricity demands from the electric vehicle charging. Data-driven charging strategies can help to overcome grid problems and integrate electric vehicles more smoothly. In this project the value proposition of smart charging will be evaluated with data-driven techniques in both regions, BY and CA, based on two different perspectives: a) wholesale prices on transmission level and b) time-of-use rates on distribution level. An interplay between those two scopes will be explored in order to suggest best practices, strategies, and policies for each region. Thereby, the expertise in the field of data-driven optimization and simulation play an important role. The expected output of this study is to explore ways of estimating the value of smart charging based on cost savings at the distribution and transmission level.
Final report:
The Bavaria California Technology Center (BaCaTeC) sponsored the early engagement between the Professorship for Energy Informatics at FAU and the two research institutions, the Stanford Linear Accelerator Center (SLAC) at Stanford University and the Transportation Sustainability Research Center (TSRC) at UC Berkeley.
The sponsored cooperation enabled the scientific partners to spend time in Bavaria as well as in California. Dr. Apostolaki-Iosifidou was a Visiting Scientist at FAU in August 2019. Her stay included participation in workshops and intensive sessions to develop ideas for follow-up projects within the TSRC Total Charge Management (TCM) project and the intelligent grid integration of electric vehicles. This resulted in a publication [1] that was published in the Journal Energies. Dr. Lipman was a Visiting Scientist at FAU in October 2019. Mr. Lipman taught a half-day workshop and gave interesting insights into various projects of the TSRC. Furthermore, we worked on further ideas for follow-up projects within the TCM project. In March 2020, Prof. Pruckner planned a research stay of several weeks at the two research institutes in California, which had to be shortened to nine days due to the Covid pandemic. Nevertheless, it was possible to work on a further publication [2] and to establish further contacts at Stanford University and UC Berkeley. These contacts will be used for further research projects in the near future.
