Optimized Operation of an Electric Vehicle DC Fast Charging Station in Combination with Storage and Photovoltaics

Schäuble, Johannes; Kühner, Johannes; Jochem, Patrick; Fichtner, Wolf

Fast charging stations significantly reduce the time to charge electric vehicles. Adequately placed, fast charging stations can enable electric vehicles to cover even larger distances by avoiding extremely long charging breaks. In this way, fast charging stations contribute to strengthen the competitiveness of electric vehicles compared to vehicles with combustion engine. However, the high load of fast charging stations may possibly have negative effects on the power grid. Operators of fast charging stations might be incentivized to adjust time and amount of purchased energy to the current state of the power grid, if it reduced energy costs for them. Energy purchasing can thus be influenced by the structure of the electricity tariff based on which energy costs are calculated. This paper examines how to minimize energy costs of a fast charging station under different conditions. In order to minimize energy costs, a stationary storage and a photovoltaic system are placed between the power grid and the fast charging station. As stationary storage, a vanadium redox flow battery is assumed. Own consumption of photovoltaic electricity reduces the amount of energy to be purchased and hence lowers energy costs. ... mehr
