Optimal Location and Sizing of Electric Bus Battery Swapping Station in Microgrid Systems by Considering Revenue Maximization
Özet
The radical increase in the popularity of electric vehicles (EVs) has in turn increased the
number of associated problems. Long waiting times at charging stations are a major barrier to the widespread
adoption of EVs. Therefore, battery swapping stations (BSSs) are an efficient solution that considers short
waiting times and healthy recharging cycles for battery systems. Moreover, swapping stations have emerged
as a great opportunity not only for EVs, but also for power systems, with regulation services that can be
provided to the grid particularly for small networks, such as microgrid (MG) systems. In this study, the
optimum location and size that maximize the revenue of a swap station in an MG system are investigated.
To the best of our knowledge, this study is first to solve the placing and sizing problem in the MG from
the perspective of a BSS. The results indicate that bus 23 is the BSS’s optimal location and is crucial for
maximizing revenue and addressing issues like the provision of ancillary services in microgrid system.
Finally, the swap demand profile of the station serving electric bus public transportation system was obtained
using an analytical model based on public transportation data collected in Berlin, Germany.
