Optimization of EV-Fast Charging Station Placement for Grid Support

Electric vehicle charging stations are essential for the proceeding electrification of transportation. In particular, fast charging infrastructures cause high power demands and challenge the hosting capacity of already highly loaded distribution grids. For maximizing the grid's hosting capacity, the charging infrastructure can provide grid voltage support or mitigation of current violation of devices such as transformers. Both grid support functionalities are dependent on the placement of charging stations in the grid. This work investigates the impact of charging stations' location on the potential of these functionalities. The theoretical basis of the functionalities is introduced and an algorithm for optimized placement of fast charging stations (FCS) in the grid is introduced to maximize the hosting capacity for home charging facilities (HCFs).
