Abstract

Electric vehicles (EVs) are an important part of future sustainable transportation. The increasing integration of EV charging stations (EVCSs) in the existing power grids requires new scalable control algorithms that maintain the stability and resilience of the grid. Here, we present such a control approach using an averaged port-Hamiltonian (pH) model. In this approach, the underlying switching behavior of the power converters is approximated by an averaged nonlinear system. The averaged models are used to derive various types of stabilizing controllers, including the typically used proportional-integral (PI) controllers. The pH modeling is showcased by means of a generic setup of an EVCS, where the battery of the vehicle is connected to an ac grid via power lines, converters, and filters. Finally, the control design methods are compared for the averaged pH system and validated using a simulation model of the switched charging station.
