Wang, L. (author), Qin, Z. (author), Wu, Y. (author), Bauer, P. (author)Reinforcement of the legacy grid infrastructure will be very costly and thereby unrealistic. Consequently, weak grid connection of electric vehicle (EV) chargers will sooner or later be the case. It may however bring instability issues since the EV chargers that can work well in strong grid conditions usually do not fit the weak grid...conference paper 2023
