Embodiment
[0154] This embodiment uses the historical observation data of a city's electric bus hybrid charging station, including the timetable for entering and exiting the station, and the remaining power when the vehicle entered the station for 60 consecutive days in the past (a total of 1080 valid data). In order to conduct experiments in a real environment, a total of 18 vehicles were selected initially, covering 6 different bus lines (3 vehicles per line): 791, D16, 719, 84, 129 and 792; They are: 20:20, 21:00, 21:00, 21:20, 22:00 and 22:00; departure times are: 5:00, 7:00, 5:00, 5:20, 5 :00, and 6:00.
[0155] The relevant parameters are set as follows. The planning window is from 20:00 of the current day to 7:00 of the next day, and the time step is Δt=20 minutes, so T max =34. Fault tolerance rate, that is, the probability that the existence constraint is not satisfied is ε(Γ)=0.01, and the values of other parameters are as follows: I max =12, M=10, Cap=240kWh, P=60kW, R ...
