Abstract: Electrification poses a promising approach to reducing carbon emissions and promoting carbon neutrality in the transportation sector. Along the transportation electrification pathway, the goal of carbon neutrality can be further accelerated with an increasing amount of electricity being generated from renewable energies. A massive number of electric buses have been employed and operated in dozens of metropolises worldwide. An important daily operations issue with these urban electric buses is how to coordinate their charging activities in a cost-effective manner, considering various physical, financial, institutional, and managerial constraints. This talk discusses scheduling the daily charging activities of an electric bus fleet operated across multiple bus lines and charging depots and terminals, with the aim of finding an optimal set of charging location and time decisions given the available charging windows, with the electricity supplied by the conventional power grid and emerging photovoltaic-storage-charging stations. A real-world regional electric bus fleet of 122 buses in Shanghai, China is selected for validating the effectiveness and practicability of the proposed charging scheduling models and algorithms.
