Abstract
The focus on electrification in urban public transit has been strengthened by the global shift towards sustainable transportation. A promising solution to reduce emissions and dependence on fossil fuels is electric buses. However, the widespread implementation of electric buses requires a robust charging infrastructure capable of meeting the operational demands. This work addresses many challenges and limitations facing the spread of electric buses using optimization methodologies. It includes varies parameters, which affect the planning of the required charging infrastructure such as available area, charging capacity, and optimum total costs. Also, this work examines the robustness of the charging infrastructure, where many possible failure scenarios of the components are considered. In this part, potential effects on planned routes and buses are used as an indicator for the severity of failures. Additionally, the ability of bus depots to supply ancillary services is analyzed. In this context, the advantages of implementing either load management or stationary batteries or even both are evaluated.
