Description
Summary:Public transportation, such as buses, depends mostly on fossil fuels, which results in significant environmental and health issues, especially for cities with high altitudes. The integration of electric buses (EBs) has been carried out as one of the alternatives to electrify public transportation. Although EBs will help to overcome these issues, a massive penetration of EBs will also lead to several technical issues. Moreover, their challenges compared to typical electric vehicles (EVs) are more complex due to the lack of flexibility and temporal correlation of scheduling for public transportation. This paper studies the effect of charging EBs in a bus station in the power load, and proposes a new methodology considering EB aggregators to minimize electricity costs while meeting grid constraints. Moreover, a sensitivity analysis is performed to evaluate the impact of the number of EB chargers in the charging costs.
