A novel MILP model for the decarbonization of transit bus system considering emissions reduction targets and distributed energy resources Kharouf, Mohammad
Abstract
Emission reduction targets are currently being set by governments to usher in a transition into clean and sustainable transportation sector. Over the past few decades, even though battery electric bus systems have been gaining popularity as a good candidate for facilitating this transition, municipalities and transit bus operators have been facing major challenges in transforming their fossil fueled fleets into battery electric such as the limited range offered by battery electric buses and their extended charging time which may adversely affect transit operations and level of service. Moreover, electric utilities are being exposed to noticeable challenges in terms of power quality (i.e., undervoltage) and high power demand as a result of this transition. These challenges force utilities to expand their distribution network which will have significant cost and environmental impact. Based on an extensive review of the research articles that aimed to address these challenges, this work proposes a novel mixed integer linear programming model that specifies the optimal sizing and allocation of on-board batteries, fast chargers, energy storage systems and renewable energy resources while maintaining current operation schedules, number of buses, interlining capability as required by the transit operators. Moreover, the developed model accounts for power distribution network constraints, battery characteristics and emission reduction goals while minimizing the emissions tax and total utility charges. The results show the capability of the proposed model to decarbonize bus transit networks on-demand by considering incremental emission reduction targets. Capital expenditure is shown to be minimized to the best interest of cities considering both transit and electricity infrastructure perspectives.
