Abstract

Transitioning toward non-polluted public transportation systems is crucial for sustainability. Although declining battery costs have led to a greater utilization of battery-powered electric buses (BEBs), challenges persist owing to the high cost of chargers and battery energy limitations, which require efficient solutions. Therefore, this study proposed a novel offline state-of-charge scheduling method that focuses on optimizing battery and charger capacities. To make this study applicable to any city, a precise bus dynamic model was developed, and all evaluations were conducted using data commonly available in the cities. To validate the optimization, a sensitivity analysis was conducted to represent the effects of the factors involved. Moreover, to investigate the differences between the utility service and depot owner perspectives, the city’s and synthetic electricity tariffs were employed for scheduling, which differ in covering the city’s daily load profile valleys. This measure is crucial when the BEB demand is not considered in generation.

转换电池驱动的公共汽车：充电状态调度与电池和充电器容量优化的合作

向无污染的公共交通系统过渡对于可持续发展至关重要。虽然电池成本的下降使得电池驱动电动公交车（BEB）的使用率不断提高，但由于充电器成本高昂和电池能量有限，挑战依然存在，这就需要高效的解决方案。因此，本研究提出了一种新颖的离线充电状态调度方法，重点是优化电池和充电器的容量。为了使这项研究适用于任何城市，我们开发了一个精确的公共汽车动态模型，并使用城市中常见的数据进行了所有评估。为了验证优化结果，还进行了敏感性分析，以体现相关因素的影响。此外，为了研究公用事业服务和车厂业主观点之间的差异，在调度时采用了城市电价和合成电价，这两种电价在覆盖城市日负荷曲线谷值方面存在差异。在发电过程中不考虑 BEB 需求时，这一措施至关重要。

期刊介绍： Transportation Research Part D: Transport and Environment focuses on original research exploring the environmental impacts of transportation, policy responses to these impacts, and their implications for transportation system design, planning, and management. The journal comprehensively covers the interaction between transportation and the environment, ranging from local effects on specific geographical areas to global implications such as natural resource depletion and atmospheric pollution. We welcome research papers across all transportation modes, including maritime, air, and land transportation, assessing their environmental impacts broadly. Papers addressing both mobile aspects and transportation infrastructure are considered. The journal prioritizes empirical findings and policy responses of regulatory, planning, technical, or fiscal nature. Articles are policy-driven, accessible, and applicable to readers from diverse disciplines, emphasizing relevance and practicality. We encourage interdisciplinary submissions and welcome contributions from economically developing and advanced countries alike, reflecting our international orientation.
