中文摘要
摘要 电动-自动驾驶灵活公交(EAB)在提供高效且响应需求的公共交通服务方面展现出巨大潜力,但在充电规划和能源管理方面也带来了挑战。本研究提出一种灵活的公交运营模型,作为传统固定线路终点站充电方式的替代方案。通过构建一系列情景,评估在结合分时电价机制、快速充电站(FCS)与储能系统(ESS)集成部署以及实施峰值电压管理(PVM)策略的情况下系统的运行性能。结果表明,相较于出现显著负荷尖峰的基准情景,采用PVM策略可有效将电网峰值功率降低22.2%。然而,这种峰值削减是以延长充电时间及降低利用效率为代价的。相比之下,基于ESS的情景相比PVM情景缩短了8.9%的充电时间,并使目标函数值提升了60.6%,这主要归因于ESS运行所带来的收益。但该配置也会因ESS自身充电行为而引发新的电网功率尖峰。联合部署ESS与PVM策略能够有效缓解这一问题,进一步使与ESS相关的利润提升8.4%,并提供一种更具可持续性和经济可行性的解决方案。此外,本研究还探讨了ESS容量对系统性能的影响,发现EAB的灵活按需服务模式为合理配置ESS及有效实施PVM策略提供了有力支撑。
English Abstract
Abstract Electrified-autonomous flexible buses (EAB) offer promising potential for delivering efficient and demand-responsive public transit services but pose challenges in charging planning and energy management . This study proposes a flexible bus operation model as an alternative to the conventional fixed-route terminal charging approach. A series of scenarios is developed to assess system performance under the integration of fast charging stations (FCS) and energy storage systems (ESS), in conjunction with a time-of-use electricity pricing scheme and the implementation of peak voltage management (PVM) strategies. The results demonstrate that the PVM strategy effectively reduces grid peak power by 22.2 % compared to the baseline scenario, which exhibits pronounced load spikes. However, this peak reduction comes at the cost of extended charging durations and diminished utilization efficiency. In contrast, the ESS-based scenario reduces charging time by 8.9 % relative to the PVM scenario and enhances the objective function by 60.6 %, primarily due to revenue generated through ESS operation. Nonetheless, this configuration introduces a new sharp peak in grid power associated with ESS charging. The combined deployment of ESS and PVM effectively mitigates this issue, further increasing ESS-related profits by 8.4 % and offering a more sustainable and economically viable solution. In addition, this study explores the impact of ESS capacity on system performance and finds that the flexible on-demand service model of EAB provides strong support for arranging the ESS and the implementation of PVM.
