标题： Coordinated Charging and Discharging Strategies for Plug-in Electric Bus Fast Charging Station with Energy Storage System

摘要： 插电式电动公交车（PEB）是一种环保的公共交通方式，而插电式电动公交快充站（PEBFCS）在PEB的运营中扮演着至关重要的角色。在有效的控制下，在PEBFCS内部部署能量存储系统（ESS）可以减少峰值充电负荷和电费。为了处理（综合）调度问题（包括PEB充电和）ESS的充放电，本研究提出了一种针对配备ESS的PEBFCS的最佳实时协调充放电策略，以实现最大的经济效益。根据PEB充电负荷是否可控，相应的数学模型分别在两种场景下建立，即协调PEB充电场景和非协调PEB充电场景。模型中考虑了ESS的价格和寿命、PEBFCS的容量费用以及电价套利。进一步地，在协调PEB充电场景下，开发了一种基于启发式的计算方法，显著提高了计算效率，得到了近似最优策略。最后，我们验证了所提出的策略的有效性，解释了ESS价格对ESS使用的影响，并通过案例研究提供了ESS容量的灵敏度分析。 显示英文摘要

摘要： Plug-in electric bus (PEB) is an environmentally friendly mode of public transportation and plug-in electric bus fast charging stations (PEBFCSs) play an essential role in the operation of PEBs. Under effective control, deploying an energy storage system (ESS) within a PEBFCS can reduce the peak charging loads and the electricity purchase costs. To deal with the (integrated) scheduling problem of (PEBs charging and) ESS charging and discharging, in this study, we propose an optimal real-time coordinated charging and discharging strategy for a PEBFCS with ESS to achieve maximum economic benefits. According to whether the PEB charging loads are controllable, the corresponding mathematical models are respectively established under two scenarios, i.e., coordinated PEB charging scenario and uncoordinated PEB charging scenario. The price and lifespan of ESS, the capacity charge of PEBFCS and the electricity price arbitrage are considered in the models. Further, under the coordinated PEB charging scenario, a heuristics-based method is developed to get the approximately optimal strategy with computation efficiency dramatically enhanced. Finally, we validate the effectiveness of the proposed strategies, interpret the effect of ESS prices on the usage of ESS, and provide the sensitivity analysis of ESS capacity through the case studies.
