A review of key technologies for integration of electric vehicle-charging station-transportation network-grid based on bibliometric analysis

引用

Journal of Traffic and Transportation Engineering(English Edition) 2024年

作者： Hongjun Cui Xiushi Dong yue su Minqing Zhu Weimin Li Xinchang Zhang School of Civil and Transportation Engineering， Hebei University of Technology School of Architecture and Art Design， Hebei University of Technology Hebei Expressway Group Limited School of International Business， Tianjin Foreign Studies University

Electric vehicles (EVs) are instrumental in balancing the operation of the transportation networks and grids for the dual attribute of power and traffic load. Current research community has gained significant efforts on key technologies for the integration of electric vehicle-charging station-transportation network-grid (VSNGI). Therefore， a synthetic review on this domain is needed. In this context， the VSNGI research included in the Web of Science (WOS) was synthetically analyzed using bibliometric methods， the software VOSviewer and CiteSpace. The results show that the internationally interested VSNGI research is in a period of rapid development in terms of publication volume， national， institutional， and journal performance. The cited literature provided work accumulation in five aspects: “the impact and control of EVs on the grid”， “design of EV charging stations”， “integration of charging stations and grids”， “integration of charging stations and transportation networks” and “coupling of the transportation network and grid”. Then， the latest progress was summarized in four aspects: “characterization methods of spatiotemporal features of road network demand and grid load”， “SNG collaborative layout technology”， “VSN orderly guidance technology”， and “VNG interactive response technology”. Lastly， the problems and prospects in the VSNGI research were discussed. The joint efforts of researchers from multiple disciplines are required by the development of the VSNGI field. The VSNGI research will be of crucial significance in the transformation of the transportation field.

教学应对是教师面对外部发生的变化或应对外部的要求,为了处理教学实际与外界要求的矛盾、解决实践中发生的问题以及促进自身专业发展而作出的一系列认知性与行为性努力。教学应对离不开一定的实践场域,课程改革是教学应对的政策语境,督导评价是教学应对的权变情境,课堂突发事件是教学应对的生发场景。应对场域的特征会对教师的应对行为造成一定的影响,但这种影响并不是直接发生的,而是以教师的心理活动及其规律性作为中介,主要包括情境感知、对比分析以及状态生成三个环节。依据教师教学应对行为的表现形态,可将教学应对划分为一成不变、随流顺变、主动求变、相机而变四种类型。教师的教学应对究竟是积极还是消极,应置于具体情境中去观察与审视。

针对航空发动机滚动轴承的故障诊断,提出一种基于频域特征的故障诊断模型。将原始振动信号进行包络解调预处理,仅取每段数据处理后的512个点作为故障特征,将其作为双向循环长短期记忆网络(BiLSTM)模型的输入,可对内圈故障、外圈故障、滚动体故障及每种故障所对应3种不同的故障程度进行诊断。该模型不仅弥补完全由原始振动信号输入导致输入数据冗长,特征不明显等缺点,也弥补由人工提取振动特征来进行故障诊断的不确定性。在滚动轴承公开数据集上进行实验,结果表明故障识别的准确度达到99.8%以上。搭建航空轴承实验器来对方法与模型进行检验。基于频域特征的双向循环长短期记忆网络模型能够更准确地对轴承进行故障诊断,所提方法对于航空发动机滚动轴承故障诊断具有重要工程价值。
