The rapid proliferation of electric vehicles (EVs) presents both opportunities and challenges for the electrical grid. While EVs offer a promising avenue for reducing greenhouse gas emissions and dependence on fossil fuels, their uncoordinated charging behavior can strain grid infrastructure, thus creating new challenges for grid operators and EV owners equally. The uncoordinated nature of electric vehicle charging may lead to the emergence of new peak loads. Grid operators typically plan for peak demand periods and deploy resources accordingly to ensure grid stability. Uncoordinated EV charging can introduce unpredictability and variability into peak load patterns, making it more challenging for operators to manage peak loads effectively. This paper examines the implications of uncoordinated EV charging on the electric grid to address this challenge and proposes a novel dynamic optimization algorithm tailored to manage EV charging schedules efficiently, mitigating grid power peaks while ensuring user satisfaction and vehicle charging requirements. The proposed “Proof of Need” (PoN) charging algorithm aims to schedule the charging of EVs based on collected data such as the state of charge (SoC) of the EV’s battery, the charger power, the number of connected vehicles per household, the end-user’s preferences, and the local distribution substation’s capacity. The PoN algorithm calculates a priority index for each EV and coordinates the charging of all connected EVs at all times in a way that does not exceed the maximum allocated power capacity. The algorithm was tested under different scenarios, and the results offer a comparison of the charging power demand between an uncoordinated EV charging baseline scenario and the proposed coordinated charging model, proving the efficiency of our proposed algorithm, thus reducing the charging demand by 40.8% with no impact on the overall total charging time.
电动汽车(EV)的迅速普及为电网带来了机遇和挑战。虽然电动汽车为减少温室气体排放和对化石燃料的依赖提供了一条大有可为的途径,但其不协调的充电行为会给电网基础设施造成压力,从而给电网运营商和电动汽车车主同样带来新的挑战。电动汽车充电的不协调性可能会导致出现新的高峰负荷。电网运营商通常会对高峰需求期进行规划,并相应地部署资源,以确保电网稳定。不协调的电动汽车充电会给高峰负荷模式带来不可预测性和可变性,使运营商更难以有效管理高峰负荷。本文研究了电动汽车充电不协调对电网的影响,以应对这一挑战,并提出了一种新颖的动态优化算法,用于有效管理电动汽车充电计划,在缓解电网用电高峰的同时确保用户满意度和车辆充电要求。所提出的 "需求证明"(PoN)充电算法旨在根据收集到的数据(如电动汽车电池的充电状态(SoC)、充电器功率、每户联网车辆数量、最终用户的偏好以及当地配电变电站的容量)来安排电动汽车的充电。PoN 算法为每辆电动汽车计算一个优先指数,并以不超过最大分配电力容量的方式协调所有已连接电动汽车的充电。该算法在不同场景下进行了测试,结果比较了未协调的电动汽车充电基线场景和提议的协调充电模式之间的充电电力需求,证明了我们提议的算法的效率,从而将充电需求降低了 40.8%,且对总体总充电时间没有影响。

Traffic sign detection plays a pivotal role in autonomous driving systems. The intricacy of the detection model necessitates high-performance hardware. Real-world traffic environments exhibit considerable variability and diversity, posing challenges for effective feature extraction by the model. Therefore, it is imperative to develop a detection model that is not only highly accurate but also lightweight. In this paper, we proposed YOLO-ADual, a novel lightweight model. Our method leverages the C3Dual and Adown lightweight modules as replacements for CPS and CBL modules in YOLOv5. The Adown module effectively mitigates feature loss during downsampling while reducing computational costs. Meanwhile, C3Dual optimizes the processing power for kernel feature extraction, enhancing computation efficiency while preserving network depth and feature extraction capability. Furthermore, the inclusion of the CBAM module enables the network to focus on salient information within the image, thus augmenting its feature representation capability. Our proposed algorithm achieves a mAP@0.5 of 70.1% while significantly reducing the number of parameters and computational requirements to 51.83% and 64.73% of the original model, respectively. Compared to various lightweight models, our approach demonstrates competitive performance in terms of both computational efficiency and accuracy.
交通标志检测在自动驾驶系统中起着举足轻重的作用。检测模型的复杂性需要高性能的硬件。现实世界的交通环境呈现出相当大的可变性和多样性,给模型的有效特征提取带来了挑战。因此,当务之急是开发一种既高度准确又轻便的检测模型。在本文中,我们提出了一种新型轻量级模型 YOLO-ADual。我们的方法利用 C3Dual 和 Adown 轻量级模块来替代 YOLOv5 中的 CPS 和 CBL 模块。Adown 模块可有效减少下采样过程中的特征损失,同时降低计算成本。同时,C3Dual 优化了内核特征提取的处理能力,在保持网络深度和特征提取能力的同时提高了计算效率。此外,CBAM 模块的加入还能使网络关注图像中的突出信息,从而增强其特征表示能力。我们提出的算法实现了 70.1% 的 mAP@0.5,同时大幅减少了参数数量和计算需求,分别为原始模型的 51.83% 和 64.73%。与各种轻量级模型相比,我们的方法在计算效率和准确性方面都具有竞争力。

Path planning algorithms are crucial components in the process of smart parking. At present, there are many path planning algorithms designed for smart parking. A well-designed path planning algorithm has a significant impact on the efficiency of smart parking. Firstly, this paper comprehensively describes the principles and steps of four types of path planning algorithms: the Dijkstra algorithm (including its optimized derivatives), the A* algorithm (including its optimized derivatives), the RRT (Rapidly exploring Random Trees) algorithm (including its optimized derivatives), and the BFS (Breadth First Search) algorithm. Secondly, the Dijkstra algorithm, the A* algorithm, the BFS algorithm, and the Dynamic Weighted A* algorithm were utilized to plan the paths required for the process of smart parking. During the analysis, it was found that the Dijkstra algorithm had the drawbacks of planning circuitous paths and taking too much time in the path planning for smart parking. Although the traditional A* algorithm based on the Dijkstra algorithm had greatly reduced the planning time, the effect of path planning was still unsatisfactory. The BFS (Breadth First Search) algorithm had the shortest planning time among the four algorithms, but the paths it plans were unstable and not optimal. The Dynamic Weighted A* algorithm could achieve better path planning results, and with adjustments to the weight values, this algorithm had excellent adaptability. This review provides a reference for further research on path planning algorithms in the process of smart parking.
路径规划算法是智能停车过程中的重要组成部分。目前,为智能停车设计的路径规划算法有很多。设计合理的路径规划算法对智能停车的效率有着重要影响。首先,本文全面介绍了四种路径规划算法的原理和步骤:Dijkstra算法(包括其优化导数)、A*算法(包括其优化导数)、RRT(快速探索随机树)算法(包括其优化导数)和BFS(广度优先搜索)算法。其次,利用 Dijkstra 算法、A* 算法、BFS 算法和动态加权 A* 算法来规划智能停车过程所需的路径。在分析过程中发现,Dijkstra 算法在智能停车的路径规划中存在规划路径迂回、耗时过长等缺点。虽然基于 Dijkstra 算法的传统 A* 算法大大缩短了规划时间,但路径规划效果仍不理想。在四种算法中,BFS(广度优先搜索)算法的规划时间最短,但其规划的路径不稳定,不是最优路径。动态加权 A* 算法能取得较好的路径规划效果,而且通过调整权重值,该算法具有很好的适应性。本综述为进一步研究智能停车过程中的路径规划算法提供了参考。

As one of the fundamental vehicular perception technologies, millimeter-wave radar’s accuracy in angle measurement affects the decision-making and control of vehicles. In order to enhance the accuracy and efficiency of the Direction of Arrival (DoA) estimation of radar systems, a super-resolution angle measurement strategy based on the Fast Deterministic Maximum Likelihood (FDML) algorithm is proposed in this paper. This strategy sequentially uses Digital Beamforming (DBF) and Deterministic Maximum Likelihood (DML) in the Field of View (FoV) to perform a rough search and precise search, respectively. In a simulation with a signal-to-noise ratio of 20 dB, FDML can accurately determine the target angle in just 16.8 ms, with a positioning error of less than 0.7010. DBF, the Iterative Adaptive Approach (IAA), DML, Fast Iterative Adaptive Approach (FIAA), and FDML are subjected to simulation with two targets, and their performance is compared in this paper. The results demonstrate that under the same angular resolution, FDML reduces computation time by 99.30% and angle measurement error by 87.17% compared with the angular measurement results of two targets. The FDML algorithm significantly improves computational efficiency while ensuring measurement performance. It provides more reliable technical support for autonomous vehicles and lays a solid foundation for the advancement of autonomous driving technology.

This study presents a thermoset moulding compound designed for electrical machines with high power densities. The compound reduces residual stresses induced by the difference in thermal expansion during use and by shrinkage in the compound during the manufacturing process. To reduce the internal stresses in the compound, in the electrical sheet lamination and at their interface, first the moulding’s coefficient of thermal expansion (CTE) must match that of the lamination because the CTE of the electrical sheets cannot be altered. Second, the shrinkage of the compound needs to be minimized because the moulding compound is injected around a prefabricated electrical sheet lamination. This provides greater freedom in the design of an electric motor or generator, especially if the thermoset needs to be directly bonded to the electrical sheet. The basic suitability of the material for the injection moulding process was iteratively optimised and confirmed by spiral flow tests. Due to the reduction of the residual stresses, the compound enables efficient cooling solutions for electrical machines with high power densities. This innovative compound can have a significant impact on electric propulsion systems across industries that use laminated electrical sheets.
本研究介绍了一种专为高功率密度电机设计的热固性模塑料。该化合物可减少使用过程中的热膨胀差和制造过程中化合物收缩引起的残余应力。要降低化合物、电气板层压材料及其界面的内应力,首先模塑件的热膨胀系数(CTE)必须与层压材料的热膨胀系数相匹配,因为电气板的热膨胀系数无法改变。其次,由于模塑化合物是围绕预制电气板层压板注入的,因此需要尽量减少化合物的收缩。这为电机或发电机的设计提供了更大的自由度,尤其是当热固性材料需要直接粘合到电气板时。材料对注塑工艺的基本适用性经过反复优化,并通过螺旋流动测试得到确认。由于减少了残余应力,该化合物能够为高功率密度的电机提供高效的冷却解决方案。这种创新化合物可对使用层压电气板的各行业的电力推进系统产生重大影响。

Study of an Electric Vehicle Charging Strategy Considering Split-Phase Voltage Quality 考虑分相电压质量的电动汽车充电策略研究

Slow-charging electric vehicle (EV) loads are single-phase loads in the power distribution network (PDN). The random access of these EVs to the network brings to the forefront the split-phase voltage quality issues. Therefore, a two-layer EV charging strategy considering split-phase voltage quality is proposed in this paper. Issues with voltage unbalance (VU), split-phase voltage deviation (VD), and split-phase voltage harmonics (VHs) are included in the optimization objective model. An upgraded version of the multi-objective non-dominated sorting genetic algorithm (NSGA-II) is used in the inner layer of the model and to pass the generated EV phase selection scheme to the outer layer. The outer layer consists of a split-phase harmonic current algorithm based on the forward–backward generation method, and feeds the voltage quality calculation results to the inner layer. After several iterations, the optimal EV phase selection scheme can be obtained when the inner layer algorithm satisfies the convergence condition. The results gained for the example indicate that the suggested EV charging approach can effectively handle the PDN’s split-phase voltage quality. Furthermore, it enhances the energy efficiency of PDN operations and promotes further energy consumption.
缓慢充电的电动汽车(EV)负载是配电网络(PDN)中的单相负载。这些电动汽车随机接入配电网,使分相电压质量问题凸显出来。因此,本文提出了一种考虑分相电压质量的双层电动汽车充电策略。电压不平衡(VU)、分相电压偏差(VD)和分相电压谐波(VHs)等问题被纳入优化目标模型。模型内层使用了升级版的多目标非支配排序遗传算法(NSGA-II),并将生成的电动汽车相位选择方案传递给外层。外层由基于前向后生成法的分相谐波电流算法组成,并将电压质量计算结果反馈给内层。经过多次迭代,当内层算法满足收敛条件时,就能得到最优的电动汽车相位选择方案。示例结果表明,建议的电动汽车充电方法能有效处理 PDN 的分相电压质量问题。此外,它还提高了 PDN 运行的能效,促进了能源的进一步消耗。

The random access of these EVs to the network brings to the forefront the split-phase voltage quality issues. Therefore, a two-layer EV charging strategy considering split-phase voltage quality is proposed in this paper. Issues with voltage unbalance (VU), split-phase voltage deviation (VD), and split-phase voltage harmonics (VHs) are included in the optimization objective model. An upgraded version of the multi-objective non-dominated sorting genetic algorithm (NSGA-II) is used in the inner layer of the model and to pass the generated EV phase selection scheme to the outer layer. The outer layer consists of a split-phase harmonic current algorithm based on the forward–backward generation method, and feeds the voltage quality calculation results to the inner layer. After several iterations, the optimal EV phase selection scheme can be obtained when the inner layer algorithm satisfies the convergence condition. The results gained for the example indicate that the suggested EV charging approach can effectively handle the PDN’s split-phase voltage quality. Furthermore, it enhances the energy efficiency of PDN operations and promotes further energy consumption.","PeriodicalId":38979,"journal":{"name":"World Electric Vehicle Journal","volume":null,"pages":null},"PeriodicalIF":2.6,"publicationDate":"2024-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141825152","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The estimation of energy consumption under real-world driving conditions is a prerequisite for optimizing bus scheduling and meeting the requirements of route operation, thereby promoting the large-scale application of battery electric buses. However, the limitation of data accuracy and the uncertainty of many factors, such as weather conditions, traffic conditions, and driving styles, etc. make accurate energy consumption estimation complicated. In response to these challenges, a new method for estimating the energy consumption of battery electric buses (BEBs) is proposed in this research. This method estimates the speed profiles of different driving styles and the energy consumption extremes using real-world driving data. First, this research provides the constraints on speed formed by environmental factors including weather conditions, route characteristics, and traffic characteristics. On this basis, there are two levels of estimation for energy consumption. The first level classifies different driving styles and constructs the corresponding speed profiles with the time interval (10 s), the same as real-world driving data. The second level further constructs the speed profiles with the time interval of 1 s by filling in the first-level speed profiles and estimating the energy consumption extremes. Finally, the estimated maximum and minimum value of energy consumption were compared with the true value and the results showed that the real energy consumption did not exceed the extremes we estimated, which proves the method we proposed is reasonable and useful. Therefore, this research can provide a theoretical foundation for the deployment of battery electric buses.
实际驾驶条件下的能耗估算是优化公交调度、满足线路运营要求的前提,从而促进电池电动公交车的大规模应用。然而,由于数据精度的限制以及天气条件、交通状况、驾驶方式等诸多因素的不确定性,使得精确的能耗估算变得复杂。针对这些挑战,本研究提出了一种估算电池电动公交车(BEB)能耗的新方法。该方法利用实际驾驶数据估算不同驾驶方式的速度曲线和能耗极值。首先,本研究提供了由天气条件、路线特征和交通特征等环境因素对速度形成的限制。在此基础上,对能耗的估算分为两个层次。第一级对不同的驾驶风格进行分类,并以与实际驾驶数据相同的时间间隔(10 秒)构建相应的速度曲线。第二级通过填充第一级速度曲线并估算能耗极值,进一步构建时间间隔为 1 秒的速度曲线。最后,将估计出的能耗最大值和最小值与真实值进行比较,结果表明真实能耗并未超过我们估计的极值,这证明我们提出的方法是合理和有用的。因此,这项研究可以为电池电动公交车的部署提供理论基础。

The advancement of new energy vehicles (NEVs) represents a strategic initiative to combatting climate change, mitigating the energy crisis, and fostering green growth. Using provincial panel data from China between 2017 and 2022, in this study, we applied machine learning techniques for sentiment analysis of textual reviews, used word frequency statistics to explore consumers’ views on the attributes of new energy vehicles, and constructed a consumer sentiment index to study the impact of consumer sentiment on NEV sales. Considering the dependence of NEVs on a charging station, this paper explores the nonlinear impact of the popularity of charging stations on the relationship between consumer sentiment and sales of new energy vehicles. The findings indicate the potential for enhancement in the areas of space, interior design, and comfort of NEVs. Additionally, consumer sentiment was found to facilitate the diffusion of NEVs, with this effect being heterogeneous across different educational backgrounds, income levels, and ages. Furthermore, the availability of per capita public charging stations was shown to significantly reduce range anxiety and encourage consumer purchasing behavior.

This research presents a novel current loop control strategy for a three-phase PWM rectifier system aimed at mitigating challenges related to substandard power quality, excessive current harmonics, and insufficient robustness. The suggested approach combines an extended state observer (ESO) with dual-power sliding mode control that is further enhanced by fractional-order micro-integral operators. This amalgamation enhances the adaptability of the controller to system dynamics and augments the flexibility of the current loop control mechanism. The results of this integration include diminished system oscillations, heightened immunity to external disturbances, and improved robustness and dynamics of the overall system. Through MATLAB/Simulink simulations, the effectiveness of the proposed control methodology is validated, demonstrating superior performance in terms of robustness, dynamic response, power quality enhancement, and mitigation of current harmonics when compared to conventional PI control and standard fractional-order dual-power sliding mode control techniques.
