. The application of Electric Vehicles (EVs) is increasing in many countries, causing many researchers to focus on EV Rapid Charging Station (RCS) related issues. The optimal planning of RCS considering only distribution networks is not a reli-able approach. Moreover, the RCS location should be convenient to the EV user in a given EV driving range and the performance of the distribution system. In this paper, a multi-objective approach for optimal planning of RCS and Distributed Generators (DG) in a distributed system coupled with a transportation network is analyzed. The proposed optimal planning method aims to achieve reduced active power loss, EV user costs, and voltage deviation for effective RCS and DG planning. The approach includes the analysis of the test system with the base case, solo planning of RCS, planning of DGs with fixed RCS, and simultaneous optimal planning of RCS and DGs. Daily load variation at buses and hourly charging probability of EVs have been used in the analysis. IEEE 33 bus distribution system superimposed with a 25-node transportation network is considered the test system. Rao 3 algorithm is applied for optimization, and the results have been compared with PSO and JAYA algorithms.
电动汽车(EV)在许多国家的应用正在增加,这导致许多研究人员关注电动汽车快速充电站(RCS)的相关问题。仅考虑配电网的RCS优化规划是不可行的。此外,在给定的电动汽车行驶里程和配电系统的性能下,RCS的位置应该方便电动汽车用户。本文分析了与运输网络耦合的分布式系统中RCS和分布式发电机(DG)的多目标优化规划方法。所提出的优化规划方法旨在实现有效RCS和DG规划的有功功率损耗、电动汽车用户成本和电压偏差的降低。该方法包括带基本情况的测试系统分析、RCS的单独规划、固定RCS的DG规划以及RCS和DG的同时优化规划。分析中使用了公交车的日负荷变化和电动汽车的小时充电概率。IEEE 33总线配电系统与25节点的交通网络叠加被认为是测试系统。将Rao-3算法应用于优化,并与PSO算法和JAYA算法进行了比较。

. This work presents the quadrature sinusoidal oscillator using two Voltage Differencing-Differential Input Buffered Amplifiers (VD-DIBAs), two resistors, and two capacitors. The VD-DIBA is an electronically controllable active building block with high input and low output impedances that can con-nect to other circuits directly without the buffers. With these distinguished features, the VD-DIBA is employed in this design. The proposed oscillator can produce two sine waves with a phase shift of 90 degrees. Over the entire tuning frequency range, the magnitude of the quadrature output voltages is constant. The proposed oscillator is independently adjustable in terms of frequency and oscillation condition. Moreover, the frequency of oscillation can be electronically and linearly adjusted by the bias currents. The condition of oscillation is adjustable by resistors, R 1 and R 2 . The performances of the proposed quadrature oscillator are tested through the PSpice simulation and the experiment. In the simulation, the VD-DIBA is built from the 0.18 µ m Taiwan Semiconductor Manufactur-ing Company (TSMC) CMOS process with ± 0 . 9 V supply voltages. In the experiment, the VD-DIBA is implemented using the commercial ICs, LM13700, and AD830 with ± 5 V supply voltages. The simulated To-tal Harmonic Distortion (THD) values of the output voltages, V o 1 and V o 2 at f 0 = 1 . 03 MHz are 1.63 % and 1.81 % , respectively. The experimental THD values of the output voltages, V o 1 and V o 2 at f 0 = 536 . 6 kHz, are 1.43 % and 1.00 % , respectively.

. Improving the behavior of speed control in electric vehicles is currently a major challenge for re-searchers and engineers. For this study, we chose the context of a Switched Reluctance Motor (6/4 SRM) used in a hybrid Electric Vehicle with Extended Range (EREV). Speed regulation is an essential feature on long-distance trip. Speed regulators of backstepping type are very effective in this context given the nonlinear nature of switched reluctance motors. The estimation of non-linear quantities, flux and inductance, uses Legendre polynomials. The control strategy uses four regulators, one for speed and three for stator currents. It is based on the Torque Sharing Function (TSF) and the Torque Inverse Model (TIM). Our simulation consists of studying the behavior of this type of control when an Inter-Turn Short-Circuit (ITSC) fault appears on one of the phases of the 6/4 SRM. In this paper, we are interested in temporal behavior of phasic currents and we will show the interest of these quantities as fault indicators allowing the real time diagnosis of this type of controller-machine.

. This paper proposes a novel linear precoding method for Orthogonal Frequency Division Multiplexing (OFDM) based on the employment of the chaotic waveforms generated by the fourth-order chaotic oscillator and orthonormalized by the Gram-Schmidt process. The proposed linear precoding method is aimed to increase resilience to the multipath propagation issues and reduce the Peak-to-Average Power Ratio (PAPR) of the transmitted signal. Moreover, the chaotic waveform enables novel timing synchronization methods to be implemented in the receiver. The modeling of baseband Linear Precoded OFDM (LP-OFDM) data transmission system with Rayleigh channel has been performed in Simulink en-vironment to validate the proposed method and to compare the performance to the classic precoding methods, such as Walsh-Hadamard Transform (WHT). Experiments have shown that in a high Signal-to-Noise Ratio (SNR) scenario, the employment of the novel precoding scheme allows reducing Bit Error Ratio (BER) by several dB compared to non-precoded OFDM. The proposed precoding method leads to the reduction of PAPR; however, it is not as efficient as classical precoding schemes, such as WHT. Experimental evidence of synchronization of the chaotic oscillators within 50 samples long time interval is presented.
。本文提出了一种新的正交频分复用(OFDM)线性预编码方法,该方法利用四阶混沌振荡器产生的经Gram-Schmidt过程正交标准化的混沌波形。提出的线性预编码方法旨在提高对多径传播问题的弹性,降低传输信号的峰均功率比(PAPR)。此外,混沌波形使得在接收机中实现新的定时同步方法成为可能。在Simulink环境下对基于瑞利信道的基带线性预编码OFDM (lc -OFDM)数据传输系统进行了建模,验证了所提方法的有效性,并与经典预编码方法(如Walsh-Hadamard Transform, WHT)的性能进行了比较。实验表明,在高信噪比(SNR)的情况下,与非预编码OFDM相比,采用新的预编码方案可以将误码率(BER)降低几个dB。所提出的预编码方法降低了PAPR;然而,它的效率不如经典的预编码方案,如WHT。给出了混沌振荡器在50个样本长时间间隔内同步的实验证据。

. From the beginnings of ITU-T H.261 to H.265 (HEVC), each new video coding standard has aimed at halving the bitrate at the same perceptual quality by redundancy and irrelevancy reduction. Each improvement has been explained by comparably small changes in the video coding toolset. This contribu-tion aims at starting the Quality of Experience (QoE) analysis of the accumulated improvements over the last thirty years. Based on an overview of the changes in the coding tools, we analyze the changes in the quantized residual information. Visual comparison and statistical measures are performed and some interpreta-tions are provided towards explaining how irrelevancy reduction may have led to such a huge reduction in bitrate. The interpretation of the results in terms of QoE paves the way towards an understanding of the coding tools in terms of visual quality. It may help in understanding how the irrelevancy reduction has been improved over the decades. the differences of the residuals relate to known or yet un-known properties of the human visual system, may en-able a closer collaboration between perception research and video compression research.
从ITU-T H.261开始到H.265(HEVC),每一个新的视频编码标准都旨在通过冗余和无关性减少来在相同感知质量下将比特率减半。视频编码工具集中相对较小的变化解释了每一项改进。该贡献旨在开始对过去三十年中积累的改进进行体验质量(QoE)分析。基于对编码工具变化的概述,我们分析了量化残差信息的变化。进行了视觉比较和统计测量,并提供了一些解释来解释不相关的减少是如何导致比特率如此巨大的降低的。根据QoE对结果的解释为理解视觉质量方面的编码工具铺平了道路。这可能有助于理解几十年来无关紧要的减少是如何得到改善的。残差的差异与人类视觉系统的已知或未知特性有关,可能能够在感知研究和视频压缩研究之间进行更紧密的合作。

Fault Detection and Classification in Interconnected System with Wind Generation Using ANN and SVM 基于神经网络和支持向量机的风力发电互联系统故障检测与分类

. Protective relays are installed in generation, transmission, and distribution system for detection, classi(cid:28)cation, and estimation of faults. To match the future load demand and to get uninterrupted power supply, use of renewable energy sources are increasing day by day. Faults can occur in transmission lines, transformers, generators, and busbars but the nature of these faults may change many times when renewable energy sources are considered. This research paper introduce techniques to detect and classify different faults on transmission line in the presence of wind energy sources using ef(cid:28)cient tools of ar-ti(cid:28)cial intelligence. The main challenges of the system fault detection, in presence of wind turbine lie in their non-linearity, uncertainty and unknown disturbances. PSCAD/EMTDC software tool is used to sim-ulate the power system model with RES which is implemented in MATLAB and Python software. Arti(cid:28)cial Neural Network (ANN) and Support Vector Machine (SVM) algorithms have been used to classify and detect faults on transmission lines connected with wind energy source. The proposed technique has been validated for internal faults on transmission line and external faults on power system. In total of 4320 internal and external fault cases with wide variation in system parameters have been used for validation of the proposed model. The proposed model gives an overall fault zone identi(cid:28)cation accuracy of more than 99 % in presence of wind energy source. The results obtained from validation show that the performance of SVM classi(cid:28)er is better than ANN in term of ef(cid:28)cacy and classi(cid:28)cation time.
保护继电器安装在发电、输电和配电系统中,用于检测、分类(cid:28)和估计故障。为了满足未来的负荷需求并获得不间断的电力供应,可再生能源的使用日益增加。输电线路、变压器、发电机和母线可能发生故障,但考虑可再生能源时,这些故障的性质可能会发生多次变化。本文介绍了在有风能的情况下,利用人工智能的有效工具对输电线路上的不同故障进行检测和分类的技术。在风机存在的情况下,系统故障检测的主要挑战在于其非线性、不确定性和未知扰动。利用PSCAD/EMTDC软件工具,利用MATLAB和Python软件实现的RES对电力系统模型进行仿真。Arti(cid:28)神经网络(ANN)和支持向量机(SVM)算法已被用于对与风能连接的输电线路上的故障进行分类和检测。该技术已在输电线路内部故障和电力系统外部故障中得到验证。总共使用了4320个系统参数变化较大的内部和外部故障案例来验证所提出的模型。所提出的模型在存在风能的情况下,给出了超过99%的整体断层带识别准确度(cid:28)。验证结果表明,SVM classi(cid:28)er在ef(cid:28)cacy和classi(acid:28)阳离子时间方面的性能优于ANN。

Protective relays are installed in generation, transmission, and distribution system for detection, classi(cid:28)cation, and estimation of faults. To match the future load demand and to get uninterrupted power supply, use of renewable energy sources are increasing day by day. Faults can occur in transmission lines, transformers, generators, and busbars but the nature of these faults may change many times when renewable energy sources are considered. This research paper introduce techniques to detect and classify different faults on transmission line in the presence of wind energy sources using ef(cid:28)cient tools of ar-ti(cid:28)cial intelligence. The main challenges of the system fault detection, in presence of wind turbine lie in their non-linearity, uncertainty and unknown disturbances. PSCAD/EMTDC software tool is used to sim-ulate the power system model with RES which is implemented in MATLAB and Python software. Arti(cid:28)cial Neural Network (ANN) and Support Vector Machine (SVM) algorithms have been used to classify and detect faults on transmission lines connected with wind energy source. The proposed technique has been validated for internal faults on transmission line and external faults on power system. In total of 4320 internal and external fault cases with wide variation in system parameters have been used for validation of the proposed model. The proposed model gives an overall fault zone identi(cid:28)cation accuracy of more than 99 % in presence of wind energy source. The results obtained from validation show that the performance of SVM classi(cid:28)er is better than ANN in term of ef(cid:28)cacy and classi(cid:28)cation time.","PeriodicalId":7268,"journal":{"name":"Advances in Electrical and Electronic Engineering","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2022-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48624663","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}

. Leading digital circuits namely register, flipflops, state machines and counters drive operational aspects and potential applications in Integrated Circuit (IC) industry. based implementations with rapid response and simul-taneous generation of complemented output is all set to become indispensable in nano regime industry. This paper attempts to optimize and address performance-based analysis of digital circuits namely NAND, D flipflop and 3-bit asynchronous counter by practicing MCML based implementation. These circuits are con-templated on four design parameters namely delay ( t p ), power (pwr), Power Delay Product (PDP) and Energy Delay Product (EDP). This research focuses on relative analysis and emanate a salient optimal application of Complementary Metal-Oxide-Semiconductor (CMOS) and Carbon Nanotube Field Effect Transistor (CNFET) based 3-bit asynchronous counter. In ad-dition to this, the two configurations of the MCML counter are then compared against applied V DD at 16-nm technology nodes using HSPICE simulator. CNFET based 3-bit MCML counter is observed to be much faster (9.75 × ), significant improvement in gross power dissipation (11.93 × ), material refinement in PDP and EDP (116.39 × and 1165 × ) re-spectively as compared to the conventional counterpart. Therefore, CNFET based implementations comes to the fore as resilient technology supporting high level integration in nano scale regime.
领先的数字电路,即寄存器、触发器、状态机和计数器,驱动集成电路(IC)行业的操作方面和潜在应用。具有快速响应和同时生成补充输出的基于实现将成为纳米体制工业中不可或缺的一部分。本文试图通过实践基于MCML的实现来优化和解决数字电路(即NAND、D触发器和3位异步计数器)的性能分析。这些电路以四个设计参数为模板,即延迟(tp)、功率(pwr)、功率延迟乘积(PDP)和能量延迟乘积(EDP)。本研究着重对互补金属氧化物半导体(CMOS)和碳纳米管场效应晶体管(CNFET)三位异步计数器进行了相关分析,并提出了一个显著的优化应用。除此之外,还使用HSPICE模拟器将MCML计数器的两种配置与16nm技术节点处应用的VDD进行比较。与传统计数器相比,基于CNFET的3位MCML计数器速度快得多(9.75倍),总功耗显著提高(11.93倍),PDP和EDP的材料细化(116.39倍和1165倍)。因此,基于CNFET的实现方式作为支持纳米级高水平集成的弹性技术而脱颖而出。
