Most comparison studies of MPPT algorithms in the literature are undertaken in terms of their precision, speed, robustness under rapidly changing environmental conditions, etc... In grid-connected photovoltaic (PV) systems, Comparative studies of MPPT methods in terms of THD injected into the network are of significant importance. In this paper, two conventional MPPT methods, perturb and observation (P&O) and incremental conductance (IC), and two advanced MPPT methods, fuzzy logic control (FLC) and Sliding mode control (SMC), were studied and compared in terms of currents injected THD into the grid using MATLAB/Simulink. The grid-connected PV system under consideration is a two-stage unit that includes a classical boost converter and a two-level voltage source inverter. With the FLC and SMC-based MPPT methods, the injected current's THD was 1.34% and 1.99%, respectively. The IC MPPT technique has slightly outperformed the P&O one, with a THD current of 3.48% versus 3.68%. The simulations were run under identical conditions; the superior performance of a particular MPPT technique over others is principally reflected in the dc-link voltage fluctuation.
文献中大多数MPPT算法的比较研究都是在其精度、速度、快速变化环境条件下的鲁棒性等方面进行的。在光伏并网系统中,比较研究MPPT方法对电网注入THD的影响具有重要意义。本文利用MATLAB/Simulink,研究了扰动观测法(P&O)和增量电导法(IC)这两种传统的MPPT方法,以及模糊逻辑控制法(FLC)和滑模控制法(SMC)这两种先进的MPPT方法,并对THD注入电网的电流进行了比较。考虑中的并网光伏系统是一个两级单元,包括一个经典升压变换器和一个两电平电压源逆变器。基于FLC和smc的MPPT方法,注入电流的THD分别为1.34%和1.99%。IC MPPT技术的THD电流为3.48%,略优于P&O技术的3.68%。模拟在相同条件下进行;一种特定的MPPT技术优于其他技术的性能主要体现在直流链路电压波动上。

Intelligent Reflecting Surfaces (IRS) are constructed of multiple independently controllable passive Reflecting Elements (RE), which can change the phase and amplitude of the reflected signals so that the reflected signals can be combined in coherent manner to achieve beamforming. To facilitate beamforming, the channel coefficients of the incoming and outgoing channels need to be estimated. In this study, the Discrete Fourier Transform (DFT) based channel estimation method is applied to an IRS-assisted communication system implementing Fifth Generation (5G) Orthogonal Frequency Division Multiplexing (OFDM) waveform in order to observe the effectiveness of the estimation method. DFT-based channel estimation has the advantage of not using the whole OFDM symbol for pilot transmission, thus it can be performed while transmitting data. Therefore, the effects of multipath delay spread, the number of REs, and training sequence sparsity in the OFDM symbol are observed for different Signal-to-Noise Ratio (SNR) values with a direct path and without a direct path. The results show that delay spread has a significant effect on the performance and training sequence length can be reduced.
智能反射面(IRS)由多个独立可控的被动反射元件(RE)组成,通过改变反射信号的相位和幅度,使反射信号进行相干组合,实现波束形成。为了方便波束形成,需要估计输入和输出信道的信道系数。本研究将基于离散傅立叶变换(DFT)的信道估计方法应用于实现第五代(5G)正交频分复用(OFDM)波形的irs辅助通信系统,以观察该估计方法的有效性。基于dft的信道估计具有不使用整个OFDM符号进行导频传输的优点,因此可以在传输数据时进行信道估计。因此,在有直接路径和没有直接路径的不同信噪比(SNR)值下,观察了OFDM符号中多径延迟扩展、REs数和训练序列稀疏度的影响。结果表明,延迟扩展对性能有显著影响,可以减少训练序列长度。

Due to the penetration of different renewable energy sources and DC storage systems, DC microgrids (MGs) have been studied extensively. The optimal planning of DC microgrids directly impacts the operation and control algorithms; thus, coordination among them is required. The safe operation of DC microgrids has been ensured by different control techniques, such as centralized, decentralized, distributed and hierarchical control. This paper studies a DC-MG planning model. A time series and feedforward nonlinear autoregressive neural network (NARX) have been used for forecasting the load demand and level of solar Irradiance. Furthermore, the total operating cost has been minimized via optimization of the unit commitment problem while including the dynamic pricing of grid power. The system performance have been evaluated using MATLAB.

The increasing demand for the interconnected IoT based smart grid is facing threats from cyber-attacks due to inherent vulnerability in the smart grid network. There is a pressing need to evaluate and model these vulnerabilities in the network to avoid cascading failures in power systems. In this paper, we propose and evaluate a vulnerability assessment framework based on attack probability for the protection and security of a smart grid. Several factors were taken into consideration such as the probability of attack, propagation of attack from a parent node to child nodes, effectiveness of basic metering system, Kalman estimation and Advanced Metering Infrastructure (AMI). The IEEE-300 bus smart grid was simulated using MATPOWER to study the effectiveness of the proposed framework by injecting false data injection attacks (FDIA); and studying their propagation. Our results show that the use of severity assessment standards such as Common Vulnerability Scoring System (CVSS), AMI measurements and Kalman estimates were very effective for evaluating the vulnerability assessment of smart grid in the presence of FDIA attack scenarios.

Modular wireless power distribution systems will be commonly used in next generation factories to supply industrial production equipment, in particular automated guided vehicles. This requires the development of a flexible and standardized communication system in between individual Wireless Power Transfer (WPT) modules and production equipment. Therefore, we first derive the requirements for such a system in order to incorporate them in a generic communication concept. This concept focuses on the zero configuration and user-friendly expandability of the system, in which the communication unit is integrated in each WPT module. The paper describes the communication concept and discusses the advantages and disadvantages. The work concludes with an outlook on the practical implementation in a research project.

The main function of Protective equipment is the provision of adequate level of network reliability and stability. In the electric system, directional overcurrent relays (DOCRs) are widely incorporated. The primary and decisive goal of DOCRs is to keep healthy sections in operation and disconnect only the fault part rapidly. This problem contains many boundaries, in which different single-objective algorithms are suggested. The relay settings are defined as the decision variables for this optimization problem. A grey wolf optimizer (GWO), an enhanced version of grey wolf optimizer (EGWO), a whale optimization algorithm, and hybrid whale-grey wolf optimizer (HWGO), Equilibrium Optimizer (EO), and Flow Direction Algorithm (FDA) are used to solve coordination problems as a single objective function. The effectiveness and feasibility of the suggested techniques are evaluated using different networks Also, they are compared with other methods.

Concerns about long-term sustainability and stability have led to an unprecedented shift in electric power systems toward the rapid integration of renewable generation. This integration is achieved via application of power electronic converters, leading to low inertia networks. A system with low inertia is deficient in maintaining system stability. In this context, voltage source converters with grid-forming control are proposed to provide inertia to the network which was previously provided by synchronous machines. However, the majority of grid forming control analysis ignores the DC side dynamics and transmission line parameters. In this paper, three grid forming control techniques with DC side dynamics are explored, and their interaction with the synchronous machine in low inertia test cases are presented. The test results are validated using MATLAB/Simulink simulation of a modified IEEE 9-bus system.

Nowadays, the modeling of the photovoltaic model becomes more and more important because it allows the industry to understand more about its electrical circuit, which leads to better reliability. This electrical circuit can have five, seven, or nine parameters depending on the number of diodes. This paper discusses a novel method to extract the seven parameters of a double diode (DD) model based on datasheet parameters. The present approach combines genetic algorithms (GA) and analytical methods: Two parameters (photo-generated current and parallel resistance) are computed analytically, while the other parameters are optimized using the GA. The objective function used contains open circuit, short-circuit, and maximum power equations. The extracted seven parameters generated with this method are compared to those obtained through other methods. To assess the efficacy and reliability of the proposed approach, the P-V and I-V properties are evaluated using datasheet at various temperatures and solar irradiations.

如今,光伏模型的建模变得越来越重要,因为它可以让业界更多地了解其电路,从而提高可靠性。根据二极管的数量,该电路可以有5个、7个或9个参数。本文讨论了一种基于数据表参数提取双二极管(DD)模型七个参数的新方法。该方法将遗传算法(GA)与解析方法相结合,对光产生电流和并联电阻两个参数进行解析计算,并利用遗传算法对其他参数进行优化。所使用的目标函数包含开路、短路和最大功率方程。并将该方法提取的7个参数与其他方法的参数进行了比较。为了评估所提出方法的有效性和可靠性,使用数据表在不同温度和太阳辐照下评估P-V和I-V特性。结果显示出很强的相关性;计算了电流的均方根误差(RMSE)和绝对误差,验证了模型的性能。

This electrical circuit can have five, seven, or nine parameters depending on the number of diodes. This paper discusses a novel method to extract the seven parameters of a double diode (DD) model based on datasheet parameters. The present approach combines genetic algorithms (GA) and analytical methods: Two parameters (photo-generated current and parallel resistance) are computed analytically, while the other parameters are optimized using the GA. The objective function used contains open circuit, short-circuit, and maximum power equations. The extracted seven parameters generated with this method are compared to those obtained through other methods. To assess the efficacy and reliability of the proposed approach, the P-V and I-V properties are evaluated using datasheet at various temperatures and solar irradiations. The results demonstrate a strong correlation; moreover, the Root Mean Square (RMSE) and the absolute error of current have been computed, and the model’s performance has been confirmed.","PeriodicalId":441321,"journal":{"name":"2022 4th Global Power, Energy and Communication Conference (GPECOM)","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133439345","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}

This paper presents a performance evaluation of a selected group of current sensors available in the market. The sensors were tested from 60 mA to 2 A current values in a 9-W, 60-kHz, multiport boost converter from a Battery Management System which is controlled by a 32-bits microcontroller. The evaluation reported in this work presents the current waveforms obtained from a current probe and compared against the output signal of each sensor under study. Advantages and features of each sensor are detailed as well as their prices. Finally, two sensors with outstanding performance are implemented in a closed-loop control scheme in a single boost converter offering a good insight of the quality-price balance.
