Power supplies used by most present power conversions including motor drive systems produce non-sinusoidal current. Unwanted harmonics in non-sinusoidal currents wreak havoc on a grid's supply chain. Other equipment that relies on the same power source is negatively impacted. An AC-DC converter that permits bi-directional power flow, improves input power factor, and minimises chromatic frequency and perturbation in the system's power supply is the subject of this study. The converters' total efficiency is improved because to the bi-directional function, which enables them to collect regenerative energy from loads and feed it back into the power supply. Electric operated robots, elevators, and other large-scale industrial driving systems might all benefit greatly from this converter. © 2023 IEEE.

this article affords an outline of the effectiveness of multi-thing authentication (MFA) for stopping cyber attacks. MFA is an authentication procedure that combines or greater elements or traits to verify the identification of a character or user earlier than granting them access. This sort of authentication is increasingly being used to protect non-public data and to prevent unauthorized get admission to systems and services. Diverse studies have been carried out to evaluate the effectiveness of MFA as compared to traditional authentication methods, like passwords. The outcomes of these studies show that after properly implemented, MFA may be a powerful method to shield towards cyber-assaults. This article also presents satisfactory practices for implementing MFA to maximize its effectiveness and discusses risks related to using MFA. © 2024 IEEE.

This paper presents the two configurations of partial power processing converter for onboard electric vehicles (EVs) charging using the traditional full power processing dual active bridge DC-DC converter. The two configurations are Input Parallel and Output Series (IPOS) Series Output Parallel (ISOP) partial power converters for high- and low-voltage battery charging applications. IPOS and ISOP can bidirectional power transfer from source to battery and vice-versa through the direct and partial paths. The partial path only comprises passive and magnetic components, whereas no components are on the direct path. To validate the performance of the proposed configurations of partial power processing, converters have been simulated and tested using MATLAB / Simulink toolbox, and their results are compared with the full-power processing dual active bridge converter under the various loaded conditions. The results show that the IPOS and ISOP configurations provide an efficiency of about 94% under full load conditions, i.e., during battery charging and observed to be 4-6% higher than the full power converter configuration. Also, IPOS and ISOP schemes handle less than 50% of output power via the partial paths. Therefore, power ratings and sizes of the semiconductor and passive devices can be significantly reduced compared to the full power converter. Hence, it is observed that these two configurations are best suited for onboard EV chargers. © 2023 IEEE.

Cell-free massive multiple input multiple output (MaMIMO) is perceived as a capable solution for the induced inter-cell interference, and fair quality of service distribution among users in sixth generation (6G) networks. As well, non-terrestrial networks, and specifically unmanned aerial vehicle (UAV) communications, are viewed for an integrated air-ground networks that will provide the needed coverage for rural areas and recovery services. Yet, the strong line of sight affects of the UAV links produces a challenging integration, which can be averted by exploiting cell-free structure. Hence, it is the aim of this study to describe existing literature on UAV based cell-free MaMIMO networks. The presented study will accentuate UAV use cases and 6G new technologies that will further support this integration. Future research directions and gaps are also identified. © 2023 IEEE.

In a ring configuration microgrid, due to the inherent characteristics of distributed energy sources, the bidirectional power flow dominates the unidirectional flow which will not empower the conventional current-based protection techniques. Moreover, traditional methods fail to identify exact faulty line during high resistance faults. The aim of the work is to propose an effective protection algorithm that emphasizes the enhancement of dependability of the relay even during fault condition with high magnitude resistance. To start with, the current difference index has been evaluated to detect the disturbance or fault in the system. In continuation, the resistance has been computed by utilizing voltage and current sampled data immediately after inception of the fault. Further, the sign of R is employed to differentiate the internal and external faults correctly. The proposed algorithm has been simulated under many abnormal cases like different fault resistances at multiple fault locations and different load switching conditions in MATLAB/Simulink software. The comparative assessment of this proposed method has been done with existing protection methods justifying that proposed method is reliable and enhances relay dependability and security. © 2023 IEEE.

In this paper, we propose a novel design principle for fixed-beam leaky wave antenna. Inserting the phase loading structures between the radiation units, one can achieve a high gain in the direction of the endfire. Supported by the characteristic of the leaky wave antenna, the scanning rate can be slowed down near the endfire direction. By designing the parameters according to the theoretical formula, one can split the endfire beam into two fixed beams in the desired band. Simulated results show that the proposed fixed-beam antenna achieves 13.2 dBi and 8-degree angle deviation in the band between 16-17 GHz. © 2023 IEEE.

Deregulated power supply is taken over power distribution to regulate the electricity demand worldwide. In the context of a deregulated setting, accurately determining the Available Transfer Capability (ATC) within a transmission system emerges as a significant challenge. The evaluation of ATC is restricted by the stability constraints inherent in the system. Estimation of ATC with dynamic stability limit is indicated as dynamic ATC (DATC). In this work, the transient stability limit, incorporated with dynamic instability is an aforethought constraint to compute DATC. Transmission Stability Index (TSI) is calculated to identify the most contingency line. Reckoning of Transient stability constrained DATC (TSDATC) is attained by Iterative Transient Stability Approach (ITSA). The outlined method is utilized to estimate Dynamic ATC for multilateral transactions. This method has been put in to practice and evaluated in New England 10 machine 39-bus system. Subsequently, the approach was expanded to encompass a deregulated power network integrated with a wind generator employing variable-speed technology, centered around a Doubly Fed Induction Generator (DFIG). The test results have demonstrated that the TSDATC is lower in comparison to scenarios where wind generators are not present. These findings indicate that wind power operations become increasingly vulnerable to TSDATC, rendering the system less robust in the presence of fault conditions. © 2023 IEEE.

Addressing power quality issues in distribution systems is of utmost importance for both consumers and suppliers. By effectively mitigating these issues, benefits such as increased efficiency, cost reduction, uninterrupted power supply, and minimized maintenance needs can be realized. Custom power devices have emerged as viable solutions to tackle challenges like voltage fluctuations, transients, imbalances, and harmonic distortions in distribution systems. Among these devices, the Unified Power Quality Conditioner (UPQC) and the Photovoltaic Unified Power Quality Conditioner (PV-UPQC) stand out for their remarkable ability to improve power quality in distribution systems. Over the years, researchers have proposed various structural configurations of UPQC and PV-UPQC to enhance their performance. This study aims to comprehensively review the existing literature on UPQC and PV-UPQC models and evaluate how different structural setups impact the devices' performance and overall distribution system quality. Furthermore, the investigation delves into the characteristics, applications, and control strategies employed by these UPQC and PV-UPQC configurations to effectively alleviate power quality issues. By gaining insights from this extensive review, a more profound comprehension of the strategies for augmenting power quality in distribution systems can be achieved. © 2023 IEEE.

This paper develops a robust non-linear control system that employs the sliding mode control (SMC) technique to enhance the speed regulation performance of the permanent-magnet-synchronous-motor (PMSM) in the existence of parameter mismatch and external load disturbances. Initially, the modified reaching law-based SMC (MRL-SMC) method is proposed. This MRL-SMC incorporates an exponential sliding surface function and system tracking error to enable adaptive changes in the reaching law during two distinct SMC phases. As a result, this method mitigates the inherent chattering generated in the control input and accelerates the reaching speed of the system states towards the sliding manifold. Moreover, due to high switching gain requirement to suppress the effect of lumped disturbances give rise to large chattering. Therefore, an antidisturbance approach is proposed in composite to MRL-SMC. This method consists of a finite-time disturbance observer for estimating the lumped disturbance and initiate a feedforward compensation of the estimated disturbance to the MRL-SMC. Additionally, the simulation results demonstrate that the proposed speed control technique is more effective compared to conventional SMC. © 2023 IEEE.
