This paper studied the design of a predictive current control strategy with fault tolerance and reactive power minimization applied to a multi-modular topology based on indirect 2-level matrix converters fed by a six-phase generator. The control algorithm of the proposed strategy involves coupled current signals to perform error compensation between the converter modules, aiming to address potential system faults while maintaining reactive power close to zero. The results, obtained through simulation, were evaluated considering each module’s input and output currents and the final load current, as well as reactive power minimization, incorporating the obtained values of total harmonic distortion and mean squared error. The behaviour was analyzed in steady-state and transient conditions, with the system operating nominally and under fault conditions. The results demonstrate the effectiveness and good performance of the proposed strategy with the utilized topology, achieving a satisfactory response to faults through compensation and constant reactive power minimization. © 2024 IEEE.

Network on Chip (NoC) is a communication subsystem between various IPs interconnected through an on-chip router inside a single chip. The on-chip interconnection infrastructure connects the different intellectual property (IP) with the help of various industry-standard high-performance (HPC) interconnection topologies. Also, the on-chip interconnection network facilitates the connection of more Processing Elements (PE) to enable deadlock-free scheduling and parallel processing. The present work addresses one important aspect of NoC which is "Optimal Mapping" which allows the participation of cores in an optimal way for achieving low bandwidth requirement, low latency hence greater throughput. To achieve the optical mapping, a Genetic Algorithm is proposed here for the optimization of NoC performance by employing 2D Mesh topology. The genetic algorithm produces consistent and comparable results at par with standard algorithms. A deterministic seeding and successive seeding would yield better results and consume less CPU time. The proposed result is marginally better than NMAP and PSMAP. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

Network programming is the act of writing computer codes for communications between programs or processes in different computers across networks. It is crucial for applications and services using networks, including e-commerce, gaming, and social media. However, university courses of educating it are very limited. As a result, it has become important to develop and offer IT tools to support self-studies of network programming by novices. In this paper, we present a study of two types of introductory exercise problems, namely, Grammar-concept Understanding Problem (GUP) and Comment Insertion Problem (CIP), for self-studies of five basic network protocols of TCP/IP, ARP, SMTP, POP3, and SSH with Python. A GUP instance requests to answer the keyword such as a library function in the given source code that corresponds to the grammar concept described in the question. A CIP instance requests to insert the comment at each blank of the code. String matching is adopted to mark any answer at the browser-based answer interface. Through solving them, it is expected to understand the meaning of important words and the code structure for network programming. As preliminary evaluations, we generated six GUP and CIP instances respectively, and assigned them to 10 students in Okayama University, Japan. The results confirmed that the proposal is proper for novices to learn network programming with Python. © 2023 ACM.

The substation is the core facility of the power system. The interaction and coordination of different equipment in the protection and monitoring system(PMS) directly affects the working efficiency and stable operation of the system. However, the current protection and monitoring system of substation(SPMS) generally lacks evaluation method for collaboration. To the above problems, this paper proposes an evaluation method for collaboration in S-PMS based on the G1 method. Firstly, according to the requirements of the coordination for PMS, the corresponding indicators are proposed to form the index system for evaluating the coordination. Then, combined with G1 method, a comprehensive collaboration evaluation model is constructed. Finally, the coordination of two different structures of substations is evaluated and analyzed, and the feasibility of the evaluation method is verified. © 2023 IEEE.

IEEE Transactions on Transportation Electrification 2025年

Variable phase-pole machines possess the capability to expand their operational range by employing magnetic pole change while adhering to the same electrical voltage and current limits. This paper proposes a strategy to achieve a pole change with constant torque while simultaneously optimizing current distributions for stator copper loss minimization. The overall outcome is the ability to facilitate smooth dq0 current transitions while reducing the energy consumption of variable phase-pole machine drives. Experimental results affirm the efficacy of this approach during the pole change process. © 2025 IEEE.

In this study, our focus lies on the issue of optimal load frequency control (LFC) in a multi-area interconnected power system. A shared control strategy that incorporates knowledge of human operational behavior is proposed. Given the difficulty in obtaining analytical models of operators, a Gaussian process regression is introduced to construct a data-driven model for operator behaviors. To improve the performance of the multi- area interconnected power system, a shared control approach with an operational model is presented, which integrates grid state information and operator instructions. Specifically, a GP-MPC is designed to predict the system states by propagating uncertainty and obtain an optimal control profile within the prediction horizon. Several experiments are conducted to validate the efficiency of the proposed shared control approach. © 2024 IEEE.

Rogowski coils are widely used for converting high-ampere currents in electrical installations. Large number of manufacturers produce Rogowski coils in various form factors. The use of this type of converters is promising for relay protection of electric power systems equipment due to such advantages as linearity of conversion, absence of saturation and residual magnetization phenomena, high accuracy of high-ampere current conversion. The metrological characteristics of the Rogowski coil depend on various factors that do not affect traditional current converters (electromagnetic transformers). One of these factors is the ambient temperature. The impact of ambient temperature can lead to an irreversible change in the size of coil turn and a corresponding change in the measurement error. In addition, commercially available Rogowski coils have a temperature coefficient of error of the conversion ratio from 0.005 to 0.02%/°C according to datasheets. Non-traditional current converters do not have sufficient experience in the conditions of electric power facilities operating in comparison with electromagnetic transformers. A comprehensive study of the characteristics of Rogowski coils is needed before their large-scale application for current measurement in electric power systems. This article is devoted to the study of the conversion errors of Rogowski coils in a wide temperature range corresponding to a moderately cold climate. © 2022 IEEE.
