In practical applications, the operation of the T-type rectifier under unbalanced three-phase grid conditions must be considered. This article establishes an improved direct power control structure based on extended power theory under unbalanced grid conditions to achieve distortion-free current for the T-type rectifier. Additionally, a feedforward virtual capacitor power compensation is created to eliminate the output voltage ripples caused by the ripple power of the rectifier inductance under the unbalanced three-phase grid. The controller design of the improved direct power control and the choice of the virtual capacitor are analyzed. Furthermore, the proposed method regulates the neutral point voltage of the T-type rectifier, eliminates neutral point current disturbances, and provides a stable and accurate dc output voltage, ensuring high quality power supply. The proposed strategy does not require a phase-locked loop or ac-side system parameters, resulting in excellent dynamic performance and robustness against parameter mismatches. Finally, the effectiveness and feasibility of the proposed control strategy are verified through simulation results and the implementation of a 2.4 kW three-phase T-type rectifier.","PeriodicalId":52675,"journal":{"name":"IEEE Open Journal of the Industrial Electronics Society","volume":"6 ","pages":"429-444"},"PeriodicalIF":5.2,"publicationDate":"2025-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10918756","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143698288","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This problem does not arise in DC electrification systems. The aim of this article is to introduce a novel Grid-Forming control strategy, which applied to a power electronics based topology allows the generation of an AC catenary from the DC catenary. Focusing on the capabilities of the control algorithm, the system is presented as a fully scalable solution employing multiple grid-forming DC/AC converters. These converters use power control loops based on the Virtual Synchronous Machine concept, adapted to single-phase operation. A key advantage of this approach is that all converters within the system contribute to supporting both voltage and frequency stability. In addition, the implementation does not require a higher-level controller or communication system. Through an appropriate power control design, the power supplied by each converter, relative to the total load demand, can be determined.","PeriodicalId":52675,"journal":{"name":"IEEE Open Journal of the Industrial Electronics Society","volume":"6 ","pages":"445-458"},"PeriodicalIF":5.2,"publicationDate":"2025-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10914004","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143706582","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The MMPC incorporates feedforward reference compensation (FFRC) and a posterior constraint compensation (PCC) technique. When the motor operates on a nonconstant velocity profile, the FFRC technique reduces the tracking delay associated with conventional MPC methods. In addition, the PCC technique addresses control signal constraints under a step velocity profile without requiring the solution of complex optimization problems at each time step, thereby reducing the computational effort for the controller. Furthermore, the ASDO utilizes a second-order disturbance observer to enhance the robustness of the MMPC. An adaptive observer bandwidth algorithm is proposed to minimize random noise and current ripple. The performance of the proposed methods was evaluated by applying them to an industrial motor drive, confirming their validity and practicality in real-world operations.","PeriodicalId":52675,"journal":{"name":"IEEE Open Journal of the Industrial Electronics Society","volume":"6 ","pages":"415-428"},"PeriodicalIF":5.2,"publicationDate":"2025-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10909597","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143667294","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Coordinating distributed generators (DGs) is complex, so communication-based controllers are proliferating in the literature. Then, this work proposes a distributed control strategy for islanded ac/dc multi-MGs interconnected by interlinking converters (ILCs). The proposed scheme is implemented in the ILCs and consists of distributed controllers that equalize global generation costs, allowing secondary control in each MG. Control actions that safeguard the saturated operation of MGs and ILCs are included in the control designs. The simultaneous operation with multiple objectives is possible due to adjusting control parameters according to a prioritization criterion. Experiments are conducted through an extensive simulated environment. The results show the proposed multiobjective controllers could maintain global optimal costs during normal operation while not overloading DGs, ILCs, subgrids, and clusters of ILCs. Furthermore, the strategy may reduce operational costs in the long term by protecting the lifetime of critical MG components. Desynchronization of incremental costs is enforced at 15% at most under demanding conditions. Also, it is possible to operate against considerable (<inline-formula><tex-math>$>$</tex-math></inline-formula>250 [ms]) time delays in the tests.","PeriodicalId":52675,"journal":{"name":"IEEE Open Journal of the Industrial Electronics Society","volume":"6 ","pages":"358-379"},"PeriodicalIF":5.2,"publicationDate":"2025-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10909984","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143621685","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, security measures, often implemented late in the engineering process, lead to costly and complicated implementations. Thus, this article is concerned with the “security by design” principle in ICSs and facilitates compliance with ICS security standards, which can be legally mandated for some critical systems or adopted by asset owners to protect their assets. Current methods for compliance demand manual efforts from security experts, making the compliance process time-consuming and costly. To address this, we propose a framework for leveraging large language models (LLMs) combined with knowledge graphs to automate the interpretation of security requirements and system architecture as two main elements of the design phase. Our knowledge graph-augmented LLM framework converts system architectures into human natural language, enhancing the automation of various security analyses, especially those that need to handle textual requirements. The framework enables validating applicable security requirements provided by IEC 62443-3-3 (a widely-used ICS security standard) concerning system designs through a question-and-answer interface. To evaluate the framework, various questions with reference responses from human experts were prepared in the context of a use case, and the quality of the LLMs' responses was measured across various metrics. Moreover, we compared the framework with a baseline approach based on formal queries. The results show that the proposed framework effectively automates security tasks and offers a user-friendly interface accessible to nonexperts.","PeriodicalId":52675,"journal":{"name":"IEEE Open Journal of the Industrial Electronics Society","volume":"6 ","pages":"380-395"},"PeriodicalIF":5.2,"publicationDate":"2025-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10904297","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143637936","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
