This article presents a comprehensive and production-ready optimization framework for vehicle-to-grid integration, addressing day-ahead pricing, battery degradation, and grid constraints through a mixed-integer linear programming formulation. Unlike existing approaches that often rely on aggregated vehicle behavior, our framework preserves the full topology of the charging station, maintaining vehicle-level granularity. This enables precise evaluation of both marginal costs and savings, enhancing the model’s practical relevance and deployment potential. Results from real-world fleet schedules and Italian market data show that both controlled charging and vehicle-to-grid achieve substantially lower costs than uncontrolled charging, with savings exceeding 35% in current scenarios. However, the cost gap between vehicle-to-grid and controlled charging remains narrow. These findings indicate that as battery pack prices continue to decline and energy markets evolve, vehicle-to-grid will become increasingly favorable for scheduled fleets.","PeriodicalId":52675,"journal":{"name":"IEEE Open Journal of the Industrial Electronics Society","volume":"6 ","pages":"1593-1602"},"PeriodicalIF":4.3,"publicationDate":"2025-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11176439","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145210063","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}

Since magnetic power scales with the square of <italic>B</i>, this fundamentally limits achievable power density. In practice, the average power density of state-of-the-art MHz magnetic designs remains around 70 W/cm³, far below the requirements of emerging applications. To overcome these limitations, we propose the unbalanced-flux concept, a new magnetic architecture that replaces the traditional balanced-flux design paradigm. This approach reduces core loss by approximately 70%, enabling operation at substantially higher <italic>B</i>. As a result, the concept achieves a threefold increase in power density compared to MHz-based designs. The approach is experimentally validated in a 1-kW, 380 V/48 V <italic>LLC</i> transformer prototype. With natural air cooling, the transformer delivers 750 W at a record 224 W/cm³. With a heatsink, it achieves 190 W/cm³ at 1 kW, with a peak efficiency of 94.6%.

Traditional PD detection methods, effective under 50/60 Hz sine wave excitation, face significant challenges in this context due to strong interference from the switching transients of power electronic devices. Most existing methods rely on antennas with ultrahigh frequency high-pass filters (typically around 500 MHz) to suppress switching noise, but this often leads to the loss of lower frequency PD information and results in lower detection sensitivity. Moreover, antenna-based detection requires removing the equipment enclosure to avoid electromagnetic shielding, making it suitable only for laboratory studies and impractical for industrial monitoring. In contrast, the proposed method detects PD signals through the electrical measurement circuit and applies a bidirectional long short-term memory network to filter out switching disturbances, enabling PD detection in the 100–500 MHz range without invasive procedures or the need for ultrahigh frequency filters. Experimental analysis reveals that PD events predominantly occur at the switching edges and are highly sensitive to excitation waveform transients. Shorter rise times lead to fewer but higher magnitude PD events, while longer rise times result in more frequent and lower magnitude discharges. The duty cycle also affects both PD distribution and discharge power. Space charge theory is used to explain the experimental results. The proposed approach can be further refined for future online or offline PD monitoring.","PeriodicalId":52675,"journal":{"name":"IEEE Open Journal of the Industrial Electronics Society","volume":"6 ","pages":"1508-1532"},"PeriodicalIF":4.3,"publicationDate":"2025-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11157702","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145141635","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}

For practical implementation, platforms ensuring real-time performance, safety, and security are crucial. AUTOSAR adaptive platform (AUTOSAR AP) meets these needs and is widely used in development. However, it is rarely utilized in research due to licensing and tool availability issues. Instead, robot operating system 2 (ROS 2) is the main platform for autonomous vehicle research. This gap between research and development platforms hinders the swift application of research outcomes, delaying the practical implementation of autonomous vehicles. In addition, software-defined vehicle requires flexible software development in cloud environment. To address these challenges, this article proposes AUTOSAR AP and ROS 2 collaboration framework for development in cloud environment. ROS 2 uses data distribution service for communication, while AUTOSAR AP employs scalable service-oriented middleware over IP. The proposed framework bridges these protocols through conversion, enabling seamless communication. The functionality and performance of the proposed bridge converter are verified through measurements. The proposed bridge converter supports communication between AUTOSAR AP and ROS 2 in cloud environment and allows easy use of ROS 2 tools.

Iterative cybersecurity testing (i.e., red-team testing or penetration testing) is indispensable to counter emerging attack vectors and to ensure dependability of critical infrastructure. Furthermore, these can be used to evaluate cybersecurity configuration, effectiveness of the cybersecurity measures against various attack vectors, and to train smart grid cybersecurity experts defending the system. Facilitating extensive experiments narrows the gap between academic research and production environment. A high-fidelity cyber range (a virtual cybersecurity testbed emulating smart grid systems) is vital as it is often infeasible to conduct such experiments and training using production environment. However, the design and implementation of cyber range requires extensive domain knowledge of physical and cyber aspect of the infrastructure. Furthermore, costs incurred for setup and maintenance of cyber range are significant. Moreover, most existing smart grid cyber ranges are designed as a one-off, proprietary system, and are limited in terms of configurability, accessibility, portability, and reproducibility. To address these challenges, an automated smart grid cyber range generation framework (Auto-SGCR) is presented in this article. Initially a human-/machine-friendly, XML-based modeling language called smart grid modeling language (SG-ML) was defined, which incorporates IEC 61850 system configuration language files. Subsequently, a tool chain to parse SG-ML model files and automatically instantiate a functional smart grid cyber range was developed. The developed SG-ML models can be easily shared and/or modified to reproduce or customize for any cyber range. The application of Auto-SGCR is demonstrated through case studies with large-scale substation models. The toolchain along with example SG-ML models have been open-sourced.","PeriodicalId":52675,"journal":{"name":"IEEE Open Journal of the Industrial Electronics Society","volume":"6 ","pages":"1575-1592"},"PeriodicalIF":4.3,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11145746","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145210089","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}

Thus, it remains an optimization challenge to ensure that PV systems operate at their global MPP (GMPP). Scanning the output characteristics of the PV panels seems a general solution for this issue. However, applying a short circuit to the terminal of PV panels where there exists an electrolytic capacitor, has a detrimental effect on the lifetime of the system. To this end, in this article, a GMPP estimator is proposed as a global solution for conventional maximum power point tracking (MPPT) algorithms under PS conditions. The proposed technique improves existing simple MPPT algorithms with original approaches as follows: first, an accurate microscopic analysis of a PV characteristic in PS conditions is considered, second, an original definition of the dominant cells and modules in a PV panel is proposed that allows to reduce the PS patterns to a finite number, and third, the search area for the MPPT operation is reduced to find the accurate GMPP by proposing two voltage boundaries. The lower boundary corresponds to the GMPP under uniform shading condition that can be determined using a closed form formula, while the upper one refers to the GMPP of a dominant cell in a PV module that can be determined using an artificial intelligence technique. This can also help set the initial duty cycle in a convex area around the GMPP. The functionality of the proposed GMPP estimator is experimentally validated.","PeriodicalId":52675,"journal":{"name":"IEEE Open Journal of the Industrial Electronics Society","volume":"6 ","pages":"1387-1397"},"PeriodicalIF":4.3,"publicationDate":"2025-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11134809","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144998362","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 article reports the experience we have gained developing a driver distraction detection (DDD) system within the Hi-Drive research project on driving automation. Targeting on-board deployability, we have faced several leading-edge research issues that have not been addressed together in published research works. We propose a compact sensory configuration and a limited computational resource system architecture, also exploiting careful manual and automated labeling, trying to find a tradeoff among conflicting needs in terms of accuracy, privacy preservation, energy efficiency, and costs. Our system detects two levels of insufficient attention, which are keys not only for designing a proper driver warning and information management strategy but also for better managing the transition among different automation levels. Our experiments confirmed on real-world data, and in the three-class task, the importance of distinguishing users among training, validation, and testing to prevent overestimating model performance by overfitting individual participant patterns present in all three subsets. We analyzed the complexity of the three-class problem, which is also related to the relatively low representation of the intermediate distraction class in the dataset. We showed that the size of the classifiable time window is a critical performance factor and found that a 5 s length seems to achieve the best tradeoff between latency, time resolution, and the need for capturing sufficient temporal information to detect distraction. Another empirical finding comes from a SHAP values-based explainability analysis and concerns the importance of vehicular signals for the detection task, particularly in the three-class problem. This is significant, as such signals are inexpensively available in vehicles, and their processing does not add further privacy concerns. Finally, assessing performance on three state-of-the-art embedded platforms, we observed that the developed deep learning models are able to effectively run on limited-resource, on-board deployable devices, meeting real-time performance requirements, also on a mainstream, low-cost microcontroller. We argue that these findings open significant perspectives toward an effective and efficient field deployment of DDD electronic systems.","PeriodicalId":52675,"journal":{"name":"IEEE Open Journal of the Industrial Electronics Society","volume":"6 ","pages":"1351-1369"},"PeriodicalIF":4.3,"publicationDate":"2025-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11134568","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144990057","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}
