Multiport converters (MPCs) are an efficient, unified solution to aggregate diverse resources and enhance system resilience. This article proposes a multistage design of MPCs. An optimization-based methodology is presented for optimally sizing the MPC terminals, minimizing total economic cost while simultaneously optimizing technical indicators such as annual line losses and voltage stability. This methodology is validated across two distinct utility use cases: a four-terminal MPC in an LV network, which successfully integrates photovoltaic (PV) generation and EV charging, and a two-terminal MPC in an MV network thateffectively mitigates voltage imbalances between parallel feeders. Furthermore, the work reviews suitable MPC topologies for these grid applications and proposes a qualitative comparison technique implemented in a MV application.

Consequently, due to inherent limitations in testing capabilities and the associated safety hazards, systematic studies investigating arc voltage and pressure transients within on-load tap-changers during actual arc fault events, as well as comprehensive assessments of their explosion-proof performance, remain relatively scarce in the existing literature. In view of this, this article first identifies the pressure relief device and top cover strength as critical factors for on-load tap-changers explosion protection, based on two preliminary arc fault tests. Subsequently, it investigates on-load tap changer explosion-proof strategies through computational fluid dynamics and explicit dynamic simulations. The results show that the reinforced top cover reduces the maximum displacement by 76.8% (from 1.83 mm to 0.42 mm) under impact. Finally, a prototype is manufactured and subjected to a high-energy arc fault test with an energy of 5.51 MJ, during which the peak internal oil pressure reaches 5.19 MPa without top cover rupture or fire ignition, validating the effectiveness of the proposed explosion-proof measures. This article represents the first arc fault test conducted on an OLTC equipped with a diverter switch and provides valuable data for the study of arc characteristics within OLTCs under high-energy faults, and offers a reliable solution for OLTC explosion protection.","PeriodicalId":100629,"journal":{"name":"IEEE Open Journal of Industry Applications","volume":"7 ","pages":"396-407"},"PeriodicalIF":3.3,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11421808","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147557785","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, the existing neural network-based intrusion detection frameworks exhibit limited robustness against malicious threats. Furthermore, these frameworks struggle to effectively manage the pronounced class imbalance inherent in cybersecurity datasets. In response to these challenges, this paper presents a novel feature-adaptive asymmetric dynamic reweighting ensemble graph neural network for network intrusion detection systems in power grids. Our methodology introduces several novel contributions: first adaptive graph construction techniques that provide stronger connectivity for underrepresented classes, second asymmetric model capacity allocation that dedicates more representational power to challenging classifications, and third dynamic loss weighting strategies that evolve during the training process. The proposed framework incorporates an ensemble of diverse graph neural network models with varying architectures. This ensemble significantly improves the detection of normal network traffic while maintaining high accuracy for attack identification. Experimental results demonstrate that our approach achieves more balanced per-class performance compared to traditional models, with a 15%–20% improvement in minority class detection accuracy. Synthetic minority oversampling technique oversampling, specialized interaction features, and nonlinear transformations were implemented to further enhance model robustness. The ensemble’s voting mechanism provides additional resilience against misclassification. This makes the approach particularly valuable for real-world intrusion detection systems that must maintain high detection rates across all traffic types.","PeriodicalId":100629,"journal":{"name":"IEEE Open Journal of Industry Applications","volume":"7 ","pages":"458-473"},"PeriodicalIF":3.3,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11442954","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147606201","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 main advantage of inverter control—its ability to control frequency and phase independently—over conventional synchronous machine behavior is emphasized. This additional degree of freedom is used to implement an intrinsically damped response to grid disturbances such as voltage steps, frequency deviations, and phase jumps. The proposed control is analyzed in the state-space for three representative operating scenarios: grid parallel operation, two weakly coupled power resources, and a two-area system with two resources per area. A design goal for the control gain is formulated and applied to the operating scenarios under consideration, using only characteristic per-unit quantities and time constants. It is shown that the damping coefficient at the boundary case of all real-valued poles mainly depends on the intrinsic parameters of the power resource, such as short-circuit impedance and filter time constants, and is fairly independent of other system parameters. Simulation results confirm the analytical design of the damping coefficient, using a two-area system as a benchmark case. In comparison to conventional power plants, the proposed grid-forming control with an optimized damping coefficient demonstrates a significantly improved damped response to grid events, such as load or generation changes or partial tie line tripping. Experimental results gained in a complex power system laboratory validate the well-damped behavior for typical grid events.","PeriodicalId":100629,"journal":{"name":"IEEE Open Journal of Industry Applications","volume":"7 ","pages":"658-673"},"PeriodicalIF":3.8,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11585951","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148490644","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}
