Although DG integration improves efficiency by decreasing power losses, its deployment is frequently limited by technical constraints and financial considerations. Traditionally, network reconfiguration has been applied to loss optimization in distribution grids; however, in radial networks, its effectiveness is restricted because of the limited flexibility of power flow paths. Consequently, the combined application of DG placement and reconfiguration offers a more effective strategy for reducing active losses in contemporary distribution systems. During such optimization, it is crucial to include uncertainties in load and renewable generation to ensure realistic and stable results. In this context, the present study introduces a robust optimization framework designed to maintain reliable performance despite variations in generation and consumption. The proposed method ensures that optimal DG allocation and network configuration remain stable even under moderate fluctuations in system conditions. To evaluate its performance, both robust and deterministic formulations were run for a 70-bus system, and the obtained outcomes were compared with those reported in a reference study. The outcomes prove that the proposed approach significantly reduces daily energy losses under normal and uncertain operating conditions compared with the reference method.","PeriodicalId":100619,"journal":{"name":"IEEE Canadian Journal of Electrical and Computer Engineering","volume":"49 3","pages":"495-509"},"PeriodicalIF":1.6,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148626403","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To bridge this cognitive gap, this study proposes a novel retrieval-augmented generation (RAG) framework integrated with the operational traffic congestion prediction system (TCPS) in Taichung City. By leveraging large language models (LLMs) within a modular architecture, we introduce a hybrid retrieval mechanism that synergizes vector similarity search for unstructured real-time sensor streams and SQL augmentation for structured historical archives. This dual-path approach effectively mitigates common LLM limitations, such as hallucination and knowledge cutoff, by grounding responses in verified ITS data. Experimental evaluations on an expanded dataset of 150 queries demonstrate that the proposed system achieves a query resolution success rate of 88.7% and reduces information retrieval latency by approximately 40% compared to traditional dashboard navigation. These results confirm that the framework effectively transforms complex numerical forecasts into actionable natural language insights, significantly enhancing decision-making efficiency in smart city traffic management.","PeriodicalId":100619,"journal":{"name":"IEEE Canadian Journal of Electrical and Computer Engineering","volume":"49 3","pages":"333-343"},"PeriodicalIF":1.9,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148171811","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While effective, prior knowledge distillation (KD) methods face a critical challenge in harmonizing feature-based and logit-based philosophies, often providing either entangled knowledge or incomplete guidance for modern detectors. This research aims to address this gap by developing a comprehensive and unified distillation approach. By concurrently training teacher and student networks, the proposed method significantly improves the student model’s detection accuracy without adding extra computational demands during inference, as evidenced by identical parameter counts and floating-point operation per seconds (FLOPs). The research aims to develop a comprehensive and unified KD approach for visual object detection, leveraging teacher-guided attention to effectively balance feature-based and logit-based distillation methods. Knowledge transfer is optimized by distinctly separating the processes into localization distillation (LD) and classification distillation derived from feature maps. The robustness and strong generalization capabilities of this method are demonstrated through extensive experiments on the MS-COCO 2017 dataset, with comparisons against existing approaches. The results consistently show performance improvements across different model scales, achieving up to a 0.9% enhancement over baseline models.

However, megawatt-class pulsed power demands introduce severe voltage transients, and the constant power load (CPL) characteristics can lead to voltage collapse without fast energy support. Conventional droop-based energy storage system (ESS) control provides the steady-state voltage regulation but exhibits limited responsiveness to fast transients. This article presents a control-oriented design and analysis framework that combines droop control with virtual inertia control for a 6-kV class shipboard MVDC system under extreme pulsed-load conditions. The droop component provides sustained power support proportional to voltage deviation, while the virtual inertia component delivers a rapid response proportional to the voltage rate of change, enabling the complementary dynamic behavior. A second-order small-signal model is derived to characterize the system stability and damping properties as functions of control parameters. Simulation results demonstrate that, under a 15-MW pulsed load, the proposed scheme reduces the maximum voltage drop from 286 V (4.8%) to 182 V (3.0%), representing a 37% improvement over droop control alone, and eliminates voltage overshoot, reducing the total voltage deviation by 50%. The proposed method maintains consistent voltage performance under repetitive operation and ensures survivability under generator outage conditions. These results confirm that the proposed framework enables practical and robust parameterization of droop–virtual inertia control for MW-scale shipboard MVDC systems.","PeriodicalId":100619,"journal":{"name":"IEEE Canadian Journal of Electrical and Computer Engineering","volume":"49 3","pages":"418-431"},"PeriodicalIF":1.6,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148510826","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The research aims to address the challenges in analyzing the dynamic behavior and assessing the stability of systems where the strong nonlinearity of current limiting links is prominent. By adopting a generalized state-space modeling framework and incorporating a continuous approximation of the limiter’s nonsmooth characteristics using a hyperbolic tangent function, a nonlinear time-invariant model capable of describing the controller’s saturation switching process is constructed. Based on this model, the bifurcation behaviors of the system under three typical scenarios—AC voltage variation, three-phase-to-ground fault, and grid impedance variation—are systematically analyzed using the numerical continuation method. The results demonstrate that the introduction of the current limiter significantly reduces the stable operating region of the system, inducing fold bifurcation and Hopf bifurcation, which lead to instability. Furthermore, key control parameters exhibit a complex influence on the bifurcation boundaries, and their optimized design can effectively enhance system stability. Simulations conducted in PSCAD/EMTDC validate the correctness of the proposed model and the bifurcation analysis conclusions, providing a theoretical basis for the parameter design and secure stable operation of VSG-controlled MMC-based high-voltage direct current (MMC-HVDC) systems.","PeriodicalId":100619,"journal":{"name":"IEEE Canadian Journal of Electrical and Computer Engineering","volume":"49 3","pages":"443-458"},"PeriodicalIF":1.6,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148510942","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since electrical loads vary with voltage levels and differ by consumer category, they can be represented by a combination of fixed-impedance, power, and current components. Identifying the proportion of these elements for each load category enables the formulation of more adaptive and realistic models for feeder reconfiguration and DG allocation. In this context, the current work introduces a mathematical framework that explicitly links load composition with consumer categories and reformulates a nonlinear polynomial load model into a tractable quadratic form suitable for linear solvers. The developed framework is evaluated on standard 16- and 118-bus distribution systems. For the 16-bus network, the flexible formulation achieved power losses of 66.4–67.08 kW, which closely match the exact nonlinear model results (66.9–67.04 kW) while reducing computation time from about 2000–2230 s to nearly 1.2 s. For the 118-bus system, losses of 410.05–470.03 kW were obtained, compared with 409.38–471.10 kW for the exact model, with processing time reduced from approximately 58 000–157 000 s to 26–68 s. According to the results, the suggested framework preserves high solution accuracy while providing orders-of-magnitude improvements in computational efficiency. The developed approach, therefore, offers a practical and flexible tool for real-time distribution network reconfiguration and DG planning under voltage-dependent and category-based load modeling.","PeriodicalId":100619,"journal":{"name":"IEEE Canadian Journal of Electrical and Computer Engineering","volume":"49 3","pages":"525-535"},"PeriodicalIF":1.6,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148628256","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This combination provides flexible per-band adjustment of center frequency and bandwidth without resorting to higher order mode sequencing or multilayer stacks often used in prior GGW implementations, thereby simplifying fabrication and assembly. A prototype addressing space-to-Earth downlink bands exhibits passbands centered at 19.0 and 20.75 GHz, with 3-dB bandwidths of 400 and 280 MHz, respectively, and insertion loss (IL) < 0.4 dB across both bands.
