Furthermore, the impact of key factors, namely, initial recovery voltage gradient, fault location, line length, and injection power compensation delay time on the suppression effect has been analyzed. The results reveal that the injection power compensation-based method reduces the recovery voltage by 24.7% and shortens the average arc duration along the transmission line under 600 km by 22% compared to two groups utilizing high-speed grounding switches. Notably, fault location demonstrates a trend where the effect is superior at both ends of the line. The enhancement of other factors diminishes the suppression effect. Although the proposed method shows promise, further practical research is warranted to fully validate its feasibility.","PeriodicalId":13498,"journal":{"name":"IEEE Transactions on Power Delivery","volume":"40 2","pages":"878-888"},"PeriodicalIF":3.8,"publicationDate":"2025-01-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142936200","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our previous work has been taken as a basis, where a PEV coordination methodology is proposed to minimize the Loss of Life (LOL) of Primary Distribution Transformers (PDTs) in the network supplying the charging of a set of PEVs. In the first stage, the charging power profiles of PEV aggregators, which are favorable for the Distribution System Operator (DSO), are calculated. Then, in the second stage, time-bands of TOU tariffs are computed for each aggregator to incentivize PEV charging in accordance with the result of the first stage. Such time-bands mitigate the increase in aggregator energy costs due to PEV charging coordination. Finally, in the third stage, the obtained TOU tariffs are applied to the PEV coordination methodology. The proposed methodology has been applied to a case study involving 32 aggregators. Results indicate that the increase in aggregator costs due to PDT power limitation is relatively small, while the reduction in LOL of PDT is significant.","PeriodicalId":13498,"journal":{"name":"IEEE Transactions on Power Delivery","volume":"40 2","pages":"822-830"},"PeriodicalIF":3.8,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142912178","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Firstly, sixteen types of gassing materials were prepared using PA6 and PA66 as matrices, with various flame retardants and reinforcements as additives. Breaking experiments were conducted in both low-frequency and direct-current circuits to assess these materials in terms of arcing and post-arc phenomena. Material characterization techniques were then employed to analyze the optical absorption and pyrolysis properties of the selected gassing materials. Finally, based on the physical mechanisms of interaction between arcs and gassing materials, a detailed mechanistic analysis and theoretical explanation were provided, integrating material characterization and microscopic modeling. The results suggest that the proposed evaluation method effectively identifies one or two materials with optimal overall performance from the 16 types tested. Superior materials are characterized by organic molecular fillers and high radiation absorption, which enhance arc energy absorption and increase ablation gas generation.

To more effectively reduce the occurrence of such accidents, this paper proposes a monocular vision-based method for monitoring the safety distance between personnel and live equipment. Firstly, this paper makes lightweight improvements to the YOLOv8 (You Only Look Once) keypoint detection model by introducing the proposed dense feature fusion (DFF) module and adaptive channel cross (ACC) module into the backbone and neck, respectively, and replacing the network's original path aggregation network (PAN) structure with the bi-directional feature pyramid network (BiFPN) structure. Subsequently, based on the principles of camera imaging and perspective geometry, this paper calculates the mapping relationship between two-dimensional pixel coordinates and three-dimensional world coordinates. Finally, based on the detected keypoints and the obtained mapping relationship, the distance between personnel and live equipment is monitored. Experiments conducted in a substation scenario show that the improved keypoint detection model increases AP from 0.718 to 0.771, reduces parameters from 3.09M to 2.10M, and lowers FLOPs from 8.48G to 7.01G, and the maximum distance measurement error is only 3.778%.","PeriodicalId":13498,"journal":{"name":"IEEE Transactions on Power Delivery","volume":"40 2","pages":"810-821"},"PeriodicalIF":3.8,"publicationDate":"2024-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142887471","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Existing methods for obtaining detailed analytic expressions of the impedance equivalents are time consuming and reliant on extensive algebraic manipulation of numerous equations. In this context, this paper presents a method for calculating impedance profiles numerically, by using a descriptor state-space (DSS) representation of the IBRs which considers all IBR control blocks modularly, so that they can be added, removed, or modified without extensive algebraic manipulations. The method is based on DSS models, which are more transparent than traditional state-space models as algebraic expressions are modeled explicitly. This modular approach speeds up the investigation of the impact of different control designs and tunings on the risk of instabilities, while preserving a high level of detail of IBR behavior and mitigating potential human error. The proposed calculation methodology is validated with detailed electromagnetic transient simulations, for single-phase and three-phase IBRs. Applications of the proposed approach are presented to illustrate its ability to assist on the efficient investigation of characteristics of different control designs, and to help identify simplified models tailored for studying specific types of instabilities at different frequency ranges.","PeriodicalId":13498,"journal":{"name":"IEEE Transactions on Power Delivery","volume":"40 2","pages":"764-775"},"PeriodicalIF":3.8,"publicationDate":"2024-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142879703","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The integration of non-dispatchable renewable energy sources like wind and solar, which are known for their variability, poses challenges to frequency management due to decreased system inertia. Consequently, there is a need for a comprehensive UFLS relay scheme tailored to renewable energy-integrated systems, aiming to enhance reliability and stability while minimizing unnecessary load shedding during under frequency events caused by unpredictable renewable sources. In this research paper, we present an optimal and robust multi-stage UFLS scheme designed for two operating points: base-load and peak-load. The suggested scheme considers different levels of wind power penetration and incorporates various contingency scenarios. The proposed UFLS scheme assumes that wind turbines are equipped with auxiliary controllers to actively participate in the power system frequency control task. To optimize the scheme, a genetic algorithm (GA) is employed, and the performance is evaluated through simulations using MATLAB and DIgSILENT/PowerFactory link. The results of the study demonstrate that the involvement of wind turbines in the frequency response significantly improves the performance of the UFLS scheme and reduces the total amount of load shedding required. This research provides valuable insights into addressing the challenges posed by renewable energy integration and offers a potential solution to enhance the reliability and stability of power systems in the presence of renewable sources.","PeriodicalId":13498,"journal":{"name":"IEEE Transactions on Power Delivery","volume":"40 2","pages":"681-692"},"PeriodicalIF":3.8,"publicationDate":"2024-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142867129","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a potential solution to alleviate the strain on existing distribution networks, the adoption of Low Voltage Direct Current (LVDC) distribution networks is under consideration.

Several protection algorithms focus on significant fault currents, fixed threshold settings, and high sampling frequencies for effective coordination, which often face limitations in low fault current scenarios or require costly data acquisition techniques. Therefore, this paper presents a novel centralized Post-Transient Derivatives (PTD) based protection scheme, which Leverages only the sign of Post-Transient Voltage Derivative (PTVD) and Post-Transient Current Derivative (PTCD).
