The magnitude of these overvoltages depends on the power system voltage magnitude at the closing time and the trapped charge on the line. Surge arresters protect the energy equipment inside substations against the line overvoltages. The number of surge arrester operations is counted by the surge arrester counter. This article focuses on evaluating surge arrester performance in the transmission line switching. For this purpose, a 400 kV power transmission line in Iran is simulated using EMTP-RV software. Then, the probability of operation of the surge arrester counter is obtained using statistical switching. Comparing the recorded practical results by the surge arrester counter with the simulation results demonstrated that accurate simulation of the surge arrester performance requires modelling the corona in transmission lines. In addition, the impact of the transmission line structure on the performance of surge arresters is investigated. The simulation results indicate that if corona is taken into account in the modelling, the probability of counting by the surge arrester counter decreases from 98.6% to 4%. This result aligns with what has been observed in practice.","PeriodicalId":13261,"journal":{"name":"Iet Generation Transmission & Distribution","volume":"19 1","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ietresearch.onlinelibrary.wiley.com/doi/epdf/10.1049/gtd2.70206","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145686407","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this context, it is likely that multiple MGs will participate in the market. In light of the inherent unpredictability of wind power and other clean energy sources within each MG, a multi MG s electricity-carbon joint optimization operation method that considers robust market clearing is proposed. This method ensures the economic viability of the multi- MG s alliance while adhering to the principles of low-carbon operations and security. The constructed model comprises two layers. The upper layer establishes a robust clearing model of the upper-level electricity-carbon joint market with optimal accruals and benefits based on the marginal pricing theory. The lower layer considers the coupling of electricity-carbon joint trading, establishes a multi- MG s low-carbon joint optimization model based on the Nash negotiation theory, and proposes an electricity-carbon revenue allocation method based on the contribution degree of the interaction products to realize the reasonable allocation of the revenue of each MG. In conclusion, the accelerated-adaptive alternating direction multiplier method (AA-ADMM) is put forth as a means of solving the model.

However, most current studies considered different single technology to achieve this transition. Research on the interactive mechanisms between different carbon reduction measures remains limited. This paper proposes a capacity expansion planning model for a low-carbon power system that integrates multiple technologies, incorporating two complementary types of carbon reduction measures. Specifically, the technologies are categorized into two categories: direct CO2 reduction measures (e.g., carbon capture and storage) and indirect CO2 reduction measures (e.g., flexibility retrofit, energy storage system and wind expansion). Furthermore, a distributionally robust optimization method is developed to address the uncertainty of wind power. The column and constraint generation algorithm is employed to solve the model and derive the optimal planning scheme. Case studies based on the modified IEEE 24-bus system and the IEEE 118-bus system indicate that the proposed method significantly reduces both the system cost and carbon emissions. Additionally, the planning results demonstrate effective synergy between direct and indirect carbon reduction measures.","PeriodicalId":13261,"journal":{"name":"Iet Generation Transmission & Distribution","volume":"19 1","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ietresearch.onlinelibrary.wiley.com/doi/epdf/10.1049/gtd2.70198","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145626269","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditional evaluation methods, relying on predefined fault cases, iterative simulations, or heuristic techniques, often suffer from scalability challenges and computational burden. To address these limitations, this study presents a generalized, non-iterative analytical framework grounded in graph-theoretic principles. Building upon Lemma 1, which restates the classical reachability property of graph theory, where the n-th power of the adjacency matrix represents node connectivity, the method systematically identifies isolated nodes under diverse network topologies. Building upon this foundation, a fast distribution reliability calculator is developed and linked to each load point, enabling efficient calculation of reliability indices without extensive simulations. Unlike conventional approaches, the proposed framework inherently incorporates realistic modelling of key system elements, such as disconnectors, circuit breakers, remotely operated switches and distributed generation units. Its effectiveness is demonstrated on two networks, including Bus 6 of the 65-bus Roy Billinton test system and a real 778-node feeder located in Khorasan Razavi Province, Iran, where the results confirm superior accuracy and computational efficiency. Overall, the method offers a scalable and robust solution for evaluating the reliability and resilience of modern distribution networks.","PeriodicalId":13261,"journal":{"name":"Iet Generation Transmission & Distribution","volume":"19 1","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ietresearch.onlinelibrary.wiley.com/doi/epdf/10.1049/gtd2.70202","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145618986","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To limit loss of power transmission, protection systems based on DC circuit breakers (DCCBs) are envisioned. In case of grid-following wind turbine generators (WTG), DCCBs require large series reactors to avoid blocking of the offshore converter and subsequent shutdown of the offshore wind farm. By contrast, the potential of grid-forming WTG to ride through converter blocking during DC-side faults has not been investigated yet. Therefore, this paper compares four variations of WTG and HVDC converter control through detailed electromagnetic transient simulations of DC-side fault scenarios. It highlights that grid-forming WTG keep the offshore system in stable operation during temporary blocking of the offshore converter. Moreover, the paper shows that protection requirements can be reduced through the use of smaller DC series reactors. During temporary blocking, DC and offshore AC-fault-ride-through requirements are met but the AC power transfer to the onshore system is interrupted. Therefore, the temporary blocking time has to be chosen to adhere to current grid codes, with the active power return being dependent on the WTG. Already short blocking times of 10 ms can significantly reduce the inductance. However, that requires the fast deblocking to be in accordance with the internal protection mechanisms of the converter.","PeriodicalId":13261,"journal":{"name":"Iet Generation Transmission & Distribution","volume":"19 1","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ietresearch.onlinelibrary.wiley.com/doi/epdf/10.1049/gtd2.70189","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145581183","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Unlike conventional approaches that rely on probabilistic models, this research uses data-driven forecasting techniques to predict the output powers of wind and PV plants and uses them in the multi-objective optimisation algorithm to minimise costs and emissions. An arithmetic optimiser with a sine cosine assisted driving training-based optimisation algorithm (AOASC-DTBO) is presented to solve various single and multi-objective HDEED problems based on fuzzy decision-making and the Pareto dominance concept. The proposed dispatching algorithm is validated using 10-unit, 40-unit and 7-unit IEEE 57 bus systems. The results revealed that the AOASC-DTBO algorithm achieved 8.73% and 4.95% lower fuel costs when compared with the PSO and DTBO algorithms, respectively. In addition, the emissions were 6.47% and 2.25% lower than the BMO and DTBO algorithms, respectively. The work highlights the importance of integrating renewable energy sources (RES) into power systems to achieve cost savings and reduced emissions, while also emphasising the need for efficient dispatch algorithms to ensure grid stability and reliability. The results demonstrate that integrating RES into the power system can yield substantial economic and environmental benefits, achieving cost savings of up to $6,908.034 and reducing emissions by 13,233.691 tonnes per day.","PeriodicalId":13261,"journal":{"name":"Iet Generation Transmission & Distribution","volume":"19 1","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ietresearch.onlinelibrary.wiley.com/doi/epdf/10.1049/gtd2.70197","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145580910","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the weak feed-in characteristics and controlled phase angles of IBR output currents make distance protection more vulnerable to fault resistance, resulting in degraded performance. This paper proposes a distance protection scheme capable of fault location based on the coordination of control and protection. First, it is assumed that two linearly independent states exist in the system after a fault. Accordingly, a fault location calculation method is introduced, relying on the relationship among electrical quantities and current distribution coefficients in these two states. Second, a low-voltage ride-through (LVRT) strategy based on control switching is presented, whereby the IBR initially adopts active control to support positive-sequence directional detection and then switches to reactive-priority control to meet grid code (GC) requirements. Through control switching, two fault states are established. Third, to address the timing discrepancy in voltage drop detection between the IBR and relay protection, a coordination method of control and protection is optimized. Finally, a model of IBR outgoing lines is developed in PSCAD/EMTDC and RTDS simulation environments to validate both the coordinated method and the effectiveness of the proposed distance protection scheme.","PeriodicalId":13261,"journal":{"name":"Iet Generation Transmission & Distribution","volume":"19 1","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ietresearch.onlinelibrary.wiley.com/doi/epdf/10.1049/gtd2.70193","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145580690","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
