However, J-tubes hinder the heat dissipation and derate the cable ampacity. In this paper, using COMSOL Multiphysics 6.0 finite element simulation software, the model of <em>a</em> ± 400 kV DC submarine cable installed in J-tube is established. Simulation results reveal that the middle-upper part of the J-tube air section is the bottleneck position for the ampacity. Multiple factors, including the length of the air section, natural wind speed, and ambient temperature, are investigated to determine their influence on the ampacity of cables laid in J-tubes. Perforations on the side wall of the J-tube and the top platform for convective ventilation are proposed to enhance the ampacity. Additionally, the effects of certain influencing factors on the effectiveness of ventilation are analyzed, which indicate that adding openings on the side wall, increasing wind speed and lowering airflow temperature at the platform can improve the heat dissipation can greatly enhance the ampacity of the submarine cable. Under the most harsh summer conditions, the ampacity can be increased by at least 23.8 %. The research findings provide a new solution for guiding the design of J-tubes to enhance the ampacity of subsea cables in the J-tube segment.</div></div>","PeriodicalId":50547,"journal":{"name":"Electric Power Systems Research","volume":"244 ","pages":"Article 111562"},"PeriodicalIF":3.3,"publicationDate":"2025-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143478960","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The developed BHGC aims to minimize ripples in the charging and discharging currents. This converter can operate efficiently in both Grid-to-Vehicle (G2 V) and Vehicle-to-Grid (V2 G) modes, utilizing two energy sources viz. a utility grid and solar PV.

Despite advancement, significant research gaps persist in understanding the broader trends of risk analysis and exploring comprehensive technical risk indices. Existing studies often focus narrowly on specific measures, overlooking evolving dynamics in power systems risk management. This review addresses these gaps by systematically examining a range of risk measures, including underexplored indices such as loss of load expectation (LOLE), expected unserved energy (EUE), load ability limits (LAL), and energy expected not served (EENS), alongside commonly studied indices like voltage devotion and resilience. The review systematically addresses this challenge through three sections, ensuring a logical progression from introduction to analysis and findings. LOLE estimates the likelihood of power supply shortages, while EUE quantifies the expected energy not delivered due to outages. Additionally, underexplored metrics LAL and EENS analysis provide a more holistic view of system vulnerabilities. The study employs systematic reviews with bibliometrics analysis to identify key challenges, analyze academic research trends, and introduce methodologies, like failure mode and effects analysis (FMEA). FMEA identifies potential failure points, assesses their impacts, and integrates uncertainty and reliability into risk analysis, offering valuable insights into power system vulnerabilities. This approach ensures a detailed understanding of vulnerability, allowing for proactive measures in system reliability. The review is structured into three sections: an introduction to common technical risk indices, an exploration of challenges in current risk management, and an assessment of novel methodologies and their practical implications. Findings emphasize that indices like LOLE and EUE receive less attention compared to metrics like resilience and uncertainty. Furthermore, cost and time considerations in risk evaluation remain underexplored. This paper offers actionable insights for power companies to optimize operational planning and prioritize investments and enhance system reliability. Integrating underutilized indices with innovative methods like FMEA, this article provides a novel risk analysis framework that bridges theoretical gaps and supports practical decision-making.</div></div>","PeriodicalId":50547,"journal":{"name":"Electric Power Systems Research","volume":"244 ","pages":"Article 111534"},"PeriodicalIF":3.3,"publicationDate":"2025-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143453789","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
