An asymptotic domain adaptive detection method for abnormal targets in transmission lines under complex weather conditions is thus proposed in this paper. An approximate domain closer to the target domain is first constructed, utilizing an image style transfer method; this is followed by a proposed multilayer domain transfer method that integrates a spatial attention mechanism that causes the model to pay more attention to feature information of abnormal targets, further shortening the distance between approximate domain and target domain. Finally, a SAM strategy is introduced into the domain adaptive task, creating a detection model for abnormal targets of transmission lines that is driven to access additional effective domain invariant information to make the landscape of task loss function smoother. In this study, detailed experiments are thus carried out based on an abnormal target dataset from various transmission lines. Experimental results show that the method improves accuracy of abnormal target recognition under complex weather conditions to 91.97%, offering recognition accuracy obviously superior to a single-step domain adaptive SOTA method or a variety of SOTA-based edge detection models for abnormal targets in transmission lines, and thus displaying good application prospects.","PeriodicalId":10729,"journal":{"name":"CSEE Journal of Power and Energy Systems","volume":"12 5","pages":"2605-2617"},"PeriodicalIF":5.6,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10058889","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149131877","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It was found that the increase of reactive power exchanged on the tie line led to a decrease in the AC voltage amplitude of the healthy line during the SCF development stage. Hence, the probability of SCF increases due to the reactive power interaction. Besides, the voltage distortion components in AC voltage of healthy lines caused by harmonic interaction play a negative role in the commutation process, which may lead to SCF. Also, there is a nonlinear coupling between the effects of reactive power and harmonics on SCF. Thus, the reactive power impact index (RPII) and the voltage distortion index (VDI) are proposed to assess the degree of reactive power impact and voltage distortion of the DC line, respectively. Furthermore, the SCF prevention strategy of the MIDC system is proposed, which is realized by reducing the advance angle of the faulty line based on RPII and triggering the healthy line earlier based on VDI. Finally, the simulation models of the MIDC CIGRE benchmark system and Henan multi-infeed UHVDC system are built, and the effectiveness of the proposed SCF prevention strategy is verified under different fault types.","PeriodicalId":10729,"journal":{"name":"CSEE Journal of Power and Energy Systems","volume":"12 5","pages":"2425-2439"},"PeriodicalIF":5.6,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10520153","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149130900","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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, they still face challenges from the complex impacts of extreme weather and the need to guarantee the charging demands of electric vehicle (EV) users. Therefore, this paper proposes a resilience enhancement strategy for multi-microgrids with EVs under extreme weather conditions. First, a resilience assessment framework for multi-microgrids is constructed, which includes a decision model for EV charging and discharging patterns. By incorporating the participation factor of EVs, the decision model optimizes the vehicle-to-grid process to guarantee users' charging demands. Second, extreme weather models, including heavy precipitation, extreme high or low temperature, and strong wind, are established to quantify their impact on the resilience of multi-microgrids, which specifically characterize the probability of microgrid disconnection and internal generator shutdowns. Subsequently, to efficiently coordinate power transmission between multi-microgrids and internal resource management within each sub-microgrid, a hierarchical resilience enhancement strategy based on deep reinforcement learning is designed, which incorporates the hindsight experience replay mechanism, effectively improving the convergence of the algorithm in complex tasks to enhance system resilience. Finally, simulation results demonstrate that the strategy significantly enhances the resilience of multi-microgrids, reduces operation costs and guarantees EV users' demands.","PeriodicalId":10729,"journal":{"name":"CSEE Journal of Power and Energy Systems","volume":"12 5","pages":"2243-2256"},"PeriodicalIF":5.6,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11338150","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149131333","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Integrated sources enable improved power supply reliability. After the upstream device fails, the islanding scheme can restore power to the downstream DN. However, in the process of formulating the islanding scheme, complex constraints should be considered, such as ES sequential characteristics and secondary outage constraints for load requirements. These constraint couplings make power recovery complex in DN. A method for DN island partition with ES is proposed. The islanding problem is a hybrid integer backpack model that include two key steps: the largest island is quickly identified by checking whether the power supply is sufficient, and the identified islands are corrected by checking whether the power supply meets real-time balance. Inspired greedy algorithms solve previous sub-problems. The latter sub-problem can be converted to a mixed-integer linear planning model for easy solution. By solving these two sub-problems alternately, it can quickly formulate islanding schemes with clear physical significance. A case study is carried out on an improved PG&E 69-bus system. It has been verified that the method can significantly reduce calculation time under the premise of the island partition benefit.","PeriodicalId":10729,"journal":{"name":"CSEE Journal of Power and Energy Systems","volume":"12 5","pages":"2269-2281"},"PeriodicalIF":5.6,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10376000","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149133415","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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, there is still a lack of research on the over-thermal decomposition characteristics of SF<inf>6</inf>/N<inf>2</inf> at present, let alone its over-thermal decomposition mechanism. Therefore, in this paper, to explore the decomposition characteristics of SF<inf>6</inf>/N<inf>2</inf> at different fault temperatures, a large number of partial over-thermal fault experiments are conducted in the range of 550°C to 650°C. The experiment results show that the initial formation temperature of NF<inf>3</inf>is 575°C, while S containing products (SO<inf>2</inf>, SOF<inf>2</inf>, SOF<inf>4</inf>and SO<inf>2</inf>F<inf>2</inf>) are generated in large quantities under the same conditions, and nitrogen oxides (NO and NO<inf>2</inf>) are already generated at 550°C.

Hence, a commutation failure fault level calculation method under three-phase-to-ground faults considering multi-factor influence is proposed in this paper. First, transient time-domain response of DC current after fault is gained and DC current harmonics are calculated by Fast Fourier Transform. Then, AC current harmonics are estimated based on the coupling relationship of DC current and AC current of the inverter. Furthermore, supply voltage-time area and zero-crossing considering the harmonic voltage are estimated. Then, dynamic interaction between AC and DC system caused by constant extinction angle controller is considered by the power flow equation. Finally, discrete commutation processes are constructed based on commutation voltage-time area rule to determine occurrence of CF under different fault levels.

Assume the AMIN control identifies a converter valve's commutation margin falling below the minimum threshold under AC fault conditions. In that case, the converter valve will be fired immediately to prevent commutation failure. However, the existing AMIN control faces several issues such as slow response time, inaccurate calculations, and a negative impedance characteristic that can negatively impact the steady operation of the HVDC project. Therefore, this paper proposes an improved AMIN control using zero-sequence components and a current deviation term that provides quick and accurate calculations of the commutation margin by utilizing the zero-sequence component of three-phase voltages and considering the DC current changes during commutation. Additionally, employing the current deviation term helps to enhance the performance of the LCC-HVDC's control system. Our simulations show that the proposed improved AMIN control significantly enhances the first commutation failure immunity and lowers the probability of subsequent commutation failures, thereby facilitating the restoration of the LCC-HVDC project.","PeriodicalId":10729,"journal":{"name":"CSEE Journal of Power and Energy Systems","volume":"12 5","pages":"2489-2501"},"PeriodicalIF":5.6,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10520030","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149133719","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
