With the development of technologies such as renewable energy and HVDC (high voltage direct current) transmission, the power system is gradually moving towards a trend of high penetration of renewable energy and a high proportion of power electronic devices. As a result, the mechanism of transient voltage stability is becoming increasingly complex, posing serious challenges to transient voltage stability analysis. Therefore, it is of great importance to quickly and effectively assess and quantify transient voltage stability for the safe and stable operation of the system. This paper first explores the concept of transient voltage stability, and then provides a detailed review and analysis of transient voltage stability practical criteria in various countries and regions, summarizing a more adaptable and practical three-stage transient voltage stability criterion. Additionally, it also classifies and summarizes existing transient voltage stability assessment indices and highlights three key aspects in the future research of the indices.","PeriodicalId":13261,"journal":{"name":"Iet Generation Transmission & Distribution","volume":"19 1","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ietresearch.onlinelibrary.wiley.com/doi/epdf/10.1049/gtd2.70166","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145223764","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}

The proposed approach uses the linear matrix inequality (LMI) for polytopic linear parameter varying (P-LPV) modelling based on the H∞ control theory and principal component analysis (PCA) algorithm. The objective is to regulate the MG frequency while considering the nonlinearity and uncertainty of the system. To achieve optimal control gains, the method considers all the system uncertainties in a P-LPV modelling of the system. The PCA algorithm reduces the scheduling parameter region, and the optimal control gains are computed by solving the relevant LMIs defined on the obtained P-LPV model based on H∞ performance and stability achievement. The primary control gains are optimised to minimise the errors between the optimal and actual control signals. Importantly, the suggested method preserves the order and structure of the primary control, making it applicable to implement on digital hardware devices. In addition, the MG is simulated in MATLAB/Simulink, and the simulation results demonstrate the authenticity, effectiveness, and efficiency of the proposed process for MG frequency regulation in the presence of uncertainties, disturbances, nonlinearity, and dynamic changes in MGs.","PeriodicalId":13261,"journal":{"name":"Iet Generation Transmission & Distribution","volume":"19 1","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ietresearch.onlinelibrary.wiley.com/doi/epdf/10.1049/gtd2.70171","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145223763","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, traditional methods often fail to comprehensively and efficiently consider fault scenarios before disasters, and the inefficient challenge of addressing large-scale post-disaster recovery problems necessitate advanced computational approaches. This paper proposes a quantum-assisted resilience enhancement framework for power distribution systems with NMGs, fully accounting for potential failure risks. The main contributions include a two-stage quantum-assisted resilience enhancement framework that integrates quantum amplitude estimation (QAE) for quantifying failure risks, and generating scenarios, the quantum-encoded model establishment, and the proposed quantum surrogate absolute-value Lagrangian relaxation (Q-SAVLR) algorithm for achieving quantum-accelerated parallel optimization. Numerical tests on a modified IEEE system show that our approach reduces computation time by roughly 40%–75% relative to the classical solver, enabling faster repair resource deployment and more efficient resilience optimization for NMGs.","PeriodicalId":13261,"journal":{"name":"Iet Generation Transmission & Distribution","volume":"19 1","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ietresearch.onlinelibrary.wiley.com/doi/epdf/10.1049/gtd2.70158","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145146417","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}

The CSE framework additionally addresses the challenges related to balanced bus requirements within distribution system state estimation (DSSE). Specifically, the CSE method models a transmission boundary bus as a reference bus for the execution of DSSE. Furthermore, the methodology constructs a consistency check vector based on the estimated variables of the modelled reference bus, thereby ensuring the coherence of the solution for the entire power system. To manage the substantial complexity of the problem, the CSE approach employs a parallel estimation strategy. This paper validates the CSE technique through a comprehensive analysis of different power transmission and distribution system combinations. The study focuses on the IEEE 14-bus and New England 39-bus systems as transmission networks, alongside the IEEE 13-node and 37-node feeders as distribution networks.

Network operators commonly use the concept to quantify the ability of their networks to accept new production and consumption. Academic research on hosting capacity took off seriously after 2010 and has resulted in thousands of publications. This paper presents a brief history of the early years of hosting capacity studies, gives an overview of the status of both applications and research, summarises the different methods and types of studies, and correlates all that with the underlying fundamental principles of the hosting capacity concept, as it was introduced in 2004. The main focus of this paper is to review and relate these methods and studies to the fundamental principles. Having a clear understanding of these fundamental principles enables a wide range of applications for hosting capacity studies with detailed methods and models. However, it also requires transparency to ensure a coherent analysis, correct interpretation of the results, and an open discussion between stakeholders. With research on hosting capacity, it is important to refer to the fundamental principles; with applications, it is important to maintain transparency and objectivity.","PeriodicalId":13261,"journal":{"name":"Iet Generation Transmission & Distribution","volume":"19 1","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ietresearch.onlinelibrary.wiley.com/doi/epdf/10.1049/gtd2.70112","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145146750","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}

Air conditioning (AC) load, as a critical demand response resource, has garnered increasing attention. However, existing AC load control strategies are either heavily influenced by user behaviour uncertainty or overly reliant on communication and measurement infrastructure. Moreover, most approaches adopt random switching control methods, which fail to maximise user participation willingness and overlook the dynamic variations in user responsiveness, ultimately limiting their practical effectiveness. To address these challenges, this study proposes a dynamic scheduling model that comprehensively considers the aggregated response potential of AC loads and the characteristics of multiple flexible load types, thereby fully exploiting the coordinated regulation capability of load-side resources. Targeting a low-carbon community scenario (incorporating distributed wind power and residential users), the model is formulated with the dual objectives of maximising wind power accommodation and minimising source-load power deviation. A greedy algorithm is employed to iteratively solve the maximum available response capacity and actual dispatchable quantity of AC loads in each time slot, enabling dynamic updates of potential assessment and scheduling decisions. Case studies validate the effectiveness of the proposed model in enhancing wind power utilisation and optimising load scheduling, providing a feasible solution for source-load coordination in modern power systems.","PeriodicalId":13261,"journal":{"name":"Iet Generation Transmission & Distribution","volume":"19 1","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ietresearch.onlinelibrary.wiley.com/doi/epdf/10.1049/gtd2.70159","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145146401","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}

The following research work is conducted: first, a reliability function for hybrid modular multi-level converters (MMCs) is developed based on actual topological structures, with sub-module (SM) correlation and redundancy configurations comprehensively considered. Moreover, various SOP ports fault scenarios and their corresponding control strategies for distribution network faults are analysed, and an improved virtual flow method is proposed to satisfy network radiality and connectivity constraints during load restoration. On this basis, a mixed-integer second-order cone programming (MISOCP) model for FIDN load restoration is formulated, aiming to maximise load restoration through multi-device coordinated output. Furthermore, load nodes are classified based on their restorability post-fault, and optimal load restoration is performed under fault scenarios generated by Monte Carlo sampling, with system reliability indices further calculated. Finally, the effectiveness of the proposed method is validated on a modified 37-node system and the modified IEEE 123-node test system.","PeriodicalId":13261,"journal":{"name":"Iet Generation Transmission & Distribution","volume":"19 1","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ietresearch.onlinelibrary.wiley.com/doi/epdf/10.1049/gtd2.70160","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145129295","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}
