Conventional proportional-integral (PI) control and first-order active disturbance rejection control face limitations in simultaneously achieving rapid dynamic response and robustness under complex disturbances. To overcome these challenges, a second-order active disturbance rejection controller (2-ADRC) is proposed for a nonlinear cathode gas path model. Unlike conventional ADRC, the 2-ADRC incorporates disturbance-derivative estimation into both the extended state observer and nonlinear state error feedback. This design improves the controller’s ability to compensate for rapidly varying disturbances and enhances transient performance. Simulation studies under multi-step load and OER commands, as well as in the presence of measurement noise, show that 2-ADRC outperforms PI and ADRC. Compared with PI, the integral of absolute error, integral of squared error, and total variation are reduced by 44.03 %, 7.27 %, and 42.40 %, respectively. Under noisy conditions, relative to ADRC, the reductions reach 64.5 %, 58.3 %, and 27.7 %. These results indicate the proposed method shortens rise and settling times, suppresses oscillations, and achieves smoother actuator responses. With millisecond-level real-time performance, 2-ADRC offers enhanced robustness and accuracy, making it promising for embedded ECU applications in fuel cell vehicles.</div></div>","PeriodicalId":56019,"journal":{"name":"Sustainable Energy Technologies and Assessments","volume":"83 ","pages":"Article 104583"},"PeriodicalIF":7.0,"publicationDate":"2025-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145097685","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}

At the highest input voltage (240 V) investigated, the N-fixation selectivity switches from nitrate to ammonium, which is the homologous N-product of urea.

While various energy system modeling methods are widely used for planning and decision-making, they each have their own strengths and weaknesses in capturing uncertainty in the outcomes of disruptive event modeling. This review addresses a critical research gap by systematically analyzing how such methods quantify and mitigate the impact of disruptive events on renewable energy supply. It is the first to comprehensively assess modeling approaches specifically in this context. The study categorizes 108 disruptive events from 102 articles into four primary types: natural (e.g., floods, heatwaves), human-caused intentional (e.g., technological innovations), socio-political (e.g., wars, policy changes), and economic (e.g., interest rate shifts, carbon tax changes). Articles were selected using a PRISMA-compliant methodology from multiple sources, applying strict inclusion criteria: relevance to renewable energy, a clear focus on disruptive events, and use of modeling methods. Findings confirm the hypothesis that incorporating broader socio-economic and environmental criteria into modeling improves the robustness and realism of planning under disruptive conditions. The review shows that relying on one modeling objective such as cost often limits the ability to capture uncertainty and stakeholder concerns. Instead, models that integrate multiple criteria and generate a range of feasible solutions offer more resilient and adaptable planning outcomes. The study recommends combining complementary modeling strategies and tailoring criteria to stakeholder priorities. Such combined modeling approaches are well suited to future studies, enabling flexible, risk-informed, and context-sensitive modeling of disruptive events in renewable energy supply systems.</div></div>","PeriodicalId":56019,"journal":{"name":"Sustainable Energy Technologies and Assessments","volume":"83 ","pages":"Article 104561"},"PeriodicalIF":7.0,"publicationDate":"2025-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145098257","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}
