To preserve operational security, system operators often impose stringent requirements that can necessitate RES curtailment, particularly during periods of low demand. While such measures predominantly affect large-scale distributed energy resources (DERs), prolonged curtailment scenarios may also compel output reductions from numerous small-scale, often uncontrollable, DERs (UDERs). Prevailing control strategies for UDERs typically rely on the deployment of dedicated control and communication hardware at each UDER site, incurring significant capital expenditure and implementation complexity. This paper introduces a novel methodology for the coordinated curtailment of UDERs, which circumvents the need for such supplementary equipment. The proposed approach utilizes the system frequency as an implicit communication conduit, leveraging the inherent active power-frequency (P-f) response capabilities of UDER inverters. A data-driven framework is employed to optimize a global active power-frequency reduction characteristic, tailored from historical operational data. This characteristic is subsequently implemented in a decentralized manner by individual UDERs, thereby effectively mitigating investment costs and cybersecurity vulnerabilities associated with conventional control architectures. The performance and efficacy of the proposed methodology are demonstrated through dynamic simulations on a model of the isolated, low-inertia power system of Cyprus.</div></div>","PeriodicalId":56142,"journal":{"name":"Sustainable Energy Grids & Networks","volume":"45 ","pages":"Article 102124"},"PeriodicalIF":5.6,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146077422","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}

These methodologies require urgent reform. This article reviews the economic theory and European experiences regarding the allocation of system costs and puts forward a comprehensive high-level proposal to improve the design of these charges. Balancing capacity costs should be partially embedded in the imbalance price, with price caps limiting the possibility of very high prices during periods of low imbalance volumes. Congestion management costs, like network expansion costs, are driven by transmission capacity scarcity and should be recovered through network tariffs. Any system costs that cannot be allocated according to cost causality should be recovered through stabilised residual charges that do not distort the efficient signals sent by cost-reflective charges and prices. Discounts and exemptions for certain categories of end users should only apply to these residual charges.

The lack of coordination between connection requests is making the process time-consuming and also creating virtual congestion in the network, hindering further investments. With the development of advanced analytical tools and increased observability, Distribution System Operators (DSOs) are starting to adopt new planning and operational approaches. Calculating a network’s hosting capacity (HC) is one of the most investigated planning concepts in modern power systems. However, HC is a conservative approach that considers worst-case scenarios, thereby limiting new connections to the network. This has created the need to develop the dynamic operating envelopes (DOE) concept. DOEs are envisioned as the concept bridging the gap between planning and operational phases, as well as an approach to test the relaxation of conservative fixed connection rules defined in national grid codes. A step further is the near real-time upgrade of DOE defined as P-Q flexibility regions, improving the previous concepts by estimating system-level service provision capabilities. The concept is based on controlling active and reactive power and, consequently, increasing system’s flexibility. The paper contributes in the form of an extensive review of modeling techniques and algorithms, defining the necessary dataset for each of the concepts and models. Furthermore, it discusses the importance of including various technical constraints. Additionally, the paper identifies necessary improvements in data collection to properly assess the value and constraints of DER providing services to the distribution system.</div></div>","PeriodicalId":56142,"journal":{"name":"Sustainable Energy Grids & Networks","volume":"45 ","pages":"Article 102070"},"PeriodicalIF":5.6,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145685699","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}

However, accurately estimating their State of Health (SOH) remains a major challenge, as battery degradation is governed by complex electrochemical and thermal processes influenced by dynamic operating conditions. Although numerous machine learning (ML) approaches have been proposed, many existing methods rely on narrowly scoped datasets, struggle with nonlinear degradation behavior, or lack robustness under real-world variability. These limitations hinder their applicability in large-scale sustainable energy systems. To address these gaps, this study introduces an Ensemble Stacking Regressor designed to provide accurate, generalizable, and noise-resilient SOH estimation. The framework integrates Extreme Gradient Boosting Random Forest (XGBRF), Histogram-based Gradient Boosting Regressor (HGBR), and Extra Trees Regressor (ETR), combined through a Support Vector Regression (SVR) meta-model. Extensive feature extraction from voltage, current, temperature, and internal resistance profiles enables the model to capture multi-dimensional degradation patterns essential for reliable SOH assessment. Experimental results on four MIT battery datasets reveal consistently high accuracy, with R² values above 0.990 and low RMSE, MAE, and RSE metrics. Additional validation on NASA and Oxford datasets confirms strong generalization, while noise-perturbation tests demonstrate high resilience under uncertain measurement conditions. These findings indicate that the proposed framework could enhance battery reliability, support smarter energy management strategies, and strengthen the integration of EVs and storage systems into sustainable energy networks. The model can offer a robust and transferable solution for improving SOH monitoring across diverse applications.</div></div>","PeriodicalId":56142,"journal":{"name":"Sustainable Energy Grids & Networks","volume":"45 ","pages":"Article 102144"},"PeriodicalIF":5.6,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147395616","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}

While existing studies typically identify extremes based on meteorological thresholds, such as sustained low wind, low solar radiation, or extreme temperatures, these individual-variable extremes do not always cause the most severe power shortages. In contrast, moderately extreme events, namely compound weather conditions that are not individually severe in any single meteorological variable but jointly create unfavorable electricity supply-demand imbalances, can pose greater risks. To address this gap, this study aims to develop a consequence-based framework that directly identifies weather events causing the most severe power inadequacy risks, rather than relying solely on meteorological definitions of extremes. First, multi-decadal time series of wind, solar, and electricity demand are generated under various future capacity mixes with high VRE penetration. Then, a computationally efficient loss-of-load estimation method is proposed based on algebraic computations rather than mathematical optimization to identify weather events most likely to cause severe power shortfalls. Finally, power shortage risks are evaluated using power system economic dispatch simulations and compared across different types of extreme weather. Simulation results show that the proposed method can estimate loss-of-load with high accuracy and at a speed hundreds of times faster than dispatch optimization models. The case study reveals that identified events often involve moderately low VRE output and moderately high demand occurring simultaneously, resulting in severe shortages. At equal occurrence frequencies, these identified events pose several times the risk to power supply adequacy compared to individual-variable extremes and should be prioritized in power system planning.</div></div>","PeriodicalId":56142,"journal":{"name":"Sustainable Energy Grids & Networks","volume":"45 ","pages":"Article 102135"},"PeriodicalIF":5.6,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147395729","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}
