To address this challenge, we propose MDCTL-MCI, a missingness-aware forecasting framework that jointly leverages signal decomposition, multi-scale covariate interaction, and multi-domain collaborative transfer learning. First, multivariate singular spectrum analysis (MSSA) denoises and reconstructs incomplete time series, enhancing underlying temporal structures without explicit imputation. Next, a lightweight multiscale covariate interaction (MCI) module models interactions among reconstructed PV power, global horizontal irradiance, direct normal irradiance, and total solar irradiance at varying temporal resolutions, capturing both local fluctuations and global trends. Finally, a multi-source domain collaborative transfer learning strategy aggregates knowledge from multiple PV sites to form a global model, which is then fine-tuned on a small set of high-quality, MSSA-processed samples at each site. By freezing all but the output layer during fine-tuning, MDCTL-MCI adapts efficiently to local data heterogeneity. Extensive experiments on four Chinese PV installations reveal that, compared to baseline methods, the proposed method improves average accuracy by 10.5 % under complete data conditions and by 15.3 % under various missing data scenarios.</div></div>","PeriodicalId":246,"journal":{"name":"Applied Energy","volume":"401 ","pages":"Article 126771"},"PeriodicalIF":11.0,"publicationDate":"2025-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145118442","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While the restoration and repair of individual systems are documented in the literature, their coordination in CPW recovery is rarely focused on. This work proposes a temporal-spatial coordinative method to improve CPW resilience by co-optimizing the recovery process comprising repair crew dispatch and adaptive service restoration. Firstly, a CPW model is developed based on physical mechanisms and component-level interdependencies. The model includes typical post-disruption features, like imbalanced three-phase power flows and pipe breakages. Secondly, a coordinated framework is designed for recovering damaged CPW, considering faulted components, available crew, and resources. The framework hierarchically comprises two stages. The first stage conducts absorption via components' operation and network topology adjustment. The second stage organizes the grouping and routing of repair crews, with further adjustments of absorption to exploit newly repaired components. In addition, multi-terminal soft open points (MT-SOPs) are applied to facilitate flexible power flow control and network reconfiguration of imbalanced power networks to augment the repair process. We also modeled the diverse correlated uncertainties and applied a sample-based optimization approach for timely and robust solutions. The proposed method is validated on a modified 36-node/33-bus CPW system, demonstrating a 32.51 % reduction in unsupplied loads compared to separate recovery. Additionally, incorporating MT-SOPs further reduces unsupplied loads by 16.94 % compared to traditional tie-lines. A large-scale evaluation on a 308-node/150-bus synthetic model further confirms the effectiveness of our framework in real-world CPW systems.</div></div>","PeriodicalId":246,"journal":{"name":"Applied Energy","volume":"401 ","pages":"Article 126781"},"PeriodicalIF":11.0,"publicationDate":"2025-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145118319","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These physics-informed parameters, along with terminal voltage, current, and temperature measurements, are used as inputs to a dual-stage network comprising an aging model and a temperature compensation model for SOC estimation. A Kalman filter is then employed to refine the estimated SOC by leveraging the recursive characteristics of SOC dynamics. The PIDN method is validated under various operating conditions, including different aging levels, temperatures, and dynamic current profiles, using the urban dynamometer driving schedule and US06 tests. The results demonstrate that the PIDN method achieves reliable estimation accuracy, with a root mean square error below 1.76 % and a maximum absolute error below 4.55 % under previously untrained conditions.

There is a growing need for integrated approaches to capture the complex dynamics within the WEC nexus and evaluate the integrated risks in future scenarios, thereby synergistically mitigating the pressures on the WEC nexus. This study selected Beijing, heavily reliant on external resources and in urgent need of carbon emission reductions, as a case study. Incorporating socioeconomic impacts, a water–energy–carbon system dynamics model was constructed to simulate the supply and demand of resources and the corresponding carbon emissions. The water, energy, and carbon pressure indices were also predicted to quantify the pressure on each subsystem. Three-dimensional copula functions were subsequently established for integrated risk evaluation. The results reveal that the three pressure indices will exhibit an increasing trend without policy intervention in 2022–2035. With respect to different scenarios, improving utilization efficiency and augmenting the external supply can effectively alleviate water and energy shortages, whereas adjusting the energy consumption structure contributes to reducing carbon emissions. Compared with the baseline scenario, the combined scenario of all the policies performs best among the multiple scenarios, where the risks of water scarcity, energy insufficiency, and excessive carbon emissions decrease significantly to 0.19, 0.06, and 0.05, respectively, and the integrated risk experiences a substantial reduction of 71 %.

Existing models tend to overestimate theoretical optical efficiency limits by neglecting significant shadowing and blocking losses, while most optimization methods lack universal guidance for heliostat field design. This study proposes a pattern-free layout model to estimate optical efficiency limits more realistically. By incorporating a mechanism that screens shadowing and blocking losses under ideal distance constraints, the model corrects these overestimations. Additionally, the high-freedom layout strategy, without preset symmetry, overcomes traditional performance limitations. Compared to the existing model, the proposed model reduces the overestimation of optical efficiency limits by 8.92 % for large heliostat field. The study reveals that macro parameters, such as tower height and heliostat total area, have a dominant effect on efficiency limits, while micro parameters have a negligible impact. Through response surface methodology, a second-order regression model was developed to quantify the interactions among macro parameters, achieving a high prediction accuracy (<em>R</em><sup><em>2</em></sup> = 0.888). The study also investigates the optimal levelized cost of optical parameter combinations and heliostat field layouts at 30°N, with the results showing that the parameter combinations are significantly lower than those for the optimal optical efficiency limit estimation. The optimal layouts exhibit a consistent umbrella-like shape, emphasizing the importance of layout in field performance.

Accurate modeling of this interaction is essential for reliable simulation and optimization.

The realistic representation of the thermal-hydraulic interactions between soil and pipes, as well as the heat flow within the network, confirms the accuracy of the model and its applicability for the simulation of 5GDHC systems.
