The system leverages LSTM autoencoders to detect deviations from normal operational patterns in order to identify anomalies induced by attacks or faults. Operational data for training and evaluation are derived from a Simulink-based model of an energy community. The results show that the autoencoder-based intrusion detection system achieves good detection performance across multiple attack scenarios, up to 0.9270 and 0.9735 in precision and recall respectively.

The research shows that: the value of data assets forms a self reinforcing cycle through the return reinvestment loop, and its scale expansion is regulated by the dynamic balance between the cost constraint and the value inhibition loop; The improvement of market risk perception, the robustness of the trading market, the increase of energy policy intensity and the weakening of peer competition can significantly improve the cumulative profits of enterprises; Adaptive investment strategy has more advantages than fixed investment strategy, but the timing of strategy transformation needs to be accurately controlled. The simulation results provide a basis for enterprises to optimize the data investment path.

This study analyzes three consecutive years (2017–2019) to assess the impact of climate variability on the energy trends of three PV technologies, fixed PV, Concentrated PV (CPV), and Dual Axis Tracking PV (DATPV), across six global cities. Sustainability scores were calculated using a GIS-based metric that captures energy consistency, intermonthly variability, and climatic adaptability, providing a technical evaluation of long-term system stability under varying weather conditions. The results reveal Cairo and Riyadh as top performers, achieving sustainability scores of 0.87 and 0.70, respectively, for fixed PV in 2019. In Madrid, DATPV systems excelled with sustainability scores reaching 0.39 in 2019, leveraging abundant solar resources. Meanwhile, Beijing’s fixed PV systems demonstrated exceptional stability, maintaining scores of 0.58 across all years, reflecting the region’s consistent solar conditions.

Despite increasing recognition of their importance, the concrete mechanisms and pathways through which digitalization drives energy conservation and emission reduction at the enterprise level remain insufficiently understood. Addressing this substantive gap, this study aims to systematically elucidate how digital technologies empower logistics enterprises to achieve low-carbon transformation. Using SF Holding—a leading digitalized logistics firm in China—as a representative case, we develop and empirically validate an integrated framework encompassing green innovation, energy substitution, and operational efficiency. Employing Grey Relational Analysis, we quantitatively investigate how six key factors—R&amp;D investment, cumulative granted patents, newly granted patents, new energy vehicle adoption, photovoltaic power generation, and enterprise digitalization degree—impact two core environmental performance indicators: greenhouse gas emission intensity and energy consumption intensity. The results demonstrate that cumulative technological capability and the degree of enterprise digitalization are especially influential in promoting emission reduction and energy efficiency. By clarifying the micro-level mechanisms—such as technological accumulation, clean energy integration, and operational optimization—this study advances theoretical understanding of digitalization-driven green transformation in logistics and offers actionable insights for both policymakers and industry practitioners seeking to foster low-carbon logistics through digital innovation.</p></div>","PeriodicalId":538,"journal":{"name":"Energy Informatics","volume":"8 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://energyinformatics.springeropen.com/counter/pdf/10.1186/s42162-025-00570-0","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144843218","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Uncertainty and several competing criteria on the demand and generation sides make multi-objective optimization difficult.

This study details a concept for optimizing the SPG’s operating cost and pollutant emissions using renewable electricity. Renewable energy sources, such as solar photovoltaic and wind power, are inherently unpredictable and subject to change. Uncertainty around renewable energy is handled by the suggested approach via the use of a probability density function (PDF). In order to address a multi-objective optimization (MOCO) issue, the model that was built relies on a MOCO method. A benchmark model for energy management and control is used to verify the performance of the suggested model, which is a multi-objective deep reinforcement learning (DRL) method. According to the results, MOCO reduces operating costs by 15% and environmental emissions by 8%.

For the actual operation of the decentralized resources in the alpine virtual power plant, we determined the power provided by the alpine virtual power plant to the electric power system as well as the adjustable power capacity and other scheduling parameters, and then designed the dispatch model objective with the decentralized resource power and scheduling parameters based on the imitator dynamic algorithm.

This approach enhances scheduling flexibility and resolves the grid-side secondary dispatch issue.

To coordinate multiple suppliers and demands in a local energy-system different control approaches can be used. This publication introduces a framework called MASSIVE that aims to coordinate multiple participants in a district energy-system. The energy-system is controlled in a distributed way by using a multiagent approach that is scheduled by a market-mechanism. This market-mechanism allows to coordinate many individual agents with only few restrictions by using pricing mechanisms. This offers an incentive for the agents to adapt their power consumption to best match the forecasted power supply. However, the agents are free to follow this incentive or ignore it depending on the value of the incentive. The individual agents are flexible in the internal approach to forecast power supply or demand, allowing easy development of agents using individual algorithms. The coordination takes place using a market-mechanism that is similar to the day-ahead market. It, however, is run multiple times a day to form a rolling horizon, making it less sensitive to forecasting errors. The market approach furthermore exhibits a nearly linear scalability with regard to the duration of the market clearing. On the used computer, the creation and solving of the linear optimization-problem is performed in less than one minute for approximately 1500 participating agents. Therefore, this approach is capable of real-time use and can be used in real-world applications.</p></div>","PeriodicalId":538,"journal":{"name":"Energy Informatics","volume":"8 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://energyinformatics.springeropen.com/counter/pdf/10.1186/s42162-025-00558-w","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145171076","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The presented framework utilizes openly available data and a hierarchical clustering approach to predict the likelihood of PV adoption for a company. Predicting PV adoption for companies allows identification of potential bottlenecks in the energy grid. As a recommendation system, it can be leveraged to promote PV systems more effectively, targeting areas with high adoption potential and optimizing grid infrastructure planning. In order to achieve that, openly available data sources have been acquired through web scraping. Company data then have been clustered using a hierarchical agglomerative approach.
