Experimental comparisons demonstrate that the blockchain platform ​reduces transaction costs by 30%, shortens settlement time by 75%, and significantly enhances market liquidity and transparency versus traditional modes.

{"title":"Fault location and isolation technology for power grid automation based on intelligent algorithms","authors":"Qi Guo,&nbsp;Fuhe Wang,&nbsp;Suxia Cheng,&nbsp;Ke Wang,&nbsp;Yifan Zhang","doi":"10.1186/s42162-025-00522-8","DOIUrl":"10.1186/s42162-025-00522-8","url":null,"abstract":"<div><h3>Background</h3><p>Power grid automation is critical for maintaining the stability and reliability of electrical grids. A major challenge in power grid management is identifying and isolating faults quickly and accurately to avoid widespread disruptions. Traditional fault detection and isolation methods rely on rule-based diagnostics, which frequently struggle for speed, precision, and adaptability to changing fault conditions. As power grids become more complex, intelligent algorithms are critical for improving the efficiency of fault localization and isolation.</p><h3>Problem statement</h3><p>Conventional fault management methods, like rule-based and heuristic methods, have limitations in both accuracy and real-time adaptability. To address these issues, this study proposes and assesses two intelligent algorithms: the Fault Localization Algorithm (FLA) and the Fault Isolation Algorithm (FIA). Unlike conventional methods, FLA incorporates machine learning methods to improve fault detection, whereas FIA provides an optimized isolation strategy, decreasing operational delays and reducing power disruption.</p><h3>Methodology</h3><p>The FLA algorithm uses a Support Vector Machine (SVM) classifier to predict fault locations based on key variables like voltage, current, frequency, line impedance, and meteorological conditions. The FIA algorithm then uses the FLA output to evaluate fault severity and select the best fault isolation strategy. This approach combines an SVM-based fault localization algorithm with a decision-tree-based fault isolation strategy to guarantee quick and accurate fault identification, reducing system downtime and enhancing fault resolution efficiency. The proposed system is validated with the PowerGrid Fault Localization Dataset (PGFLD), which contains practical power grid fault data.</p><h3>Results</h3><p>Experimental findings show that the proposed FLA algorithm achieves 92% accuracy, outperforming traditional techniques like Decision Tree (85%), KNN (82%), and Logistic Regression (78%). Furthermore, FIA achieves 95% accuracy, outperforming current rule-based (89%) and heuristic (85%) methods. These findings show a significant enhancement in fault detection accuracy and isolation effectiveness, which reduces false positives and improves power grid resilience.</p><h3>Conclusion</h3><p>This study provides an innovative method of power grid fault management that employs intelligent algorithms for fault localization and isolation. The use of SVM for fault localization and decision-tree-based fault isolation improves fault detection accuracy while reducing operational delays. The proposed methods improve grid resilience and offer actionable isolation tactics, making them extremely effective for contemporary power grid automation.</p></div>","PeriodicalId":538,"journal":{"name":"Energy Informatics","volume":"8 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://energyinformatics.springeropen.com/counter/pdf/10.1186/s42162-025-00522-8","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145141892","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}

In this study, we used Monte Carlo (MC) simulations—trained on each leaf that generated by the regression tree (RT) algorithm—to predict the electricity consumption of Widya Dharma University Pontianak (UWDP)’s campus building. Unlike traditional approaches that rely on the mean of samples within a leaf, our method incorporates their likelihood. Since RT algorithms are prone to overfitting, training each leaf individually is expected to mitigate this issue. The data were collected by measuring hourly electricity consumption on one floor of the UWDP campus building over several months.

However, the charging demand of electric vehicles brings new challenges to regional power grids, especially those that rely on clean energy, due to its uncertainty and randomness. This study examines the impact of EV charging demand on the control efficiency of clean energy-based regional power grids. Using real grid data and time-series simulation, we develop a dispatch optimization framework incorporating a master-slave game model based on wind power output distribution. We simulate EV charging patterns, renewable fluctuations, and uncertainties in user behavior and station availability. The results show that unmanaged charging increases peak load by up to 20%, while optimized strategies like Time-of-Use (TOU) pricing, Direct Load Control (DLC), and Vehicle-to-Grid (V2G) reduce the peak-valley gap by 15%, improve renewable energy consumption by 12%, and lower curtailment. These findings offer valuable insights for EV integration and clean energy planning in regional grids. The results show that at a 30% EV penetration rate, the peak charging demand may lead to a 20% increase in the regional grid load, and by optimizing the charging time, the peak-valley load difference can be reduced by 15%. In addition, a reasonable charging strategy can help improve the utilization rate of clean energy, maximize the consumption of wind power and photovoltaic power generation, and reduce dependence on fossil fuel power generation.</p></div>","PeriodicalId":538,"journal":{"name":"Energy Informatics","volume":"8 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://energyinformatics.springeropen.com/counter/pdf/10.1186/s42162-025-00538-0","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145143195","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}
