Firstly, a smart grid data transmission framework integrating digital twin technology is proposed. A digital twin mapping method based on time, data, and topology structure is used to realize the digital twin mapping at the device level of power grid. Through data synchronization and interaction between the physical power grid and the digital twin model, the operational efficiency and reliability of the power grid are improved. Then, the classical convolutional neural network and attention mechanism are used to comprehensively analyze the physical topology data in the smart grid energy acquisition system. The improved lightweight target detection model is combined to monitor the equipment status of the smart grid and extract key features. Simultaneously utilizing convolutional attention mechanism to dynamically adjust the feature weights of channels or spaces, completing the preprocessing of energy harvesting data. Finally, combined with energy harvesting and power grid switching system, the process of energy harvesting and power grid operation are optimized together. On the training and validation sets, when the channels exceeded 60, the proposed method achieved a system energy efficiency of 55% during operation. The system energy efficiency of the other three comparative algorithms was all less than 40%. In practical applications, as the energy transfer loss increased to 1.0, the system throughput increased to 50 bits. The electricity needs of different users were met, and the difference between power allocation and optimal power allocation was small, which was very reasonable. This proves that the research has effectively optimized the energy harvesting system in the smart grid, improving the efficiency and reliability of the system in practical applications of the smart grid. At the same time, in the increasingly severe energy problem, this system can further provide technical references for the utilization of renewable energy and help achieve the goal of sustainable energy.</p></div>","PeriodicalId":538,"journal":{"name":"Energy Informatics","volume":"7 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://energyinformatics.springeropen.com/counter/pdf/10.1186/s42162-024-00425-0","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142672702","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 impact of uncertainty in renewable energy output on system flexibility was evaluated through system flexibility analysis and scenario construction techniques, and effective flexibility improvement strategies were proposed in combination with optimized scheduling design. The research results show that under high penetration of renewable energy, there is an imbalance between the supply and demand of flexibility in the power system. When the proportion of renewable energy installed capacity reaches 40%, the system flexibility gap reaches 10%. A comprehensive optimization strategy has been proposed to address this issue, including constructing energy storage facilities, demand side response, and virtual power plants.

Hence, we present and evaluate a novel method for distribution grid monitoring. This method uses smart plugs as measuring devices and a feature propagation algorithm to generate pseudo-measurements for each grid node. The feature propagation algorithm exploits the homophily of buses in the distribution grid and diffuses known voltage values throughout the grid. This novel approach to deriving pseudo-measurement values is evaluated using a simulation of SimBench benchmark grids and the IEEE 37 bus system. In comparison to the established GINN algorithm, the presented approach generates more accurate voltage pseudo-measurements with less computational effort.

Nevertheless, the extant research on charge prediction predominantly employs a single model or an enhanced single model. However, these approaches do not fully account for the intricacies and variability of the actual driving road conditions of the vehicle. Furthermore, the prediction accuracy of the charge state in the latter phase of discharge remains suboptimal. To further improve the accuracy of predicting the state of charge, the study utilizes actual operating data of new energy vehicles and combines two proposed algorithms to build a first layer learner of a fusion prediction model. The second layer learner integrates various prediction results. The fusion model can enhance its adaptability to complex data structures by combining the gradient boosting ability of XGBoost algorithm and the diversity of Random Forest when dealing with nonlinear problems. This fusion method modifies the input features of the second layer of the fusion model, enhances the complexity of the second layer learner, effectively circumvents overfitting, and exhibits reduced error rates relative to traditional single-chip prediction models. As a result, the performance of the prediction model is significantly enhanced. The tests showed that when using the fusion model for state of charge prediction, the prediction accuracy could reach 97.6%, and the prediction accuracy was higher than the other four comparison models. When the car was driving in a 25 ℃ highway environment, the root mean square error of the fusion model was 1.3%, and the average absolute error was 1.5%. In urban road environments, the root mean square error of the fusion model was 1.5%, and the average absolute error was 1%. The experiment demonstrates that the proposed fusion prediction model can accurately predict the charging status, thereby enabling the battery to be fully utilized while simultaneously reducing energy consumption. In comparison to the traditional single model or enhanced single model, the proposed fusion model has demonstrated a notable enhancement in both prediction accuracy and computational efficiency.</p></div>","PeriodicalId":538,"journal":{"name":"Energy Informatics","volume":"7 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1186/s42162-024-00424-1.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142598873","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}
