This paper develops and applies a probabilistic method for assessing large-scale integration of PEVs in a real low voltage distribution system (DS) in Stockholm County, Sweden. The framework employs Monte Carlo simulations to capture uncertainties in driver behaviors, daily distances, charging start times, and vehicle allocation. Its key contributions are: (i) a replicable data-driven Monte Carlo framework that merges DS operator (DSO) load data with travel habit statistics, (ii) realistic charging-profile generation, (iii) demonstrate that adding price signals plus a network constraint almost doubles hosting capacity and cuts user costs, and (iv) a systematic comparison of uncontrolled versus controlled charging that clarifies technical-economic trade-offs.

Inefficiencies in energy utilization during the EV charging process occur due to power losses. To foster an energy-efficient system and support sustainable energy resource utilization, this paper introduces a consensus tracking control method for effective EVs charging coordination in a charging station. The primary aim is to reduce charging power losses and efficiently use the available power at the charging stations. The approach involves formulating power deviations of EVs and designing control gains. Graph theory is employed to create the communication network between EVs and the charging station. The consensus tracking algorithm facilitates the updating of local information, sharing of external information among neighboring EVs and the charging station, and ensures the convergence of the consensus goals. To demonstrate the proposed method, the consensus tracking controller is applied to an EV system based on both random parameters and commercial models’ parameters. The proposed method is evaluated for its fundamental performance using a system with three EVs, and for its scalability with a system comprising ten EVs, all within the Matlab/Simulink environment. Simulation results indicate that with commercial EV models, charging coordination is effectively managed while achieving the target EVs’ state of charge (SoC). In addition, the approach reduces power losses and maximizes the charging efficiency maintaining power losses in AC charging within 0.18 %–0.66 % and below 6.73 % in DC fast charging. Furthermore, the proposed consensus tracking method consistently converges regardless of varying EVs’ arrival and departure times.</div></div>","PeriodicalId":56142,"journal":{"name":"Sustainable Energy Grids & Networks","volume":"43 ","pages":"Article 101771"},"PeriodicalIF":4.8,"publicationDate":"2025-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144321126","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}

Therefore, this paper proposes an effective unsupervised data anomaly detection model based on a deep neural network autoencoder. This model does not require prior knowledge about the system and accurately identifies PV system anomalies with limited information. The proposed model only uses measured PV power production as input and does not need additional information on PV system parameters or measurement data. Additionally, we derived an optimal threshold to detect anomalies based on the mean and standard deviation of the reconstruction error, resulting in a significant improvement in the F1-score from 0.9123 with the traditional approach to 0.9993. Lastly, a novel locally adaptive mechanism based on Dynamic Time Warping (DTW) error analysis is proposed to effectively locate anomaly segments by considering the shape of anomalous parts within the input time series data. The proposed model is validated on a real PV power plant in Genoa, Italy.

Existing works fail to investigate concurrent cyberattacks and works that utilize time-frequency features for cyberattack detection only use the existing standard wavelet filters that have not been designed for cybersecurity applications. This work proposes a detection scheme for concurrent attacks using new wavelet filters with the Discrete Wavelet Transform (DWT) to better extract time-frequency features from substation automation system (SAS) data. A set of new wavelet filters are generated from parameterized equations. The wavelet filter that best suits SAS cyberattack detection is used to extract the salient features of cyberattacks using the DWT. Unlike existing detection approaches, the use of wavelet design allows the generation of new wavelet filters that better match the time-frequency features of SAS data. The proposed approach has been tested on a publicly available dataset as well as experimentally using OPAL-RT. The results demonstrate its effectiveness in detecting four popular cyberattack types as well as the challenging concurrent attacks, which involve two or more attacks occurring simultaneously. The use of wavelets not only enables the detection of the attacks but also their classification by type from power disturbances with an accuracy reaching 99.12 % on a synthetic dataset and 95.47 % on an experimental dataset. Furthermore, the results have shown that the use of the newly designed wavelets leads to an increase in the detection accuracy by 9.36 % and a significant reduction in the computational complexity of the feature extraction process by up to 99.16 % over the existing time-frequency transforms.</div></div>","PeriodicalId":56142,"journal":{"name":"Sustainable Energy Grids & Networks","volume":"43 ","pages":"Article 101768"},"PeriodicalIF":4.8,"publicationDate":"2025-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144271146","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}
