An unavoidable issue is that battery performance will continue to degrade as materials age and cycle time increases. Accurately predicting the Remaining useful life (RUL) of LIBs is an important prerequisite to ensure the safe driving of EVs. However, the actual battery management system may encounter sensor or communication system failures, resulting in missing or incomplete data, which will result in inaccurate battery RUL predictions. This article presents a novel method based on hybridization of Generative adversarial imputation nets (GAIN) and Stacked denoised autoencoder with Kriging (SDAE-Kriging) for the prediction of RUL of LIBs in scenarios of missing and incomplete data. In the proposed method, the GAIN is leveraged to realize the filling of missing and incomplete data. The SDAE-Kriging is used to predict the RUL of LIBs with filled data. Different missing rates (10%, 20%, 30%, and 40% ) are investigated to establish RUL prediction models. It is manifested that the GAIN has better data filling results on two datasets. After completing the data filling, the results show that SDAE-Kriging has high prediction accuracy (RMSE is less than 0.1) for both datasets, even when the missing rate is 40% . The proposed scheme can provide an effective solution for the RUL prediction of LIBs in the scenario of missing and incomplete data in practical industrial applications.","PeriodicalId":13337,"journal":{"name":"IEEE Transactions on Industry Applications","volume":"61 3","pages":"4590-4599"},"PeriodicalIF":4.2,"publicationDate":"2025-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144100082","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}

The proposed method formulates a stochastic unit commitment (SUC) problem with explicit modeling of predicted risks caused by extreme wind. Contingency scenarios are selected considering not only the impact of an element failure on the entire network but also how close the electrical distance between element failures on the network.

Those stresses may lead to progressive degradation of the motor components until a failure appears. However, it is to be noted that the inherent manufacturing tolerances have a strong role to play in the ageing mechanism because the various stresses will have a stronger impact on them. Stator faults are among the most serious faults in all electric motors due to their fast evolution to a catastrophic breakdown. Stator faults are linked with the degradation and failure of the insulation system. This paper will aim to provide a detailed equivalent circuit of a permanent magnet motor's stator poles with mounted armature coils for impedance spectroscopy purposes. The experimentally derived model is a sensitive map to manufacturing weaknesses in the insulating materials and can be used for identifying different defects, as well as their form and location, thus improving the quality inspection procedure before the assembly of the motor. This procedure will exclude poles with weak insulation and therefore significantly increase the longevity and reliability of the motors.","PeriodicalId":13337,"journal":{"name":"IEEE Transactions on Industry Applications","volume":"61 4","pages":"6347-6356"},"PeriodicalIF":4.2,"publicationDate":"2025-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144550742","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}

Hence, the DER is expected to exhibit Low Voltage Ride-Through (LVRT) capabilities with reactive power support during a fault, as per IEEE 1547. Determining the amount of reactive power during unsymmetrical faults in the distribution system is challenging as it requires unbalanced reactive power support depending on the type of fault. Proper reactive power support can also help minimize the voltage rise in the healthy phases. This paper proposes a novel Per-Phase Reactive Power Control (PRPC) strategy that enables DER to inject reactive power in faulted phases and absorb reactive power in healthy phases during an unbalanced fault. This strategy helps boost voltages on faulted phases while reducing the voltage rise on the healthy phases. Test results on a sample distribution system are given to illustrate the advantages of this proposed scheme. In addition to validating the analytical framework with simulations, the effectiveness of the proposed PRPC strategy is also further validated through a real-time simulation performed on NovaCor Real-Time Digital Simulator (RTDS).","PeriodicalId":13337,"journal":{"name":"IEEE Transactions on Industry Applications","volume":"61 4","pages":"5868-5879"},"PeriodicalIF":4.2,"publicationDate":"2025-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144550463","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}

In this paper, the urban power system guides FCEVs to orderly charge through appropriate pricing strategies. To do this, a novel demand response (DR) model is established to simulate the spatial flexibility of FCEVs under different charging prices. In order to realistically reflect the power deviations when FCEVs participate in DR, a hybrid exogenous and endogenous uncertainty set is proposed to capture the effects of environmental and user psychological factors. Furthermore, a two-stage robust model is developed to relieve congestion. Specifically, a bi-level model is employed to optimize locational marginal electricity prices, aiming to achieve collaboration between transmission and distribution networks in the first stage. The two-stage robust model is then transformed into a tractable form and solved using the modified parametric column-and-constraint generation (CCG) algorithm proposed in this paper.

In contrast to conventional active methods, which intentionally disturb the system, this method is completely passive, ensuring no adverse effects on power quality, stability, or reliability. This method focuses on the phase angle between two specific components, the superimposed component of zero sequence current (<inline-formula><tex-math>$Delta {{I}_0}$</tex-math></inline-formula>) and voltage (<inline-formula><tex-math>$Delta {{V}_0}$</tex-math></inline-formula>). By continuously monitoring the cumulative sum (CumSum) of this phase angle at the DG connection point, the system can identify islanding events. The calculated values of <inline-formula><tex-math>$Delta {{I}_0}$</tex-math></inline-formula> and <inline-formula><tex-math>$Delta {{V}_0}$</tex-math></inline-formula> exhibit inconsistencies in their magnitudes and variations due to real power imbalance, making them unsuitable for islanding detection. A key benefit of this approach is its capability to nearly eliminate the issue of large non-detection zones (NDZ), a common problem with many passive islanding detection methods. As a result, the technique can identify islanding events more reliably under a wide range of operating conditions. Simulation studies were conducted using PSCAD/EMTDC software to showcase the effectiveness of the proposed method. Testing across various system configurations verified its capability to minimize the NDZ and detect islanding events in under 10 milliseconds, far quicker than the usual response time of reclosers, which is approximately 150 ms. The proposed approach was further tested and validated using the RTDS simulator in conjunction with the dSPACE (DSP-1104) controller.","PeriodicalId":13337,"journal":{"name":"IEEE Transactions on Industry Applications","volume":"61 4","pages":"5797-5807"},"PeriodicalIF":4.2,"publicationDate":"2025-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144550509","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}

Especially, the higher pole ratio (PR), i.e., the ratio of PM pole-pair to armature pole-pair, the severer torque drop of SAPMVM. In this paper, a novel SAPMVM is proposed, where the magnets bridge is introduced, which can effectively restrict the flux barrier effect. As a result, both the working flux harmonics and torque density of SAPMVM are enhanced. To analyze the operating principle of proposed SAPMVM with magnets bridge, an equivalent magnet circuit model is established. Moreover, the electromagnetic performances of the proposed SAPMVM are compared with regular SAPMVM by FEA, where the torque of proposed SAPMVM has increased by 43.3% and 175.6% under rated-load when the PR is selected as 5 and 11.","PeriodicalId":13337,"journal":{"name":"IEEE Transactions on Industry Applications","volume":"61 4","pages":"6336-6346"},"PeriodicalIF":4.2,"publicationDate":"2025-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144550707","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}
