These factors contribute to the presence of significant low and high frequency harmonics component in the stator current, which in turn deteriorates the accuracy of the speed and position estimation. These harmonics not only affect the performance of the SMO but also hinder the overall control system’s dynamic response. To address these challenges, this paper presents a high-precision harmonics suppression scheme based on a full-frequency domain approach. The proposed solution involves a series of adaptive comb filters (SACF) to effectively suppress low-frequency harmonics, thereby eliminating phase delays and improving BEMF estimation. Additionally, an LC filter combined with a frequency adaptive notch filter (FANF) is employed to mitigate high-frequency harmonics, which are particularly problematic due to their interaction with the sampling process. Experimental results validate the practicality and effectiveness of this proposed strategy. The proposed method significantly reduces harmonic components in the motor, leading to notable improvements in the dynamic performance of the control system and enhanced accuracy of speed and position estimation.","PeriodicalId":13337,"journal":{"name":"IEEE Transactions on Industry Applications","volume":"61 6","pages":"9326-9336"},"PeriodicalIF":4.5,"publicationDate":"2025-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145100433","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}

With the object to maintain the frequency and voltage stability during the grid-connected operation, GSFs, however, has raised great concerns on the effectiveness degradation of islanding prevention. Focusing on it, this paper evaluates the performance of the widely used islanding detection method, Slip-Mode Frequency Shift (SMS) operating together with GSFs. First, a small-signal model for this control combination is firstly derived, facilitating the investigation of interaction mechanism between GSFs and SMS. Accordingly, the optimal range of SMS coefficient is identified to guarantee both a successful islanding detection when an island forms and a stable operation during the grid-connected condition. It is observed that several key parameters, especially the slope and the open-loop response time of GSFs, as well as the SMS coefficient, jointly dominate the effectiveness of the islanding detection and should be deliberately designed. Finally, extensive simulations and controller hardware-in-the-loop (HIL) tests are performed to validate the above analysis.","PeriodicalId":13337,"journal":{"name":"IEEE Transactions on Industry Applications","volume":"61 6","pages":"9602-9614"},"PeriodicalIF":4.5,"publicationDate":"2025-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145100475","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, an analytical model is proposed in this paper to predict the airgap fields of MCSRMs, in which the tangential field and nonzero time-dependent magnetomotive force (MMF) are all accounted for. The model distinguishes the effect of armature winding, as well as single- and bilateral-magnetic-salient structure, on airgap field harmonics, facilitating root cause analysis of these harmonics. Furthermore, the average torque, torque ripple, radial and tangential electromagnetic force density of MCSRMs under non-saturation condition can be quickly predicted.

This article presents a pricing algorithm to charge consumers and distributed energy resources (DERs) based on their impact on the distribution network. This method utilizes a sensitivity approach to calculate the deviation in system annual chargeable cost based on the incremental change in a) the real and reactive power flow of the facilities, b) the MW-Miles and MVAr-Miles flow of the system, and c) the power factor of the system. This reflects the combined effect of all these parameters and either charges or incentivizes the consumers based on the amount of real and reactive power they are consuming, the distance used to support customers’ real and reactive power injection/withdrawal, the capacity of DN assets being utilized while power is being delivered to consumers and influence on system power factor.The main advantage of the proposed approach is that it is not dependent on the tracing algorithm to detect the power flow paths, hence capable of computing DUoN for decent-sized DNs embedded with DERs, where the contribution of power to the consumers by the DERs or from the grid is difficult to determine or trace. Additionally, due to the appraising and penalizing characteristics of the proposed DUoN charging mechanism, the proposed pricing algorithm may encourage users to act based on local economic signals. This algorithm has been tested on a modified Western network, the IEEE-15 bus network, the IEEE-69 bus network, and the IEEE-123 bus network.","PeriodicalId":13337,"journal":{"name":"IEEE Transactions on Industry Applications","volume":"61 6","pages":"8688-8702"},"PeriodicalIF":4.5,"publicationDate":"2025-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145090068","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}

A novel composite control strategy based on high-order sliding mode control with extended state observer (ESO-HOSMC) is proposed to address the critical challenge of DC-link voltage fluctuations in SMES-DVR. By synergizing extended state observer-based disturbance estimation with super-twisting high-order sliding mode control, ESO-HOSMC control method effectively balances the contradiction between rapid response and operational stability during the charging and discharging process of the superconducting magnet, while reducing total harmonic distortion of sensitive load voltage. Theoretical analysis containing controller modeling, designing and stability analysis has been demonstrated. In addition, performances among the ESO-HOSMC control, model predictive control (MPC) and conventional PI control of SMES-DVR have been compared under different voltage sag or swell scenarios.

Therefore, this paper proposes a payment and incentive allocation method for customer directrix load (CDL)-based DR mechanism. First, we conduct a comprehensive survey on the fund flows in existing DR programs and summarize the reasons why they fail to meet CCP requirements. Subsequently, a CCP-based fund flow model in DR programs is proposed. To rapidly and transparently quantify the payment ratios, the concept of effective energy shift is proposed to assess the marginal impact of the potential causers on flexibility demand. Furthermore, a DR incentive allocation method is proposed, where different types of DR customers receive the incentive in proportion to the CDL similarity index without bias. Meanwhile, the scale of DR fund pools is determined through a total social welfare maximization optimal model, which can be swiftly solved by a tailored Bayesian optimization algorithm.

The discharge ratio is commonly set to an arbitrary value such as 50<inline-formula><tex-math>$%$</tex-math></inline-formula>, but it has been found that an optimal choice of discharge ratio exists.

Traditional methods fail to separate the harmonics that affect torque density and pulsating torque, leading to a degradation of torque density when reducing pulsating torque. Therefore, to maintain torque density and simultaneously reduce pulsating torque, this paper proposes a novel FRM configuration incorporating shape designs for the rotor and permanent magnets (PMs). First, the key generation mechanisms of cogging torque, average torque, and torque ripple are thoroughly examined, with analytical expressions derived to classify the torque contributions of all air-gap magnetic field harmonics into negative-effect and positive-effect components. Further, the rotor and PM shapes are designed to enhance the positive-effect components and reduce the negative-effect ones of the air-gap permeance and magnetomotive force (MMF). The impacts of geometric parameters are evaluated by using a sensitivity-based hierarchical optimization approach. Then, the proposed FRM is comprehensively compared with a conventional FRM in terms of back-electromotive force (EMF), cogging torque, average torque, torque ripple, efficiency, etc. The results indicate that the proposed machine configuration achieves reductions in cogging torque and torque ripple by 90% and 86.8%, respectively, while maintaining consistent average torque.

In terms of the control and coordination of hosted DGs, the enhanced stability and fast dynamics of DC microgrids are required. To achieve these objectives, this paper proposes a comprehensive strategy that meticulously accounts for the impacts of transmission line impedances and constant power loads (CPLs). The strategy is architected with a dual-layer control approach: a stability enhancement controller is embedded within the primary control layer, while a novel distributed fixed-time controller is deployed in the secondary control layer, ensuring a robust and fast system performance. Specifically, for the primary control layer, the maximum tolerable CPL is firstly calculated using the reduced-order model and the impedance ratio criterion, contributing to more accurate and less conservative results. Additionally, a stability enhancement controller is designed to reshape the system's equivalent output impedance, improving both steady-state and transient stability of the DC microgrid and enabling the accommodation of larger CPLs. For the secondary control layer, a novel fixed-time secondary control scheme is put forward to achieve a concurrent DC bus voltage regulation and current sharing among DGs within a fixed time. Importantly, this method requires the transmission of only one variable to neighboring DGs, significantly decreasing communication traffic compared to the existing latest methods. The stability of the proposed scheme is theoretically proved through Lyapunov-based analysis. Case study results are presented to demonstrate the efficacy of the proposed strategy.","PeriodicalId":13337,"journal":{"name":"IEEE Transactions on Industry Applications","volume":"61 5","pages":"8064-8079"},"PeriodicalIF":4.5,"publicationDate":"2025-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144867711","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}
