However, the bipolar coil has a complex structure and features a short energy transmission distance. Thus, unipolar coils rather than bipolar coils are adopted in the proposed multi-load IPT system in this paper. Compared to bipolar coils, unipolar coils cause cross-coupling between any two coils, not only those inside the same unit but also those among different units. To compensate for the cross-coupling inside the same unit, capacitor compensation based on the T-type decoupling principle is adopted. Then, to achieve better constant current characteristics, the cross-couplings between coils in constant voltage (CV) loops of different units are compensated according to their proportional current characteristics. Moreover, this paper analyzes the factors affecting the load current attenuation and provides guidance for achieving better constant current characteristics. Finally, a three-load IPT system is fabricated, and the capacitance compensation effect and constant current characteristics of the system are verified. The maximum reachable system efficiency is about 86.8% through measurement.","PeriodicalId":13337,"journal":{"name":"IEEE Transactions on Industry Applications","volume":"61 5","pages":"7684-7693"},"PeriodicalIF":4.5,"publicationDate":"2025-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144867712","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}

Consequently, the frequency security problem becomes increasingly prominent, which in turn hinders the effective accommodation of renewable energy. Hence, this paper proposes a novel frequency dynamics-constrained evaluation method of renewable energy hosting capacity (REHC) in power systems to provide insightful guidance for the healthy development of renewable energy. Firstly, we analyze the dynamic response mechanism in frequency regulation using various resources including CSG, energy storage and renewable energy. Subsequently, the frequency security algebraic constraints are derived based on the first-order swing equation considering the heterogeneity of multi-resource response characteristics and load-damping effect. Then, we formulate the REHC evaluation model with frequency security constraints considering both economic and technical aspects. To reduce the computation complexity and guarantee high-level accuracy, the piecewise McCormick envelop method is employed to relax frequency security constraints as linear equations, hence converting the original problem into a mixed-integer linear programming (MILP) problem. Eventually, the proposed REHC evaluation method is tested on the modified IEEE 39-bus system, and its effectiveness is verified by the numerical results.","PeriodicalId":13337,"journal":{"name":"IEEE Transactions on Industry Applications","volume":"61 5","pages":"7780-7789"},"PeriodicalIF":4.5,"publicationDate":"2025-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144868179","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}

This article proposes a new ZSC elimination strategy based on frequency-adaptive repetitive control (FARC) for OW machine drives to fully eliminate the ZSC during PF operation following inverter open circuit faults. In contrast to the traditional ZSC elimination methods, the proposed strategy can effectively eliminate the fundamental, triple, and additional frequency disturbances of the ZSC by only implementing ZSC closed-loop control. To this aim, a FARC based approach is proposed and designed to realize a zero steady-state tracking error of the ZSC loop by eliminating periodic disturbances that originate from both inverter and machine sides. Furthermore, a comprehensive analysis of the dead time effects on the ZSC during both healthy operation and PF operation is carried out. In addition, a decoupled space vector modulation technique is developed to produce the required zero-sequence voltage (ZSV) by unequally distributing the ZSC control signals of the legs of the two inverters within one duty cycle.

This paper presents a novel chattering-free fixed-time sliding mode power synchronization control (FSMPSC) approach specifically designed to enhance such black start capability of voltage-controlled (VC) inverters. The key aim of this controller is to enhance the robustness of the closed-loop system, facilitating the seamless integration of the inverter using grid-forming (GFM) control with the utility grid under various grid conditions. Remarkably, this integration is achieved without needing an additional synchronization unit, such as a phase-locked loop (PLL). The proposed controller significantly improves grid synchronization, allowing for a smooth transition of the inverter from off-grid to grid-connected modes while maintaining voltage source characteristics. The fixed-time stability analysis for the closed-loop system under the proposed controller is analytically derived by selecting an appropriate candidate Lyapunov function. This analysis facilitates the definition of an advanced form of sliding surface and control law, ensuring chattering minimization without compromising the fast response and robustness of the proposed controller.

A systematic design optimization methodology for magnetic couplers to achieve high power density and efficiency is lacking. In this paper, a model embedding electromagnetics and backpropagation neural network (BPNN) is developed to calculate two essential electromagnetic parameters: mutual inductance and power loss of magnetic couplers based on design parameters. Compared to analytical methods, the proposed model demonstrates superior accuracy and can model more complicated eddy current problems. The proposed model also features a simpler network structure and requires a smaller dataset (less than 50% ) than pure-data-driven approaches. Moreover, this methodology exhibits greater design flexibility over FEM with a significant reduction in optimization time by at least six orders of magnitude. The objective functions and constraints are established for multi-objective optimization. FEM and a 1.5 kW prototype verify the proposed method.

In this paper, a three-dimensional electromagnetic field model in the end region of a 300-MW DESG is established and the magnetic density and energy density in the end region of DESG are calculated and compared under the different operating conditions. The stator and rotor end leakage reactances are calculated by the energy method. Under the different operating conditions, the end leakage reactance of q-axis field winding varies by 11%, which is the largest compared to those of the d-axis field winding and stator winding. Based on that, the end leakage reactances are substituted into the two-dimensional field-circuit coupled time-stepping finite element model (FCCTSFEM), which is used to calculate the frequency characteristic of the DESG. The transient and sub-transient parameters of the DESG are calculated by combining the FCCTSFEM and the frequency domain method. The influence of the slot wedge material on the transient and sub-transient parameters are studied.

To feature the random characteristics of windings whilst minimizing complexity, a statistical winding model is established. This model uses only three parameters to control the generation of conductor arrangements with different degrees of mixing. These three parameters are calibrated by the measured data from a repeatedly inserted coil group, rather than a series of wound stator prototypes, thus significantly reducing the cost in a research and development (R&D) process. Thereafter, the statistical model with calibrated parameters is used to predict the AC copper loss of the full machine. A 48-slot 4-pole stator is used to illustrate and validate the method.
