This article presents a comprehensive comparison of high-speed synchronous machines, encompassing synchronous reluctance, its permanent magnet variant, and surface permanent magnet synchronous motors. The evaluation of their maximum performance capabilities employs a hybrid analytical-finite element design procedure able to address electromagnetic, thermal, and structural requirements simultaneously. Indeed, the adopted design methodology takes into account all the machines nonlinearities, while also including the limitations introduced by the iron ribs of the reluctance machine, retaining sleeve of the surface permanent magnet machine and increasing iron losses. The aim of the outlined design exercise is to evaluate the effect of different design specifications on the maximum achievable performance of the three machine topologies. A wide range of maximum design speeds, airgap thicknesses, and cooling system capabilities has been assessed showing when and why one motor type outperforms the others. The cooling system capability increment required by the reluctance-based machines to achieve the performance of the surface permanent magnet one has been systematically quantified. The design assumptions have been verified by a thermal analysis supporting the final machine selection. Three different machines designed with a maximum speed of 80 kr/min have been prototyped and tested on an instrumented test rig, validating all the design considerations.

Na-ion batteries are growing interest due to their sustainability and low cost. A wide implementation in stationary applications, but also for short range transportation, is envisaged. This is further supported by the recent progress on Na-ion cells with increased energy density. To this regards, the development of procedures for real-time assessment of batteries state of health is of crucial relevance. The present paper provides an innovative procedure to assess sodium-ion battery capacity fading based on the application of discrete wavelet transform to voltage signals, acquired once a certain load pattern is applied at the battery terminals. The procedure development is provided through Na-ion cell aging test. During all the test battery capacity measurements are carried out. Root mean square error (RMSE) between assessed and measured values equals 1.18%. Moreover, during the aging test significant differences between performance evolution of Na-ion and NCR Li-ion cells are highlighted and discussed.

Sliding mode controllers (SMCs) are commonly used in permanent-magnet synchronous machines (PMSMs) for current control due to their robustness and simplicity. However, high gains used in traditional discontinuous SMC implementations can induce chattering. To address this, disturbance observers are employed to maintain robustness without resorting to high gains. This article introduces a novel continuous asymptotic SMC method for PMSM currents that avoids the need for disturbance observers, resulting in reduced complexity and tuning efforts. The control laws of the two $dq$-axes currents are obtained through the sensitivity of the tracking errors with respect to the controller outputs. The robustness and convergence properties of the proposed control laws are theoretically studied using the Lyapunov approach. Numerical simulations are used to evaluate the performance and robustness of the proposed controller, followed by experiments to compare it to a discontinuous terminal SMC with and without a disturbance observer. The results clearly demonstrate the superiority of the proposed controller that ensures fast convergence, low chattering, and high robustness to parameter variations without requiring the design of additional disturbance observers.

Electric vehicles (EVs) are the best solution to tackle the critical challenge of reducing carbon emissions in the transportation sector. However, the widespread adoption of EVs relies on advancing fast-charging infrastructure technology. This includes overcoming challenges related to operating under disturbed conditions, which can impact the stability of the internal control loop. This article presents a method for robustly tuning a generalized predictive control (GPC) for an EV charger grid converter. This approach aims to enhance its performance in the face of disturbances in the grid voltage and internal filter parameters. One significant scientific gap in applying GPC in grid-tied converters concerns systematic tuning. This article addresses this gap by explicitly analyzing the impact of tuning on the stability and robustness of the GPC controller. The concept of robust stability margin, derived from singular value decomposition, is used for this purpose. Experimental results obtained from an EV charger prototype validated the tuning proposal aimed at maximizing the robustness and performance of the grid converter. The tests with different internal filters guaranteed a performance level within the defined error band. Furthermore, experimental tests have shown that the proposed controller is more robust than conventional MPC.

Icing is one of the most serious threats to power grid security in cold seasons. This article studies a problem of cooperatively scheduling inspection unmanned aerial vehicles (UAVs) and deicing UAVs for power grid deicing, the aim of which is to minimize the total expected loss of outages and collapses caused by the icing disaster. Uncertain outage risk, collapse risk, and deicing workload of each power line are modeled as fuzzy values predicted by fuzzy deep learning models, and we transform the fuzzy optimization problem into a crisp optimization problem based on fuzzy arithmetics and uncertain theory. We propose an evolutionary algorithm, which combines global search without individual interaction and adaptive local search that uses a fuzzy inference system to determine the operator to be applied on each solution. The algorithm is fully parallelizable and therefore can solve the problem very efficiently based on GPU parallel acceleration. Computational results on real-world problem instances validate the performance of the proposed method compared to the state of the arts.

Detecting series ac arc faults in diverse residential loads is challenging due to variations in load characteristics and noise. While traditional artificial intelligence-based algorithms can be effective, they often involve high computational complexity, limiting their real-time implementation on resource-constrained edge devices. This article introduces lightweight arc fault detection network (LArcNet), a novel, lightweight, and rapid-response algorithm for series ac arc fault detection. LArcNet combines a teacher–student knowledge distillation approach with an efficient convolutional neural network architecture to achieve high accuracy with minimal computational demand. This streamlined yet robust design makes LArcNet ideally suited for resource-constrained embedded systems, achieving an arc fault detection accuracy of 99.31%. The model is optimized and converted into TensorFlow Lite format to reduce size and latency, enabling deployment on low-power embedded devices such as the Raspberry Pi and the STM32 microcontrollers. Test results demonstrate LArcNet's inference times of just 0.20 ms on the Raspberry Pi 4B and 3 ms on the STM32H743ZI2, surpassing other leading models in operational speed while maintaining competitive accuracy in arc fault detection.

Among the converters currently employed for ac–dc conversion, diode rectifiers (DRs) and voltage source rectifiers are the most prevalent due to their accessibility, cost-effectiveness, and efficiency. However, current source rectifiers (CSRs) present several advantages, such as short-circuit protection, step-down capabilities, minimal output current ripple, and the elimination of dc bus capacitors. These features can lead to a reduction in overall size and an enhancement in power quality, although CSRs are often associated with higher conversion losses. Recent advancements in applications that can leverage the benefits of CSRs, along with the development of new devices to improve their efficiency, have produced renewed interest in this configuration. This article aims to review the design parameters of CSR components, modulation schemes, and control strategies, while also conducting a loss analysis using both established literature methods and innovative approaches developed by the authors. In addition, a comparison with other topologies is presented, illustrating that in certain applications and conditions, CSRs can be a compelling choice. Thus, rather than focusing on a specific aspect of CSRs, this article provides a comprehensive overview of the topic, offering practical insights for engineers.

Due to the rapid development of power electronics and energy storage technologies, the trend toward electrified railway systems with onboard energy storage systems (OESS) is being followed by main train manufactures. In such systems, the control of the dc-link can be critical for stability and optimal power sharing between different energy sources. This paper presents a dc-link control strategy intended for OESS-based traction chains. A distinguishing characteristic of the proposed method is its ability to smoothly share the power demand among the available power sources, including the kinetic energy of the train, based on predefined priority levels. The control smoothly reacts to changes in the power limits, including no power, of the available energy sources, without modifying the control structure and with negligible variations of dc-link voltage. Simulation results are provided using a real train model with an onboard battery system. Finally, the proposed control is validated on a hardware prototype.
