“…Among these, homopolar inductor motors (HIMs) have gained significant attention as innovative induction motors specifically designed for FESS. Much research has focused on the characteristics of the new multiunit outer rotor HIM, the electromagnetic properties of HIM, and the equivalent magnetic circuit model of HIM [32][33][34]. Other areas of investigation include dual-rotor induction motors (DRIMs) and axial flux induction motors (AFIMs) for FESS.…”

The operation of the electricity network has grown more complex due to the increased adoption of renewable energy resources, such as wind and solar power. Using energy storage technology can improve the stability and quality of the power grid. One such technology is flywheel energy storage systems (FESSs). Compared with other energy storage systems, FESSs offer numerous advantages, including a long lifespan, exceptional efficiency, high power density, and minimal environmental impact. This article comprehensively reviews the key components of FESSs, including flywheel rotors, motor types, bearing support technologies, and power electronic converter technologies. It also presents the diverse applications of FESSs in different scenarios. The progress of state-of-the-art research is discussed, emphasizing the use of artificial intelligence methods such as machine learning, digital twins, and data-driven techniques for system simulation, fault prediction, and life-assessment research. The article also addresses the challenges related to current research and the application of FESSs. It concludes by summarizing future directions and trends in FESS research, offering valuable information for further advancement and improvement in this field.

“…As a key component of energy conversion in the FES system (FESS), the performance of the electrical machine would directly determine the energy conversion efficiency of FESS [4]. Permanent magnet homopolar inductor machine (PMHIM) has received extensive attention in the field of FESS due to its merits such as simple structure, rotor robustness, and high efficiency [5]- [7]. However, for the difficulty of adjusting the air-gap flux generated by the PM, the PMHIM operating in the standby state would cause large no-load electromagnetic loss, which reduces the energy conversion ratio, especially in the long standby operation state.…”

An Active Power Filter with Energy Storage and Double DC Conversion for Power Surge Compensation

This paper presents a single-phase power filter with an energy storage bidirectional DC/DC converter, both of which are equipped with separate capacitor-based DC links that provides good transient response and reduce energy storage capacity. The device is dedicated to the compensation of active power surges generated by nonlinear loads characterized by intermittent operation, where the operating time of a device in relation to the idle time is relatively short. As a compensated and filtered object, the single-phase spot welding machine with a thyristor current controller was assumed. In the case of such devices, the feeder has to be dimensioned for the peak loads, which increase the cost of installation—due to the fact that the used components have to be oversized. The proposed solution can produce measurable economic benefits by reducing the rated power necessary to energize periodically operating loads and improve the indicators of electrical energy quality. An elaborated control algorithm based on a switchable control structure provides a fast and good transient response. The work contains a comprehensive analysis of storage sizing, confirmed by simulation results performed in the Matlab and Simulink environment. Based on the analyses carried out, the laboratory model of the device was implemented and experimental verification performed.
