“…A rail transit vehicle has a large mass and a great deal of braking kinetic energy. By introducing braking recovery and energy storage systems, energy conservation and emission reduction goals can be achieved [132]. According to Radcliff, the investment payback period for a 1 MW FESS applied to the London Underground is five years.…”

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.

“…In [7], [11] is presented with more detail a comparison of different ESS. In [12] an experimental test is presented of the installation of an off-board inertia flywheel in a substation in Madrid, Spain, stating that the combination of different ESS technologies could provide a more efficient and reliable system. With the advancement of technology, it was possible to create solutions based on very compact and desirable implemented on-board flywheels, as used in Rotterdam [13].…”

With the continuous expansion of the railway power systems, the integration of high speed locomotives and the need to increase the overhead catenary line power capacity, the main shortcomings of the conventional railway feeding system are becoming more evident. In order to overcome these drawbacks and to contribute to the technological evolution with innovative and electrically more efficient systems, several solutions have been proposed and implemented. In this context, this paper briefly presents a study of different railway power systems, highlighting emerging concepts, such as regenerative braking, energy storage systems, the inclusion of renewable energy sources, bidirectional power flow and wireless power transfer. Some of these concepts can be implemented in short to medium term, or in the long term. Following these concepts, an overview of the power electronics challenges for the implementation of these emerging concepts is presented and discussed.

“…In order to reduce the voltage fluctuation of the DC network and improve the energy efficiency, the conventional diode rectifier is replaced by the controlled rectifiers in [8,9,17]. The installation of storage devices (such as super-capacitors or flywheels) [18][19][20][21][22][23][24][25] at substations or tracksides could be a good way to absorb the surplus regenerated energy and regulate DC voltage. However, compared with inverters, storage devices require more installation space, higher cost, and more safety constraints [17].…”

This paper presents a new hybrid simulation method for reversible traction power supply systems (RTPSSs) supplied by four-quadrant converters (4QC). RTPSSs overcome several drawbacks of conventional DC electrification systems, such as wasting of braking energy, output voltage fluctuation, and low power factor at light load conditions. The paper introduces the system topology of a RTPSS and illustrates its advantages over standard DC systems. A hybrid simulation method is proposed to study the performance of the RTPSS taking into account the dynamics of multiple trains. This hybrid simulation integrates train motion, steady-state and transient-state models, and is able to evaluate both the system-level steady-state performance (voltage, current, power and energy) and the equipment-level transient-state performance (harmonics, ripple, power factor and stability). Structure and signals flow of this hybrid simulation system have been introduced, and the methodology of modeling has been presented. The validity and applicability of the proposed hybrid simulation method have been proved by a case study of a 10 km railway line with 6 substations. To date, no other work has accomplished the steadystate and transient-state study using a single integrated simulation.
