“…The flywheel is made up of a disk, an electrical machine, a large capacitor, source converters, and control systems. The main component of the technology, which is the flywheel, has, over the years, supported the smooth running of machines [60]. Steel is the most common material used for flywheels, but recently, the use of composite materials has been encouraged.…”

This review presents a detailed summary of the latest technologies used in flywheel energy storage systems (FESS). This paper covers the types of technologies and systems employed within FESS, the range of materials used in the production of FESS, and the reasons for the use of these materials. Furthermore, this paper provides an overview of the types of uses of FESS, covering vehicles and the transport industry, grid leveling and power storage for domestic and industrial electricity providers, their use in motorsport, and applications for space, satellites, and spacecraft. Different types of machines for flywheel energy storage systems are also discussed. This serves to analyse which implementations reduce the cost of permanent magnet synchronous machines. As well as this, further investigations need to be carried out to determine the ideal temperature range of operation. Induction machines are currently stoutly designed with lower manufacturing cost, making them unsuitable for high-speed operations. Brushless direct current machines, the Homolar machines, and permanent magnet synchronous machines should also be considered for future research activities to improve their performance in a flywheel energy storage system. An active magnetic bearing can also be used alongside mechanical bearings to reduce the control systems’ complications, thereby making the entire system cost-effective.

“…They are stable but low loss bearing systems due to less friction and are suitable for high-speed applications in FESS [55]. Magnetic bearings that use permanent magnets for levitation are called passive magnetic bearings whereas active bearings are the type that make use of a feedback system with electrical coils [56]. Active magnetic bearings require continuous power for energisation of the magnetic levitation system [13].…”

Flywheel energy storage systems (FESS) are one of the earliest forms of energy storage technologies with several benefits of long service time, high power density, low maintenance, and insensitivity to environmental conditions being important areas of research in recent years. This paper focusses on the electrical machine and power electronics, an important part of a flywheel system, the electrical machine rotating with the flywheel inertia in order to perform charge-discharge cycles. The type of machine used in the electrical drive plays an important role in the characteristics governing electrical losses as well as standby losses. Permanent magnet synchronous machine (PMSM) and induction machines (IM) are the two most common types of electric machines used in FESS applications where the latter has negligible standby losses due to its lower rotor magnetic field until energised by the stator. This paper describes research in which the operational and standby losses of a squirrel-cage induction machine-based flywheel storage system (SCIM-FESS) are modelled as a system developed in MATLAB/Simulink environment inclusive of the control system for the power electronics converters. Using the proposed control algorithm and in-depth analysis of the system losses, a detailed assessment of the dynamic performance of the SCIM-FESS is performed for different states of charging, discharging, and standby modes. The results of the analysis show that, in presence of system losses including aerodynamic and bearing friction losses, the SCIM-FESS has satisfactory characteristics in energy regulation and dynamic response during load torque variations. The compliance of FESS and its conversion between the generating and motoring mode within milliseconds show the responsiveness of the proposed control system. Appl. Sci. 2019, 9, 4537 2 of 26 there are various solutions proposed to ensure network stability and reliability with RES including demand management, interconnection with external grids, and ESS [5].There are ranges of systems involved in energy storage process, which can convert, store and deliver energy on demand. Performance of these systems depends on the amount of energy they can store, the storage time and delivery of energy with minimum losses [6]. Therefore, high power capability, high efficiency, low capital cost and environmentally friendly attributes improve the value of ESS [7].A FESS is an assembly of a rotating mass, electrical machine, power electronics converter, bearing system and containment. The design of the rotor used in FESS depends on the materials from which they are made. Solid disk or solid cylinder are made from isotropic materials like steel. Rim type or hollow cylinder flywheel rotors are constructed from non-isotropic material like composite carbon fiber. Solid disk or solid cylinder flywheel rotors have simple construction and are commonly used [8]. Solid rotor flywheels exhibit less displacement from axes due to centrifugal forces hence simplifying flywheel attachment to the shaft and with ele...

“…Another example is a miniature flywheel energy storage system that had an AMB supporting a 1.01 kg rotor. A flywheel energy storage device that had a 200 kg rotor spinning at a maximum rotation speed of 9000 rpm was also supported by an active magnetic radial bearing (AMRB); the analysis showed that the sum of the core loss and copper loss was less than 200 W [84]. Finally, a flywheel energy storage system that had an axial flux permanent magnet synchronous motor/generator integrated with an active magnetic thrust bearing (AMTB) was also proposed [85]; the goals of this design were to reduce the part counts and the system complexity.…”
