The working principle of flywheel energy storage: under the condition of surplus power, the flywheel is driven by electric energy to rotate at a high speed, and the electric energy is converted into mechanical energy for storage; when the system needs it, the. . The flywheel energy storage system (FESS) of a mechanical bearing is utilized in electric vehicles, railways, power grid frequency modulation, due to its high instantaneous power and fast response. However, the lifetime of FESS is limited because of significant frictional losses in mechanical. . Flywheel energy storage (FES) works by spinning a rotor (flywheel) and maintaining the energy in the system as rotational energy. There is noticeable progress in FESS, especially in utility, large-scale deployment for the electrical grid, and renewable energy applications. The core technology is the rotor material, support bearing, and electromechanical control system. Compared with other energy storage systems, FESSs offer numerous advantages, including a long lifespan, exceptional efficiency, high power density, and minimal environmental impact.
