When energy is extracted from the system, the flywheel's rotational speed is reduced as a consequence of the principle of conservation of energy; adding energy to the system correspondingly results in an increase in the speed of the flywheel. . and high power quality such as fast response and voltage stability, the flywheel/kinetic energy storage system (FESS) is gaining attention recently. There is noticeable progress in FESS, especially in utility, large-scale deployment for the electrical grid, and renewable energy applications. This. . Using energy storage technology can improve the stability and quality of the power grid. Compared with other energy storage systems, FESSs offer numerous advantages, including a long lifespan, exceptional efficiency, high power. . Flywheel energy storage is an exciting solution for efficient and sustainable energy management. Flywheel energy storage systems have gained increased popularity as a method of environmentally friendly energy storage.
