Flywheel energy storage (FES) works by spinning a rotor (flywheel) and maintaining the energy in the system as rotational energy. 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. W

Analysis of Flywheel Energy Storage Systems for Frequency

However, with AC to DC converters, the flywheel energy storage system (FESS) is no longer tied to operate at the grid frequency. FESSs have high energy density, durability,

The use and role of flywheel energy storage systems

Flywheels, in short, are machines that store kinetic energy in a rotating mass. The flywheel operates via a "flywheel effect"whereby its rotation is maintained via its own inertia [1].
