Flywheel energy storage (FES) works by accelerating a rotor (flywheel) to a very high speed and maintaining the energy in the system as rotational energy.
The major components that make up a flywheel configured for electrical storage are systems comprising of a mechanical part, the flywheel rotor, bearings assembly and casing, and the electric drive part, inclusive of motor-generator and power electronics.
According to Al-Diab (2011) the flywheel energy storage system (FESS) could be exploited beneficially in dealing with many technical issues that appear regularly in distribution grids such as voltage support, grid frequency support, power quality improvement and unbalanced load compensation.
Flywheel systems are composed of various materials including those with steel flywheel rotors and resin/glass or resin/carbon-fiber composite rotors. Flywheels store rotational kinetic energy in the form of a spinning cylinder or disc, then use this stored kinetic energy to regenerate electricity at a later time.
To connect the Flywheel Energy Storage System (FESS) to an AC grid, another bi-directional converter is necessary. This converter can be single-stage (AC-DC) or double-stage (AC-DC-AC). The power electronic interface has a high power capability, high switching frequency, and high efficiency.
A 30 MW flywheel grid system started operating in China in 2024. Flywheels may be used to store energy generated by wind turbines during off-peak periods or during high wind speeds. In 2010, Beacon Power began testing of their Smart Energy 25 (Gen 4) flywheel energy storage system at a wind farm in Tehachapi, California.
