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. 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 th

This chapter provides an overview of flywheel storage technology. The rotor design and construction, the power interface using flywheels, and the features and key advantages are discussed. The status of flywheel technology is described, including a description of commercial products, specifications, and capital and running costs.
Low-speed flywheels, with typical operating speeds up to 6000 rev/min, are constructed with steel rotors and conventional bearings. For example, a typical flywheel system with steel rotor developed in the 1980s for wind–diesel applications had energy storage capacity around 2 kW h @ 5000 rev/min, and rated power 45 kW.
With that increase in new energy penetration, that frequency variable problem is being exacerbated. In a regional electrical network with a certain wind electricity penetration rate, sag containment is adopted by that wind turbo-charger when that rated wind velocity is falling, and a hybrid containment consisting of sag containment combined with pitch

The motor and drive takes excess electrical energy from the grid and uses it to speed up the rotation of the flywheel, so it is stored as kinetic energy. When a fast injection of power is needed to maintain frequency stability, the regenerative capability of the drive converts the flywheel''s kinetic energy back into electricity within milliseconds.
