Flywheels can store energy kinetically in a high speed rotor and charge and discharge using an electrical motor/generator. Wheel speed is determined by simultaneously solving the bus regulation and torque equations. . A grid-scale flywheel energy storage system is able to respond to grid operator control signal in seconds and able to absorb the power fluctuation for as long as 15 minutes. OverviewA flywheel-storage power system uses a for, (see ) and can be a comparatively small storage facility with a peak. . Flywheel energy storage (FES) works by spinning a rotor (flywheel) and maintaining the energy in the system as rotational energy.

Compared with other ways to store electricity, FES systems have long lifetimes (lasting decades with little or no maintenance; [5][8] full-cycle lifetimes quoted for flywheels range from in excess of 10 5, up to 10 7, cycles of use), [9] high specific energy (100–130. . Compared with other ways to store electricity, FES systems have long lifetimes (lasting decades with little or no maintenance; [5][8] full-cycle lifetimes quoted for flywheels range from in excess of 10 5, up to 10 7, cycles of use), [9] high specific energy (100–130. . 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. . FESS is used for short-time storage and typically offered with a charging/discharging duration between 20 seconds and 20 minutes. However, one 4-hour duration system is available on the market. If we had enough of them, we could use them to stabilize power grids. Batteries also started out as small fry, so we should not write off flywheels any time soon.
