Thanks to the unique advantages such as long life cycles, high power density and quality, and minimal environmental impact, the flywheel/kinetic energy storage system (FESS) is gaining steam recently.
The core element of a flywheel consists of a rotating mass, typically axisymmetric, which stores rotary kinetic energy E according to (Equation 1) E = 1 2 I ω 2 [J], where E is the stored kinetic energy, I is the flywheel moment of inertia [kgm 2], and ω is the angular speed [rad/s]. In order to facilitate storage and extraction of electrical …
The minimum speed of the flywheel is typically half its full speed, the storage energy is be given by ½ (1 2-0.5 2) I f w f 2 where I f is the rotor moment of inertia in kgm 2 and the w f maximum rotational speed in rad/s. The power level is controlled by the size of the M/G, so this is independent of the rotor.

Moment of inertia depends on the flywheel mass and geometry [1] as follows: (2) I = ∫ r 2 d m where r is the distance of each differential mass element dm to the spinning axis.. The bi-directional power converter transforms electrical energy at the machine frequency into DC electrical energy and vice versa.
How the Flywheel Works. The flywheel energy storage system works like a dynamic battery that stores energy by spinning a mass around an axis. Electrical input spins the flywheel hub up to a high speed and a standby charge keeps the unit spinning until its called upon to release . its energy. The energy is proportional to its mass and speed …
