The technology is referred to as a flywheel energy storage system (FESS). The amount of energy stored is proportional to the mass of the rotor, the square of its rotational speed and the square of its radius. Flywheel energy storage consists in storing kinetic energy via the rotation of a heavy object. Find out how it works.

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.

The idea with a flywheel for power storage is that a small amount of electricity is used to keep a heavy mass rotating at a very high speed — 10,000 revolutions per minute (rpm) or faster. Then when power interruptions happen or some extra power is needed to stabilize the grid, that flywheel generates power, gradually slowing down in
