Abstract: The operation of the electricity network has grown more complex due to the increased adoption of renewable energy resources, such as wind and solar power. Using energy storage technology can improve the stability and quality of the power grid. One such technology is fly-wheel energy storage systems (FESSs).
The amount of energy stored, E, is proportional to the mass of the flywheel and to the square of its angular velocity is calculated by means of the equation (1) E = 1 2 I ω 2 where I is the moment of inertia of the flywheel and ω is the angular velocity. The maximum stored energy is ultimately limited by the tensile strength of the flywheel material.

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.
