Flywheel energy storage (FES) is a very interesting technology. Fig. 9.3 shows the working principle of FES.

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 flywheel energy storage systems (FESSs).
In this storage scheme, kinetic energy is stored by spinning a disk or rotor about its axis. Amount of energy stored in disk or rotor is directly proportional to the square of the wheel speed and rotor׳s mass moment of inertia. Whenever power is required, flywheel uses the rotor inertia and converts stored kinetic energy into electricity .
The energy storage facility provided by flywheels are suitable for continuous charging and discharging options without any dependency on the age of the storage system. The important aspect to be taken note of in this regard is the ability of FES to provide inertia and frequency regulation .
