Flywheel Energy Storage Systems and their Applications: A
Flywheel energy storage systems have gained increased popularity as a method of environmentally friendly energy storage. Fly wheels store energy in mechanical rotational energy to
Flywheel Energy Storage Systems (FESS) rely on a mechanical working principle: An electric motor is used to spin a rotor of high inertia up to 20,000-50,000 rpm. Electrical energy is thus converted to kinetic energy for storage. For discharging, the motor acts as a generator, braking the rotor to produce electricity.
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 way, the kinetic energy is converted back into electrical energy, and the flying wheel acts as a mechanical battery. Often, the mass used in the flywheel is shaped like a hollow cylinder . Fig. 6 shows the configuration of the prototype FES using a conventional induction motor and ball bearings.
Application areas of flywheel technology will be discussed in this review paper in fields such as electric vehicles, storage systems for solar and wind generation as well as in uninterrupted power supply systems.
