Flywheel energy storage (FES) works by accelerating a rotor (flywheel) to a very high speed and maintaining the energy in the system as rotational energy.
The operational mechanism of a flywheel has two states: energy storage and energy release. Energy is stored in a flywheel when torque is applied to it. The torque increases the rotational speed of the flywheel; as a result, energy is stored. Conversely, the energy is released in the form of torque to the connected mechanical device .
There are losses due to air friction and bearing in flywheel energy storage systems. These cause energy losses with self-discharge in the flywheel energy storage system. The high speeds have been achieved in the rotating body with the developments in the field of composite materials.
The basic function of the flywheel is to convert the mechanical energy for the end-use application, which is electrical energy. For this conversion, an electromechanical machine is required which could be a motor/generator set. Generator and motor: When the kinetic energy is being stored, the motor is used to drive the flywheel.
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 .
Flywheel energy storage systems have a long working life if periodically maintained (>25 years). The cycle numbers of flywheel energy storage systems are very high (>100,000). In addition, this storage technology is not affected by weather and climatic conditions . One of the most important issues of flywheel energy storage systems is safety.
