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.
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 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 .
A flywheel is an inertial energy storage device. It absorbs mechanical energy and serves as a reservoir, storing energy during the period when the supply of energy is more than the requirement and releases it during the period when required and releases it during the period when the requirement of energy is more than the supply.
A flywheel energy storage system consists of bearings, a rotating mass, a motor-generator, and a frequency inverter. Fig. 14.4 shows the main components of a flywheel energy storage system . The design of the components influences the overall efficiency, and can help in reducing power transmission losses.
