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.
A flywheel operates on the principle of storing energy through its rotating mass. Think of it as a mechanical storage tool that converts electrical energy into mechanical energy for storage. This energy is stored in the form of rotational kinetic 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 50 MW peak power can be supplied for about 13 s, with an overall efficiency of 91–95%. The flywheels are connected in parallel to a 1200 V DC-link. Similar PM flywheels have previously been tested in urban traffic busses and rail systems with a resulting energy save of up to 40% . 3.5.8. UPS system
Whenever power is required, flywheel uses the rotor inertia and converts stored kinetic energy into electricity . In the present scenario, flywheels of 1 kW power storage capacity for 3 h and 100 kW for 30 s have been successfully developed. Design of Larger wheel to store 250 kW power for 10–15 min is under progress.
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.
