The flywheel energy storage is a physical energy storage method, and it is also one of the few new energy storage technologies that can partially replace electrochemical batteries.
A flywheel stores energy that is based on the rotating mass principle. It is a mechanical storage device which emulates the storage of electrical energy by converting it to mechanical energy. The energy in a flywheel is stored in the form of rotational kinetic energy.
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).
The most common applications of flywheels in electrical energy storage are for uninterruptible power supplies (UPS) and power quality improvement [10, 11, 12]. For these applications, the electrochemical battery is highly mismatched and suffers from an insufficient cycle life, since the number of cycles per day is usually too high .
Their efficiency is high during energy storage and energy transfer (>90 %). The performance of flywheel energy storage systems operating in magnetic bearing and vacuum is high. Flywheel energy storage systems have a long working life if periodically maintained (>25 years).
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. As a result of mechanical failure, the rotating object fails during high rotational speed poses a serious danger. One of the disadvantages of these storage systems is noise.
Electric energy is stored in the flywheel rotor as kinetic energy. The shape and material of the flywheel directly affect the amount of energy that can be stored. The stored energy is directly proportional to the square of the angular velocity and the moment of inertia of the flywheel. When the flywheel rotates, the kinetic energy is expressed as
