These are: • In the absence of smooth continuous energy, to provide continuous smooth energy. For example, in reciprocating motors, flywheels are used because the torque produced by the motor is discontinuous. • A flywheel is used to store energy and then release it. In some cases, energy is released at a speed that the energy source cannot.

Share this post. Flywheel energy storage systems (FESS) are a great way to store and use energy. They work by spinning a wheel really fast to store energy, and then slowing it down to release that energy when needed. FESS are perfect for keeping the power grid steady, providing backup power and supporting renewable energy sources.
Some of the applications of FESS include flexible AC transmission systems (FACTS), uninterrupted power supply (UPS), and improvement of power quality [15] pared with battery energy storage devices, FESS is more efficient for these applications (which have high life cycles), considering the short life cycle of BESS, which
