Flywheel Energy Storage Systems (FESS) convert electricity to kinetic energy, and vice versa; thus, they can be used for energy storage. High technology devices that directly use mechanical energy are currently in development, thus this scientific field is among the hottest, not only for mobile, but also for stationary applications.
For doubly-fed flywheel energy storage, there is a large operating control of rotor speed during normal operation, which can run from a sub-synchronous turndown rate of 0.5 to a super-synchronous turndown rate of 1.5, that is, the doubly-fed flywheel can provide 75% of the kinetic energy of the flywheel rotor.

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.
