What is a flywheel energy storage system (fess)?

1. Introduction Flywheel energy storage systems (FESSs) store mechanical energy in a rotating flywheel that convert into electrical energy by means of an electrical machine and vice versa the electrical machine which drives the flywheel transforms the electrical energy into mechanical energy.

What is flywheel energy storage?

Flywheel energy storage (FES) is a kind of physics energy storage method exploiting a rotational block with kinetic energy that changes with the rotational speed varying [2, 3]. The speed-increasing flywheel stores energy when it is accelerated by a motor, which obtains electrical power from the grid through power electronic device driving.
