Energy storage in a flywheel is realized by a spinning mass in the form of kinetic energy [144,145]. The flywheel energy storage system is mainly composed of a rotor, magnetic bearing systems, a vacuum housing and an electric machine [142,145].
Flywheel energy storage system (FESS) is an electromechanical system that stores energy in the form of kinetic energy. A mass coupled with electric machine rotates on two magnetic bearings to decrease friction at high speed. The flywheel and electric machine are placed in a vacuum to reduce wind friction.
Flywheel energy storage system has many merits, such as high power density, long lifetime, accurate implementation to monitor the load state of the power system, and insensitivity to the ambient temperature. The flywheel energy storage research began in the 1980s in China.
The shortcomings of theoretical study and insufficient industrial study severely impede the mass manufacture of flywheel energy storage system. It is generally acknowledged that the gap between the flywheel energy storage technology in China and other developed countries is more than 10 years.
A flywheel is driven by a reversible electric machine that initially operates as a motor to supply energy to the inertial mass. With the drive system disconnected, the flywheel stores energy in its rotation. Upon request, this latter will be transformed into electrical energy by the generator.
