Flywheel Energy Storage Systems (FESS) rely on a mechanical working principle: An electric motor is used to spin a rotor of high inertia up to 20,000-50,000 rpm. Electrical energy is thus converted to kinetic energy for storage. For discharging, the motor acts as a generator, braking the rotor to produce electricity.
The speed of the flywheel undergoes the state of charge, increasing during the energy storage stored and decreasing when discharges. A motor or generator (M/G) unit plays a crucial role in facilitating the conversion of energy between mechanical and electrical forms, thereby driving the rotation of the flywheel .
The flywheel energy storage systems can be used for stability design in high power impulse load in independent power systems [187, 188]. A combined closed-loop based on the genetic algorithm with a forward-feed control system with fast response and steady accuracy is designed .
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.
