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.
Flywheels with the main attributes of high energy efficiency, and high power and energy density, compete with other storage technologies in electrical energy storage applications, as well as in transportation, military services, and space satellites .
Flywheel Systems are more suited for applications that require rapid energy bursts, such as power grid stabilization, frequency regulation, and backup power for critical infrastructure. Battery Storage is typically a better choice for long-term energy storage, such as for renewable energy systems (solar or wind) or home energy storage.
Flywheel Energy Storage System (FESS) is an electromechanical energy storage system which can exchange electrical power with the electric network. It consists of an electrical machine, back-to-back converter, DC link capacitor and a massive disk.
Motor/Generator: This component drives the flywheel and also converts the kinetic energy back into electricity. Bearings: Advanced bearings help reduce friction, allowing the flywheel to maintain its speed. Power Electronics: These regulate the flow of electricity in and out of the system.
However, due to the recent improvements in materials, magnetic bearings, power electronics, and the introduction of high speed electric machines, FESS have been established as a solid option for energy storage applications [7, 8, 9, 26, 27]. A flywheel stores energy that is based on the rotating mass principle.
