Flywheel power systems, also known as flywheel energy storage (FES) systems, are power storage devices that store kinetic energy in a rotating flywheel. The flywheel rotors are coupled with an integral motor-generator that is contained in the housing. The motor-generator is used to store and then harness energy from the rotating flywheel.
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.
Vaal University of Technology, Vanderbijlpark, Sou th Africa. Abstract - This study gives a critical review of flywheel energy storage systems and their feasibility in various applications. Flywheel energy storage systems have gained increased popularity as a method of environmentally friendly energy storage.
The use of new materials and compact designs will increase the specific energy and energy density to make flywheels more competitive to batteries. Other opportunities are new applications in energy harvest, hybrid energy systems, and flywheel's secondary functionality apart from energy storage.

The flywheel energy storage system presents certain DC power characteristics through the motor controller, and can therefore be connected to the AC grid through a Voltage Source
Flywheel energy storage systems provide highly responsive clean power that increases the reliability of an energy grid.
The MG must be brush-less, with AC current being generated by the inverter for motoring, and then AC current is converted back to DC in generator mode. In most cases, the MG is connecteddirectlyto
The design of a flywheel energy storage system often necessitates different types of power supplies, primarily either direct current (DC) or alternating current (AC).
Flywheel energy storage (FES) works by spinning a rotor (flywheel) and maintaining the energy in the system as rotational energy. When energy is extracted from the system, the flywheel''s rotational
