First-generation flywheel energy-storage systems use a large steel flywheel rotating on mechanical bearings. Newer systems use carbon-fiber composite rotors that have a higher tensile strength than steel and can store much more energy for the same mass. When energy is extracted from the system, the flywheel's rotational speed is reduced as a consequence of the principle of conservation of energy; adding energy to the. . This paper will review how energy is stored in a flywheel using the simple concept of a massive ball attached to a limited strength string. Image used courtesy of Sino Voltaics.

One such technology is flywheel energy storage systems (FESSs). Compared with other energy storage systems, FESSs offer numerous advantages, including a long lifespan, exceptional efficiency, high power density, and minimal environmental impact. The energy is stored as kinetic energy and can be retrieved by slowing down the flywheel. . The rest of the flywheel is now severely unbalanced, which may lead to rapid bearing failure from vibration, and sudden shock fracturing of large segments of the flywheel. This efficient design allows for rapid charging and discharging, optimizing energy transfer and reducing mechanical energy loss. Fly wheels store energy in mechanical rotational energy to be then converted into the required power form when required.
A FESS consists of several key components: (1) A rotor/flywheel for storing the kinetic energy. (2) A bearing system to support the ro-tor/flywheel. (4) Other aux-iliary. . 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. For discharging, the motor acts as a generator, braking the rotor to. . Energy storage flywheels are usually supported by active magnetic bearing (AMB) systems to avoid friction loss. Therefore, it can store energy at high efficiency over a long duration. While the technology has been around for decades as a form of Uninterrupted Power Supply (UPS) to provide power when main sources fail, it has more recently begun to be. .
2 shows the main circuit topology of the flywheel energy storage system based on the Back-Back dual PWM converter, which consists of a grid-side LCL filter, a back-to-back dual PWM converter, a permanent magnet synchronous motor, a flywheel rotor, etc. Electrical energy is thus converted to kinetic energy for storage. The core. . diagram of the layout is shown in Figure 1. Flywheel energy storage uses electric motors to drive the flywheel to rotate at a high speed so that the electrical power is transformed into mechanical power and stored,and when necessary ed in flywheel energy storage systems (FESS).
