A new type of generator, a transgenerator, is introduced, which integrates the wind turbine and flywheel into one system, aiming to make flywheel-distributed energy storage (FDES) more modular and scalable than the conventional FDES.

Flywheels can absorb excess energy generated from wind and solar power during periods of high output and release it when generation drops or demand increases. This capability helps smooth out the variability of renewable energy and ensures a consistent power supply.

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.OverviewFlywheel energy storage (FES) works by spinning a rotor () and maintaining the energy in the system as. When energy is extracted from the system, the flywheel's rotational speed is reduced a.

Table 2 lists the maximum energy storage of flywheels with different materials, where the energy storage density represents the theoretical value based on an equal-thickness-disc flywheel rotor.
