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.

The primary types include mechanical flywheels, magnetic bearings, and composite flywheel systems, which each utilize distinct technologies to optimize energy retention and discharge.

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.
