What is a flywheel energy storage system (fess)?

The flywheel energy storage system (FESS) offers a fast dynamic response, high power and energy densities, high efficiency, good reliability, long lifetime and low maintenance requirements, and is particularly suitable for applications where high power for short-time bursts is demanded.

What are the main research directions for flywheels?

In terms of flywheel itself, the main further research directions include further improving the energy density and specific energy (can be achieved by advanced flywheel materials), decreasing investment cost, and reducing self-discharging losses (can be realized by advanced bearing such as superconducting bearing and machine technology).

How does a power converter work?

In the charging process, the flywheel gains speed and stored kinetic energy is increased. In the discharging mode, the flywheel works as a prime mover and the machine controlled by the power converter works as a generator, so the electrical energy is released and converted to electrical energy feeding to the grid or supplying loads.
