Energy conversion of flywheel energy storage system
Flywheel energy storage (FES) works by accelerating a rotor () to a very high speed and maintaining the energy in the system as .When energy is extracted from the system, the flywheel's rotational speed is reduced as a consequence of the principle of ; adding energy to the system correspondingly results in an increase in the speed of th. In FESSs, electric energy is transformed into kinetic energy and stored by rotating a flywheel at high speeds. An FESS operates in three distinct modes: charging, discharging, and holding.
In FESSs, electric energy is transformed into kinetic energy and stored by rotating a flywheel at high speeds. An FESS operates in three distinct modes: charging, discharging, and holding.
Whenever power is required, flywheel uses the rotor inertia and converts stored kinetic energy into electricity [17].
Flywheel energy storage (FES) can have energy fed in the rotational mass of a flywheel, store it as kinetic energy, and release out upon demand.
