A second class of distinction is the means by which energy is transmitted to and from the flywheel rotor. In a FESS, this is more commonly done by means of an electrical machine directly coupled to the flywheel rotor. This configuration, shown in Fig. 11.1, is particularly attractive due to its simplicity if electrical energy storage is needed.

There are a few key reasons. First, flywheels are quick to adapt to changes in power demand, so they can supply power when it is most needed. This is particularly crucial for renewable energy sources because they can be unpredictable. Second, unlike batteries, flywheels have a long lifespan and don''t lose their effectiveness over time.
