Flywheel energy storage (FES) works by accelerating a rotor (flywheel) to a very high speed and maintaining the energy in the system as rotational energy.
A flywheel energy storage system consists of bearings, a rotating mass, a motor-generator, and a frequency inverter. Fig. 14.4 shows the main components of a flywheel energy storage system . The design of the components influences the overall efficiency, and can help in reducing power transmission losses.
Think of it as a mechanical storage tool that converts electrical energy into mechanical energy for storage. This energy is stored in the form of rotational kinetic energy. Typically, the energy input to a Flywheel Energy Storage System (FESS) comes from an electrical source like the grid or any other electrical source.
The energy storage facility provided by flywheels are suitable for continuous charging and discharging options without any dependency on the age of the storage system. The important aspect to be taken note of in this regard is the ability of FES to provide inertia and frequency regulation .
The kinetic energy stored in the flywheel is presented in Eq. (1). where is the stored energy, is the moment of inertia, is the rotational speed. The speed of the flywheel undergoes the state of charge, increasing during the energy storage stored and decreasing when discharges.
The energy stored in a vehicle-mounted flywheel system is typically low, being of similar magnitude to the kinetic energy of the vehicle operating at a moderate speed.
