Flywheel Energy Storage System (FESS) is an electromechanical energy storage system which can exchange electrical power with the electric network. It consists of an electrical machine, back-to-back converter, DC link capacitor and a massive disk.
Flywheels are now a possible technology for power storage systems for fixed or mobile installations. FESS have numerous advantages, such as high power density, high energy density, no capacity degradation, ease of measurement of state of charge, don’t require periodic maintenance and have short recharge times .
Flywheels, one of the earliest forms of energy storage, could play a significant role in the transformation of the electri-cal power system into one that is fully sustainable yet low cost.
Policies and ethics Flywheel energy storage stores electrical energy in the form of mechanical energy in a high-speed rotating rotor. The core technology is the rotor material, support bearing, and electromechanical control system. This chapter mainly introduces the main structure of...
