It stores energy on the rotating mass principle. The whole flywheel energy storage system (FESS) consists of an electrical machine, bi-directional converter, bearing, DC link capacitor, and a massive disk. Its high efficiency (90%–95%) is its major advantage in all ESS.
The operation of the inertial storage system is based on the conversion of energy into a kinetic form, which is then converted to electrical energy when necessary. A flywheel is driven by a reversible electric machine that initially operates as a motor to supply energy to the inertial mass.
The shortcomings of theoretical study and insufficient industrial study severely impede the mass manufacture of flywheel energy storage system. It is generally acknowledged that the gap between the flywheel energy storage technology in China and other developed countries is more than 10 years.
During energy storage, electrical energy is transformed by the power converter to drive the motor, which in turn drives the flywheel to accelerate and store energy in the form of kinetic energy in the high-speed rotating flywheel . The motor then maintains a constant speed.
Three types of electric machines can be coupled to the storage system: switched reluctance machine (SRM), synchronous machine (SM), and induction machine (IM). A SRM is the least used due to its high current waves and complex controls. SM and IM are commonly used for high-speed and high-power applications, respectively.
Nowadays, energy storage for stand-alone wind systems can be attained in various ways. Nevertheless, the inertial energy storage adjusts to sudden power variations of the wind generator, and allows useful power-to-weight characteristics in the power storage and delivery systems.
