The design of the motor for flywheel energy storage mainly adopts the stator core, winding, magnet, and a matching optimization to improve the power and efficiency. The challenge in motor design is to reduce the loss of the permanent magnet motor rotor and prevent the failure of the motor caused by high-temperature rise. 3.3.
The main power circuit technology is mature, and the main research is the conversion control algorithm. China has successfully developed MW-class motor converters for flywheel energy storage systems. 4. FES System
The theoretical exploration of flywheel energy storage (FES) started in the 1980s in China. The experimental FES system and its components, such as the flywheel, motor/generator, bearing, and power electronic devices, were researched around thirty years ago.
Flywheels have a solid foundation for reliability in meeting the demands of utility scale energy storage. For instance, the M25 system has a rated energy storage capacity of 25 kilowatt hours (kWh) at the beginning of the project, with a 4-hour discharge duration (6.2kW power rating).
Utility-scale energy storage systems for stationary applications typically have power ratings of 1 MW or more . The largest flywheel energy storage is in New York, USA by Beacon Power with a power rating of 20 MW and 15 min discharge duration .
The economic analysis and evaluation of the flywheel energy storage for the power grid frequency regulation showed that the more running actual utilizing of the set power, the higher the benefit/cost ratio is, which could be up to 1.97 .
