Due to the advantage of flywheel, minimizing the operation times of BESS and giving priority of flywheel to respond the fluctuations is proved to be an available option to improve the life span of BESS, reduce the probability of explosion of BESS and secure operation of the hybrid energy storage system.
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.
However, the high cost of purchase and maintenance of solar batteries has been a major hindrance. Flywheel energy storage systems are suitable and economical when frequent charge and discharge cycles are required. Furthermore, flywheel batteries have high power density and a low environmental footprint.
A steel alloy flywheel with an energy storage capacity of 125 kWh and a composite flywheel with an energy storage capacity of 10 kWh have been successfully developed. Permanent magnet (PM) motors with power of 250–1000 kW were designed, manufactured, and tested in many FES assemblies.
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 .
