First-generation flywheel energy-storage systems use a large steel flywheel rotating on mechanical bearings. Newer systems use carbon-fiber composite rotors that have a higher tensile strength than steel and can store much more energy for the same mass. To reduce friction, magnetic bearings are sometimes used instead of mechanical bearings.
The regulation speed and response time of the unit are significantly improved. Additionally, AGC compensation is increased. In summary, the flywheel energy storage system has shown promising results in improving the operational flexibility of thermal power units. Both steady-state and dynamic operations can be optimized with the assistance of FESA.
A coordinated control scheme for the thermal power unit with flywheel energy storage array is proposed. Frequency modulation and AGC instruction tracking scenario models are constructed and simulated. AGC regulation indicators are conducted and analyzed to evaluate the unit's performance.
The flywheel energy storage system is also suitable for frequency modulation. In power generation enterprises, the primary flexible operation abilities of the units which will be evaluated by the power grid are their frequency regulation and automatic generation control (AGC) instruction tracking capabilities.
Thanks to the unique advantages such as long life cycles, high power density, minimal environmental impact, and high power quality such as fast response and voltage stability, the flywheel/kinetic energy storage system (FESS) is gaining attention recently.
Indeed, the development of high strength, low-density carbon fiber composites (CFCs) in the 1970s generated renewed interest in flywheel energy storage. Based on design strengths typically used in commercial flywheels, σ max /ρ is around 600 kNm/kg for CFC, whereas for wrought flywheel steels, it is around 75 kNm/kg.
