Flywheel energy storage systems (FESS) are considered environmentally friendly short-term energy storage solutions due to their capacity for rapid and efficient energy storage and release, high power density, and long-term lifespan. These attributes make FESS suitable for integration into power systems in a wide range of applications.
Moreover, flywheel energy storage system array (FESA) is a potential and promising alternative to other forms of ESS in power system applications for improving power system efficiency, stability and security . However, control systems of PV-FESS, WT-FESS and FESA are crucial to guarantee the FESS performance.
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, σmax /ρ is around 600 kNm/kg for CFC, whereas for wrought flywheel steels, it is around 75 kNm/kg.
A flywheel energy storage unit is a mechanical system designed to store and release energy efficiently. It consists of a high-momentum flywheel, precision bearings, a vacuum or low-pressure enclosure to minimize energy losses due to friction and air resistance, a motor/generator for energy conversion, and a sophisticated control system.
Flywheel Energy Storage Systems (FESS) rely on a mechanical working principle: An electric motor is used to spin a rotor of high inertia up to 20,000-50,000 rpm. Electrical energy is thus converted to kinetic energy for storage. For discharging, the motor acts as a generator, braking the rotor to produce electricity.
Compared to battery energy storage system, flywheel excels in providing rapid response times, making them highly effective in managing sudden frequency fluctuations, while battery energy storage system, with its ability to store large amounts of energy, offers sustained response, maintaining stability .
