The use of new materials and compact designs will increase the specific energy and energy density to make flywheels more competitive to batteries. Other opportunities are new applications in energy harvest, hybrid energy systems, and flywheel’s secondary functionality apart from energy storage.
Flywheel energy storage (FES) works by accelerating a rotor (flywheel) to a very high speed and maintaining the energy in the system as rotational energy.
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.
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.
This explains its popularity in applications that require high energy capacities and are weight-sensitive, such as automotive and consumer electronics. Comparing to batteries, both flywheel and super-capacitor have high power density and lower cost per power capacity. The drawback of supercapacitors is that it has a narrower discharge
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 .
