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.
The operation of the electricity network has grown more complex due to the increased adoption of renewable energy resources, such as wind and solar power. Using energy storage technology can improve the stability and quality of the power grid. One such technology is flywheel energy storage systems (FESSs).
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.
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 .
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.

Flywheels reduce grid dependency, lower energy costs during peak usage, and provide long-term savings due to their durability and low maintenance. Discover the role of flywheel energy storage in improving EV charging stations, offering rapid power response, grid support, and enhanced efficiency.
Flywheel power storage systems in production as of 2001 had storage capacities comparable to batteries and faster discharge rates. They are mainly used to provide load leveling for large battery systems, such as an uninterruptible power supply for data centers as they save a considerable amount of space compared to battery systems.
On a high level, flywheel energy storage systems have two major components: a rotor (i.e., flywheel) and an electric motor. These systems work by having the electric motor accelerate the rotor to high speeds, effectively converting the original electrical energy into a stored form of rotational energy (i.e., angular momentum). The flywheel continues to store …
