It is necessary to install flywheel energy storage (FES) system in distributed generation, which can improve the quality and the reliability of electric power. The proposed system is composed of four parts: flywheel, magnetic bearing, motor/generator, and power converter.
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.
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.
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 .
The principle of flywheel energy storage FESS technology originates from aerospace technology. Its working principle is based on the use of electricity as the driving force to drive the flywheel to rotate at a high speed and store electrical energy in the form of mechanical energy.
Fly wheels store energy in mechanical rotational energy to be then converted into the required power form when required. Energy storage is a vital component of any power system, as the stored energy can be used to offset inconsistencies in the power delivery system.
