The main applications of FESS in power quality improvement, uninterruptible power supply, transportation, renewable energy systems, and energy storage are explained, and some commercially available flywheel
Still, FESS stands as a substantial option for energy storage applications after installing high-speed motors and advancement in magnetic bearings, materials, and power electronic devices. 49, 50. Figure 2 illustrates the single line
Using a 2.9 kWh/725 kW FESS, light rail vehicles can save up to 31% of their energy [133]. By connecting the FESS to the DC power grid, it is possible to save 21.6% of the energy, reduce the voltage drop of a substation by 29.8%, and
Using energy storage technology can improve the stability and quality of the power grid. One such technology is flywheel energy storage systems (FESSs). Compared with other energy storage systems, FESSs offer numerous advantages, including a long lifespan, exceptional efficiency, high power density, and minimal environmental impact.
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.
Other opportunities are new applications in energy harvest, hybrid energy systems, and flywheel’s secondary functionality apart from energy storage.
