First-generation flywheel energy-storage systems use a large steel flywheel rotating on mechanical bearings. Newer systems use carbon-fiber composite rotors that have a higher tensile strength than steel and can store much more energy for the same mass. [6]. However, wind and solar power's intermittent nature prevents them from be-ing independent and reliable energy sources for micro-grids. 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. . Mechanical ESS includes pumped water storage systems (PHSS), flywheel ESS (FESS), compressed air ESS (CAESS), and gravity ESS (GESS) [8]. When excess electricity is available, it is used to accelerate a flywheel to a very high speed.
