2. Series hybrid kinetic energy storage (SHyKESS) The presented hybrid energy storage system, refereed to as SHyKESS, falls into a category of systems that the authors would term "series" type systems.

The inertia of the power system plays a crucial role in determining the frequency dynamics and stability of the power system [2], [3], [4].

Flywheel energy storage (FES) works by accelerating a rotor to a very high speed and maintaining the energy in the system as rotational energy. When energy is extracted from the system, the flywheel''s rotational speed is reduced as a consequence of the principle of conservation of energy ; adding energy to the system correspondingly results in an
