A series hybrid "real inertia" energy storage system

The intermittent and irregular nature of renewable energy sources necessitates at least some form of energy storage if uninterrupted supply is to be achieved [1].Mismatches in supply and demand need to be accounted for on a wide range of time scales, from the order of weeks or months as a result of diurnal and seasonal variations [2], to seconds and milliseconds.

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. 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 increase in the speed of th
