State-of-the-Art of the Flywheel/Li-ion Battery Hybrid Storage System for Stationary Applications

This thesis presents the State-of-the-Art of a flywheel/Li-ion battery Hybrid Energy Storage System for stationary applications. As Renewable Energy Sources increase in the grid so do the stability problems associated with their intermittency. Here the importance of Energy Storage Systems that aim to provide many grid services. The complementary features of the two devices in terms of power, energy and discharge time candidate this hybrid system as an optimal solution to support future grids.
