A flywheel is a very simple device, storing energy in rotational momentum which can be operated as an electrical storage by incorporating a direct drive motor-generator (M/G) as shown in Figure 1. The electrical power to and from the M/G is transferred to the grid via inverter power electronics in a similar way to a battery or any other non-synchronous
