Claim 11:
12. A method of operating a power system comprising:
coupling, by transitioning a first clutch assembly to a closed state, a turbine shaft of a turbine assembly to a first end of a generator shaft of a generator assembly;
coupling, by transitioning a second clutch assembly to a closed state, a flywheel shaft of an inertia assembly to a second end of the generator shaft at the second end, the inertia assembly further including a flywheel coupled to the flywheel shaft;
operating the power system in a power generation mode while the first clutch assembly is in the closed state;
opening the first clutch assembly into an open state to decouple the turbine shaft from the generator shaft and the flywheel; and
operating the power system in a synchronous condenser mode while the first clutch assembly is in the open state, wherein the second clutch assembly enables operation of the power system in a standard inertia synchronous condenser mode and a high inertia synchronous condenser mode, the power system having a first inertia constant when operating in the standard inertia synchronous condenser mode and a second inertia constant when operating in the high inertia synchronous condenser mode, the second inertia constant being greater than the first inertia constant by at least a factor of 2.5.
