Abstract: A method for operating a microgrid electric power generation system includes delivering energy to an electric power bus at least partially from one or more kinetic generators electrically coupled to the electric power bus, controlling the one or more kinetic generators in response to a change in a load such that a magnitude of a voltage on the electric power bus remains within a predetermined voltage range, and controlling one or more combustion generators electrically coupled to the electric power bus based at least in part on an operating state of the one or more kinetic generators. The one or more kinetic generators are capable of (a) delivering energy stored therein to the electric power bus, and (b) storing energy in kinetic form.

Abstract: A flywheel system includes a rotor configured to rotate about a rotation axis. The flywheel system further includes a fixture and an active magnetic bearing module for actively stabilizing the rotor relative to the fixture. The active magnetic bearing module includes a plurality of first magnetizable elements mechanically coupled to or integrated in the rotor, and a plurality of electromagnets mechanically coupled to the fixture and configured to magnetically couple with the plurality of first magnetizable elements to actively stabilize the rotor relative to the fixture. Each of the first magnetizable elements is farther than each of the electromagnets from the rotation axis.
