1. A microgrid power generation system comprising:
a power bus having at least one of (a) an AC power bus, (b) a DC power bus, (c) an AC power plane and (d) a DC power plane;
a first controllable AC combustion generator electrically coupled to the power bus for supply of electrical power thereto and having:
(i) a first data bus interface for receipt of a first set-point data defining its power;
(ii) at least one load electrically coupled to the power bus;
(iii) a flywheel energy storage device electrically coupled to the power bus and having a second data bus interface for receipt of state control data that selectively causes the flywheel energy storage device to supply and absorb electrical power from the power bus; and
a microgrid controller connected to the first controllable AC combustion generator and the flywheel energy storage device through the first and second data bus interfaces and having:
(a) a primary control loop configured to maintain a predetermined voltage and/or frequency on the power bus adaptively adjusting power delivery and power absorption of the flywheel energy storage device, and
(b) a secondary control loop arranged to adaptively adjust supply of electrical power to the power bus by increasing or decreasing power generation of the first controllable AC combustion generator in accordance with at least one control variable.
