Abstract
An electric power system includes an engine, a generator driven by the engine, an electrical energy storage device, power control circuitry coupling the generator and storage device together, and a processor coupled to the circuitry. The generator provides variable AC power and the storage device provides variable DC power to the circuitry. The processor executes operating logic to provide control signals to the circuitry to operate the generator at a first speed to provide a first level of AC electricity, increase the DC power provided from the storage device to increase the AC electricity to a second level, increase operating speed of the generator from the first speed to a second speed greater than the first speed, decrease the DC power from the storage device as the operating speed of the generator increases, and limit acceleration of the operating speed to reduce perception of a speed change.
