Abstract
An electrical power source includes a power converter and either an electrical generator or an electrical energy storage device. Power flow is controlled through control of the power converter based on a voltage source and resistance model of the electrical power source. A power converter for an electrical generator is controlled to synthesize a constant voltage of the voltage source and a variable value of the resistance. The resistance value is controlled to deliver a maximum available output power to the electrical microgrid over a range of microgrid voltages up to a voltage below a maximum allowable voltage of the electrical microgrid. For an electrical energy storage device, the power converter is controlled to synthesize a resistance value of the resistance that is dependent upon a phase angle between the voltage at the microgrid side of the electrical power source and current of the electrical energy storage device.
