Abstract:
1. A method, comprising: conditioning output power from a first type of power source to provide electric power to a DC bus; inverting DC electric power from the DC bus to provide AC electric power to one or more AC electrical loads; measuring an AC power demand by the one or more AC electrical loads; monitoring a power output capacity of the first type of power source; determining a difference between the power output capacity of the first type of power source and the AC power demand; controlling a power storage device to provide power to the DC bus based on the difference; monitoring the one or more AC electrical loads to determine if the AC power demand has changed; and based on a change in the AC power demand, adjusting an AC output power of a second type of power source to provide power from the second type of power source to the DC bus to meet the AC power demand of the one or more AC electrical loads when the power output capacity of the first type of power source is less than the AC power demand.
