Abstract: A power system having a plurality of gensets compares the instantaneous power consumption with a plurality of power consumption zone boundaries and classifies the power consumption into a selected zone. Each zone includes a corresponding base power value and a corresponding dynamic range value, which are apportioned among the plurality of gensets.

Abstract: A method and a system of managing load sharing among a plurality of power sources are disclosed. According to certain embodiments, the method includes determining a total power output to be directed from the plurality of power sources to at least one power consumer. The method also includes retrieving a Brake Specific Fuel Consumption (BSFC) curve associated with each of the plurality of power sources. The method further includes determining an operating priority for each of the plurality of power sources based on operating constraints associated with the respective power source. The method further includes determining a load share for each of the plurality of power sources based on at least the total power output, the BSFC curves, and the operating priorities.
