Claim 18:
19. A system comprising:
a first power generating unit configured to be electrically coupled to a load via a power bus, the first power generating unit comprising:
first and second power converters configured to receive first direct current output from a first power source, a first sensor configured to be coupled to the power bus, the first and second power converters, the first power source, and the first sensor disposed onboard a first vehicle; and
a first controller operatively coupled to the first and second power converters and disposed onboard the first vehicle, wherein the first controller is configured to detect a fault condition corresponding to the first power converter, and control, responsive to detecting the fault condition, a load current conducted through the power bus via the second power converter; and

a second power generating unit configured to be electrically coupled to the power bus, the second power generating unit comprising:
third and fourth power converters configured to receive second direct current output from a second power source, a second sensor configured to be coupled to the power bus, the third and fourth power converters, the second power source, and the second sensor disposed onboard a second vehicle; and
a second controller operatively coupled with the third and fourth power converters and disposed onboard the second vehicle,

wherein the second controller is configured to receive electrical signals sensed by the second sensor indicative of the load current output by the second power converter and conducted through the power bus,
the second controller configured to alter one or more droop characteristics corresponding to the third and fourth power converters based on the load current that is output by the second power converter controlled so that a total electrical power demand of a load is met uninterrupted.
