    Abstract: A decentralized electrical power allocation system is provided. The system includes a power bus, electric power consumers, and at least two power source assemblies. Each power source assembly includes a power controller and a power source. Each power controller is configured to execute an adaptive droop control scheme so as to cause their respective power sources to output power to meet a power demand on the power bus applied by the power consumers. The power output of a given power source is controlled based at least in part on correlating a power feedback of the given power source with a droop function that represents an efficiency of the given power source to generate electrical power for a given power output. The droop functions are collaboratively defined so that one power source shares more output at lower power levels while another power source shares more output at higher power levels.

    Abstract: A method for generating electric load models that includes receiving a plurality of measurements representative of input provided by a power source to electric loads is provided. The method includes generating a plurality of combination of model loads and assigning a contribution factor to each model load in each combination. The method further includes computing a match index for each combination for each measurement. The match index is computed by comparing a predicted output of each combination with an actual output generated by the electric loads for each input represented by each measurement. Furthermore, the method includes computing a first likelihood index for each combination based on the match index for each combination for the plurality of measurements. The method also includes computing a second likelihood index for each contribution factor in each combination based on the match index for each combination.
