1. A method of controlling a first electrical power source, the first electrical power source being in parallel operation with at least one other electrical power source to supply an electrical load, the method comprising the steps of:

  • generating a desired reference voltage signal;

    sensing an output voltage generated by the first electrical power source;

    sensing an output current generated by the first electrical power source; and

    compensating the desired reference voltage signal with an integration of the sensed output voltage and a proportion of the sensed output current to maintain proper division of the electrical load on a per unit basis.
