1. A method for determining energy changes using a power converter to minimize an impact of a disturbance, the power converter having energy storage elements and switching elements, the method comprising:

  • determining a nature of the disturbance;

    evaluating an amount of energy to be added or removed based on the disturbance determination; and

    based on the evaluated amount of energy to be added or removed, determining an operating sequence of the switching elements using a computer processor, wherein the operating sequence provides a sequencing of the switching elements, and switching times and operating durations of each of the switching elements in the power converter based on available energy levels of the energy storage elements before and during the addition or removal of the evaluated amount of energy, thereby minimizing the impact of the disturbance on outputs of the power converter.
