1. A method for controlling a state of charge (SOC) of an energy storage device in an energy system, the method comprising:

  • determining a current SOC of the energy storage device;

    receiving a polynomial bias factor in response to invoking a polynomial function;

    calculating a dynamic SOC bias based on the polynomial bias factor and a difference between the current SOC and a desired SOC of the energy storage device;

    controlling the SOC to be within a desired SOC range in accordance with the polynomial bias factor and the regulation signal,wherein the polynomial function can be dynamically adjusted based on characteristics of a regulation signal of the energy system.
