1. A method for controlling a power generation system, the method comprising:

  • determining, with a computing device, a phase angle error associated with tracking the power generation system based on measurement signals received from one or more voltage transducers;

    determining, with the computing device, a scaling factor based on the phase angle error, the scaling factor corresponding to a value ranging from zero to one when the phase angle error exceeds the predetermined error threshold and a value of one for all phase angle errors below the predetermined error threshold;

    generating, with the computing device, a current command for controlling the operation of a power convertor of the power generation system; and

    applying, with the computing device, the scaling factor to the current command such that the current command is reduced when the phase angle error exceeds a predetermined error threshold.
