1. A method for controlling a power generation system, the method comprising:
- determining a phase angle error associated with tracking the power generation system;
determining a scaling factor based on the phase angle error;
generating a current command for controlling the operation of a power convertor of the power generation system; and
applying the scaling factor to the current command such that the current command is reduced when the phase angle error exceeds a predetermined error threshold.

Abstract
In one aspect, a method for controlling a power generation system may generally include determining a phase angle error associated with the power generation system, determining a scaling factor based on the phase angle error, generating a current command for controlling the operation of a power convertor of the power generation system and applying the scaling factor to the current command such that the current command is reduced when the phase angle error exceeds a predetermined error threshold.
