Claim Text:
1. A method for controlling the operation of a power generation system configured to supply power to an electrical grid, the method comprising: detecting an occurrence of an islanding event associated with the power generation system, wherein the islanding event is caused by an opening of one or more phase conductors; adjusting a regulator gain applied within a regulator of the power generation system to an islanding gain value in response to the detection of the islanding event, wherein the islanding gain value exceeds a maximum gain value defined for the regulator in the event of an occurrence of any ride-through transient event; controlling a power converter of the power generation system based on a control signal generated by the regulator as the power generation system is being isolated from the electrical grid, the control signal being generated within the regulator as a function of the islanding gain value; and shutting down the power generation system upon isolation of the power generation system from the electrical grid.
