1. A method comprising:
detecting, by a controller, a fault associated with electrical power;
determining, by the controller, a power regulation mode from a set of power regulation modes, responsive to detecting the fault, each of the set of power regulation modes associated with a corresponding parameter to control, based on a reference input signal associated with the corresponding parameter;
switching, by the controller, the power regulation mode to an offset power regulation mode responsive to identifying the power regulation mode;
adjusting, by the controller, a value of a parameter from a normal value to an offset value, wherein the parameter is selected based on the offset power regulation mode, wherein the offset value is different for each of the set of power regulation modes;
maintaining, by the controller, the value of the parameter as the offset value for a period of time to regulate an amount of reactive current consumed; and
modifying, by the controller, the value of the parameter from the offset value to the normal value, and the power regulation mode from the offset power regulation mode to the identified power regulation mode after the period of time.
