Claim 14:
15. A power generator system comprising:
an alternator coupled to an engine configured to supply power to a power grid,
an automatic voltage regulator configured to supply reactive power support, and
a controller configured to:
identify a maximum voltage value and a minimum voltage value based on an average of a plurality of mains voltage values;
detect an abrupt voltage change by determining whether an instantaneous mains voltage value is above the maximum voltage value or below the minimum voltage value;
determine an operating mode associated with a power factor and a reactive power of the genset based on the detected abrupt voltage change; and
adjust, based on the operating mode, an amount of reactive current either supplied to the power grid or consumed by the power generator system for a period of time.
