Abstract
The present application provides a method and apparatus for suppressing grid voltage imbalance. By obtaining a 90° lagged grid voltage through a differential tracker, calculating instantaneous power using the 90° lagged grid voltage, and then calculating a power converter voltage according to the instantaneous power, the suppression of grid voltage imbalance may be achieved.
