Abstract

A system and method for controlling voltage at a point of common coupling of a wind farm including a plurality of wind turbines is provided. The method includes: calculating a first voltage error value, which is a difference between a reference voltage value of the point of common coupling and an actual voltage value of the point of common coupling; calculating a compensation reference voltage value based on the first voltage error value; calculating a second voltage error value by subtracting a voltage value of an output terminal of a wind turbine from a sum of a reference voltage value of the wind turbine and the compensation reference voltage value; calculating a reactive power compensation value corresponding to the second voltage error value; and injecting a reactive current corresponding to the reactive current compensation value into a power grid.
