A Wind-Power Generation System Having a Function of Suppressing Line Voltage Deviation

Wind-power generation (WPG) tends to create voltage deviation in the distribution lines because wind speed always fluctuates. This paper proposes to add a new function to the interface converter of WPG, that is, generation of reactive power to suppress the voltage deviation caused by WPG itself. This paper also proposes a reactive power control strategy for the interface converter to suppress the voltage deviation. The validity is verified by simulation studies.
