Reactive Power Control in Wind Power Plants | SpringerLink

The reactive power control can be used to achieve the coefficient of ideal power in the DFIG connection point. When WTG feeds a strong power system, the reference reactive power can be adjusted for simplicity in zero. For the control of active power, the curve of feature of power-speed is used which is known as the curve of feature of absorption.

What is Reactive Power? | Ansys

What is Reactive Power? Reactive power is power that is reflected back to the grid — as opposed to active power, which is power that is consumed by the load. Similar to the pressure that pushes water through a pipe, voltage acts as the pressure that pushes electrical current through power lines. To do this, voltage draws on reactive power
