Hello Zubair,

in order for a DFIG to control reactive power, it comes down to how your are controlling the DFIG. This is very dependent on how the DFIG is being used and how you have attatched drives to it.

Here is a good example to look at one way to use a DFIG: https://www.mathworks.com/help/physmod/sps/examples/wind-farm-dfig-detailed-model.html#:~:text=Wind%20turbines%20using%20a%20doubly,AC%20IGBT%2Dbased%20PWM%20converter.&text=In%20this%20example%20the%20wind,the%20speed%20at%201.2%20pu.

Regards,

Joel
