Abstract—This paper proposes a method to control the output

power of a wind farm with the aim of improving the transient stability

of a multi-machine power system. Doubly fed induction generators

(DFIG) are considered for the variable speed wind farms.

The variation of the frequency of the DFIG terminal bus is used

to modulate the torque reference and thus the output power of the

DFIG in the post-disturbance condition. This in turn modifies the

electrical power of the nearby alternators and causes improvement

of stability. The proposed control technique is validated in WSCC

3-machine 9-bus system and IEEE 16-machine 68-bus system. The

study is carried out in PSCAD/EMTDC as well as in MATLAB

platforms.
