This paper has presented a novel control method of DFIG connected to the grid under variable wind speed and dynamic mode during the system operation. The control method is deeply done in the DFIG converter's control. The parameter controls which applied in grid side control are electromagnetic torque and DC link voltage, whereas in the rotor side, the converter uses DFIG rotor speed and reactive power. The electromagnetic torque has been used as an essential part in the GSC control instead of grid reactive power. Both GSC and RSC are used back to back converters with two-level IGBT devices which the pulses are generated from the PWM. The simulation carried out using PSCAD/EMTDC program. The results show that, this method is a suitable to apply in DFIG with variable wind speed in dynamic operation and steady state. And also the validation of the method reliability has been demonstrated.
