Coordinated control of rotor side converter and grid side converter on 15 kW DFIG using cascaded feedback linearization controllers

The coordinated control system is an emerging topic in the electrical field for generating the required power. The coordinated system control includes Rotor Side Converter (RSC) and Grid Side Converter control. It is applicable to the Doubly Fed Induction Generator (DFIG) to generate the needed power outcome. However, the traditional current controller method has recorded a high oscillation torque signal, reducing the power generation percentage. Hence, this research mainly intends to control the oscillation torque signal and offer a better stability range. Hence, a novel Buffalo-based Hysteresis Control system to control the gird current and the Voltage is regulated by the Proportional-Integral controller. In addition, the 15 kW wind power system is designed in MATLAB/SIMULINK environment. Hence, the managed RSC can quickly track the DC link reference voltage. Using the proposed controller, the Voltage of the DFIG coordinated system is varied up to 500 V. Also, the minimum Integral Square Error reported in the proposed model is 1.2 for 1 s time series, which verified the stability of the proposed DFIG system. Also, its processing time is 5 min, which is quite better than the compared models.
