Advanced Reactive Power Control Technique for Wind Power Application

This study proposes an advanced reactive power control technique (ARPCT) to improve the power quality of grid integrated wind power systems. Looking at the excellent field experience and knowledge of the power operators, recently, FACTS devices are integrated with the existing grid codes to solve undesirable power quality problems. Therefore, to improve the grid stability, high energy quality, protect the system operation and avail better power quality, Statcom based FACTS devices are selected for 9MW wind integrated system application. The proposed model and control technique is developed and simulated through MATLAB/Simulink software. To justify the proposed technique necessity, the Statcom based grid integrated wind energy system performance is compared without Statcom based system application. Moreover, the transient stability of the wind turbine is also tested during the three-phase fault condition (LLG). The proficiency of the modelled regulator and functionality is detailed through theoretical analysis. The compared results indicate the improved results and justify the necessity of the proposed controller.
