Hybrid Fuzzy-PI Control of DFIG Power Associated With a Variable Speed Wind Energy Conversion System

The rotor side converter (RSC) controls active and receptive powers at the stator side of DFIG. The turbine current in axis d (id) is modeled utilizing the parameters of a 660 kW wind turbine. The appraised wind speed within the specified wind turbine is 15 (m/s) and the wind cut-in and cut-out speed is 4 (m/s) and 25 (m/s) individually. In this paper, we utilized tuning the hybrid fuzzy PI controller based on the Mamdani inference system and selecting the triangular membership functions, and compare with three strategies. The proposed strategy is way better than a conventional PID controller, fuzzy logic, and hybrid fuzzy-PI controllers with Gaussian membership functions for active and reactive power control. Simulation and comparison think about are utilized to appear the effectiveness of the proposed hybrid fuzzy-PI controllers with triangular membership functions and fewer errors, ripple, and overshoot have been gotten.
