A mathematical model of DFIGimplemented in the d-q reference frame is achieved. Then, a direct power control algorithm for controlling rotorcurrents of DFIG is incorporated using PID controllers, and space-vector modulation (SVM) is used to determinea fixed switching frequency. The condition of the stator side power factor is controlled at unity level via MPPTstrategy. The MRAC which is based on DPC is investigated instead of PID regulators. Also, the performancesof NFC based on DPC are tested and compared to those achieved using MRAC controller. The results obtainedin the Matlab/Simulink environment using robustness tests show that the NFC is efficient, has superior dynamicperformance and is more robust during parameter variations.}, issn = {2083-4195}, pages = {27--39}, url = {https://papers.itc.pw.edu.pl/index.php/JPT/article/view/757} }
