An Improved Direct Power Control for Doubly Fed Induction Generator
IEEE transactions on power electronics, 2021 A novel voltage-modulated direct power control (VM-DPC) is first designed for a back-to-back (BTB) converter in the doubly fed induction generator (DFIG) system. The proposed VM-DPC is built in the stator stationary reference frame ($\alpha \beta$).
