LVRT Control Strategy for Asymmetric Faults of DFIG Based on Improved MPCC Method
IEEE Access, 2021 In the case of asymmetric fault, the modern new power grid requires that the doubly-fed induction generator (DFIG) still has good low voltage ride-through (LVRT) capabilities. To solve this problem, a low voltage ride-through control strategy based on an
