The main challenge for wind turbines is the grid voltage sag. Hence, the grid codes (GCs) define the tasks of both wind turbine and grid in different conditions e.g. grid voltage sag. The GCs force the wind turbine to remain connected to the grid and injects the reactive current in voltage sag that this action is well-known as a low-voltage ride-through (LVRT). The grid voltage sag may lead to dc-link overvoltage in permanent magnet synchronous generator (PMSG)-based wind turbine, which connects by back-to-back (BTB) converter to the grid. The BTB converter consists of a machine side converter (MSC) and a grid-side converter (GSC). This paper proposes the improved MSC controller, which uses de-loading droop to adapt the generated active power of PMSG in the grid voltage sags. In fact, the reference current of MSC is determined by grid voltage according to the grid voltage sag to implement the reactive current injection according to GC by GSC. To verify the performance of the proposed controller, it is simulated in MATLAB/Simulink environment and compared with conventional de-loading droop that uses the dc-link voltage as the input signal. The simulation results confirm the effectiveness of the proposed controller in enhancing LVRT.
