This paper investigates the grid support strategy of a VSC-HVDC link for the DFIG-based wind farm integration, including grid frequency regulation and power oscillation damping. The VSC-connected configuration may reduce the power system inertia with fast power control. In order to improve the power system stability with fast penetration of wind power generation, the control strategy of the VSC-HVDC...
This paper proposes a novel control strategy for Doubly Fed Induction Generator (DFIG) based wind power system and Permanent Magnet Synchronous Generator (PMSG) based wind power system during grid voltage dips. Based on a comparative study, the rotor over-current of DFIG and DC-link over-voltage of PMSG are identified as two main issues during grid voltage dips. A novel control strategy is proposed...
This paper presents the Direct model reference adaptive internal model controller for doubly fed induction generator used in wind farms based on MIT Rule adjustment mechanism with dither injection. Direct model reference adaptive internal model controller is developed and it is tuned using MIT rule. Rotor current controller is designed using direct model reference adaptive internal model controller...
As a promising renewable alternative, the wind power is highly expected to contribute a significant part of generation in power systems in the future, but this also bring new integration related power quality issues, which mainly consist of voltage regulation and reactive power compensation. Wind power, as a rule, does not contribute to voltage regulation in the system. Induction machines are mostly...
