This paper investigates virtual inertia control of doubly fed induction generator (DFIG)‐based wind turbines to provide dynamic frequency support in the event of sudden power change. The relationships among DFIGs' virtual inertia, rotor speed and network frequency variation are analysed, and a novel virtual inertia control strategy is proposed. The proposed control strategy shifts the maximum power...
This paper investigates the control scheme of the permanent magnet synchronous generator (PMSG)-based wind turbines to damp the power system oscillations. Above all, a novel fault ride through control strategy based on the energy transmission is proposed to maintain the dc side voltage of the full scale power converter during grid faults and the damping control process. Following that, a further investigation...
This paper investigates virtual inertia control of doubly fed induction generator (DFIG)-based wind turbines to provide dynamic frequency support in the event of abrupt power change. The model and control scheme of the DFIG is analysed. The relationships among the virtual inertia, the rotor speed and the network frequency variation are then investigated. The “hidden” kinetic energy that can be released...
