Abstract

As wind power retains a significant proportion of generation mix in the electric system, we foresee that less fossil fuel units will be on service. Under this situation, it may impact system's frequency security due to the lack of frequency support from units. To make up for such a system change, wind turbines should actively provide frequency response upon request. For wind turbines to achieve this goal, active power output of the wind turbine should be controllable so that the generating margin could be preserved for frequency response. Therefore, the presentation of this paper will begin with the demonstration of the control scheme for the doubly fed induction generator (DFIG). Simulation results validate the effectiveness of the methodology in regulating wind power upon operator's request, while stability is assured under variant wind speeds. Following that, this paper will explore several operating strategies for DFIGs to support system frequency with less sacrifice in the wind energy production. Simulation results show that the proposed strategies can enhance regulation performance in the high wind penetrated power system.
