Zusammenfassung:As the penetration of wind generation in power systems continues to increase, so is the importance that system planners become comfortable with the implications and impact of the wind generation models they are utilizing in system studies. Frequency-control techniques (Bode diagrams and block-diagram algebra) are an effective means for attaining such comfort level. The paper illustrates use of such techniques by examining the reactive power control aspects of a widely-used Type 3 (DFIG) wind-generation model. The different layers of such control are discussed, from control of the individual generators to that of the wind-farm as a whole. The significant differences in speed between those layers of control have implications on assumptions to be made when conducting studies involving significant wind generation penetration. The effect of alternative settings on the speed and stability of the wind farm-level controls is also examined.
