The Impact of Wind Generation on Low Frequency Oscillation in Power Systems

Integration the renewable energy resources (RES) with the modern power system is increased in the last decays due to its environmental and economic benefits. In contrast these technologies impact on the dynamic behavior of the power system. In this paper, the effect of wind turbine penetration level on the low frequency oscillations is investigated. Both local and interarea oscillation modes are covered in the study. Two types of wind turbine are selected here; fixed speed wind turbine (FSWT) and double-fed induction generator (DFIG). The impact of the existence of the FSWT and the penetration level of the DFIG on the electromechanical oscillations are conducted. The results show that the penetration level of the wind turbine is highly impact on the low frequency oscillations. Some local modes are highly affected by these types of generation.
