This paper presents a literature review of the impacts of large-scale wind power integration through multiple Wind Power Plants (WPPs) on the power system transient stability and inter-area power oscillations. The Wind Turbine Generator (WTG) topologies considered in this review are the Doubly-Fed Asynchronous Generator (DFAG), Type-3 and the Full-Converter Unit, Type-4 WTGs. The reason is that these are the dominate types in the existing and planned installations of wind power generation. Also, the different modeling approaches of the WTGs will be reviewed, especially the aggregated generic models approach which is the most-likely approach in case of stability analysis of large systems. Finally, a review of the different counter measures, implemented through the WPPs controllers, proposed to mitigate these impacts will be presented.
