The impact of large-scale grid-connected PV (photovoltaics) on power system transient stability is discussed in this paper. In response to an increase of PV capacity, the capacity of conventional synchronous generator needs to be reduced relatively. This leads to the lower system inertia and the higher generator reactance, and hence, the power system transient stability may negatively be affect...

The increasing complexity of interconnected power system has brought challenges to detailed dynamic simulation in terms computational effort. Therefore, for transient stability assessment, equivalents parts large-scale are required capture the electromagnetic transients. This paper presents a review past research on equivalencing using coherency-based methods and identification methods. Future ...

When geomagnetic disturbances (GMDs) occur, the reactive power loss (GIC-Q) caused by geomagnetically induced currents (GICs) flowing through transformers can lead to system instability. Previous studies have been focused on impacts of GMD static stability conventional systems, while transient hybrid systems left unexplored. In this article a based wind and energy sources are proposed as resear...
