Identification of weak locations in bulk transmission systems using voltage stability margin index
TL;DR: In this article, the authors proposed a voltage stability margin index (VSMI) based on the relationship between voltage stability and the angle difference between sending and receiving end buses, which is derived for a simplified two-bus system and later applied to a large system.

Uses and abuses of the swing equation model
TL;DR: It is shown that the swing equation model may lead to erroneous conclusions when performing stability analysis of power systems, even under small oscillations, by comparison with a first principles model.

Penetration impact of wind farms equipped with frequency variations ride through algorithm on power system frequency response
Ayman Attya,Thomas Hartkopf +1 more
TL;DR: In this article, a detailed analysis for the effect of wind farm connection to a power system on the system frequency response is presented, and three basic values are used to estimate the mentioned impact; the time needed to reach the safe margin after a certain droop, the RMS value of frequency deviation after the fault initiation by a given fixed time span and the maximum frequency drop for each event.
