Stability Analysis of a Grid‐Connected DFIG Wind Farm Using Static VAR Compensator

Journal of Electrical and Computer Engineering, Volume 2026, Issue 1, 2026.
The integration of wind farms has greatly impacted the stability and performance of power systems. This is primarily due to the intermittent nature of wind energy, which requires advanced control strategies and robust grid‐integration techniques. This paper employs a Static VAR Compensator (SVC) equipped with a proportional integral (PI) controller to ...
