Fault ride-through of renewable energy conversion systems during voltage recovery

Journal of Modern Power Systems and Clean Energy, 2016
Asymmetrical voltage swells during recovery of a short-circuit fault lead to fluctuations in the dc-link voltage of a renewable energy conversion system (RECS), and may induce reversed power flow and even trip the RECS. This paper studies characteristics

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 ...
