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