Execution of advanced solar‐shunt active filter for renewable power application

Energy Conversion and Economics, Volume 2, Issue 2, Page 100-118, June 2021., 2021
Abstract This manuscript proposes a novel Solar‐shunt active filter (solar‐SHAF) controller for improving the power flow in a larger power‐application. The proposed fault and non‐linear detection unit (FANDU) avails faster disturbance detection. A novel FAND regulator (FANDR) is suggested to disconnect the solar power generation from the considered ...

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
