Cause, Classification of Voltage Sag, and Voltage Sag Emulators and Applications: A Comprehensive Overview [PDF]
IEEE Access, 2020 The large-scale application of wind power and photovoltaic power solves the energy crisis and alleviates the environmental problems caused by the use of conventional energy. However, they are at risk of being randomly tripped from the network when faced to voltage sag and severe fault events, which will lead to a sudden reduction of active power output
