Sensitivity of Voltage Sags Estimation to Uncertainties
IEEE Access, 2023 Voltage sags are power quality disturbances mainly caused by faults with a highly random nature. For this reason, the severity and frequency of occurrence of voltage sags is typically analyzed by means of probabilistic methods, such as Monte Carlo ...

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

Voltage Sag Detection Based on Rectified Voltage Processing [PDF]
IEEE Transactions on Power Delivery, 2004 An algorithm for voltage sag detection based on rectified voltage processing is presented and its performances are evaluated by means of simulated and real voltage waveforms (recorded at some low-voltage busbars and measured on a scaled prototype of a voltage support system). The algorithm is intended to detect voltage sag occurrence and to trigger the
