Improved LVRT grid code under Islanding condition [PDF]
IECON 2015 - 41st Annual Conference of the IEEE Industrial Electronics Society, 2015 The grid code Low Voltage Ride Through (LVRT) requires Renewable Energy Sources (RESs) to remain connected to the grid following the voltage sags resulting from disturbances. The LVRT pattern is based on voltage sag magnitude and its duration at Point of Common Coupling (PCC) and only voltage reflects the internal dynamics of RES.
