The sags and interruptions are the one events that most affect users. For this reason, the need to implement dynamic voltage support or fault ride through (FRT) schemes and to inject reactive current into PV generators is evident.In the present work, a novel methodology for dynamic grid support based on adaptive FRT schemes is described. The control implemented will consider all the fault conditions that can lead to the occurrence of fault-induced delayed voltage recovery (FIDVR) and similar events. Results of those tests and indices calculation carried out for a PV generators linked to the real power system, show that the implemented strategy operates according to the requirements of current standards for different voltage events.
