Voltage Fault Ride Through (Vfrt) Study Template and Assessment Guide (v3)

Voltage Fault Ride -Through (VFRT) is defined as the ability of a unit to stay connected to the electrical grid during and following a fault disturbance. With the increasing level of Inverter Based Resource (IBR) / Power Electronics (PE) generation, the power system dynamics are also changing due to the decreasing governor response and less synchronous inertia while creating a negative impact on frequency and voltage stability of the grid.
