Grid-Forming and Grid-Following Inverter Comparison of Droop Response

Dynamic Voltage Support of Grid-Forming Inverters

“…Reactive current injection is achieved by introducing and implementing droop based reactive current control [7]. In [8] and [9], an algorithm with the use of droop control has been presented to coordinate active and reactive current, improving the voltage profile of the system. In [10] during the voltage drop, reactive current target value is set directly to the Q-axis based on the prevalent voltage situation while taking into consideration the rated current of the inverter.…”
