An Online Event-Based Grid Impedance Estimation Technique Using Grid-Connected Inverters
TL;DR: This technique combines an active grid impedance estimation technique, based on variations of the inverter's output power, and the continuous monitoring of the positive-sequence amplitude of the PCC voltage, which will significantly reduce the occurrence of required PQ variations, thus minimizing the power losses and the impact on power quality.
