Optimization Configuration of Grid-Connected Inverters to Suppress Harmonic Amplification in a Microgrid

This paper provides insight into the optimal configuration scheme of grid-connected inverters based on harmonic amplification suppression. The connection changes natural resonance frequencies grid. Hence, a reasonable can optimize impedance distribution and shift to frequency bands farther away from sources. We proposed site selection determination number suppress amplification. modal sensitivities (MFSs) were obtained by analysis (RMA). Moreover, concepts security region insecurity illustrated. sites be calculating participation factors (PFs) in region. Furthermore, was determined building Norton equivalent circuit inverter evaluating output at each frequency. Finally, simulations Matlab/Simulink modified IEEE-9 bus microgrid utilized verify effectiveness scheme.
