Output Impedance Modeling of Single-Phase Grid-Tied Inverters With Capturing the Frequency-Coupling Effect of PLL

The output impedance model for the precise stability analysis on the single-phase grid-tied inverters considering the frequency-coupling effect of the phase-locked loop (PLL) is studied. A multifrequency admittance matrix (MAM) is developed to predict the inverter-grid system stability by applying t...
