Research on the Resonance Suppression Method for Parallel Grid-Connected Inverters Based on Active Impedance
Under the condition of weak grid, the coupling between parallel inverters and grid impedance is easy to cause harmonic resonance, which seriously affects the grid-connected power quality. First, the equivalent circuit model of the multi-inverter parallel system is established, and the mechanism of h...
