| Abstract |
In this article, the admittance model for LCL-type grid-connected inverter with proportional PCC voltage feedforward control is built to design the passivity. It is found that if the LCL parameters are designed in a certain range, i.e., _rsup._s/6 and _L1Cinf._s/3 (_r is the resonance frequency of the LCL filter, _L1C is the resonance frequency of the inverter-side inductor and the filter capacitor and _s is the sampling frequency), the passivity can be achieved while the grid background harmonics can also be well suppressed. The simulation and experimental results verify the correctness of the theoretical analysis. |
