摘要（英）：

The invention relates to an LCL parameter and control parameter design method and an LCL parameter and control parameter design device for improving grid impedance adaptability. Through theoretical calculation and actual requirements, specific values of an active damping coefficient k, a current controller proportional coefficient k

, an open-loop transfer function cutoff frequency omega,a resonant frequency omega and an inverter side LC resonant frequency omega are obtained through calculation, thus the integrated design of LCL parameters and control parameters can be realized, and the inverter with high adaptability to grid impedance variation can be obtained by adopting the inverter designed in the invention without additional compensation links or hardware equipment.
