Optimizing control parameters is one of the measures to suppress oscillation in new power system. Firstly, a three-port impedance model with input characteristics is established for the grid connected inverter, and the optimal stability region of inner current control parameters considering AC side stability is given. Then the parameters of the control loop are optimized to form the optimal stability region, which is verified by simulation and experiment.
