Modeling method for the current control loop of a grid-connected PWM inverter with the LCL output filter was discussed. Firstly, the current control loop with the LCL inverter-side current as feedback was established. Then, parameters of PI controller were calculated on the basis of an equivalent controlled object. Finally, Norton equivalent circuit for the current control loop of grid-connected system was derived by integrating one control equation, which connected the PWM inverter output voltage and the LCL inverter-side current, with two circuit equations, separately using the LCL inverter-...
