of a Grid-Connected Inverter In this section‚ the modeling and control of a grid-connected inverter with dual-loop control using the capacitor current feedback is described. Although‚ this issue has already been addressed in available literatures‚ the goal is introducing a simplified block diagram which make designing controllers easier. A grid-connected inverter with the LCL filter is shown in Fig. 1. The LCL filter consists of an inverter-side inductor L1‚ a filter capacitor C‚ and a grid-side
