The paper presents an investigation in the modeling complexity of parallel grid-connected inverters from similar to different LCL filters parameters. In fact, Micro-Grids (MGs) are generally architectures including inverters based LCL filters with different inductive and capacitive parameters. Consequently, the MG complexity increases because of the coupling effect between the different filters, thereby several phenomena may appear, such as resonance frequency that may deeply affect the MG stability. Regarding this issue and in order to illustrate the complexity of such MG system, its modeling for n similar filters, two and three filters with different parameters had been performed. Thus simulations were carried out in order to perform both Bode diagram frequency analysis and grid- and inverters-sides currents analysis.
