Resumen

With the increasing penetration of distributed energy resources (DERs) into islanded Microgrids (MGs), grid-forming inverters (GFI) have become the key element interfacing renewable energy sources (RES). Usually, the GFI is employed with an output filter to minimize the harmonics content achieving high-quality output voltage regulation. To this end, model predictive control (MPC) has been widely proposed to control the output voltage of GFI systems due to the high-quality performance, fast control response, and straightforward handling of constraints. However, an accurate model of the system is required for the conventional MPC to avoid a sub-optimal performance under uncertainties. To overcome this known drawback, a novel Model-Free Predictive Control MF-PC is proposed in this paper. Consequently, the output voltage of an LCL-filtered GFI is regulated without knowledge of the physical model.
