This paper presents the study, design and analysis of a distributed generation system, considering an environment composed of two photovoltaic systems connected to the utility grid with distinct features, the first system consists of a full-bridge single phase inverter and L filter, which is current controlled, and operates by injecting active current into the grid and mitigating harmonic currents of non-linear loads. In addition, the second system consists of a single-phase full-bridge inverter with LCL filter, which is voltage controlled and operates by injecting current into the grid and compensating reactive loads connected to the PCC. Thus, the operation as active power filter performed by both systems is based on the synchronous reference frame (SRF) by means of a three-phase fictitious system. In addition, both systems employ the MPPT technique based on the algorithm Perturbe and Observe to perform the extraction of the maximum power of its photovoltaic arrays. Finally, from computational simulations and experimental results, the proposed system performance is evaluate.
