Summary:The high integration of Distributed Generation (DG) into the conventional electric system brings many challenges to the operating sector, in view of the growing concern associated with the reliability of the system and the quality of the energy generated. Moreover, the main sources of DG do not have control over the production of active power, besides being dependent of the algorithm of MPPT (Maximum Power Point Tracking). On the other hand, DG units are normally coupled to the power grid through fast-response power converters, which do not possess any inertia, affecting stability of the electric system. This paper presents a control method for the voltage source inverter (VSI) of DG units based on virtual synchronous generator (VSG). The technique to be used is the Synchronverter, enabling control over the active and reactive powers generated, regardless of grid operating conditions, by acting in grid maintenance. Simulation results suggest the effectivity of the Synchronverter.
