Sumario: In comparison to conventional power plants characterized by Synchronous Generators (GS), Distributed Generation units (DG) usually do not have damping or rotational inertia properties. With the increase of DG sources in the electrical system, the impact of low inertia and damping effect on the stability and dynamic performance of the grid increases. A solution to improve the stability of a power system is to provide virtual inertia by Virtual Synchronous Generators (VSG). The article proposes the development of a Virtual Synchronous Generator as a control mechanism for a large DG of the order to 20MW. At the same time, it presents the conventional control strategy of DGs in the Brazilian commercial scenario, the PQ control. With the software PSCAD/EMTDC ® , both control strategies are submitted to a
scenario similar to the National Interconnected System (SIN), composed of disturbances, in order to discuss the contribution of the strategies in the static and dynamic stability of the frequency, proving the efficiency of the Virtual Synchronous Generator strategy in the theme.
