Abstract
The paper presents the results of analyzing the effectiveness of the proposed structure of a system for automatically controlling the grid-tie inverter of renewable energy sources based on a current-controlled virtual synchronous generator (CC-VSG) carried out using the developed linearized model of the proposed system and the small-signal stability analysis. The developed model has been verified, and the presented study results reflect the specific features of the proposed control system in comparison with the conventional structure of a voltage-controlled VSG (VC-VSG). It has been proven that the proposed CC-VSG model shows stable operation under small perturbations of the operating parameters over a wide range of network density variations. At the same time, an effective response speed and damping level that ensure an acceptable inertial response have been achieved. It has also been determined that the improvement of damping by tuning makes it possible to more rapidly increase the power output and has a favorable effect on the inertial response of the CC-VSG model over the entire network density variation range considered, which cannot be achieved by using the conventional VC-VSG structure.
