The Application of Synchronverter for the Enhancement of Power System Stability

Abstract

This paper is aimed at investigating the impact of the virtual synchronous generator in the enhancement of power system stability. The virtual synchronous generator is built and applied to enhance the transient stability margins for the power system whenever a photo-voltaic panels are added to the system. IEEE 9-bus system is chosen for investigating the effectiveness of the proposed synchronverter control scheme. The synchronverter has been connected to a single machine infinite bus system through a 208V/ 13.8kV step up transformer. The proposed scheme is verified using MATLAB® Simulink software which is used for the simulations in this study. The results demonstrates that the synchronverter enhances the behavior of the power system in transient and steady state operation.
