Power Oscillation Suppression Method for Multi-VSG System Based on Consensus Center of Inertia
Virtual synchronous generator (VSG) provides inertia support to the power system by simulating the rotor equation of synchronous generator, which also introduces power oscillation into the system. In this paper, the active power oscillation problem of multi-VSG system is studied. Firstly, the mechanism of active power oscillation in multi-VSG system is analyzed. Then, a power oscillation suppression method for multi-VSG system based on consensus center of inertia (COI) is proposed. The method can suppress the oscillation effectively and make the frequency of each unit converge to the same value, which facilitates the aggregation. Finally, the effectiveness of the proposed method is verified through simulations on the MATLAB/Simulink platform.
