Active Power Oscillation Damping Based on Acceleration Control in Paralleled Virtual Synchronous Generators System

Although the virtual synchronous generator provides a grid-friendly operational mode for power converters, it may also introduce disadvantages similar to traditional such as oscillation in parallel due large inertia. This article proposes an additional damping strategy suppress oscillation. After analyzing relationship between output and angular acceleration, is designed by acceleration control with disturbance compensation. Small-signal analysis applied study stability of proposed method. Finally, experiments are carried out verify auxiliary
