Modeling and Analysis of Parallel VSGs with Consensus Control

In recent years, consensus control has become a research hotspot in microgrids cooperative control. When consensus control is applied to virtual synchronous generator (VSG) system, the system has more complicated dynamic performance since it has higher order. Aiming at this problem, this paper establishes a small signal state-space model, and analyzes the influence of various control parameters. Furtherly, suggestions on parameters design are given based on the model. Finally, the simulation results verifies the accuracy of model the effectiveness of the design method.
