Abstract: In response to the nonlinear, strongly coupled, and time-varying synchronous oscillation phenomena in DC microgrids, traditional methods cannot accurately describe the characteristics of synchronous oscillations. Based on the idea of synchronous control and finite time theory, this paper proposes an effective method for analyzing the synchronous oscillation characteristics of microgrids and a finite time projection synchronous control method. Firstly, establish a dynamic model of the DC microgrid and analyze its synchronous oscillation characteristics. Then, a small world network model is established using complex network theory to analyze node synchronization characteristics. A finite time projection synchronization control method is proposed to quickly achieve synchronization of microgrid small world network nodes, avoid system oscillation, and suppress the oscillation state of the microgrid within a limited time, and quickly achieve complete synchronization. Finally, a DC microgrid simulation experimental platform based on MATLAB/Simulink software and far-width controller is built to verify the effectiveness of the proposed method. The experimental results show that the proposed method can achieve synchronization of all nodes in the microgrid more quickly and has better adaptive regulation capability.
