Research on Synchronization Control of Distributed Generation Based on Second-Order Unified Model
The existing grid connection controls of distributed generation inverters are mainly classified into the grid-following (GFL) control and the grid-forming (GFM) control. In this paper, with the multi-timescale separation method, the second-order unified models of GFL and GFM synchronization control...

| description | The existing grid connection controls of distributed generation inverters are mainly classified into the grid-following (GFL) control and the grid-forming (GFM) control. In this paper, with the multi-timescale separation method, the second-order unified models of GFL and GFM synchronization control are established. Based on the unified models, the small-signal stabilities of GFL and GFM control are analyzed, pointing that GFL control is compatible with strong grid, while weak grid can improve the damping ratio of GFM control. Besides, the transient stabilities of GFL and GFM are analyzed, and a general stability-enhanced method is proposed to enhance the synchronization stability. Finally, these findings are corroborated by experimental tests. |
