英文摘要	For analyzing the problem of frequent wideband oscillations in grid-connected renewable energy generation systems, an analysis method based on small-world networks and fast-slow dynamics is proposed. A direct-driven permanent magnet synchronous generator (DPMSG) was chosen as an example to discuss the process of bursting oscillations in a single system with both alternating large-amplitude and micro-amplitude oscillations due to the multi-timescale coupling effect introduced by the disturbance. Meanwhile, a complex network consisting of multiple DPMSGs connected to the grid was selected to investigate the process of bursting oscillations in generation nodes spreading among the system nodes. The results showed that the bursting oscillations created by the power generation nodes in grid-connected renewable energy generation systems can lead to oscillation instability of the entire system. Our simulation verified the feasibility and effectiveness of the method proposed in this paper. © 2022 Author(s).
