Small-Signal Synchronization Stability of Grid-Forming Converters With Regulated DC-Link Dynamics
IEEE transactions on industrial electronics (1982. Print), 2023The dc-link voltage dynamics can be directly used to synchronize grid-forming (GFM) converters with ac grids. However, such control scheme is prone to unstable low-frequency oscillations (LFO), owing to the constant-power dynamics at the dc link.

Stability analysis of high-power DC grids
Conference Record 2009 IEEE Industrial & Commercial Power Systems Technical Conference, 2009During the last several years, increasing effort has been spent to advance offshore wind power. So far, only small test fields have been realized, and the electrification of offshore wind farms still remains a research topic. Currently, offshore wind farms are equipped with three-phase ac grids, some of them will be connected to the transmission grid ...
