Frequency Quality Assessment of GFM and GFL Converters and Synchronous Condensers
CoRRThis paper compares the impact of different conventional and emerging technologies and control strategies on frequency quality. We study, in particular, the long-term dynamic performance of grid-forming (GFM) and grid-following (GFL) inverter-based resources (IBRs) as well as conventional synchronous machines.

Transient Stability of GFL Converters Subjected to Switching of Droop-Controlled GFM Converters
IEEE Transactions on Energy ConversionIntegrating grid-forming converters (GFMCs) into grid-following converter (GFLC)-dominated power systems enhances the grid strength, but GFMCs' current-limiting characteristic triggers dynamic switching between constant voltage control (CVC) and current limit control (CLC).

Siting and Sizing Method of GFM Converters Based on Genetic Algorithm
InventionsThe rising integration of renewable energy sources has resulted in a diminished capacity for voltage support within the system, which is characterized by low inertia and a reduced short circuit ratio (SCR). In order to improve grid strength and enhance the capacity for renewable energy integration, an initial analysis was conducted on the grid support ...
