Quantitative Parameter Conditions for Stability and Coupling in GFM–GFL Converter Hybrid Systems From a Small-Signal Synchronous Perspective

IEEE Transactions on Sustainable Energy
With the development of renewable energy sources, power systems are gradually evolving into a system comprising both grid-forming (GFM) and grid-following (GFL) converters. However, the dynamic interaction between the two types of converters, especially low-inertia GFM converters and GFL converters, remains unclear due to the substantial differences in

Frequency Modulation Control of Grid-Forming Converter Based on LADRC-MI [PDF]

The increasing proportion of new energy in the power system leads to a decrease in system inertia and weakens the frequency stability of the system. The use of grid-forming (GFM) control for inverters is an effective method to improve frequency stability
