Multisampled current control of grid-following voltage source converters

Pulse width modulation (PWM)–based current control is widely used in grid-following voltage source converters (VSCs). However, a large control delay is induced in the regular PWM process, which limits the current control bandwidth and deteriorates VSC-grid interactive stability.

Impact of Grid Faults on Grid-Following Converter Controller Operation and Phase Instability

IEEE International Conference on Renewable Energy Research and Applications
Currently, most Inverter-Based Resources (IBRs) connected to power systems use Grid Following Inverter (GFL) models. However, as the penetration of IBRs in power systems increases, concerns about inverter control issues in weak grids are growing ...

Large-Signal Stability Analysis of Grid-Following Converters Considering the Behavior of Grid-Forming Converters

International Journal of Circuit Theory and Applications
ABSTRACTThe increasing penetration of renewable energy challenges single‐converter systems to simultaneously provide transient support and rapid response. Hybrid microgrids integrating grid‐forming (GFM) and grid‐following (GFL) converters are thus essential for dual‐high power systems.

Passivity-Based Optimal State-Feedback Control for LCL-Filtered Grid-Following Converter

IEEE transactions on power electronics
As the grid incorporates more voltage-source converters (VSCs), the stability issues arising from VSC-grid interactions escalate. While passivity theory offers a promising solution, existing passivity-based controller designs primarily rely on heuristic ...

Modeling and Control of Three-Phase Grid-Following Converter via Matlab/Simulink

2024 6th International Conference on Smart Power & Internet Energy Systems (SPIES)
The integration of renewable energy sources (RES) into modern power grids has necessitated the use of grid-following (GFL) converters to ensure reliable synchronization and power exchange between distributed energy resources (DERs) and the grid.

Transient Stability Analysis Between Grid-Following DFIG-WT and Grid-Forming Converter in Electromechanical Timescale

IEEE transactions on energy conversion
Due to the transient control switch, the electromechanical dynamic of grid-following-based doubly fed induction generator-based wind turbine (GFL-DFIG) would be excited and significantly interact with grid-forming-based voltage-source converter (GFM-VSC).

Grid-Connected Converter With Grid-Forming and Grid-Following Modes Presenting Symmetrical and Asymmetrical Fault Ride-Through Capability

IEEE Journal of Emerging and Selected Topics in Power Electronics
Grid-connected converters must remain coupled to the grid during a fault. They have to control the reactive currents injected to the grid because of its limited overload capacity. In particular, grid-forming (GFM) converters ride through the fault either
