Transient Synchronization Stability of Grid-Forming Converter During Grid Fault Considering Transient Switched Operation Mode

IEEE Transactions on Sustainable Energy, 2023
With the increasing penetration of renewable energy generation, grid-forming (GFM) converters that simulate the dynamics of synchronous generator (SG) and actively participate in grid voltage and frequency regulation are increasingly employed.

Grid-Forming Inverter-Based Resource Research Landscape: Understanding the Key Assets for Renewable-Rich Power Systems

IEEE Power and Energy Magazine
The shift to net zero energy systems has changed the face of our power grid. Traditional large-scale synchronous generators found inside coal and natural gas plants are being replaced with inverter-based resource (IBR) technologies. This transition to an

Analytical Design of Contributions of Grid-Forming and Grid-Following Inverters to Frequency Stability

IEEE Transactions on Power Systems
Most of the new renewable generation in power systems is connected through Grid-Following inverters (GFL). The accompanying decline of fossil-fuelled synchronous generation reduces the grid inertia. As these two trends progress, instabilities become more

Torsional vibration analysis of grid-forming PMSG wind turbine

IET Conference Proceedings, 2023
In this paper, a small-signal model of a grid-forming (GFM) permanent magnet synchronous generator (PMSG) wind turbine is developed and presented, which can be utilized to study the electromechanical dynamics. The study demonstrates that there is a significant negative impact of GFM control on the torsional mode of the two-mass drive train, and ...

Cross-Forming Control and Fault Current Limiting for Grid-Forming Inverters

IEEE transactions on power electronics
This article proposes a “cross-forming” control concept for grid-forming inverters operating against grid faults. Cross-forming refers to voltage angle forming and current magnitude forming.

Grid Forming Converter Technology and Applications

2022
One of the drawbacks of the increasing use of (mostly inverter fed) renewable technologies is the reduction in transient stability of power systems with high renewable penetration. Grid forming inverters provide one solution to maintaining power system stability.
