Voltage Sensorless Grid-Forming Power Converters

2020 IEEE 21st Workshop on Control and Modeling for Power Electronics (COMPEL), 2020
During the years, synchronization systems in power converter control has been mainly used for estimating the phase angle and the magnitude of the grid voltage, this estimated information is usually used for droop control strategies to ensure power sharing among power converters.

AC-Side Impedance-Based Stability Assessment in Grid-Forming Modular Multilevel Converters

IEEE Access
Grid-forming converters can emulate the behavior of a synchronous generator through frequency droop control. The stability of grid-forming modular multilevel converters can be studied via the impedance-based stability criterion. This paper presents an ac-

Oscillation Suppression of Grid-Following Converters by Grid-Forming Converters with Adaptive Droop Control

Energies
The high penetration of renewable energy sources (RESs) and power electronics devices has led to a continuous decline in power system stability. Due to the instability of grid-following converters (GFLCs) in weak grids, the grid-forming converters (GFMCs)

Stability enhancement strategies for a 100% grid‐forming and grid‐following converter‐based Irish power system

IET Renewable Power Generation, 2022
With increasing shares of wind and/or solar power in many power systems, the possibility of a 100% power converter‐based system becomes more likely. Consequently, the dynamic response of the Irish transmission systems with 100% (grid‐following and grid ...

Adaptive model predictive control for grid‐forming converters to achieve smooth transition from islanded to grid‐connected mode

IET Generation, Transmission & Distribution, 2023
One of the main capabilities of grid‐forming converters is the ability to operate in both islanded and grid‐connected modes. The grid‐forming converters work autonomously and behave as an AC voltage source when they are isolated from the bulk power ...
