Sensitivity Analysis and Small-Signal Stability of Grid Following Converters

TecnoLógicas, 2022
This article presents a small-signal study, based on a sensitivity analysis, of a voltage source converter (VSC) operating as a grid-following device. This type of operation is standard for integrating distributed energy resources directly into a primary

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

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)

External Inertia Emulation Controller for Grid-Following Power Converter [PDF]

IEEE Transactions on Industry Applications, 2021
The advent of renewable energy has posed difficulties in the operation of power systems whose net inertia is becoming critically low. To face such challenges, grid-forming power has been one of the potential solutions pursued by the industry and research community. Although promising, grid-forming power converters are still immature for mass deployment

Synchronous Fault Compensator for Voltage Sensorless Grid-Following Power Converters

2021 IEEE 12th International Symposium on Power Electronics for Distributed Generation Systems (PEDG), 2021
During the last decade, the penetration of grid-connected RES systems has been in constant increase, forcing those systems interfaced to the electrical grid to improve and design new advanced controllers to maintain the power converter under control. The most extended control for grid-tied inverters is the so-called grid-following control.

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

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 ...

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

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.

A new transient phenomenon caused by active current dynamics of grid-following converters during severe grid faults [PDF]

Frontiers in Energy Research
Existing transient stability analysis of grid-following (GFL) converters mainly focuses on the dynamics of the phase-locked loop (PLL), while current loop dynamics are usually neglected due to their faster response than PLL. However, this article reveals

Transient Stability Enhancement with High Shares of Grid-Following Converters in a 100% Converter Grid

2020 IEEE PES Innovative Smart Grid Technologies Europe (ISGT-Europe), 2020
With increasing shares of power electronics-based generation in power grids, grid-following converters may become unstable during faults, resulting from a loss of phase-locked loop (PLL) synchronism. Even when current grid code low voltage ride through (LVRT) requirements are met, PLLs may still become unstable under high shares of grid-following ...
