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 ...

Envelope-based Modeling for Single-Phase Grid-Following and Forming Converters
2022 IEEE 23rd Workshop on Control and Modeling for Power Electronics (COMPEL), 2022The study of the interaction with the grid, including synchronization, controller design and stability assessment for 1f grid-following (GFL) and grid-forming (GFM) power converters requires an efficient modeling tool to design universal grid-connected converters considering the different grid scenarios.

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.He, Shan; id_orcid 0000-0001-6789-8271 +1 more

ABSTRACT The 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.
