Stability analysis of grid-following converter considering DC side dynamics
DC side dynamics are ignored in most of the research on grid-connected converter, which is dealt as a constant voltage source. In this case, the analysis result of small-signal stability is affected to some extent.

Grid–Following DVI–Based Converter Operating in Weak Grids for Enhancing Frequency Stability [PDF]
Inertia requirement is the paramount challenge in future power systems with a significant share of renewable energy generators. A promising solution to this issue is applying Distributed Virtual Inertia (DVI) concept, i.e. releasing energy preserved in the dc-link capacitors of employed power converters in the grid following a frequency disturbance ...
