Grid–Following DVI–Based Converter Operating in Weak Grids for Enhancing Frequency Stability [PDF]

IEEE Transactions on Power Delivery, 2021
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 ...

Analysis of transient characteristics and fault ride-through control of hybrid grid-tied converters with grid-following and grid-forming

Frontiers in Energy Research
When the Grid-Following (GFL) and the Grid-Forming (GFM) converters are hybrid-connected to the grid, they are coupled through the grid impedance. During grid faults, the transient characteristics of the two converters become more complex due to this ...
