Grid Forming impact on DC-link voltage control

The demand for grid-forming (GFM) inverters is now the top priority of electric utilities as more and more IBRs are connected to the grid. However, there are still large barriers to preventing the actual deployment of GFM inverters in the grid. For example, the existing R&D on GFM inverter technologies is mainly based upon the assumption of a constant DC source or stable DC link, which is not feasible for todayís IBRs (such as wind and solar) that typically rely on the grid to provide a stable DC-link voltage. Also, unlike a traditional synchronous generator that outputs the power to the grid only, a GFM inverter based upon batteries requires the inverter to have bidirectional power flow capability, which has not been well explored in the existing GFM research. This panel brings experts from industry and academia to discuss the current development in GFM inverter technologies and the effect of GFM invertera on the dc-link voltage control associated with conventional storage and generation resources.
