As renewable energy penetration continues to rise, power grids are facing new stability challenges. Low inertia, weak-grid conditions, dynamic voltage stability and the ability to restore the system after major blackouts are placing greater demands on the transmission grid.
For the transmission side, Grid-Forming (GFM) technology is valuable because it enables renewable energy to connect to the grid and more besides. More importantly, it enables renewable energy resources to actively support and stabilise the grid.
To enhance grid stability, DoGo is focusing on key grid-forming solutions:
-
Virtual Inertia + Damping: Safeguarding Frequency Stability
Grid-Forming control simulates the inertia and damping characteristics of synchronous generators, enabling the system to respond rapidly to power disturbances, reduce the rate of change of frequency (RoCoF) and improve the grid’s ability to withstand large-scale renewable integration and sudden power disturbances.
-
Fast reactive power response: strengthening dynamic voltage support
Grid-forming control can provide rapid dynamic reactive power support. Under weak-grid conditions and during fault disturbances, it improves voltage stability at critical nodes. Strengthening voltage support also improves the equivalent short-circuit ratio (SCR), enhancing the stable operation of renewable energy transmission corridors.
-
Black-start power supply: enhancing system restoration capability
Grid-forming power sources can do more than simply maintain stable operation. Under specific system conditions, they can establish voltage and frequency at the receiving end of the grid. This provides a new source of support for black-start operations and system restoration following major blackouts.
