Grid-Forming BESS

Storage that supports the grid instead of depending on it. VSG-based grid-forming control, certified in China’s first batch by CPRI in 2023 — and running today at GWh scale in Xinjiang.

The Problem

Almost every inverter on the grid today is grid-following: it measures the grid’s voltage and frequency, then synchronises to them. As coal and gas retire and renewables scale, system inertia falls, grids get weaker — and a fleet of grid-following inverters in a weak grid can actively destabilise things.

The Solution

Grid-forming inverters establish voltage and frequency references themselves, provide synthetic inertia, and damp oscillations — behaving more like a synchronous machine than a passive converter. Soaring’s GFM control delivers inertia and damping equal to or better than a conventional synchronous machine, with full adaptation to strong grids, weak grids and high-renewable nodes.

What GFM Enables

• Full-process voltage and frequency support
• Synthetic inertia
• Weak-grid connection
• Black start
• Sub-synchronous oscillation damping
