Sungrow’s Grid-Forming Solution for Stable and Resilient Power Systems

As renewable energy penetration continues to rise, modern power systems are increasingly challenged by reduced system inertia, voltage instability, and frequency fluctuations. To address these evolving grid requirements, Sungrow has developed advanced grid-forming (GFM) solution—an innovation designed to transform energy storage systems into active grid stabilizers.

Operating as a True Grid Stabilizer
Unlike conventional grid-following inverters that depend on an existing grid signal, Sungrow’s grid-forming solution operates as a voltage source, enabling it to independently regulate voltage and frequency. This allows the system to function reliably even in weak grid conditions or in the absence of traditional generators, while delivering essential capabilities such as inertia support and black start functionality.

Ultra-Fast Response for Voltage and Frequency Control
A key strength of Sungrow’s GFM solution is its ultra-fast dynamic response. With microsecond-level voltage control and response times below 100 microseconds, the system ensures rapid stabilization of grid conditions and provides flexible inertia support to manage sudden frequency variations.

Enhanced Stability Through Intelligent Grid Support
Sungrow’s grid-forming solution further enhances system performance through oscillation damping and impedance reshaping, ensuring stability across a wide frequency range. With the ability to operate across a broad SCR range and withstand large phase angle variations, the system delivers reliable performance even in complex and weak grid environments.

Beyond stability, the solution supports high-value applications such as frequency control, system strength services, and black start operations—enabling more resilient and future-ready power systems.

Building on its global expertise, Sungrow is driving the adoption of grid-forming solution to enhance grid stability and support the transition to cleaner energy systems.
