Huawei and SchneiTec Commission World’s First TV SD-Certified Grid-Forming Energy Storage Project

SHANGHAI, June 16, 2025 /PRNewswire/ — Huawei Digital Power, in collaboration with SchneiTec, has successfully commissioned Cambodia’s first-ever TÜV SÜD-certified grid-forming energy storage project, marking a key milestone in the country’s transition toward a sustainable energy future. As a leading energy solutions provider in the region, SchneiTec previously developed Cambodia’s largest solar power plant.

This newly completed 12MWh energy storage project includes a 2MWh testbed dedicated to validating Huawei’s Smart String Grid-Forming ESS technology. The system has demonstrated its exceptional capabilities in stabilizing the grid in both off-grid and weak-grid scenarios by facilitating the seamless integration of intermittent renewable energy sources. The project has received authoritative certification from TÜV SÜD, marking Cambodia’s first grid-forming ESS deployment and laying a strong foundation for future capacity expansion and large-scale energy infrastructure development.

The project was jointly tested by TÜV SÜD, SchneiTec, and Huawei Digital Power. TÜV SÜD — renowned globally for its rigorous standards in energy technology testing and certification — verified the key technical capabilities of Huawei’s Smart String Grid-Forming ESS, including inertia response, high/low voltage ride-through, frequency support, and overload performance.

Key Testing Highlights:

  • Grid-forming inertia: Huawei’s grid-forming technology demonstrated exceptional inertia response performance, achieving an inertia time constant (Tj) range of 3–20 seconds — well beyond the standard requirement of 3–12 seconds — enabling faster grid stabilization.
  • Low/high voltage ride-through: The system effectively managed voltage fluctuations, maintaining grid stability during short-term voltage dips and surges. It remained operational across a wide voltage range from 5% to 130% of the rated grid voltage.
  • Overload and frequency support: The grid-forming ESS operated stably and reliably under short-term overload conditions of up to 300%, and effectively suppressed low-frequency oscillations across the 0.2Hz–5Hz range.
  • Black start: The technology enabled rapid black start capability under load, enabling efficient grid restoration following a complete outage.

This independent verification of Huawei’s grid-forming ESS technology represents the first overseas on-site validation of the system in full compliance with international standards, including IEC, China National Standards, the UK Grid Code, and Germany’s VDE standards.

Obtaining TÜV SÜD certification demonstrates that Huawei’s grid-forming ESS technology meets globally recognized benchmarks for energy management and grid stability. This milestone not only marks a major achievement in Huawei Digital Power’s technological development journey, but also represents a landmark moment in the evolution of energy sector innovation.

Huawei Digital Power’s successful collaboration with SchneiTec signals a significant step forward in Cambodia’s renewable energy transition. As Cambodia’s renewable energy roadmap progresses, Huawei Digital Power will continue to drive innovation — delivering stable, scalable, and reliable solutions to meet the country’s growing demand for sustainable electricity, and supporting the advancement of its energy infrastructure.
