Huawei and SchneiTec Launch the World’s First TÜV SÜD-Certified Grid-Forming Energy Storage Project

Introduction


In a significant achievement for sustainable energy, Huawei Digital Power and SchneiTec have successfully commissioned the first TÜV SÜD-certified grid-forming energy storage project in Cambodia. This project marks a pivotal milestone in the country’s journey towards a greener energy future. As a leading provider of energy solutions, SchneiTec had previously developed Cambodia’s largest solar power plant, highlighting their commitment to renewable energy.

Project Overview


The newly completed energy storage system boasts a capacity of 12 MWh and includes a dedicated 2 MWh test bed for validating Huawei's Smart String Grid-Forming Energy Storage System (ESS). This system has showcased exceptional capabilities in stabilizing power grids in both off-grid settings and situations with weak grid connections, facilitating seamless integration of intermittent renewable energy sources.

The TÜV SÜD certification, recognized globally for its rigorous energy technology testing standards, confirms that Huawei's technology meets key benchmarks in the industry. This validation is more than a technical achievement; it lays a solid foundation for the expansion of energy infrastructure in Cambodia.

Key Technical Insights


The project underwent thorough testing conducted collaboratively by TÜV SÜD, SchneiTec, and Huawei Digital Power. Multiple technical capabilities of the Smart String Grid-Forming ESS were validated, showcasing the following:

  • - Grid-Forming Inertia: Huawei's technology demonstrated extraordinary inertia response capabilities, achieving an inertia time constant (Tj) range between 3 to 20 seconds, surpassing the standard requirement of 3-12 seconds. This enables faster stabilization of power grids.

  • - Voltage Ride-Through: The system effectively managed voltage fluctuations and maintained network stability during transient drops and spikes, operating within a wide voltage range of 5% to 130% of the nominal grid voltage.

  • - Overload Support and Frequency Response: The grid-forming ESS functioned stably under short-term overload conditions up to 300%, efficiently suppressing low-frequency oscillations in the range of 0.2 Hz-5 Hz.

  • - Black Start Capability: The technology allowed for rapid startups in the absence of supply under load, facilitating quick recovery of the grid after complete outages.

This independent validation abroad represents the first on-site confirmation of the ESS grid-forming technology fully compliant with international standards such as IEC, China National Standards, and the UK Grid Code, along with German VDE standards.

Looking Ahead


Achieving TÜV SÜD certification exemplifies that Huawei's grid-forming ESS technology meets globally recognized benchmarks for energy management and grid stability. This project not only signifies an essential milestone in Huawei Digital Power's technological development but also highlights a crucial moment in the evolution of energy sector innovation.

The successful collaboration between Huawei Digital Power and SchneiTec is a vital step forward in Cambodia’s transition towards renewable energies. As Cambodia continues its renewable energy roadmap, Huawei Digital Power aims to foster innovation, delivering stable, scalable, and reliable solutions to meet the rising demand for sustainable electricity and further support the development of its energy infrastructure.

Conclusion


The launch of the world’s first TÜV SÜD-certified grid-forming energy storage project in Cambodia illustrates a significant advancement in renewable energy technology. It reflects a promising future for energy stability and sustainability, setting a benchmark for similar projects globally.
