Introduction

In a groundbreaking initiative for Cambodia's energy sector, Huawei Digital Power has partnered with SchneiTec to unveil the country’s maiden TÜV SÜD-certified grid-forming energy storage project. This initiative is not just a technological milestone; it heralds a significant shift towards sustainable energy solutions in a region ripe for transformation.

Project Overview

The newly commissioned project boasts an impressive capacity of 12MWh, including a vital 2MWh testbed designed specifically to validate Huawei's cutting-edge Smart String Grid-Forming Energy Storage System (ESS) technology. By integrating this innovative technology, the project has demonstrated its efficiency in stabilizing the power grid, particularly under off-grid and weak-grid conditions. Most notably, it allows for the smooth incorporation of intermittent renewable energy sources, showcasing a promising avenue for enhancing energy reliability.

Certification and Validation

The project has received authoritative certification from TÜV SÜD, a recognized leader in testing and certification within the energy sector. This certification emphasizes the project's compliance with international quality standards. In collaboration with TÜV SÜD, SchneiTec, and Huawei, a series of rigorous tests were conducted to assess the technical capabilities of the grid-forming ESS technology.

Key Technical Achievements

• - Inertia Response: Huawei’s technology exhibited remarkable inertia response performance with an inertia time constant (Tj) ranging between 3–20 seconds, surpassing the standard requirement of 3–12 seconds, thus enhancing grid stabilization.
• - Voltage Management: The system demonstrated the capability to effectively manage voltage variations, maintaining stability across a voltage range of 5% to 130% of the rated grid voltage, even during transient conditions.
• - Overload Modulation: Under stress conditions, the grid-forming ESS operated reliably under short-term overloads of up to 300% while successfully suppressing low-frequency oscillations within the 0.2Hz–5Hz range.
• - Rapid Recovery: The technology’s black start capability allows for a swift recovery of the grid post-outage, marking it as a pivotal asset for grid resilience.

This comprehensive validation underscores the project’s adherence to not only local but also international standards, including IEC, China National Standards, the UK Grid Code, and Germany’s VDE standards. Such achievements reflect Huawei’s commitment to meeting recognized benchmarks in energy management and stability.

Significance for Cambodia’s Energy Agenda

The success of the Huawei-SchneiTec partnership is a critical advancement for Cambodia's renewable energy ambitions. As the nation continues to navigate its renewable energy roadmap, Huawei Digital Power aims to further innovate by developing solutions that are not only stable and scalable but also effectively cater to the country's growing electricity demands.

This project forms the bedrock for future energy infrastructure developments, signaling a promising path forward for Cambodia in its pursuit of a greener, sustainable electricity landscape.
