Huawei Digital Power's ESS Safety Forum in Shanghai

On June 12, 2025, Huawei Digital Power organized a pivotal forum in Shanghai centered around safety in the deployment of energy storage systems (ESS) and network formation. The event gathered a diverse group of attendees, including clients, partners, insurance providers, and certification organizations from the photovoltaic and energy storage sectors. The primary goal was to discuss and share insights on the evolving trends and applications related to network formation technologies, business practices, and the development of a secure ecosystem surrounding ESS.

Opening Remarks and Industry Insights

The forum commenced with an insightful address from Steven Zhou, President of Huawei Digital Power's Smart PV+ESS product line. Zhou emphasized the increasingly vital role ESS plays in integrating renewable energy into the grid as global energy transformation accelerates. He highlighted that while this presents unprecedented opportunities, it also introduces significant challenges. The popularity and advanced capabilities of grid-forming ESS technologies are paramount for network stability, making safety a non-negotiable priority for sustainable growth in the industry.

In line with these priorities, Huawei recently launched its FusionSolar 9.0 Smart PV+ESS solution, designed to incorporate grid-forming capabilities across all scenarios. The holistic integration of these technologies is aimed at achieving comprehensive applications, reinforcing the commitment to high safety standards necessary for network reliability.

Establishing Safety Standards

Huawei Digital Power has proposed four critical safety standards for ESS: non-combustibility, non-explosiveness, non-propagation, and harmlessness. The systematic approach to the architecture of grid-forming solutions enhances system reliability. In partnership with a myriad of stakeholders, Huawei aims to innovate continuously while promoting the adoption of these safety standards, thus allowing all participants in the value chain to benefit from technological advancements and contribute to a sustainable future.

Business Strategies and Technical Challenges

Key speakers from industry-leading companies shared their perspectives on how grid-forming technology, paired with a unified standards approach, can foster investments in renewable energy. Robert Liew from Wood Mackenzie and Patrick Zank from VDE provided valuable insights on market trust and the necessity of consistent standards to promote the wide application of these advancements.

Additionally, Vannsith Ith from SchneiTec and Billy Qiu from TÜV SÜD discussed the first ESS project undertaken in Cambodia, showcasing empirical tests of Huawei’s PV+ESS system in alignment with Public-Private Partnership (PPP) standards. This pivotal testing lays a foundation for creating stable and reliable smart grids, further demonstrating the technology’s growth potential in Southeast Asia.

Advanced Technological Framework

Chen Danqing, Technical Director of Huawei Digital Power’s ESS division, identified four primary technical challenges for the large-scale application of grid-forming technology. These challenges include maintaining stability during parallel operation of multiple devices, mitigating broadband oscillations, providing robust support during overloads, and ensuring device safety and reliability. In addressing these issues, Huawei proposes an innovative “intelligent grid-forming ESS” technological process. This framework encompasses network-forming capabilities throughout the energy production, transmission, distribution, and consumption processes, thereby redefining the essential standards for grid-supporting capabilities.

Crucially, the ESS designed for network formation is expected to maintain operational integrity under diverse conditions for its entire lifespan, delivering consistent support to energy systems while meeting future business model demands. The “intelligent grid-forming ESS” strategy has undergone rigorous empirical testing, confirming its effectiveness across various projects, including those that reach gigawatt levels.

Strengthening Safety Ecosystems

The safety of ESS projects remains a focal point of discussion, with Chen Weipeng from Munich Re addressing the need for comprehensive security across the entire lifecycle of ESS products. Steve Zheng, head of Huawei Digital Power's ESS business division, highlighted three notable characteristics of ESS systems: high energy density, voltage, and current. Throughout their lifecycle, challenges such as electrochemical inconsistencies and network uncertainties could pose significant safety risks.

As a solution, Huawei introduced a groundbreaking safety system that integrates the
