YunNeng Magic Cube | "Nuclear-Grade Energy Storage System Safety Solutions" Leads Industry Development
Published:2023-03-08
Industry Background
In 2022, the pace of domestic energy storage power station construction accelerated, marking the entry of the energy storage industry into a phase of large-scale, rapid development. Driven by this momentum, several newcomers rushed into the market, employing low-price strategies to seize市场份额, which inadvertently triggered a vicious cycle where "bad money drives out good," ultimately leading to heightened concerns over the safety of China's large-scale energy storage systems.
In 2023, during the Two Sessions, members of China's leading energy storage battery companies proposed in their "Proposal on Accelerating the High-Quality Development of Battery Energy Storage" that a safety grading evaluation system for battery energy storage systems should be established—modeled after nuclear power plant-level safety standards and based on failure probability. They also suggested incorporating this system into the bidding criteria for major projects, thereby guiding the battery energy storage industry toward high-quality development benchmarked against "nuclear-grade safety."
Energy storage system safety involves multiple technical factors, including the battery cells themselves, battery pack assembly, battery management systems, power conversion control, electrical safety design, relay protection for power systems, and power system dispatch and control. While a single-point solution can help reduce the likelihood of accidents, it cannot completely eliminate potential risks within the system. To establish a tiered safety assessment framework for energy storage systems, it is essential to tailor solutions specifically to existing power system safety standards, refine current technical approaches for energy storage systems, enhance product safety design principles, and develop a rigorous system of technical standards—thereby guiding the healthy development of the industry.
Yuneng Magic Cube's "Nuclear-Grade Energy Storage System Safety Solution"
Based on the current state of the energy storage industry, Yunneng Magic Cube, leveraging 25 years of experience in the power system sector and 15 years of expertise in grid-scale energy storage product development and engineering applications, proudly introduces its new "Nuclear-Grade Energy Storage System Safety Solution." This solution is equipped with Yunneng Magic Cube's proprietary BWS battery early-warning system, ASS active safety system, HCS high-speed control system, and EDR fault recording system. Complementing these advanced features are upgraded module-based converter systems (PCS), a refined battery management system (BMS), and an enhanced energy management system (EMS), collectively boosting the overall safety of the energy storage system. These components enable comprehensive security management across batteries, PACKs, battery clusters, personnel, equipment, the entire system, and even the power grid itself—effectively reducing the likelihood of incidents while ensuring precise accident tracing and analysis.
BWS Battery Early Warning System
By leveraging the data-driven battery warning system BWS, which relies on AI algorithms, the system uses cloud-based machine learning algorithm iterations combined with lightweight local computation and inference to deliver at least a 5-minute early warning in case of battery failures, effectively preventing fires in battery systems.
ASS Active Safety System
By leveraging IoT and artificial intelligence algorithms, the system achieves interlocking between equipment health status and operation & maintenance permissions. Additionally, it employs facial recognition and voiceprint identification to authenticate maintenance personnel, reducing accident rates by more than 3% while effectively ensuring both the safety of operations staff and the secure functioning of equipment.
HCS High-Speed Control System
Real-time Ethernet technology, featuring high synchronization and low-latency control, enables tens of thousands of nodes with latency no greater than 10 µs, reducing the system's single-frequency regulation time by more than 50 ms—and helping to prevent grid disconnection-related safety failures.
EDR Fault Recording System
Multi-source data acquisition and reliable data traceability enable synchronized fault recording across multiple data sources, along with intelligent accident recall and analysis—filling a global industry gap in the energy storage sector. This breakthrough provides comprehensive safety technology support for energy storage power plants, facilitating fault recording, accident tracing and analysis, as well as clear identification of responsibility in the event of incidents.
Modular Power Conversion System PCS
String-type multi-branch clustering control ensures rapid isolation of faulty cells, enabling non-stop, online maintenance without system downtime—and preventing malfunctioning cells from continuing to operate. This effectively achieves electrical and safety isolation, safeguarding the energy storage system from cascading fires.
Battery Management System BMS
High-density battery temperature monitoring, battery PACK connector temperature detection, and PACK-level fire suppression联动 control—comprehensively preventing battery module fires from occurring.
Energy Management System EMS
Based on the upper-level grid control and safety strategies, as well as dynamic local fault-condition operating policies, regionalized intelligent control and dispatch are implemented, enabling system-level partitioning and safety management to effectively limit the scope of incidents.
