Key Technologies for Power Conversion, Safety Management, and Grid Support in Battery Energy Storage Systems

Energy storage serves as a critical strategic technology for national development of large-scale renewable energy. However, batteries alone do not constitute an energy storage system - system-level battery management is an essential prerequisite for safe and stable operation. The integration of power electronics, cloud computing, and AI-driven digital technologies enables precise and reliable monitoring and management from individual cells to complete systems. Achieving higher discharge capacity, enhanced safety, extended lifespan, and simplified maintenance has become fundamental requirements for high-quality energy storage solutions. Moreover, to support the construction of new power systems, energy storage is evolving from being a "passive follower" of grid stability to an "active architect" of system construction. Grid-forming technologies are transitioning from single-function applications to a new phase of systematic, deep integration. This transformation centers around three key pillars: high-performance hardware, advanced grid-forming algorithms, and intelligent systems. Through progressive layering and cross-disciplinary convergence, these technologies are building comprehensive support capabilities that meet stability requirements across all scenarios, operating conditions, and time domains. This special session consequently examines the critical technologies of battery energy storage systems through three key dimensions: power conversion, safety management, and active grid support. Topics of interest include, but are not limited to:

1. High-Power-Density Converter Topologies and Advanced Control Strategies for BESS

2. Co-optimized Design of Batteries and Power Devices for Extreme Conditions

3. Digital Twin-Based Active Safety Protection for BESS Across Full Lifecycle

4. AI-Driven State-of-Health Assessment and Lifetime Prediction Models for Batteries

5. Wide-Bandwidth Stability Control for Grid-Forming Energy Storage Converters

6. Dynamic Reconfiguration Technologies for BESS in High-Penetration Renewable Energy Scenarios

7. Megawatt-Level Power Conversion Systems for Fast-Charging Battery Storage

8. Multi-Mode Operation and Active Grid Support Strategies for BESS in Weak Grids

9. Standardized Testing and Evaluation Methods for BESS in Future Power Systems
