报告内容 Massive electrochemical energy storage is an enabling technology that smoothes and firms intermittent and ramping renewable energy resources into utility electric grids. For large-scale renewable energy storage at MWh level, multi-cell Lithium-Ion battery systems are still one of the most cost-effective, feasible solutions for ubiquitous deployment. However, design deficiencies in current multi-cell battery systems impede them in large-scale renewable energy storage, including 1) monolithic design with fixed cell string structure; 2) lack of an efficient method to utilize the cell state variation for energy conversation efficiency; and 3) reliance on engineering design heuristics and lack of a systematic, holistic design with dynamic power management and time-varying source/load conditions. This talks will focus on an ambitious, paradigm-shifting design for large-scale battery systems for renewable energy storage, inspired by the concept of Energy Internet, especially on how to seamlessly integrate information and energy flows in such systems.
