随着中国“双碳”目标的提出,面对高比例可再生能源和波动性电力负荷带来的挑战,储能系统在电网中发挥着举足轻重的作用,储能技术是迫切需要突破的瓶颈。通过电池高效的控制管理系统对储能电池单元进行有序控制是未来储能应用大规模推广的关键。目前,储能系统建模技术的研究远远滞后实际工程需要。从电池系统、功率转换系统及电池管理系统3个方面入手,介绍了国内外电化学储能系统建模技术研究现状和发展趋势,分析了锂电池储能系统数据驱动建模技术需求;在此基础上,提出了基于数据驱动的锂电池储能系统建模技术路线,为锂电池储能系统建模技术研究的发展提供思路参考。

With China's targets for"carbon peak and carbon neutrality"being set,in view of the increased share of renewable energy and the challenge brought about by the fluctuating power load,the energy storage system plays an essential role in the power grid and the energy storage technology becomes a bottleneck that needs to be broken through urgently.Orderly control of energy storage battery units through an efficient battery control and management system is the key for large-scale energy storage applications in the future.Currently,the research on techniques for modeling the energy storage system lags far behind the actual engineering needs.Starting from three aspects of battery systems,power conversion systems and battery management systems,this paper introduces the research status and development trend of modeling techniques for electrochemical energy storage systems both at home and abroad,and analyzes the data-driven modeling technical requirements for the lithium battery energy storage system.On this basis,a data-driven technical route for modeling the lithium battery energy storage system is proposed,providing ideas and references for the development of techniques for modeling the lithium battery energy storage system.
