电化学储能产业发展对安全标准的需求

Demand for safety standards in the development of the electrochemical energy storage industry

储能作为新型电力系统的关键组成,市场规模取得了快速增长。在储能产业发展的同时,国内外储能项目事故也在不断发生,大多数是锂离子电池储能事故,引起了社会对储能安全的关切。储能产业亟需明确储能安全标准要求,提升储能产品和项目建设的准入门槛,避免恶性事故再度发生。本工作回顾了近两年国内外储能项目事故情况,统计了事故发生时储能项目所处的状态和储能技术类型,从事故角度分析了相应阶段对储能安全标准的需求。对电力储能系统安全相关标准,本工作重点梳理了主要的IEC标准、美国标准和国内现有的国家标准、地方标准,简要分析了相关标准的要求和特点,最后从储能项目全生命周期的角度总结了设计建设、运输、运维、消防安全、应急救援和退役回收等各阶段储能安全标准有待进一步解决的问题,并对下一步相关工作的开展给出建议,以期推动国内相关标准的完善,为储能产业安全健康发展奠定基础。

As a key component of new power systems,energy storage has achieved rapid growth in the market.Simultaneously,as the energy storage industry is developing,energy storage accidents are occurring regularly,the majority of which are lithium-ion battery energy storage accidents,raising public concerns about the safety of energy storage.The energy storage industry urgently needs to clarify the energy storage safety standards,improve the requirements for energy storage systems,and avoid vicious accidents.This study examines energy storage project accidents over the last two years,as well as the current state of energy storage accidents and the various types of energy storage technologies.This study focuses on sorting out the main IEC standards,American standards,existing domestic national and local standards,and briefly analyzing the requirements and characteristics of each standard for energy storage safety.Finally,from the perspective of the whole life cycle of the energy storage project,this study summarizes the issues to be further solved in the energy storage safety standards at various stages,such as design and construction,transportation,operation and maintenance,and emergency rescue and decommissioning,and provides relevant suggestions for the development of related work in the next step to promote the enhancement of relevant standards and lay a foundation for the safe and healthy development of the energy storage industry.
