摘要:

作为支撑智能电网和能源转型发展的关键技术,储能受到广泛关注,其中以锂离子电池为代表的电池储能成为大规模储能的首选储存载体之一。然而随着电池储能应用规模逐渐增加,暴露出储能系统在质量和安全方面存在诸多问题和风险,电池储能系统作为电气设备整机产品目前还不成熟,储能电站的整体安全与质量状态存在不确定性,导致目前大量已建储能电站利用率偏低。由于设备整机产品还处于不成熟、不断迭代发展过程中,为提升现阶段锂离子电池储能电站的应用水平,以安全高质量应用为导向,围绕储能用锂离子电池这个核心部件开展综合性能评价显得尤为重要。本文主要梳理了国内储能锂离子电池相关标准的最新进展,对锂离子电池储能核心标准的重要内容和该标准对行业发展的作用进行了详细分析。结合电池储能特性评价和检测技术研究积累,提出了涵盖型式试验、等级评价、到货抽检、并网检测及运行考核检测的电池储能全流程检测评价整体解决方案,通过对各个环节的详细分析表明该方案可以实现对投运的涉及电网运行的电网侧、电源侧、用户侧储能设备全链条全环节闭环管理,对于提升电池储能设备投运前的标准化规范化水平、提高储能电站运行可靠性、降低储能电站安全风险具有重要意义。

Abstract:

Energy storage has attracted considerable attention as a key technology enabling the development of smart grids and energy transformation, with battery energy storage represented by lithium-ion batteries becoming one of the preferred storage carriers for large-scale energy storage. However, with the gradual increase in the scale of battery energy storage applications, new challenges and risks in the quality and safety of energy storage systems have emerged. The battery energy storage system is not yet mature as a complete electrical equipment product, and there is uncertainty in the overall safety and quality status of energy storage power stations, resulting in low utilization rates of many existing energy storage power stations. Due to the immaturity and continuous iterative development process of the entire equipment product, it is particularly important to conduct a comprehensive performance evaluation around the core component of lithium-ion batteries for energy storage to improve the application level of lithium-ion battery energy storage power stations at the current stage, guided by safe and high-quality applications. This research reviews the latest progress of domestic standards related to energy storage of lithium-ion batteries. It provides a detailed analysis of the core standard for lithium-ion battery energy storage and its role in industry development. Based on the evaluation of battery energy storage characteristics and research accumulation of testing technology, a comprehensive solution has been proposed for the full process testing and evaluation of battery energy storage, including testing type, evaluation level, sampling arrival, testing grid connection, and operation assessment testing. It is demonstrated through detailed analysis of each link that the scheme can achieve closed-loop management of the entire chain of energy storage equipment on the grid side, power supply side, and user side involved in grid operation, which is of great significance for enhancing the standardization level of the battery energy storage equipment before the operation, improving the operation reliability of the energy storage power station, and reducing the safety risks of the energy storage power station.

Key words: lithium ion batteries for energy storage, comprehensive performance, energy storage standards, overall solution
