摘要/Abstract

摘要： 锂离子电池储能装置是目前实现风光等新能源波动平抑的主流支撑。相比其他锂离子电池,磷酸铁锂（lithium iron phosphate,LFP）电池在安全性、使用寿命、高温性能与容量上具有综合性的优势。基于此,提出采用314 A·h磷酸铁锂储能电池的工商业储能装置。针对工业化应用的场景,提出基于电池温度的制冷策略,相较于基于回水温度的制冷策略,能提高储能装置效率0.6%。在不同温度的工况下,应用基于电池温度的制冷策略的储能装置均能达到89%以上高能量转换效率,在配电网削峰填谷与新能源平滑消纳的场景有较好的应用前景。

Abstract: Lithium-ion battery energy storage systems are currently the mainstream support for mitigating fluctuations in renewable energy sources such as wind and solar power.Compared with other lithium-ion batteries, lithium iron phosphate(LFP) batteries offer comprehensive advantages in terms of safety, service life, high-temperature performance, and capacity. This paper presents the structure of an industrial and commercial energy storage system using 314 A·h LFP energy-storage cells. For industrial application scenarios, a cooling strategy based on cell temperature is proposed, which improves the efficiency of the energy storage system by 0.6% compared with a cooling strategy based on return-water temperature. Under operating conditions at different ambient temperatures, the energy storage system employing the cell-temperature-based cooling strategy can achieve a high energy conversion efficiency of more than 89% and has good application prospects in the scenarios of peak shaving and valley filling in the distribution network and smooth consumption of new energy.

Key words: lithium iron phosphate(LFP), energy storage battery, commercial and industrial energy storage device, battery cooling, battery thermal management
