摘要

本文研究了由云层阴影引起的日间太阳辐射变化对铅酸蓄电池储能系统使用寿命的影响。模拟采用大河州微电网数据，采用均衡周期为7天的Schiffer模型表示蓄电池组的充放电过程。结果表明，短时间的间歇对电池的使用寿命有显著影响。忽略这一影响会导致在估计电池组的使用寿命时出现严重误差，从而在预测微电网的运维成本时也会出现严重误差。

Investigating the Impact of Solar Intermittency on the Storage System Lifetime in PV-Based Isolated Microgrids

This article investigates the impact of daytime solar radiation variation caused by cloud shadows on the useful life of the storage system based on lead-acid batteries. The simulations are carried out using data collected from the microgrid of Ilha Grande - MA, with the charging/discharging process of the battery bank represented by the Schiffer model with an equalization period of seven days. The results show that short-duration intermittence has a significant impact on battery useful life. Ignoring this effect leads to gross errors in estimating the useful life of the battery banks and consequently in forecasting the O&M costs of the microgrid.
