摘　　要：为在电网仿真中精确反映铅酸电池储能的动态特性,提出描述铅酸电池储能直流侧运行特性的数字仿真模型。该模型适用于单体元件及由若干单体元件串联形成的电池包模块。以实际电池包模块及单体元件的恒流充放电运行数据为基础,采用改进的遗传算法辨识出模型参数,并对模型进行了有效性检验。结果表明,模型仿真数据与实际储能运行数据及特性相吻合,误差不大于5%,且对由单体元件串联而成的电池包而言,可在一定程度上忽略单体元件之间的差异性。In order to accurately reflect the dynamic characteristics of lead-acid battery storage for power grid simulation,a digital simulation model was proposed to describe the DC-side performance characteristics of leadacid battery storage. The model was suitable for a single element or a battery pack module formed by several single elements in series. Based on the operating data of constant current charge and discharge of the actual battery pack module and single elements,an improved genetic algorithm was used to identify the model parameters,and the validity of the model was tested. The results show that the simulation data of the model coincide with the running data and characteristics of the actual battery storage,with the error not more than 5%. And to a certain extent,the difference between the single elements can be ignored in the battery pack formed by single elements in series.
