摘要

在园区能源互联网中，为了实现储能元件充放电过程的实时控制，以2 V、200 Ah的阀控式铅酸蓄电池为研究对象，根据能源系统供给侧环境、实验数据和现有数据，建立兼顾电、热、非线性行为和温度估计的非线性动态等效电路模型。通过该模型研究不同放电速率对储能设备容量的影响，电池的非线性参数与电流和开路电压有关的函数，电池温度对内部参数的影响。该模型结果与实验结果完全匹配，为改善储能配置提供一定的参考价值。

Abstract

In the park energy Internet

in order to realize the real-time control of the charging and discharging process of the energy storage elements

the 2V

200 Ah valve-regulated lead acidbattery is taken as the research object. According to the supply side environment

experimental data and existing data of the energy system

a nonlinear dynamic equivalent circuit model is established

which takes into account electricity

heat

nonlinear behavior and temperature estimation. Through the model

the influence of different discharge rates on the capacity of energy storage equipment

the function of the nonlinear parameters of the battery related to the current and open circuit voltage

and the influence of the battery temperature on the internal parameters are studied. The model results match the experimental results completely

which provides a certain reference value for improving the energy storage configuration.
