摘要
在含有脉冲负载的微电网中,储能设备荷电状态受到负载功率变化影响较大。为了准确估算脉冲负载下储能电池的荷电状态,本文提出了一种基于能量积分的动态荷电状态定量计算方法,可实时在线评估储能电池的动态荷电状态,并选取了三种在微电网储能中被广泛应用的储能电池作为测试对象,在获取其充放电特性的基础上,基于能量积分计算储能电池在不同负载功率下的动态荷电状态。
In a micro-grid with pulsed loads,the state of charge of energy storage devices is affected by changes in load power.In order to accurately estimate the state of charge of the energy storage battery under pulse load,a quantitative calculation method of dynamic state of charge based on energy integration is proposed,with which the dynamic state of charge of the energy storage battery online can be evaluated in real time.Taking three kinds of energy storage batteries widely used in micro-grid energy storage as the test object,the dynamic charge state of energy storage batteries under different load powers is calculated using the method of energy integration on the basis of obtaining their charge and discharge characteristics.
