**基于Matlab Simulink与PSCAD仿真的PV阵列与锂离子电池储能系统研究**,基于PV光伏阵列与锂离子电池系统的Boost DCDC变换器及双向DCDC变换器控制模型仿真分析,PV光伏阵列+Boost DCDC变器+负载+双向DCDC变器+锂离子电池系统Matlab Simulink，PSCAD仿真模型模型主要包括以下几个部分：PV光伏阵列、Boost DC DC 变器、负载Load、双向DC DC变器、锂离子电池模型、PV侧控制模块、锂离子电池侧控制模块以及观测模块。PV控制模块采用最大功率点跟踪算法MPPT，具体是“扰动观察法”系统的工作状态主要由输入参数辐照度决定：当辐照度较小以至于不能满足负载功率需求时，锂离子电池会进行输出，SOC逐渐降低；当辐照度较大使得光伏阵列输出功率高于负载需求功率时，锂离子电池会将多余功率进行回收，相当于对电池进行充电，SOC升高；下图模拟结果展示，可以发现整个过程中，负载电压能够稳定在设定值，锂离子电池也能够很好地协同工作。,核心关键词：PV光伏阵列;
