摘　　要：为了改良直流母线电压并优化储能系统的性能,提出了一种基于混合储能系统的母线电压控制策略。在此基础上设计一种基于二阶低通滤波器原理的功率分配方法,合理配置储能系统功率。搭建混合储能系统模型,并对该模型进行Matlab仿真,分析了直流微电网混合储能系统在负荷突变情况下的运行特性,仿真结果表明该控制策略能快速控制直流侧母线电压,并延长储能系统的寿命。In order to improve the DC bus voltage and optimize the performance of the energy storage system,a bus voltage control strategy based on the hybrid energy storage system is proposed.On this basis,a power distribution method based on the principle of second-order low-pass filter is designed,and the power of the energy storage system is rationally allocated.In this paper,a hybrid energy storage system model is built and Matlab simulation is carried out to analyze the operation characteristics of the dc micro-grid hybrid energy storage system under load mutation.Simulation results show that the control strategy can quickly control the bus voltage on the dc side and extend the life of the energy storage system.
