摘要

本文提出了一种新的混合储能系统(HESS)配置，实现了电池与超级电容器(SC)的电力分流，以及多个超级电容器在直流微电网中的协同运行。电池和SC之间的功率共享是通过电池内部电阻和输出LCL滤波器的组合来实现的，LCL滤波器由SC和两个电感组成。电池电流经过补偿，使其在任何干扰下都能平稳地变化。利用PSIM仿真软件对LCL参数的影响进行了研究和评价。仿真结果表明，所提出的HESS结构具有稳定性能高、成本低、易于应用于直流微电网的特点。

A hybrid energy storage system for transient load and its multiple operation in DC microgrid

This paper presents a new configuration of hybrid energy storage system (HESS) to split the power between battery and super-capacitor (SC), and cooperative operation of multiple HESS in DC microgrid. The power sharing between the battery and the SC is achieved by means of the combination of internal battery resistance and output LCL filter, which consists of SC and two inductors. The battery current is compensated so that it smoothly changes regardless of any disturbance. The effect of the LCL parameters is investigated and evaluated by simulation with PSIM software. The simulation results prove that the proposed HESS configuration achieves high stability performance, lower cost and easy application to DC microgrid.
