摘要

针对应用混合储能平抑风浪联合发电系统功率波动的典型场景,采用二阶低通滤波法对超级电容器与锂电池功率进行初步分配,并以此为基础提出一种包括功率修正与能量管理模块的新型功率分配控制拓扑。其中,功率修正模块主要从稳定直流母线电压、补偿储能内阻损耗与功率限幅需求出发,动态调整混合储能系统的功率分配初值以提升储能稳定运行能力;能量管理模块采用一种可免于荷电状态（SOC）滞留的变滤波时间常数法,通过设置能量缓冲区来避免超级电容器过充过放。最后在Matlab/Simulink中搭建仿真模型,结果验证所设计控制策略的技术合理性。

Abstract

Aiming at the typical scenario of applying a hybrid energy storage system （HESS） to smooth the power fluctuation of a wind-wave combined power generation system, the second-order low-pass filtering method is used to initially distribute the power of supercapacitor and lithium battery, and a new power distribution control topology including power correction and energy management modules is proposed.The power correction module mainly focuses on stabilizing the DC bus voltage, compensating the energy storage internal resistance loss and power limiting requirements, and dynamically adjusting the initial power distribution value of HESS to enhance the stable operation capability of energy storage; the energy management module adopts a variable filtering time constant method, which can be exempted from the stagnation of the state of charge（SOC）, and avoids overcharge and overdischarge of supercapacitors by setting energy buffer zones. Finally, a simulation model is built in Matlab/Simulink, and the results verify the technical rationality of the control strategy designed in this paper.
