摘要

在电动/混合动力汽车和孤岛直流微电网等系统中，混合储能系统(HESS)技术被用于增强电池。在直流微电网的情况下，必须平衡源和负载之间的能量流，以照顾一个无情的直流电网电压。能量储存被用来平衡源和负载之间的任何不平衡。在所有混合储能系统中，以超级电容器和电池为基础的组合储能是控制功率不平衡的最佳方案。本文介绍了HESS的建模、双向变换器的设计、控制器的设计、稳定性分析和仿真，以及光伏发电和负荷需求阶跃变化的实验结果。包括传统控制方案的研究结果以及所提出的控制方案。

HESS-Based Bi-Directional DC-DC Converter with Adaptive Control Strategy

In systems like electric/hybrid vehicles and islanded DC microgrids, hybrid energy storage system (HESS) technologies are employed to augment the batteries. In case of a DC microgrid, the flow of energy between the source and the load must be balanced so as to take care of a relentless DC grid voltage. Energy storage is utilized to balance out any imbalances between the source and the load. To control the imbalance power, supercapacitor and battery-based combination storage is the best solution among all hybrid energy storage systems. This paper presents the HESS modelling, design of bidirectional converter, controller design, stability analysis and simulation as well as experimental findings for a step change in PV generation and load demand are presented. The outcomes of the study of the conventional control scheme along with the proposed control scheme were included.
