中文摘要

本文探讨了混合交直流微电网中双向接口变换器(IFC)的并联运行问题。随着可再生能源规模的扩大,IFC作为交直流子系统间的关键互联设备,在电网电压不平衡故障下的稳定控制至关重要。研究旨在提升系统在复杂电网环境下的运行可靠性与功率分配效率。

English Abstract

Today, interests on hybrid ac/dc microgrids, which contain the advantages of both ac and dc microgrids, are growing rapidly. In the hybrid ac/dc microgrid, the parallel-operated ac/dc bidirectional interfacing converters (IFCs) are increasingly used for large capacity renewable energy sources or as the interlinking converters between the ac and dc subsystems. When unbalanced grid faults occur, the...
