中文摘要

本文提出了一种基于分裂直流母线电容拓扑的四线制模块化多电平变换器(MMC),作为异步微电网(ASMG)功率调节系统(PCS)的解决方案。该方案旨在解决无变压器结构下微电网并网的复杂设计与控制挑战,特别是在处理不平衡负载支撑方面的应用。

English Abstract

A four-wire modular multilevel converter (MMC) with the split dc-link capacitor topology is a promising solution for a power conditioning system (PCS) of an asynchronous microgrid (ASMG). In an ASMG, the PCS is applied to connect two distribution-level systems with a transformerless structure, which has numerous challenges in the design and control of the MMC. However, in the existing literature, ...
