中文摘要

本文提出了一种基于柔性交流端口固态变压器(FACP-SST)的增强型软常开点(e-SNOP),旨在解决现有全功率变换方案成本高、体积大的问题。该方案具备灵活的功率流控制、无功补偿及直流源荷接入能力,有效提升了配电网的灵活性与集成能力。

English Abstract

The enhanced soft normally-open point (e-SNOP) can integrate large-scale dc sources and loads into the ac grid, featuring flexible power flow control, reactive power compensation, and accommodation of new dc sources and loads. A novel e-SNOP based on the flexible-ac-port solid-state transformer (FACP-SST) is proposed in this article to alleviate the high cost and large volume of existing full-powe...
