Bifurcation Analysis of Active Electrical Distribution Networks Considering Load Tap Changers and Power Converter Capacity Limits

语言:

中文摘要

本文利用分岔理论分析了包含电力变换器和有载调压变压器(LTC)的有源配电网的参数稳定性和功率传输极限。文章推导了包含混合负载和电力变换器的典型配电网非线性模型,重点研究了以往常被忽略的变换器容量限制及变压器LTC对系统稳定性的影响。

English Abstract

The aim of this article is to analyze the parameter stability and power transfer limits of active distribution networks with power converters and load tap changers by using bifurcation theory.First, the nonlinear model of a representative distribution grid with mixed loads and power converters is derived. Frequently neglected effects of converter capacity limits and transformers with load tap chan...
