Low-Voltage Management for Distribution Network Based on Parallel Flexible DC System: The Fujian Experience

This paper takes the distribution network in Fujian province in china as an example, and summarize the reasons for low-voltage problem in distribution network firstly. Then compare the traditional technical measures for low-voltage management in Fujian distribution network. Furthermore, a parallel voltage regulating scheme based on flexible DC technology is proposed to address the issue of low-voltage at the end of distribution network, which is caused by long power transmission line and seasonal overload. Finally, a practical engineering application case and economic analysis are presented.
