Exploiting the Hidden Capacity of MMC Through Accurate Quantification of Modulation Indices
Qianhao Sun, Jingwei Meng, Ruofan Li +5
The modular multilevel converter (MMC) has become increasingly important in voltage-source converter-based high-voltage direct current (VSC-HVDC) systems. Direct and indirect modul…
A Grid-Forming HVDC Series Tapping Converter Using Extended Techniques of Flex-LCC
Qianhao Sun, Ruofan Li, Jichen Wang +5
This paper discusses an extension technology for the previously proposed Flexible Line-Commutated Converter (Flex LCC) [1]. The proposed extension involves modifying the arm intern…
A Methodology for Power Dispatch Based on Traction Station Clusters in the Flexible Traction Power Supply System
Ruofan Li, Qianhao Sun, Qifang Chen +1
The flexible traction power supply system (FTPSS) eliminates the neutral zone but leads to increased complexity in power flow coordinated control and power mismatch. To address the…
Hierarchical Structure Design and Primary Energy Dispatching Strategy of Grid Energy Router
M. F. Chen, M. C. Xia, Q. F. Chen
As a core device of energy Internet, the energy router is deployed to manage energy flow between the renewable energy and electric grid. In this paper, a hierarchical structure of…
