摘要：
In order to realize the transmission of the active power flow between the series side and the system, the conventional distributed power flow controller needs to interchange the power through the third harmonic current. Since the special △/YN and YN/△ transformers are required at both ends of the branch where the series side is located, the installation location of the distributed power flow controller in the distribution network is limited. Thus, a novel distributed power flow controller (NDPFC) for distribution network is proposed in this paper. The operation principle of the NDPFC is analyzed, and its power flow regulation range and regulation characteristics are verified by the typical distribution network system. In addition, the mathematical model of electromagnetic transient in series side of novel topology is studied, and a control strategy for series side Ⅰ and series side Ⅱ based on the three-loop control is proposed to improve the robustness and control accuracy. Finally, simulations in different distribution network scenarios verify that the NDPFC can realize the power flow regulation for the distribution network, compensate for three-phase imbalance, promote renewable energy consumption, and improve the power quality. © 2021, Electrical Technology Press Co.
