摘要：

A large number of distributed generators accessing to distribution networks and the rapid popularization of electric vehicles have become the challenges for distribution networks. At the same time, the closed-loop design and open-loop operation of the distribution network generally lead to the serious unbalance of feeder power in the distribution network. In order to solve the problems above, this paper focuses on the research of the control technique of flexible multi-state switch for feeder interconnection in the distribution network. Based on the analysis on access modes and topology of the flexible multi-state switch, the principle of power exchange between the flexible multi-state switch and two feeder lines is analyzed. Then a new compound control strategy for the flexible multi-state switch is proposed. In this strategy, the DC bus voltage is controlled by all converters, which can simultaneously realize the functions of independent active power flow regulation and reactive power compensation. The simulation model and the prototype experiment platform are built, and the power flow control and the reactive power compensation function of two feeder lines are verified. The simulation and experimental results show that the proposed control strategy is effective and feasible. © 2018 Automation of Electric Power Systems Press.
