Present Situation and Prospect of Optimal Configuration of Switching Devices in Distribution Network

Optimal configuration of switch devices in distribution network is nonlinear combinatorial optimization problem that concerns with many factors such as investment of switch devices, operation and maintenance cost and outage cost. In this paper, the present research situation of optimal configuration of switch device home and abroad in recent years is summarized, the research achievements in objective function selection, modeling, solution algorithm and application as well as existing problems are expounded; the further research direction of optimal configuration of switch devices, including the improvement in accuracy of algorithm and calculation speed, the consideration of reliability and parameter uncertainty, the expansion of static modeling and so on, are looked ahead.
