A Dynamic Power Transfer Route Construction and Optimization Method Considering Random Node Distribution for Wireless Power Transfer Network

Wireless power transfer network (WPTN) is composed of nodes and power transfer routes, which can supply power for group devices. In the WPTN, it is difficult to build a definite power transfer route under the random node distribution condition. In this article, a dynamical construction and optimization strategy of power transfer route is proposed to adapt to random node distribution. In order to establish a definite route among grouping nodes, each node is designed to switch its role flexibly through a topology switching method. Furthermore, in the switching process of power transfer route, the switching method of node role shows that the transition is smooth. Then, an actual WPTN with five randomly distributed nodes verifies the effectiveness of the proposed method.
