An Improved Cross Entropy Method for Energy Route Multi-Objective Optimization of Wireless Power Transfer Network
Authors: , ,
Abstract: Recent studies have shown that using relay resonators have the potential to extend the wireless power transmission distance and range. However, the relay resonators can only provide the relay power opportunities from source to relative long destination node without sacrificing too much efficiency, and the space utilization rate is low. To provide steady, high and real-time wireless power charging to any electrical device in a local area, in this paper, novel WPTN pattern called wireless power transfer network is proposed to this problem. In energy route design of WPTN, it is desired to achieve a maximum power transfer efficiency that provides higher output power for the load when maximizing the network reliability. This paper first introduces the basic idea of WPTN and network energy routes design. Then an improved Cross Entropy (CE) method using non-dominated sorting is proposed to solve the multi-objective energy routes problem in WPTN system. Finally, simulation results have demonstrated the effectiveness of the proposed method based on three case studies of 30-node WPTN system.
