Optimization Design of Sectional Dynamic Power Supply Track Based on Improved CPSO Algorithm

As an important part of smart grid, EVs have many advantages in energy saving and low pollution and become a research hotspot. Based on the wireless power transfer technology, dynamic power supply technology develops rapidly and can effectively reduce the battery capacity of EVs. This paper the issue on the optimal design of sectional dynamic power supply track has been investigates the optimal design of sectional dynamic power supply track. For the optimal design of sectional tracks, a mathematical model of the minimal average annual comprehensive cost has been set up and a novel Cellular Particle Swarm Optimization (CPSO) based on PSO and CA are proposed to solve the nonlinear optimization problem. The results of numerical simulation show that it is more reliable to obtain the optimal design by CPSO rather than by PSO. Furthermore, the minimal average annual comprehensive cost is 60 thousand Yuan produced by CPSO less than that by PSO.
