Abstract
In view of the advance of dynamic wireless power transfer (DWPT) for electric vehicles (EVs) charging, integrated DWPT systems are conceivable to emerge. However, quasi-continuous and time-varying DWPT charging loads bring large challenges to the power flow analysis of integrated DWPT systems. In this paper, a sequential load model is proposed to describe the temporal dependency of DWPT charging demands. Furthermore, on the basis of back/forward sweep method, a new power flow analysis method is addressed to deal with quasi-continuous and time-varying DWPT charging loads. Then a daylong sequential power flow simulation is conducted on a test system. Simulation results show that the fluctuation of branch flows varies significantly. Adequate power and energy managements are necessary to integrated DWPT systems.
