System Modeling and Simulation of Dynamic Wireless Power Transfer Roadways

Abstract

Electrified roadways employing dynamic wireless power transfer (DWPT) technology require the installation of a power distribution system feeding a large number of highly variable power electronic loads. The design of such systems may benefit from detailed system simulations, which can be computationally expensive and challenging to set up. This paper develops a systematic time-domain modeling approach for DWPT roadways using the generalized state-space averaging method, enabling system-level analysis at time scales of interest to the power system analyst. A case study is used to demonstrate the utility of these models in investigating the impacts of design choices, traffic conditions, and electrical transients.
