Coupled Infrastructure Simulation of Electric Grid and Transportation Networks

This paper presents a framework for coupled infrastructure studies between the electric power transmission system and transportation networks. The proposed methodology evaluates the impact of electric vehicle (EV) charging demand on grid. operation and power generation, Key modeling and coupling considerations are presented for each network, Case studies for various EV charging schemes are presented on networks situated in Travis County, TX for illustration. System loading and generation dispatch provide examples of two of the many analyses enabled by this coupled infrastructure simulation framework.
