Multiagent Coupled Simulation of a Transportation System and Power Grid

Electric vehicles (EVs) are expected to play major roles in the pursuit of a low-carbon society; hence, using renewable energy to effectively charge EVs will be crucial. Interactions between road transport networks, in which gasoline-powered vehicles are used, and electric power systems maintained by controllable energy systems have not been considered. However, EVs, which are becoming increasingly popular, will spur such interactions. In this study, we propose a coupled simulation model that can represent the interactions between transport and electric power systems. Assuming high-output charging using fast chargers at charging stations for long-distance trips and low-output charging using a normal charger at home, we evaluate the time series change of load flow in urban power systems resulting from EV charging events.
