Abstract:

The electrification of the transportation system is one of the key components toward a sustainable society. The technology for Electrical Vehicles (EVs) has sufficiently advanced that an accelerated adoption of EVs is increasingly likely. Crucial to the transition toward an EV based transportation is a Large Scale Charging (LSC) infrastructure. By LSC we mean charging systems at public parking facilities, work places, and apartment complexes where a large number of EVs are charged simultaneously.

In this talk, we consider the design of an energy management system for the large scale charging of electric vehicles based on the concept of network switched charging where charging ports are activated based on the available renewable sources, real-time price of electricity, and the level of local storage. At the heart of the energy management system is a deadline scheduling algorithm that exploits the available charging capacity and customer's flexible schedule.
