Rethinking electrified transportation: The case for dynamic wireless charging
Dipanjan Ghose, Junjie Qin, S. Sivaranjani
Long-term infrastructure investment often requires choosing between an established technology and a capital-intensive alternative that gains value as demand matures. For electric v…
Braess' Paradoxes in Coupled Power and Transportation Systems
Minghao Mou, Junjie Qin
Transportation electrification introduces strong coupling between the power and transportation systems. In this paper, we generalize the classical notion of Braess' paradox to coup…
Traffic-Aware Microgrid Planning for Dynamic Wireless Electric Vehicle Charging Roadways
Dipanjan Ghose, Junjie Qin, S Sivaranjani
Dynamic wireless charging (DWC) is an emerging technology that has the potential to reduce charging downtime and on-board battery size, particularly in heavy-duty electric vehicles…
Competitive Equilibrium for Electricity Markets with Spatially Flexible Loads
Nan Gu, Junjie Qin
Electric vehicle charging and geo-distributed datacenters introduce spatially flexible loads (FLs) that couple power, transportation, and datacenter networks. These couplings creat…
Market-Driven Equilibria for Distributed Photovoltaic Panel Investment
Mehdi Davoudi, Junjie Qin, Xiaojun Lin
This study investigates long-term investment in distributed photovoltaic panels by individual investors. We consider a setting where investment decisions are driven by expected rev…
Extended Version: Non-Preemptive Scheduling of Flexible Loads in Smart Grids via Convex Optimization
Mehdi Davoudi, Mingyu Chen, Junjie Qin
This paper studies the scheduling of a large population of non-preemptive flexible electric loads, each of which has a flexible starting time but once started will follow a fixed l…
Global and Distributed Reproduction Numbers of a Multilayer SIR Model with an Infrastructure Network
José I. Caiza, Junjie Qin, Philip E. Paré
In this paper, we propose an SIR spread model in a population network coupled with an infrastructure network that has a pathogen spreading in it. We develop a threshold condition t…
