Optimal Self-Scheduling for Fast EV Charging Station on Highway: A Tunnel Case Study

Highways are one of the main locations where installing an Electric Vehicle Charging Station (EVCS) is crucial. This paper introduces a novel concept to overcome the main challenge in this regard, which is the lack of enough electrical transmission systems close to the roads. The main idea is to leverage surplus power generated from nearby tunnels that have exclusive power supply. By capitalizing on excess power from the tunnel infrastructure, this study explores the feasibility of ultra-fast EVCSs facilities. The research investigates contingent upon the available power supply, with dual objectives: foremost, to optimize the accommodation capacity for EVs at the charging station, and secondly, to minimize the wait times for charging sessions. Employing advanced scheduling algorithms and mathematical optimization techniques, the study delineates optimal self-scheduling strategies for managing the charging infrastructure efficiently. This research contributes insights into the potential synergies of transportation infrastructure for the development of robust and efficient EVCSs along highways.
