Abstract

The electrification of transportation, driven by environmental concerns, has given rise to shared autonomous electric vehicles (SAEVs). Integrating SAEVs with Vehicle-to-Grid (V2G) technology, enhances grid stability and energy management. Unlike privately owned electric vehicles (EVs), SAEVs are managed by fleet operators who ensures that the vehicles are strategically positioned to meet immediate transport demands and longer-duration charging and V2G operations. This paper highlights key distinctions between EVs and SAEVs in V2G systems and offers a detailed analysis of SAEVs' unique features that enhance their role in V2G integration. Their coordinated fleet dispatch minimizes idle time, maximizes V2G participation, and ensures optimal energy distribution more effectively than conventional EVs. However, SAEVs pose greater operational challenges due to connectivity, reliance on public charging hubs, and the need to balance transport services with grid participation, while EV participation in V2G is highly dependent on user willingness. This study reviews control strategies and optimization frameworks for managing EV and SAEV charging and discharging, addressing key objectives, constraints, and uncertainties while highlighting their differing requirements and interdependencies. It further examines the benefits, challenges, and mitigation strategies for V2G integration, providing key recommendations for future research and development in this sector.

期刊介绍： eTransportation is a scholarly journal that aims to advance knowledge in the field of electric transportation. It focuses on all modes of transportation that utilize electricity as their primary source of energy, including electric vehicles, trains, ships, and aircraft. The journal covers all stages of research, development, and testing of new technologies, systems, and devices related to electrical transportation. The journal welcomes the use of simulation and analysis tools at the system, transport, or device level. Its primary emphasis is on the study of the electrical and electronic aspects of transportation systems. However, it also considers research on mechanical parts or subsystems of vehicles if there is a clear interaction with electrical or electronic equipment. Please note that this journal excludes other aspects such as sociological, political, regulatory, or environmental factors from its scope.
