Abstract
The introduction of shared autonomous electric vehicles (SAEVs), expected within the next decade, can transform the car into a service, accelerate electrification of the transport sector, and allow for large scale control of electric vehicle charging. In this work, we investigate the potential for this system to provide aggregated storage when combined with intermittent renewable energy sources. We develop a simulation methodology for the optimization of vehicle charging in the context of a virtual power plant or microgrid, with and without grid connection or distributed dispatchable generators. The model considers aggregate storage availability from vehicles based on transport patterns taking into account the necessary vehicle redistribution. We investigate the case of a grid-connected VPP with rooftop solar and the case of a isolated microgrid with solar, wind, and dispatchable generation. We conduct a comprehensive sensitivity analysis to study the effect of several parameters on the results for both cases.

We present a methodology for the optimization of shared autonomous electric vehicles (SAEVs) charging with distributed dispatchable generators (DG), renewable energy generators, grid electricity with variable pricing, vehicle-to-grid, and considering vehicles’ rebalancing requirements
The synergies between Shared Autonomous Electric Vehicles (SAEV) and renewable energy sources were studied in the context of a grid-connected Virtual Power Plant (VPP) and an isolated microgrid
Summary
New transport paradigms have been emerging in recent years thanks to the widespread use of connected devices. This is leading to a shift from car ownership to car sharing models of transportation. Users may sign up for both electricity and transport services from the same provider (the VPP/microgrid and SAEV operator), avoiding the costs of owning a private car. This scheme may lower the total costs of the system and may allow a larger penetration of renewable energy in the grid
