Scheduling optimization analysis of electric vehicle and building roof photovoltaic system based on V2G technology

As electric vehicles become increasingly widespread, their influence on the power grid is expanding as well. In V2G (Vehicle-to-Grid) mode, the integration of large-scale electric vehicles into the grid presents numerous challenges, primarily related to the fact that existing photovoltaic system scheduling strategies do not account for the charging and discharging requirements of these large-scale electric vehicles. To address this issue, this paper introduces a V2G management and control system for electric vehicles. This system is developed by considering V2G technology, time-of-use (TOU) pricing, the load of the building’s regional power grid, and the current status of connected electric vehicles. Through simulation, the proposed systematic charging and discharging scheduling strategy for building rooftop PV and electric vehicles is demonstrated to be correct and effective. It enhances the economic benefits of the building area and reduces operational costs.
