Electric vehicles have become more popular due to a swift global transition to low-carbon and renewable energy sources in recent years. Technological advancements have led to the emergence of a new generation of vehicle-to-grid electric vehicles. These vehicles can simultaneously play the triple role of load, resource, and energy storage. Though the battery capacity of an electric vehicle is minuscule compared to the power system, considering the connection of many electric vehicles to the grid and their controllability, grid operation could be improved. Traditional thermal power plants could be used to support electric vehicles, but it is worth noting that this would be economically and environmentally expensive. Using renewable energy sources can reduce environmental pollutants, preserve natural resources, and expand the use of renewable energy sources. The optimum scheduling of electric vehicles as loads or sources has significant potential for evolving a sustainable integrated electricity and transportation infrastructure. In this paper, a model for optimum utilization of vehicle-to-grid electric vehicles is proposed and developed, while both traditional power plants and renewable energy sources are supplying the required power to the network. Optimum utilization of gridable vehicles and renewable energy sources improves grid operation and increases spinning reserve capacity during peak times.
