Research on Vehicle to Grid Strategy of Multi-objective Optimization: A Case Study of Jiangsu Province

In pursuit of the 'carbon peaking and carbon neutrality' objectives and the imperatives of high-quality economic development, the energy system is undergoing a profound shift towards green and low-carbon solutions. Vehicle-network interaction offers the potential for adaptable synergy between energy supply and demand, aligning with the inherent requirements of new energy system development. This strategy aims to achieve efficient allocation of grid resources, provide cost-effective and convenient charging options for vehicle owners, and transform the relationship between electricity consumption and power supply from a traditional separation to a mutually beneficial symbiotic association. In this paper, we employ a multi-objective optimization model and non-cooperative tripartite game model, utilizing load data from Jiangsu Province, to evaluate pricing strategies that can foster a win-win scenario for grid operators and charging users in various conditions. Ultimately, it is found that vehicle-grid interaction not only plays a positive role in the energy transition of electric vehicles, but also expands the value space of electric vehicles, promotes a win-win situation for power grids, operators, and users, and promotes the interconnection of different subjects to realize integrated development.
