Abstract

Vehicle-to-grid (V2G) technology offers a promising solution for grid stability with renewable energy growth. This study evaluates the 2030 potential and feasibility of V2G from battery electric vehicles (BEVs) across Chinese provinces, accounting for regional heterogeneity. Projections indicate that five provinces (e.g., Guangdong, Zhejiang) will each exceed 400 GW·h/day in theoretical storage capacity of BEV batteries. From the perspective of rational owners, the practically usable V2G storage potential reaches about 60% of that theoretical capacity. Participation willingness is primarily driven by local electricity price differences and BEV type, creating varied incentive requirements. Analysis shows this potential remains adequate for balancing grid fluctuations under high renewable penetration. Importantly, the relative distribution of provinces in terms of V2G feasibility is robust across scenarios. These findings are synthesized into a tiered pilot deployment strategy. This study integrates micro-level owner decisions with macro-scale regional analysis to guide China’s V2G pilot.
