Abstract: In order to overcome the information barrier of power-transportation system and improve the low utilization rate of renewable power generations, a distributed planning model of renewable vehicle energy supply system considering seasonal hydrogen storage is proposed in this paper. Firstly, an energy supply architecture including winter-summer cross-seasonal hydrogen storage is proposed, and the operation behaviors of distribution network, combined energy supply station, and transportation network are modeled. Secondly, an electric-transportation joint planning model is established with the goal of economy. Then, a tailored alternating direction multiplier methool（ADMM） is proposed to realize the distributed solution of energy supply system and transportation system. Finally, the validity and advancement of seasonal hydrogen storage model and distributed algorithm are verified based on IEEE 33-node power distribution network and 12-node typical transportation network, and the synergies among various storages are discussed.
