Abstract：

In response to the impact of the widespread integration of new energy sources on the secure operation of distribution networks, a study is undertaken to explore a multi-time scale interactive strategy for distributed electrohydrogen coupled systems, incorporating hybrid energy storage and distribution networks. Firstly, interactive mechanisms including the balancing service mechanism and demand response mechanism between distributed electro-hydrogen coupled systems and distribution networks are proposed. Secondly, based on game theory, medium-to-long-term and short-term interactive strategies are formulated for electro-hydrogen coupled systems and distribution networks. Finally, a simulation analysis is executed utilizing the distribution networks and distributed electro-hydrogen coupled system in a representative region as an illustrative example. The outcomes of the case study underscore that hydrogen storage exhibits an advantage in medium-to-long-term interactions due to its crossperiod characteristics. Electrochemical storage, distinguished by its rapid response, proves more suitable for shortterm interactions. In comparison to singular energy storage systems, a hybrid electro-hydrogen storage system can effectively mitigate difference between peak and valley loads, enhancing system benefits, and seamlessly aligning with the existing distribution network system.
