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 electro-hydrogen 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 cross-period characteristics. Electrochemical storage, distinguished by its rapid response, proves more suitable for short-term 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.
