配电网与分布式电氢耦合系统的交互策略研究OACSTPCD

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 ef-fectively mitigate difference between peak and valley loads,enhancing system benefits,and seamlessly aligning with the existing distribution network system.
