电氢耦合

3月27日，中国电力科学研究院有限公司技术战略研究中心室主任康建东在绿氢技术与氢电协同发展专题论坛上发表了《电氢耦合技术战略及发展趋势》的主题演讲。

针对风光富集地区大型新能源发电厂的弃风弃光问题，利用可逆固体氧化物燃料电池（reversible solid oxide fuel cell，RSOC）结合氢储能的双向转换特性消纳多余风光资源，提出一种双向可逆的集中式RSOC电氢耦合系统容量优化配置方法。首先构建集中式RSOC电氢耦合系统架构，建立发电系统、电氢转换系统等模型；其次考虑燃料电池特性建立RSOC性能衰减模型，考虑特高压通道可用传输能力不确定性生成典型场景；进而建立集中式RSOC双层容量规划模型，上层以运营期收益最大为目标优化RSOC、储氢库容量配置，下层以综合成本最低为目标优化各设备出力，联合粒子群算法与Cplex求解器进行求解。最后通过算例分析，验证RSOC的加入提高了系统经济性及环境效益，同时投资灵敏度分析表明电池单位容量成本是制约系统经济运行的重要因素。

针对新能源大规模接入给配电网安全运行带来的影响，开展了含混合储能的分布式电氢耦合系统与配电网间的多时间尺度交互策略研究。首先，提出分布式电氢耦合系统与配电网之间的平衡服务机制、需求响应机制等多元交互机制；其次，基于博弈理论，制定了电氢耦合系统与配电网之间的中长期与短期交互策略；最后，以某一典型区域的配电网与分布式电氢耦合系统为例进行仿真分析。算例结果表明：氢储能因其跨周期特性在中长期交互中具有优势；电化学储能响应迅速更适合短期交互；相较于单一形式储能系统，电氢混合储能系统能够有效降低峰谷差，提高系统收益，更契合现有配电网体系。 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 effe
