摘要: 单一类型的储能设备难以兼顾多种类型储能设备的优势,而混合储能系统能够综合不同类型储能介质的技术与经济优点。针对在并网模式下蓄电池和氢储能的混合储能的优化配置问题,以经济性和环保性为目标函数,选择各分布式电源的数量为设计变量,采用层次分析法解决多目标权重问题,采用粒子群算法求解微电网容量优化配置,通过经济性和评价指标分析对比不同储能配置方案。结果表明,混合储能的成本比单一的蓄电池和氢储能分别降低了2.46%、10.02%,自平衡率比单一蓄电池和氢储能分别提高了7.65%、23.89%,冗余度比单一蓄电池和氢储能分别降低了19.00%、38.16%。

Abstract: A single type of energy storage device is difficult to take into account the advantages of multiple types of energy storage devices, while the hybrid energy storage system can integrate the technical and economic advantages of different types of energy storage. Aiming at the optimal configuration of hybrid energy storage based on battery and hydrogen energy storage in grid-connected mode, economic and environmental protection are taken as the objective function, the analytic hierarchy process is used to solve the multi-objective weight problem, and the particle swarm optimization algorithm is used to solve the optimal configuration of microgrid capacity. Different energy storage configuration schemes are analyzed and compared by economy and evaluation index. The results show that the cost of hybrid energy storage is 2.46% and 10.02% lower than that of single battery and hydrogen energy storage. The self-balancing rate is 7.65% and 23.89% higher than that of single battery and hydrogen energy storage, and the redundancy is 19% and 38.16% lower than that of single battery and hydrogen energy storage.

Key words: hybrid energy storage, capacity optimization configuration, new energy power generation, multi-objective optimization
