摘要
介绍了超导储能系统和电化学储能成本的技术经济分析模型,研究了混合储能系统在电网中的应用方法。针对福建某风电场应用环境,引进10MJ/37MW高温超导磁储能系统和20MWh/5MW磷酸铁锂电池储能系统,分析弃风与风电收入。通过计算风电弃风损失、新建输电线路投资和混合储能系统的投资成本,比较新输电线路与混合储能系统的收益。评估结果将为混合储能系统在可再生能源电网应用的经济性分析提供重要参考。
This paper presents the technology economic analysis model of a superconducting magnetic energy storage system（SMES）and a battery energy storage system（BESS）,and the application method of hybrid energy storage system in power grid.In view of the application environment of a wind farm in Fujian,a 10 MJ/37 MW high temperature SMES system and a 20 MWh/5 MW ferrolithium phosphate BESS system were introduced to analyze the wind abandon and wind power revenue.By calculating wind abandon loss of wind power,investment of new transmission lines and investment cost of hybrid energy storage system,it compares the benefit of new transmission lines and hybrid energy storage system.The evaluation results will provide an important reference for the economic analysis of the application of hybrid energy storage system in renewable energy power grid.
