摘　　要：从技术、经济层面对储能电源参与电网调频的选型进行研究。总结提炼不同形式储能电源的技术经济指标,技术上采用层次分析法(analytic hierarchy process,AHP)进行排序选型,得到技术排序结果;经济性上利用年均值法进行排序选型,得到经济排序结果;对技术/经济选型排序结果赋权计算,得到技术经济综合最优的选型结果,并对各成本因素进行灵敏度分析,总结得到影响各类型储能经济性的敏感因素。最后针对典型二次调频场景,利用该文方法进行选型,知Li-ion、PHS、CASE是技术占优的储能方案,CASE、飞轮储能(FW)、LAB经济占优,而CASE、Li-ion、PHS是技术经济综合最优方案,由灵敏度分析知进一步降低Li-ion的功率成本,将使其成为技术经济两者同时最优的储能电源。The technical and economic selection method of energy storage power supply for grid frequency regulation is studied.First,the technical and economic indicators of different forms of energy storage power supply are summarized, the analytic hierarchy process (AHP)is technically used for rank and selection,and technical rank results are obtained ; in economic aspects,the annual average cost of energy storage power supply is used to get the rank and selection.The weighted calculation of technical/economic selection and rank results is carried out to get the comprehensive optimal technical/economic selection results,and analyze the sensitivity of each cost factor,and summarize the sensitive factors affecting the economy of all types of.energy storage.Finally,aiming at the typical secondary frequency regulation scene, this method is used for selection,the results show that Li-ion,PHS,CASE are technology-preferred energy storage solution,CASE,Flywheel (FW),LAB are economically dominant,CASE,Li-ion and PHS are the technical and economic comprehensive optimal plan.It is known from the sensitivity analysis that reducing further the power cost of Li-ion,which will make it become the optimal energy storage power supply for both technology and economy.
