Abstract: The energy storage selection and cost analysis is the basis of its allocation in wind farm,which is of great significance to enhance wind farm operation and reduce total investment.However,the quantized conclusion is rarely given.In the aspect of economic analysis,there are few literatures to analyze the key factors that affect the energy storage cost.In this paper,the performance and application status of energy storage technology are summarized.The ES-Select software and the application in energy storage selection analysis is also described.The cost model is established from two aspects of cost structure and cost indicators,and the influence of efficiency,replacement period and charging cost on ES cost are analyzed.The results show PUMP and CAES has more advantages in the application of wind farm.In addition,the effective way to reduce cost for PUMP and CAES is decreasing electricity cost and improving the efficiency,while for lead acid and NaS battery is to prolonging the cycle life and improving the efficiency.

Key words: wind power, energy storage, model, economic

摘要: 风电场中储能技术的选型和成本分析是储能配置的依据之一,对提升风电场运行特性和降低总投资具有重要意义,但目前针对储能在风电场集成应用中的选型很少给出量化的结论。在经济性分析方面,也少有文献分析影响储能成本的关键因素。本文介绍了储能技术在风电场的作用和应用现状,简述了ES-Select软件及其在风电场应用中的储能选型分析方法,阐述了储能的成本构成和成本指标,分析了循环效率、更换周期和充电成本对各类储能技术成本的影响。ES-Select的选型定量分析,指出抽水蓄能和压缩空气储能在风电场集成应用中更具优势;提出有效降低抽水蓄能和压缩空气储能成本的方法是降低用电成本和提高效率;有效降低铅酸电池和钠硫电池储能成本的方法应重点延长更换周期,其次需要提高效率。
