摘要: 综合考虑压缩空气储能系统经济性对于储能系统的设计和大规模应用具有重要意义。本文基于全寿命周期成本模型分析的方法,建立了不同类型的储气装置成本模型。通过计算储气装置的理论金属消耗量、储气装置的数量,同时在考虑制造难易程度的基础上来确定不同类型储气装置的最佳参数。通过对不同类型的储气装置进行全寿命周期成本分析和比较,可作为设计压缩空气储能系统及其经济性分析的参考。储气装置的全寿命周期成本(LCC)包括早期和后期成本。早期成本主要由原材料和设备成本构成,后期成本主要是运行维护成本。根据分析结果,储气管道的投资成本最低,且没有压力限制。地面储气装置的设备成本一般在2USD/kW·h左右。在确保安全的前提下,降低地面储气装置的LCC有利于压缩空气储能系统的推广实施和工程应用,大规模、有效地提高可再生能源的利用率,降低可再生能源的间歇性对电网运行的影响。

Abstract: The comprehensive consideration of compressed air energy storage economy is of great significance for the design and large-scale application of energy storage system. Based on life cycle cost analysis, a cost model of gas storage device is established. By calculating the theoretical metal consumption of the gas storage device and considering the difficulty of manufacturing and the number of gas storage devices, the best parameters of the gas storage device can be determined. Through the comprehensive analysis and comparison of the whole life cycle cost of different types of storage devices, it can be used as a reference for designing compressed air energy storage system and its economic analysis. The life cycle cost of gas storage devices includes early and late costs. The early cost is mainly composed of the cost of raw materials and equipment, and the later cost is mainly the cost of operation and maintenance. According to the analysis results, the investment cost of gas storage pipeline is the lowest and there is no pressure limit. The cost of equipment for surface gas storage is generally around 2USD/kW·h. Under the premise of ensuring safety, reducing the LCC of the ground gas storage device is beneficial to the promotion and application of the compressed air energy storage system. It can improve the utilization of renewable energy on a large scale and effectively, and reduce the influence of the intermittent energy on the operation of the power grid.

Key words: compressed air storage, gas storage device, economic analysis, life cycle cost
