摘要:

多元储能技术作为优化能源结构、促进新能源开发和保护生态环境的重要手段是构建新型电力系统的关键环节。本工作根据储能规模化发展需求,聚焦规模化多元电化学储能的度电成本与经济性。文章从多元电化学储能技术的应用现状出发,考虑到电化学储能的成本构成和特性,建立了多元储能优化全寿命周期LCOE模型,对电化学储能技术的经济性进行了测算。分析表明,提高电化学储能经济性的关键在于降低储能的初始投资成本或单位容量成本。最后,结合我国国情对规模化电化学储能的经济发展进行了总结与展望。

关键词: 多元电化学储能, 应用现状, 优化全寿命LCOE模型, 经济性

Abstract:

Multiple energy storage technology that optimizes the energy structure, promotes new energy development, and protects the ecological environment is the key to realizing new power systems utilizing new energy sources. This paper investigates the cost and economics of large-scale multiple electrochemical energy storage that meets the requirements of energy storage scale development. We first introduce the current application situation of domestic multi-electrochemical energy storage technology. To this end, we establish and measure the levelized cost of energy model for optimizing multi-electrochemical energy storage. We found that the power cost of electrochemical energy storage gradually decreases with increasing scale of the energy storage. In a comparison study, we then reveal that to improve the economics of electrochemical energy storage, we must reduce either the initial investment cost or the unit capacity cost of energy storage. Finally, we propose the economic development of future large-scale energy storage under China's national conditions.

Key words: multiple electrochemical energy storage, application status, optimized full-life LCOE model, economics
