摘要
高比例新能源系统储能容量优化,对于提高新能源消纳能力,降低储能电站建设成本具有重要意义。研究了抽水蓄能、压缩空气、电化学储能等储能电站的容量效益、电量效益,提出了储能电站参与调峰的成本效益分析模型,进而提出了一种确定高比例新能源系统储能电站建设规模和型式的方法。以我国西北地区实际高比例新能源系统为研究对象,分析了储能的容量需求、各种储能的成本和效益,研究结果可为我国高比例新能源系统储能容量需求、储能规划和运行提供参考。
Optimizing the energy storage capacity of a high proportion of new energy system is of great significance for improving new energy consumption and reducing the construction cost of energy storage stations.The capacity and electricity benefit of energy storage stations are studied,such as pumped storage power station,compressed air,and electrochemical energy storage.A costbenefit analysis model for energy storage stations participating in peak regulation is proposed,and a new method of determining capacity and type of energy storage in a high proportion new energy system is proposed.Taking the actual high proportion of new energy system in northwest China as the research object,the energy storage capacity requirements,the costs and benefits of various energy storages are analyzed,and the research results can be used for China’s high proportion new energy systems to study energy storage capacity requirement,energy storage planning and operation.
