用户侧分布式电化学储能的经济性分析
|
摘要
随着电池技术的不断发展,分布式电化学储能在电力系统中的应用日益广泛,但目前受成本和使用寿命的限制,缺乏商业模式的支撑,其经济性仍然存在问题。分析了分布式储能所产生的相关潜在经济效益,给出了一种判断分布式电化学储能应用于削峰填谷的经济性判断方法,并着重对铅碳电池和磷酸铁锂电池在削峰填谷应用场景下的经济性进行对比分析,并提出了相关的补偿建议。
With the development of battery technology, the application of distributed electrochemical energy storage in power systems has become more widespread. However, current electrochemical energy storage is limited by cost and service life and lacks of support from commercial models, the economy of electrochemical energy storage remains a concern. This paper first analyzes the potential economic benefits generated by distributed energy storage, and gives a method for judging the economy of distributed electrochemical energy storage for peak shaving and valley filling, and focuses on the comparative analysis of the economy of leadcarbon batteries and lithium iron phosphate batteries in peak shaving and valley filling, and proposes relevant compensation suggestions.
