摘要
第三次工业革命为能源互联网的发展提供了契机和客观条件。储能技术是能源互联网建设的关键技术之一,但是现有文献对储能作用的关注往往集中在削峰填谷、平抑功率波动及提高可再生能源发电的接入比例上,对能源互联网背景下储能的功能和作用方式还缺乏比较系统全面的阐述。本文对储能在能源互联网中所扮演的角色提出了一种新的且较为全面的认识,首先分析了能源互联网中的储能需求,包括能源互联网中需要储能参与实现的目标及其对储能系统的基本要求;然后系统地总结了储能技术在能源互联网中的多种功能,除了文献中广泛关注的削峰填谷、平抑功率波动等,还包括多能源系统之间的耦合与解耦、可再生能源的充分利用、新的能源管理与交易模式,等等;接着阐述了储能在能源互联网中的基本作用方式;最后说明了储能在能源互联网中的作用方式、功能与需求之间的对应关系。
The third industrial revolution provides the opportunity and possibility for the development of Energy Internet. Energy storage technology is one of the key technologies of Energy Internet. The existing literatures on the function of energy storage mainly focus on peak shaving and valley filling,suppressing the power fluctuations,and increasing the rate of renewable energy generation connected to the grid,but lack of systematic and comprehensive analysis of the function and action manner of energy storage at the background of Energy Internet. In this paper,a new and comprehensive understanding of the role of energy storage in Energy Internet is proposed. The paper firstly analyzes the demands of energy storage in Energy Internet,including some development goals of Energy Internet,which can be achieved with energy storage,and basic requirements of energy storage in Energy Internet. Then several functions of energy storage in Energy Internet are summarized. Besides peak shaving and valley filling,and suppressing the power fluctuations,which are mainly focused in existing literatures,there are several functions of energy storage,including coupling and decoupling among multi-energy systems,full utilization of renewable energy,new energy management and transaction model,etc. After that,the basic action manners of energy storage in Energy Internet are expounded. Finally,the correlation between action manners,functions and demands of energy storage in Energy Internet are analyzed.
