摘要
大规模新能源发电和众多分布式可再生能源接入电网给电力系统运行与规划带来了新的问题和挑战。储能是电力系统实现高比例新能源发电消纳不可或缺的资源。首先简要分析主要储能类型的转换原理、技术优缺点、适用范围,重点探讨了热能储能以及电制氢气、电制天然气等储能技术。在此基础上,对能源互联网背景下储能系统在发电、输电、配用电以及多能源系统互联中的研究现状进行了梳理和分析。
The integration of more and more large-scale renewable energy generation and distributed renewable energy generation brings new problems and challenges for the power system operation and planning. Energy storage is the indispensable resource to achieve the absorption of renewable energy generation with the high ratio integration. This paper firstly introduces main types of electric storage systems from the perspectives of energy conversion principles,technical advantages and disadvantages and applicable ranges,and mainly discusses thermal storage as well as power-to-gas and power-to-hydrogen storage. On this basis,this paper combs and analyzes the research status of energy storage in different sectors of power systems,i. e.,power generation,transmission,distribution and demand sides,and multiple energy system interconnections under the background of energy internet. Lastly,this paper gives an outlook of the challenges and the corresponding research directions on the application of energy storage in the future.
