能源互联网背景下的电力储能技术展望

基于能源互联网的特征,给出了广义电力储能的定义,提出了储能在能源互联网中的2种应用模式。对电化学储能、电动汽车、储热、储氢等将在能源互联网中发挥重要作用的储能技术现状进行了分析,并对储能在能源互联网中的关键应用技术进行了探讨。指出了新能源发电和储能的协调规划和调度技术、基于储能的能源路径和能源分配策略、储能与能量转换装置的集成设计和协调配置、考虑储能的能源交易机制是储能在能源互联网应用中的几项关键技术。

Outlook of Electrical Energy Storage Technologies Under Energy Internet Background

Based on the characteristics of the Energy Internet, the definition of electrical energy storage is put forward. Two application modes of energy storage in the Energy Internet are proposed. The current status of electro-chemical energy storage, electric vehicles, heat storage and hydrogen storage which will play important roles in the Energy Internet is analyzed. The key technologies of energy storage implementation in the Energy Internet are discussed. Finally, some key technologies of energy storage implementation in the Energy Internet are pointed out: the coordinated planning and scheduling of energy storage and renewable energy generation; the optimal energy path dispatch and energy management based on energy storage; the integrated design and configuration of energy storage and energy conversion; and the market mechanism for energy trading considering energy storage.
