综合能源系统关键技术综述与展望

Review and prospect of core technologies of integrated energy system

文章将综合能源系统关键技术归纳为多能协同规划设计、优化运行技术、智能化技术、能源转换技术、储能技术、能源梯级利用技术、电能替代技术和需求响应技术。首先,介绍了国内外IES的发展现状;然后,全面分析总结了综合能源系统关键技术的核心问题,涵盖了基础理论、关键材料、核心元器件和设备装置等;最后,结合各技术的典型应用场景对其发展趋势进行了展望。

Integrated energy system(IES)is an intelligent,low-carbon and efficient new generation energy system,featuring energy-centered,renewable energy priority and multi-energy collaborative optimization.At present,most of the existing reviews of IES focus on a specific technology,and there is still lack of a systematic review of IES core technologies.This paper divides the core technologies of IES into seven categories:multi-energy collaborative planning,design and optimizing operation technology,intelligent technology,energy conversion technology,energy storage technology,energy cascade utilization technology,energy substitution technology and demand response technology.Firstly,the status of IES at home and abroad is introduced.Then,the key points of the above seven core technologies of IES are analyzed and summarized,including basic theory,key materials,core components and equipment.Finally,the future research directions of each technology are forecasted according to the typical application scenarios.
