多能互补系统国际发展态势分析

International Development Trend Analysis of Multi-energy Complementary System

多能互补系统通过多种能源之间的相互补充和梯级利用以提升能源系统的综合利用效率,具有缓解能源供需矛盾,实现新型低碳、高效能源系统构建,多能协同利用等优点,世界主要国家均给予高度关注,纷纷制定多能互补能源发展战略,并开展了相关技术研发和试点项目。本文从国际相关的多能互补系统战略布局、项目部署、关键前沿技术进展等几个方面对多能互补能源系统国际发展态势进行分析,并从专利计量的角度深入分析国内外分布式能源技术专利申请趋势、地区分布、研究热点、主要专利权人等信息,进而提出中国多能互补能源系统未来发展对策建议。

Multi-energy Complementary System(MECS)can make full use of multiple energy resources and improve the comprehensive energy efficiency by complementary and gradient utilization of energy.It is of great significance to construct a low-carbon,safe,efficient energy system and ease the contradiction between energy supply and demand.Given the above benefits of MECS,strategic plans,research and demonstration work of MECS are being developed in major countries and regions of the world.At present,many achievements in various fields have been made,such as renewable energy grid connection,smart grid,smart community,demand-side management and so on.This article mainly analyzes the international development trend of MECS from aspects of international relevant strategic planning,research projects deployment,research progress and key frontier technologies.Meanwhile,the trend,regional distribution,research hotspot and main patentee of distributed energy technology at home and abroad are analyzed through patent bibliometric.Based on the above analysis,several suggestions for MECS development in our country are put forward.
