摘要
建立稳定、高效、智能化的可再生能源系统是能源转型的重要路径。本文基于可再生能源系统专利梳理技术框架,运用社会网络分析揭示国内外技术关联现状与动态特征。可再生能源发电、储能、多能互补与智慧电网专利申请数近年上升,相关技术可分为能源获取与运用、能源转化和能源系统3类,对应13个技术领域;中国技术网络密度持续上升,技术关联以“能源获取与运用-能源转化”与“能源转化-能源系统”为主;日本技术网络密度较低,技术关联以“能源转化-能源系统”为主;美国技术网络密度近年维持较高水平,技术关联由“能源获取与运用-能源转化”转向“能源转化-能源系统”。研究成果能够为能源产业技术创新与融合、产业间协作提供实证参考。
Establishing a stable,efficient,and intelligent renewable energy system is important for promoting energy transition.Based on the patents of renewable energy systems,this study sorts out the technology framework systematically and uses social network analysis to reveal the current status and dynamic characteristics of technology associations in China and abroad.The results show an increasing trend has occurred recently in the number of patents related to renewable energy generation,energy storage,multi-energy complementation,and smart grids.Technologies for renewable energy systems can be divided into three categories-energy acquisition and application,energy conversion,and energy system construction-covering 13 technology fields.Compared with other countries,the technology network density in China continues to rise;most of its technology associations are in two modes-“energy acquisition and utilization-energy conversion”and“energy conversion-energy systems construction”.The technology network density in Japan is relatively low,and the latter mode dominates its technology associations.The United States has a high level of technology network density in recent years,and most of its technology association modes are shifting from the former to the latter.These findings not only serve as empirical references for technology innovation and integration in renewable energy development,but also provide practical implications for collaboration between energy industries.
