基于专利信息的微电网技术全球发展与竞争动态分析

意在探究微电网技术目前的全球发展与竞争动态,通过利用Innography专利分析平台对全球微电网技术的专利申请、专利布局、技术来源、研发机构竞争动态、技术主题分布等状况进行分析。并结合社会网络分析,探讨不同专利强度类型的技术主题和技术来源国家的分布状况。研究发现,能源存储、配电技术、电源是微电网相关技术重点研究的领域,中国的微电网专利总数领先于世界其他各国,但大多数为一般专利;而美国掌握着绝大多数微电网的重要和核心专利;研究结果表明,中国在微电网高价值技术专利上的研发还未达到世界领先水平。

Analysis of Global Development and Competition of Microgrid Technology based on Patent Information

Microgrid represents the future trend of energy development and has become the primary objective of energy equipment construction in China. Through Innography, a patent analysis platform, this paper analyzes the global development of Microgrid technology from patent applications,patents layout,technology source, organization competition perspectives. Combining with the social network analysis(SNS), 2-mode network of countries and technical topics has been constructed to further explore the distribution of technologies and sources of countries based on the different patent strength types(general, important, core). It found that the total number of Microgrid patents in China is ahead of other countries ,but most of them are the general patents. The United States holds the vast majority of important and core patents and technologies of Microgrid. The key research areas of Microgrid are Energy Storage, Distribution Power, Power Source. This research reveals the global development and competitive situation of Microgrid technology, and provides important reference for China"s technological development and industrial policy formulation in this field.
