Abstract: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.
