Research On Domestic And International Energy Internet Based On Bibliometrics

With the development of the times and social progress,the demand of users changes.The traditional energy system is difficult to meet the ever-changing energy demand.Energy Internet came into being.The energy Internet has multiple attributes such as openness,interconnection,equivalence and sharing,which is one of the reform directions to solve the future energy crisis,so it has attracted the attention of scholars all over the world.However,as a new research field,the theory of energy Internet is not mature and its development path is unpredictable.In addition,different countries' basic national conditions,different backgrounds of various researchers,and domestic and international cultural differences will make the research of energy Internet show different characteristics.It is not known whether international experience and peer standards can be directly used for reference in the study.Therefore,it is very important to further grasp the evolution of energy Internet by means of literature measurement and knowledge map.In this paper,information visualization tools are used to visualize domestic and international energy Internet research,more intuitively show the research framework,research hotspot and frontier evolution of energy Internet in 2008-2018,analyze and discuss the differences between domestic and international research in the future and the future development trend of energy Internet.Based on the theory of visual knowledge map and reading a large number of relevant literature,this paper uses CNKI and web of science core databases to collect domestic and international relevant literature,and combines the preliminary search content and Cite Space to screen high-frequency words and keywords for continuous feedback search.Using Excel and Cite Space to sort out the domestic and international retrieval literature,including the author's analysis and comparison,keyword clustering analysis and emergent word analysis and comparison,to show the research hotspot and frontier of domestic and international energy Internet.Through the identification of domestic and international key authors through the frequency of literature,and through the analysis of the contents of their works,the important research ideas of domestic and international core authors are analyzed;through the screening of high-frequency keywords,the clustering situation of high-frequency keywords is displayed,the relationship between each keyword and the main keywords in the clustering is minedto highlight the research theme,and the comparison of countries is made from the aspects of energy Internet mode,technology,users and applications Based on the time zone map of co-occurrence of emergent words and the intensity of emergent words,combined with the starting and ending time of emergent words and the trend change,this paper shows the evolution mode of research frontier,and makes comparative analysis and prediction of domestic and international research trends.Finally,through the comparison of domestic and international research literature,this paper analyzes the differences between domestic and international research,and puts forward suggestions for the research of energy Internet in China based on the actual application of energy Internet in China.
