The discussion on hot spot and frontier of energy research in smart cities

Abstract

Taking the journal documents published between 2008 and 2019 in the core collection of web of science as samples, using citespace software, a visual analysis of the research literature in the energy field in smart cities from the three dimensions of research evolution path, research hotspot, and research frontier. The results show that smart city energy research has gone through three stages: the initial exploration of theoretical concepts, the growth period of technology application, and the coordinated industrial development period. The research hotspots mainly focus on the demand research of energy construction in smart cities, the research of energy intelligent construction and the energy of smart cities Construct three aspects of related industry research; the frontiers of research mainly include energy internet, smart energy and big data.
