![]() Consequently, SG has become a recent developmental trend for the world power grid, which can improve the efficiency and reliability of the power grid, reduce peak demand ( El-Hawary, 2017), realize automatic control, and self-repair ( Gungor et al., 2011). Smart grid (SG) with the ability of rapid response and self-repair has become an important solution to the above problems, as SG can promote the use of clean energy, improve the efficiency of power generation and energy utilization, improve the transmission efficiency of power grids, and improve the energy efficiency of terminals ( Yuan and Hu, 2011). The integration of large-scale renewable energy in power systems is inevitable, but large-scale renewable energy is intermittent and variable, which has a great impact on the power grid. The findings of this paper provide some enlightenment on China's SG research, which can present scholars with an overview of the macro perspective, help them understand the latest development of the SG field in China and offer useful guidance for future research in this subject as well. The research themes during 2010–2018 have deepened with most studies focusing on the traditional power system. Furthermore, China's SG research shows a trend from a single theme to diversified development. Taking into consideration the impact of SG on traditional power systems, the main hotspots cover demand response, micro-grid, distributed generation, and electric vehicle (EV). Taking into consideration the impact of the information and communication field on SG, the major current research hotspots include wireless sensor network (WSN), internet of things (IoT), smart meter, big data, and security. Besides, the research hotspots have obvious interdisciplinary characteristics. Firstly, the volume of publications in China's SG is on the rise, and the cooperation between countries and institutions is getting closer. The results consequently demonstrate some valuable insights. Hence the purpose of this study is to get access to the research status, development, and trends of SG in China based on the 3,558 published papers obtained from the WOS core library and application of the bibliometric method and visualization analysis software VOSviewer and alluvial diagrams. Smart grid (SG) offers great advantages in renewable energy integration and has become a popular trend of modern power development recently meanwhile China is the second most prolific country using SG. 2School of Foreign Languages, Huaiyin Normal University, Huai'an, China.1School of Management, China University of Mining and Technology, Xuzhou, China.
