Research on microgrid control technology based on patent analysis

Search on patent applications for microgrid control technology was conducted on a global scale, analyzing the development lifecycle, main applicants, technology development direction, important patents, and overseas patent layout of microgrid control technology. From the results, it can be seen that microgrid control technology has gone through two stages, namely the technology start-up period and technology development period. Patent technologies are mainly concentrated in categories such as H02J3, G02J13, and G06Q50. Overall, the research focus of microgrid control technology is to improve the stability, reliability, coordination, and economy of control systems. Research on improving power quality and operation flexibility can be further studied. Based on the analysis of the main applicants’ patent technology, important patents, and overseas patent layout, it is recommended that relevant Chinese enterprises increase their research on smart control technology and pay attention to the layout of patents.
