The 2022 2nd International Conference on Power System and Energy Internet (PoSEI2022) was held online on August 5-7 in Nanjing, China. PoSEI 2022 brought together innovative academics and industrial experts in the field of Power systems and Energy Internet in a common forum, promoting research and developmental activities in these fields.In the conference, we were greatly honored to have both Prof. Rongbang An from Jinan University, China and Prof. Hzalie Bin Mokhlis from University of Malaya, Malaysia to serve as our Conference General Chairmen. 90 individuals around the world took part in the conference. Divided into three parts, the conference agenda included keynote speeches, oral presentations and online Q&A discussion. Firstly, the keynote speakers were each allocated 30-45 minutes to address their speeches. Then in the next part, oral presentations, the excellent papers we had selected were presented by their authors one by one.Five distinguished professors were invited to hold keynote speeches during the conference. Among them, Prof. Min Wang from Hohai University, China performed a thought-provoking speech on the Correlation Analysis and Its Typical Application in Power System. The concept of correlation, classification, characteristics and its typical application in power system were studied in this research. Especially, some typical applications of correlation analysis in the field of power system research were discussed, including multiscale dynamic correlation analysis of Wind-PV power station output based on TDIC, research on microgrid two-way auction mechanism based on fixed effect Spatial Lagged Model, and risk assessment of distribution network equipment based on the Marcos method. Moreover, Prof. Hzalie Bin Mokhlis from University of Malaya, Malaysia made a report on: The Role of Nature Inspired Optimization in Power System Research. The presentation discussed the application of nature-inspired optimization techniques in recent power system research, covering the current challenges to power systems. And some examples of research work on the use of nature-inspired optimizations were also presented. Their insightful speeches had triggered heated discussion. And every participant praised this conference for disseminating useful and insightful knowledge.List of Committee member is available in this pdf.
