The 2022 International Conference on Power Engineering and Electrical Technology (ICPEET 2022) was successfully held in Nanjing, China from July 22nd to 24th, 2022 in the form of online conference. The conference aimed to provide a platform for experts and scholars in the fields of power engineering and electrical technology to share research achievements and cutting-edge technologies, understand academic development trends, broaden research ideas, strengthen discussion, and promote industrial cooperation of academic achievements.We had the honor of having invited Prof. Hongwei Li from Southwest Petroleum University, China to serve as our Conference General Chair. About 160 individuals and enterprises all over the world attended the conference. Divided into three parts, the conference agenda covered keynote speeches, oral presentations, and online Q&A discussion. Firstly, keynote speakers were each allocated 30-45 minutes to hold their speeches. Then in the oral presentations, the excellent papers we had selected were presented by their authors one by one.During the conference, we were delighted and honored to invite three sophisticated keynote speakers to address their speeches. Among them, Assoc. Prof. Kwan Yiew Lau from Universiti Teknologi Malaysia delivered a speech on the topic: Tailoring Dielectric Properties of Polymer Nanocomposites. To address the problems hindering the use of nanocomposites as practical high voltage insulation materials, he proposed nanofiller/polymer interface modification techniques to tailor the dielectric properties of nanocomposites. The importance of the local material structure in determining the dielectric properties of nanocomposites was also discussed. Additionally, Professor Yiming Zhang from Fuzhou University gave a report on Foreign Object Detection Technology in Electric Vehicle Wireless Charing System. In the report, different foreign object detection techniques were reviewed and a new metal object detection system with novel coil layouts and topologies was proposed. The wonderful and dramatic speeches of each keynote speaker had triggered heated discussion. Moreover, every participant praised this conference for disseminating useful and insightful knowledge.The proceedings of ICPEET 2022 is a compilation of the accepted papers and represent an interesting outcome of the conference. These papers feature but are not limited to the following topics: Electric Power Allocation, Smart Grid and Technologies, Power System, Electric Vehicle Technology, Electromagnetic Compatibility, etc. All the papers have been checked through rigorous review and processes to meet the requirements of publication.On behalf of the conference organizing committee, we would like to express our heartfelt appreciation to all the keynote speakers, peer reviewers, and all the participants. In particular, we would like to acknowledge the Journal of Physics: Conference Series, for the endeavor of all the colleagues in publishing this paper volume. We firmly believe that all the attendees have had fruitful discussions and gained valuable knowledge, and will enjoy the opportunity for future collaborations.List of Committee member is available in this pdf.
