The advent of the fourth information revolution has made the digital economy a major driver of energy transition and low-carbon development. The overall architecture of smart energy is based on intelligence as the core, and based on infrastructure platforms such as intelligent cloud and IoT, as well as AI middle platform, Data middle office ether, etc. And with the help of cloud computing, artificial intelligence, big data, blockchain, digital twins and other technologies, smart energy can promote the intelligent transformation of energy enterprises ultimately.Against such background, the 2023 2nd International Conference on Smart Energy and Electrical Engineering (SEEE 2023) was held via hybrid form during December 22nd to 24th, 2023 in Malaysia. It was attended by about 50 researchers, scientists, engineers, and students working in the fields of smart energy and electrical engineering.The aims of SEEE 2023 are:To create an academic forum for sharing, communication and research at the international level, so that participants can be informed of the latest research directions, contents and results of smart energy and electrical engineering.To provide approaches to the main problems facing smart energy and electrical engineering, creating spaces that encourage discussion and joint development of research, technology development, and innovation.The excellent papers selected form the submissions were approved for presentation at the Conference and publication in this Conference Proceedings. Among the submissions are some submitted from abroad, but are unfortunately not accepted after rigorous review processes.There was an enabling environment for discussion and exchange of ideas, during which topics such as Core Technology of Intelligent Energy Equipment, Smart Transmission and Distribution, Power Grid Dispatching and Automatic Control, Power Systems and Energy, Electrical Theory and New Technology, etc. were presented. Some of the important issues were the sharing and discussion of Wireless Power Transfer and its Application on Electric Vehicle Wireless Charging by Prof. Yiming Zhang (Fuzhou University, China), Corona Loss Characteristics of EHV/UHV AC Transmission Lines by A. Prof. Shilong Huang (North China Electric Power University, China), Integrated Renewable Energy System based on Hydrogen by Prof. Mohan Lal Kolhe (University of Agder, Norway), etc.As in the last meeting, SEEE 2023 was again a space for the integration of undisputed knowledge and sharing of peer experiences within the specific areas of smart energy and electrical engineering. Both conference and presentation sessions were attended by many conference attendees, allowing closer relationships, both academic, as well as scientific and personal. The cordiality and good treatment of the attendees promoted a climate of friendship, which we could enjoy during all the development of the conference agenda.We would like to extend an enthusiastic round of thanks to all our conference authors and speakers for their excellent contributions. We are indebted to the Technical Program Committee for their efforts in making and pushing the conference program. Thanks also to the members of Journal of Physics: Conference Series for making the publication of SEEE 2023’s Proceedings possible.List of Committee Member is available in this pdf.
