The Energy Internet represents a transformative paradigm integrating advanced power systems, distributed renewable energy, and digital technologies to achieve efficient, resilient, and sustainable energy management. Energy Internet,sponsored by Chinese Society for Electrical Engineering (CSEE), and published by China Electric Power Research Institute (CEPRI) in cooperation with the Institution of Engineering and Technology (IET), is a multidisciplinary gold open access journal covering power and energy, power. Advancing the Energy Internet: Innovations and Solutions for a Sustainable., Internet of Things in Energy, connects energy sources and consumers (or prosumers, more generally) of various energy types (power, gas, heat, cooling, etc. ) through. This paper discusses the current problems in various technical areas and possible future research directions by locating the key technologies in the blockchain of electricity trading in the energy Internet, so as to provide reference for further research and implementation of the energy blockchain.
