Abstract: Driven by the goal of carbon neutrality, the safe, efficient, and low-carbon transition of the power energy system with digital and intelligent technology innovation has become important development strategies in China. Firstly, this paper discusses the connotation and requirements of the energy revolution for the construction of a new power system from the perspective of the national macro strategies. After that, the reform process of the new power system is introduced and the key elements of the fossil energy-dominated power system, the double-high power system, and the new power system are analyzed. On this basis, the basic characteristics of the new power system are introduced, and the six key elements of the new power system are presented, namely "generation", "grid", "demand", "storage", "decarbonization", and "digitization". The relationships between the six elements are analyzed. Finally, starting from the core motivation driving the development of the new power system and the methodologies to build the new power system, the key technologies of the new power system from the "carbon perspective" and the key technologies in the process of the power system digital transformation are explored and prospected.
