Abstract: Building a zero-carbon power system based primarily on renewable energy is an important pathway for the transition to an all-electric society and the formation of a global clean and low-carbon energy system and also an important support for achieving the goal of“ carbon emission peak and carbon neutrality”. The white paper“ zero-carbon power systems based primarily on renewable energy” published by International Electrotechnical Commission is interpreted in this paper. Firstly, the background of the white paper is introduced and the key technologies and the challenges of the zero-carbon power system are discussed. Then, the standardization framework in the field of zero-carbon power systems is summarized. Finally, the direction of the new technology standards emerging in the zero-carbon power system is discussed. The construction of systematic international standards for zerocarbon power systems will provide important support for the safe operation of power systems.
