Research on the Technical Standard System for Power Carbon Emission Reduction

A scientific and rational technical standard system for power carbon emission reduction (TSS-for-PCER) is a critical element in both of advancing the construction of a new electricity system (NES) and achieving carbon peaking and carbon neutrality goals. With the gradual construction of NES, it is clearly that the TSS-for-PCER shall cover the entire power industry chain. In this paper, based on the Hall three-dimensional structure, using the method of combining “top-down” and “bottom-up”, firstly, the development status of technical standards for power carbon emission reduction was reviewed. Then, the standard requirements of various stakeholders in the industry were summarized. the standard requirements in the carbon reduction field from various stakeholders in the power industry is studied. Finally. a multi-level TSS-for-PCER architecture of “3+6+N+N” has been proposed. The TSS-for-PCER is characterized by 3 levels of basic support, core implementation, and management evaluation, 6 dimensions of basic universality, carbon emission accounting and verification, carbon emission monitoring, carbon reduction technology and equipment, carbon emission assessment and evaluation, and carbon emission management, 20 technical fields, and 33 categories. To maintain the advancement of the TSS-for-PCER, it is necessary to conduct regular evaluations of it and adjust the technical fields and corresponding subjects. Therefore, the number of both technical fields and categories are represented by N+N. Finally, specific implementation suggestions were provided from four aspects: implementation direction, path, guarantee, and development. The standard system has not only successfully filled the standard gap in the field of domestic power carbon emission reduction technology, but also achieved the coverage of the whole process of power carbon emission, which is systematic, progressive and scalable, providing a comprehensive and suitable standard guidance for the future development of the power industry carbon emission reduction.
