Study on Carbon Emission Evaluation of Power Grid Construction Projects Under Dual Carbon Targets

Abstract

Under the dual-carbon target, as the intermediate hub connecting power production and consumption, the low-carbon development of power grid is of great significance to the development of power industry and even the whole society. Comprehensive evaluation of carbon emissions from power grid construction projects is an important part of realizing low-carbon power grid. Based on the existing research results, this paper studies the index system and evaluation method of low-carbon power grid construction projects. According to the analysis of carbon emission sources of power grid construction projects, the comprehensive evaluation and core evaluation index system of low-carbon power grid are designed, and the low-carbon comprehensive quantitative evaluation method is constructed to form a comprehensive evaluation model of low-carbon power grid. In the construction of the index system, through the horizontal comparison and vertical comparison of power grid construction projects, the analytic hierarchy process is selected to calculate the index weight. Finally, through the comparison of the advantages and disadvantages of the construction project options, a comprehensive analysis of the evaluation criteria of low-carbon power grid construction is made, and a comprehensive evaluation system suitable for evaluating the carbon emissions of power grid construction projects is obtained.
