Low-carbon Evaluation Index System and Method for the Whole Life Cycle of the New Power System

Abstract

Purposes The construction of new low-carbon power grids for the whole society has an important role in promoting the development of low-carbon economy, and the establishment of a new power system whole life cycle low-carbon evaluation index system is of great significance to the development of low-carbon power grid. Methods On the basis of the analysis of the whole life cycle of the new power system low carbon grid, three primary indicators of economy, reliability, and low carbon were constructed at first, and then nine secondary indicators were screened on the basis of the primary indicators to evaluate the low carbon grid. A comprehensive evaluation index system with a core evaluation index system of the new power system low carbon grid for the whole life cycle was established, and a detailed explanation of the significance of each indicator in the system was provided. Results By using a large amount of statistical data from the power grid, typical scenarios with different new energy ratios were established and simulated. The obtained evaluation results of low carbon indicators for different scenarios prove the feasibility of the low carbon grid evaluation index system established in this paper.
