Evaluation on key technologies for the construction of low-carbon index of electric power based on “double carbon”

Abstract

Abstract At a time when global climate change poses a major challenge to human survival and development, all countries believe that people must actively deal with green and low-carbon (LC) development. As one of the hot topics in recent years, the concepts of “carbon neutral” and “carbon peak” have a significant impact on the construction of New Energy (NE) systems. The construction of NE systems with NE as the main component is an important way to achieve the “double carbon” goal. Affected by the “double carbon” goal, the energy system has shifted to a low carbon and high intensity system, reducing the dependence on fossil fuel power generation, accelerating the use of clean energy, and promoting the supply system of low carbon and clean energy. In order to improve the LC construction of electric power, this article studied the key technologies of LC index construction of electric power under the background of “double carbon”. This article first introduced the LC construction of urban electric power, including the connotation of LC electric power, the current situation of NE development and the difficulties of LC construction of electric power in the context of “double carbon”. Then this article constructed a new type of LC Power System (PS) on the basis of double carbon, and introduced the framework of the system and the key technologies included in the system. Finally, this article verified the effectiveness of the new LC PS in LC construction through experiments, and put forward suggestions for the realization of LC power construction. The experiment showed that the new LC PS can greatly promote the construction of the LC index of power, and is conducive to the development of urban power. The proportion of urban non-fossil energy and the new installed capacity of non-fossil energy power generation have been significantly increased. Among the four cities studied in this article, the proportion of non-fossil energy in two cities has increased from less than 50 % to more than 50 %, which has greatly promoted the construction of LC index of electricity.
