Research on the Structural Optimization of the Clean Energy Industry in the Context of Dual Carbon Strategy-A Case Study of Sichuan Province, China

As a major province for hydroelectric power in China, Sichuan Province has witnessed a great amount of seasonal characteristics in its hydroelectric power, endowing the clean energy industry in Sichuan with the characteristics of unstable supply in different seasons, strong power transmission capacity, and low production capacity of other non-fossil energy sources (except hydroelectric power). In this study, the mathematical model method was used to construct a structural optimization model of the clean energy industry in Sichuan Province, and to enable a quantitative analysis of the rationalization of the clean energy industrial structure in Sichuan Province. The results are proved from the cost-effectiveness of low carbon emission that hydroelectric power > wind power > photovoltaic power > natural gas > coal > oil. This study shall find the theoretical structure of the clean energy industry in Sichuan Province in 2030 with a prediction of Sichuan Province's total future energy output and a constraint of its industrial structure model of clean energy. This paper suggests that Sichuan Province should give priority to the development of non-fossil energy sources, increase the development and utilization of power transmission channels in wet seasons, and develop clean energy and high energy consumption industries and the construction of pumped storage power stations, so as to reduce and avoid the waste of energy resources. It is also suggested that Sichuan Province should focus on developing clean energy with the capability of peak shaving, such as hydrogen energy and natural gas, while developing smart grid and long-distance transmission technology to strengthen energy conservation and emissions-reduced power generation. On this basis, Sichuan will focus on the development and utilization of natural gas as an alternative to high-carbon energy, with a view to optimizing its industrial structure of clean energy and helping China achieve the dual-carbon goals.

Automated summary

As a major province for hydroelectric power, Sichuan Province in China has a seasonal characteristic in its clean energy industry, which includes unstable supply, strong power transmission capacity, and low production capacity of non-fossil energy sources. A mathematical model was used to analyze and optimize the industrial structure of clean energy in Sichuan Province. The study found that hydroelectric power, wind power, and photovoltaic power have better cost-effectiveness in terms of low carbon emissions compared to natural gas, coal, and oil. The recommendations include developing non-fossil energy sources, improving power transmission channels in wet seasons, and focusing on clean energy with peak shaving capabilities, such as hydrogen energy and natural gas.
