Abstract: China will achieve the goal of peak carbon dioxide emissions in 2030 and carbon neutrality in 2060,which will have a profound impact on China′s energy and economic system. Firstly, the purpose and meaning of carbon neutrality, and the policies and measures at home and abroad for carbon neutrality are analyzed. Secondly, the path design of carbon emission reduction of Sichuan power system for carbon neutrality is proposed. Finally, the suggestions for integration of large-scale renewable energy, flexible resource allocation, stability of large system with low inertia, high elasticity of power grid are proposed. According to the preliminary estimation, carbon emission reduction in Sichuan will occupy about 3% of the goal of national carbon neutrality.
