With the establishment and acceleration of power grid new infrastructure construction, the power grid is becoming increasingly complicated. It is very important to correctly understand the development state of the power grid. Therefore, an improved dynamic fuzzy evaluation model is proposed for power grid development diagnosis, and corresponding rating assessment on power grid development is carried out. Firstly, a dynamic evaluation index system is established based on an analysis of the important indexes in all aspects of power grid development. Then, the trend characteristics of each state are analyzed by the methods of membership function and cluster analysis. Finally, the hidden Markov model is used for the comprehensive rating of power grid development. A case study is carried out with actual data of a provincial power grid, which shows that the rating results conform with the actual status, and are helpful to understand the dynamic features of power grid development.

Based on the actual national conditions of China’s economic and social, energy and power development, this paper analyzes China’s carbon neutralization mechanism framework and puts forward the mitigation solutions for carbon emissions with China energy interconnection. With the target of optimal cost for achieving carbon neutrality for the whole society, the MESSAGE integrated assessment model (IAM) is used to study the overall pathways for China’s whole society carbon neutralization and the transition pathways for energy and power system based on the China energy interconnection. The results show that the carbon neutrality pathways before 2060 for China can be advanced in view of three stages of early peaking, rapid mitigation and overall neutrality. The carbon emissions will reach their peak around 2028; 90% of the energy demand will be met by clean energy in 2060, and electricity will account for two-thirds of the whole society end-use energy consumption, achieving the total transition of the energy use system. Besides, some key issues for achieving carbon neutralization are analyzed, including emission reduction speed and pace, power system balance and adjustment, and transition cost and allocation.
