Abstract：The scientific and systematic evaluation of the development status of the new Electricity system is an important tool for promoting the energy revolution in the new era.Based on the panel data of 31 provincial administrative units from 2015 to 2022,focusing on the five requirements of"clean and low-carbon,secure and abundant,economic and efficient,coordinated supply and demand,flexible and intelligent",and the four main links of source,grid,load and storage,this paper adopts the entropy weighting method to calculate the comprehensive index of the development of the new electricity system,and evaluates the performance of regional differences,their sources and their distribution evolution by using the Dagum Gini coefficient and kernel clustering method.The results show that:during the study period,the development level of the new electricity system was steadily increasing in all regions.Realizing the requirements of"clean and low-carbon"and"coordinated supply and demand",as well as promoting the development of the source and the grid,are the main driving forces.The regional differences showed a widening trend,with interregional differences replacing intraregional differences as the main source of differences.Satisfying the requirements of flexibility and intelligence,and realizing the development of the load and the storage will be the key forces driving the development of new electricity systems and reducing regional disparities in the future.
