Research on the Regionalization Development of China’s Power Transmission Projects Considering Spatial Correlation

The construction of smart grid transmission projects and UHV projects plays an important role in promoting the formation of inter-provincial spatial connectivity and allocation and the optimal allocation of energy resources on a large scale in provinces and regions. Based on relevant data, this paper first sorts out the construction and development history of China's regional power grid and UHV transmission projects, and clarifies the connection of inter-provincial transmission projects and the characteristics of cross-provincial and cross-regional power transmission in recent years. Secondly, combined with the characteristics of the transmission and configuration of renewable energy power in transmission projects in China, the spatial connection weight matrix of power grid projects in different years is constructed, and the connectivity characteristics of transmission projects in the spatial dimension are compared and studied, and the development and change law of transmission power grid projects in China is analyzed, so as to provide reference for the construction of transmission projects.
