Abstract
The current situation of the energy crisis requires various industries around the world to seek technological upgrades to achieve energy conservation. The renovation of power grid lines, transformers, and substations significantly affects the comprehensive benefits of power transmission/distribution systems, and the optimization of specific parameters of these elements plays a critical role in their operational performance. In order to determine the effects of these parameters and realize their accurate optimization, herein, we establish a method combining an analytic hierarchy process and an entropy weight method to calculate the weightings of the indexes, and then evaluate the comprehensive benefits through a cloud model. Based on the evaluation system above, a case study was utilized to analyze the power transmission/distribution system of a designated area in Wuhan City, and the results showed that the comprehensive benefits increased by around 5.4% compared to 2022, and could be upgraded to level IV in the cloud model with the technical transformation. This exhibits the effectiveness and the application feasibility of this evaluation system.
