| Summary: | Facing the current complex operation and management situation, power grid companies must improve the level of precision investment and improve the efficiency of project input and output. Based on the different goals of project investment, this paper uses comprehensive benefit evaluation methods to carry out micro-investment demand analysis from the project dimension, builds a quantitative evaluation index system for comprehensive benefits of power grid projects based on effectiveness contribution evaluation, and combines the analytic hierarchy process and entropy weight method to determine the index weights. Analyze the contribution degree of each project to the power grid after it is put into production through indicators, and realize the priority ranking of power grid investment projects according to the comprehensive benefit evaluation score of the project. The research results can provide reference and reference for improving the output efficiency of power grid investment projects.
