[0001] This invention relates to the field of power grid investment decision-making technology, and in particular to a method and system for calculating and allocating power grid investment scale based on data analysis. Background Technology

[0002] With the rapid development and increasing complexity of power grid-related businesses, the investment scale and number of projects in the entire power system continue to expand. To improve the accuracy of power grid investment decisions, it is necessary to scientifically calculate and allocate the scale of power grid investment. However, existing calculation and allocation methods have some problems, mainly including: 1. The scale calculation mainly relies on manual experience and simple adjustments to historical base figures, lacking objective data support and quantitative analysis models, resulting in highly subjective scale calculation results and affecting accuracy; 2. The allocation process often adopts an average allocation method, without fully considering the differences in indicators or characteristics of different special fields (such as differences in the urgency of actual needs, benefit potential, and strategic importance), resulting in resource misallocation; 3. When the overall control scale changes or the initial allocation results need to be adjusted, the adjustment process is cumbersome and time-consuming, and the basis for adjustment is unclear, making it difficult to quickly respond to business changes and optimize the overall resource allocation efficiency.
