Digital project cloud model evaluation method and system

The invention relates to a digital project cloud model evaluation method and system, and the method comprises the following steps: carrying out the index screening of a pre-established comprehensive evaluation index system of a power grid digital project through a variable coefficient method, and carrying out the calculation based on a plurality of preset weighting methods, and obtaining a plurality of groups of weight combination data of a screened index; and based on the plurality of groups of obtained weight combination data, analyzing the sensitivity of the comprehensive evaluation index of the digital project by adopting a cloud model, and selecting the index weight with the best robustness to evaluate the digital project of the power grid to obtain a digital project evaluation result of the power grid. According to the invention, on the basis of the existing power grid digital project, index screening and weight value determination are carried out on a comprehensive evaluation index system; the comprehe
