The conventional panoramic operation status evaluation of the power grid mainly uses the numerical values of power grid state variables to establish an evaluation matrix to obtain evaluation results,ignoring the influence of power grid data differences on the evaluation results,resulting in low reliability of the evaluation results.Therefore,a panoramic operation status evaluation method for power grids based on multi-layer models is proposed.First,clean the data,calculate the ordered interval,determine its consistency,reduce the influence of dissimilarity,construct an evaluation model,calculate the basic indicators separately and determine the weights,and obtain the results.The experiment shows that the reliability of the model is high(mean 0.92),which meets the needs of power grid operation and maintenance work.
