Full-voltage-class target grid optimization evaluation method

The invention belongs to the field of electric power, and particularly relates to a full-voltage-class target grid optimization evaluation method, which comprises the steps of calculating evaluation index values of target grids with different voltage classes; performing normalization processing on the evaluation index value by using an index scoring function to obtain an index score; calculating the weight of each evaluation index; establishing an evaluation index model; and calculating by using the index score and each evaluation index weight through an evaluation index model to obtain an index comprehensive score. The technical scheme adopted by the invention has the following beneficial effects that the full-voltage grade is covered by a plurality of voltage grades, so that the evaluation of the full-voltage-grade target grid is realized. Secondly, evaluation indexes are constructed from multiple dimensions of power grid load capacity matching, grid transfer capacity flexibility, grid structure standard no
