Electric energy state evaluation index selection method

The invention belongs to an index selection determination method, and particularly relates to an electric energy state evaluation index selection method. The method comprises the following steps: 1, sampling; carrying out basic parameter sampling; 2, normalizing the data; performing data normalization on the sampling parameters; 3, calculating a compensation value; calculating three compensation values; 4, calculating a weight; calculating weights of different parameters; 5, revising the weight; revising the weight; 6, selecting parameters; and performing parameter selection according to the corrected weight Wj. The method has the remarkable effects that (1) a plurality of specific indexes which greatly influence the operation of the power grid are selected as evaluation basic indexes; (2) the basic weight of each index is calculated through the mutual relation of the parameters; and (3) by correcting the basic weight, the index can reflect the operation state of the existing power grid to the greatest extent
