The invention relates to a method and device for determining weight factors of power distribution network operation state evaluation indexes. The method comprises the following steps of: obtaining m paired judgement matrixes corresponding to n evaluation indexes of a power distribution network operation state, wherein elements in the paired judgement matrixes express paired comparison results of the n evaluation indexes; calculating average values of elements at corresponding positions of the m paired judgement matrixes so as to obtain an averaging matrix; rejecting <delta>m paired judgement matrixes, dispersions of which do not satisfy a condition, in the m paired judgement matrixes according to the averaging matrix; respectively calculating maximum feature values of m-<delta>m paired judgement matrixes and feature vectors corresponding to the maximum feature vales; and determining weight factors of the n evaluation indexes according to the maximum feature values of the m-<delta>m paired judgement matrixes and the feature vectors corresponding to the maximum feature vales. According to the method and device, weight factors power distribution network operation state evaluation indexes can be correctly determined.
Description
technical field [0001] The present disclosure relates to the technical field of electric power engineering, and in particular to a method and device for determining a weight factor of a distribution network operation state evaluation index. Background technique [0002] At present, the research on the operation state of the power grid is mainly concentrated on the transmission network or the high-voltage distribution network. Most evaluation index systems are established for distribution network planning, and there is a lack of a complete evaluation index system for the distribution network operation state. A complete and realistic distribution network operation status evaluation index system can help operators to grasp the operation status of the distribution network in a timely manner, provide suggestions and references for the optimal operation of the distribution network, and contribute to the safety and quality of the distribution network. , Economic operation has a ver...
