摘要:The current evaluation index of the distribution network is large, the index system is complex, the randomness is strong, and the information redundancy problem between indicators is highlighted. A method for constructing the evaluation index system based on hierarchical dynamic grey relational analysis is proposed. Firstly, find the initial index that affects the operating state of the distribution network. Then, through the proposed hierarchical dynamic gray correlation analysis method, the comprehensive correlation degree between the initial indicators is obtained, and the elements in the comprehensive correlation degree vector are dynamically filtered to select a more accurate evaluation. Indicators; then verify the validity and rationality of the post-screening evaluation indicators with the information contribution rate of the indicators, and establish a final evaluation index system. Finally, through the example analysis, the evaluation results obtained by the evaluation index system constructed in this paper are consistent with the actual operation of the distribution network, which proves the reliability and rationality of the constructed indicator system, which can provide effective guidance for the optimal operation of the distribution network.
