Study of index system of economic operation of grid based on gray correlation degree
摘要
Abstract
One method for establishing the index system of economic operation of grid is proposed based on gray correlation degree. It achieves the combination of the objective theory and expertise. First, the status of grid operation is analyzed in depth,and based on which the subjective hierarchical evaluation index is established. And then the gray relation theory is used to filter the strong correlation index in each secondary index category, which can eliminate redundancy. At the same time, the absolute correlation matrix of the primary index is calculated by defining the center indexes. It can verify the rationality of subjective indicators classification, and amend the unreasonable one by gray relation clustering. Meanwhile, the index system also can be adjusted depending on the experts' needs. The eventual indicator system of power grids that can meet both the objective and subjective requirement is set up. Thus, the conclusive result of simulation example demonstrates the effectiveness of the indicator system and algorithm.关键词
