An Automatic Identification Method for Coherent Generator Groups Based on Analytic Hierarchy Process Model
摘要
Abstract
In view of the existing subjective and one-sidedness problems in the process of coherence identification for dynamic equivalence,the influences of various factors on the coherence of generators are taken into account.By drawing on the experience of analytic hierarchy process(AHP)for reference,a practical AHP model is developed.Key factors,such as swing curves,electrical distances and generator parameters,are combined to change the process of coherence identification from single dicision-making to multi-attribute decision-making.Through the comparison between the coherence matrixes of the standard systems with known coherence and the similarity matrixes of various factors, the AHP judgment matrix is determined,while the weight of each factor is determined objectively.The distributed clustering method is used to obtain the final similarity matrix,then the coherent generator clustering is completed.Simulation results of the IEEE 1 18-bus 54-unit system and Western Inner Mongolia power grid show that the method proposed is effective and practical.关键词
