Accuracy Enhancement of Weak Node Identification in Complex Distribution Networks Using BCWSM-AHP Model
To improve the identification accuracy of weak nodes in complex distribution networks affected by looped structures and distributed generation, this study pioneers the integration of the binomial coefficient weighting set method (BCWSM) and analytic hierarchy process (AHP), proposing a BCWSM-AHP model for enhanced weak node detection. Based on complex network theory, the model establishes an evaluation system comprising five novel indices of improved node degree,enhanced node PageRank,refined node electrical betweenness,power flow incremental impact,node voltage stability.This system enables the comprehensive assessment of weak nodes in complex distribution networks. By optimizing criterion-layer weight allocation via the binomial coefficient weighting method, the subjective consistency index of expert judgments is reduced from 0.047 to 0.015, significantly mitigating subjectivity inherent in traditional AHP. Case studies demonstrate that the BCWSM-AHP model achieves the more precise localization of critical weak nodes in active distribution networks.
