Network Reconstruction-considered Assessment of Distribution Network Node Vulnerability
Currently prevailing assessment methods for distribution network node vulnerability ignore the variation of dis-tribution network structure with the change of load state.To address this issue,this work carried out distribution network reconstruction by using the quantum particle swarm optimization algorithm with the objective of minimizing line loss.It then analyzed the extent of node vulnerability of the reconstructed network by integrating multiple vulnerability factors and assigned weights to various factors by using analytic hierarchy process,and finally,determined node's comprehensive vulnerability which integrated multiple factors.A simulative verification performed on the IEEE 33-node system indicated the reliability of the proposed method.
