Description:
With the access of distributed generations (DGs), the safe operation of distribution network has attracted much more attention. How to find out the weak nodes in distribution network is urgent to be solved. In this paper, based on complex network theory and risk theory, the improved node degree, node betweenness and node voltage over-limit risk index are proposed. Analytic hierarchy process (AHP) method isused togive index weights of node degree, node betweenness and node voltage over-limit risk. And the comprehensive index of the vulnerability of distribution network nodes is obtained by weighting. Finally, the feasibility of the index is verified on the IEEE33 nodes system. And accessing DGs to simulation, the influence of DGs on the vulnerability of distribution network is qualitatively analyzed.
