To address the growing and increasingly differentiated power supply reliability demands arising from the load diversification of new distribution systems,an optimal selection method for node reliability enhancement strategy combinations considering customized user demand is proposed in this paper.First,a risk tracing mechanism based on impact increments is developed to enable a rapid calculation of the contribution distribution of each component with respect to node indexes.Second,based on the reuse of impact values of the original system and the topological analysis,the reliability increment of various measures is efficiently evaluated.Third,the antagonistic coefficient is introduced to quantify the interaction effect between measures,and the influence of this effect on economic indexes is analyzed,enabling the optimal selection of schemes and practical guidance.Finally,a case study is used to validate the model’s effectiveness.Results demonstrate that the proposed method can trace the node reliability risk,significantly improve the calculation efficiency of node reliability increment while ensuring the accuracy,and reveal the influence of antagonistic effects between measures on reliability enhancement and economic performance,providing valuable guidance for the optimal selection of schemes and planning practice.
