Analysis and application of distribution uninterrupted work factors based on Interpretative Structural Model

Abstract

The uninterrupted operation of the distribution network is crucial for enhancing the security of power supply. However, factors such as environmental and line conditions may impede uninterrupted operation of overhead lines. Hence, this study conducts an analysis of factors that influence the uninterrupted operation of 10 kV overhead lines in distribution networks. To accomplish this, the Interpretative Structural Model (ISM) is employed to establish a hierarchical structure of the factors. Important factors are selected from this structure for the demand analysis of uninterrupted operation, and an optimization scheme for the design of overhead lines is proposed based on technical requirements for uninterrupted operation. Finally, the model is applied to optimize a real overhead line in a distribution network, thus validating the applicability of the proposed model.
