Analysis of Distribution Network Reliability Factors Based on AHP-Improved Entropy Weight Method and Gray Correlation Degree

In order to deal with the difficulties of similar weights of various reliability influencing factors in the distribution system and comprehensively assess the weight values of different influencing factors in the distribution network, a combination of the improved entropy weight algorithm and the Analytic Hierarchy Process (AHP) was incorporated into the grey correlation analysis algorithm. This integration allows for a holistic evaluation of subjective and objective perspectives on these factors, in order to improve the objectivity of its evaluation. Firstly, a hybrid approach integrating the Analytic Hierarchy Process (AHP) and the EntropyWeight Method was implemented to adjust multiple power supply reliability indicators. This modification aimed to establish comprehensive evaluation indicators for assessing power supply reliability. Secondly, use comprehensive evaluation indicators to conduct grey correlation analysis on the influencing factors of power supply reliability, calculate the final correlation degree of each influencing factor, and rank them. Finally, four power supply areas were validated, and the results showed that this method can effectively identify the factors that have a significant impact on power supply reliability. And it can provide the basis for the distribution network power supply reliability enhancement preferences, so that the distribution system to make timely targeted measures to greatly improve the efficiency of reliability enhancement.
