In order to improve the accuracy of power supply reliability evaluation, this paper proposes a reliability evaluation method of distribution network based on consumers’ voltage quality sensitivity. Firstly, 6 indexes of power supply reliability are extracted and divided into general and other indexes to measure consumers-side experience and failure repair capability respectively. Secondly, according to the consumers’ voltage quality sensitivity, they are classified into sensitive consumers, general consumers and insensitive consumers. Based on the data of regional electricity consumers, consumers’ voltage sensitivity classification is obtained. After combining the voltage sensitivity classification of consumers with distribution network reliability index data, a reliability evaluation model of distribution network is established. Finally, an instance analysis shows that consumers’ sensitivity and the proportion of different consumers have significant influence on the evaluation results.
