Reliability assessment of distribution network considering differentiated end-users demand for reliability

Abstract

Abstract In view of the importance of the distribution network in the power system and the current problem of the fragmentation of the reliability assessment of distribution network considering differentiated end-users demand for reliability index of the distribution network, this paper proposes a comprehensive assessment method for the reliability of the distribution network. Based on the distribution network data obtained from the perception layer of the Internet of Things, the main assessment indices for the reliability of the distribution network based on the power supply capacity and the number of users, and the reference assessment indices for the reliability of the distribution network based on the reliability price are calculated respectively. Then according to the index scoring standards, the reliability assessment result of the distribution network is obtained. A case study is used in this paper to verify the effectiveness of the proposed comprehensive assessment method.
