An Improved (F&V) Based Passive Islanding Detection Strategy With Reliability Evaluation

Abstract

The quantitative reliability analysis plays a significant role in assessing the performance of the distribution system operation strategy. This analysis is greatly influenced by customer interruption. In this paper, the islanding issue is considered as a customer interruption. The islanding is detected by simultaneous measurement of F&V (Frequency and Voltage) variation using passive islanding detection method. The detected islanding is prevented by installing diesel generator or battery depending on the power balance in the detected islanded buses. In this study, the proposed methods of islanding detection and prevention is tested on IEEE- 135 radial bus distribution system in the presence of various Distribution Generation (DG) units.
