Reliability evaluation of distribution system based on hybrid method and network simplification

This paper presents a new method for distribution evaluation based on Monte Carlo simulation and minimal path. Firstly, a simplification model is constructed according to switches using for disconnecting the failure component. Then the failure element and failure duration time is simulated with Monte Carlo Method. Using section topology matrix finds which fault type each section belongs to. Thus, the fault type of every load point is obtained. Finally, failure occurrence times and failure duration time of each load points are counted. Thereby, the basic reliability indices of the distribution system could be calculated.
