Abstract:
In the process of establishing electric power market, higher quality and reliability of electric power system are becoming more and more important for customers. To meet these requirements, it is important to have some calculations to maintain power supply reliability for customers, starting from the electric power system design and planning process. In this paper, the graph analysis method is introduced to calculate electric power distribution system reliability (radial power distribution system with backup power sources). Based on splitting load by regions, establishing matrix structure, relations between regions, and relations between sources and regions, the method identifies reliability indexes. The method considers the influence of the operation time of the disconnector and the priority of power supply from the reserves that have limited capacity.
