摘要：

Distributed Generation (DG), which is interlinked with distribution system, will inevitably have an impact to system. In the paper, a reliability evaluation method is proposed, which is based on the analysis to the structure and power flow of distribution system with distributed generation. First, a new concept, the smallest unit, is put forward for improving the fault traversal networks times. The authors use the Depth-First Search in data structure to divide distribution system into several the smallest units and propose the Islanding operation mode to increase the reliability of the system. Distribution system win be automatically turned into the Islanding operation mode once faults occur. To evaluate quantitatively the reliability of distribution system, Monte Carlo Simulation method is used by simulating the running status of distribution system. At last, the calculation results of actual case show that the proposed method is available to evaluate the reliability of distribution system with distributed generation.
