【 摘 要 】

The reliability of active distribution system is important for power system operation and users convenient. In order to evaluate the reliability of distribution system quickly and effectively, this paper established the output model of photovoltaic generation system and wind turbine generators considering more random factors. Then considering that the calculating complexity bring by above model and Monte Carlo method, this paper provided network simplification method based on feeder partition. Then this paper designed parallel calculation project for reliability evaluation to improve calculating efficiency. At last, simulation example verified the effectiveness of active distribution system reliability evaluation.
