Due to the benefits to our environment and high economical efficiency, the local distribution network have been integrated with more and more renewable power resources, such as wind power. By using probabilistic load flow, this paper presents a new method to investigate distribution network's voltage security caused by wind power integrated. Giving wind speed randomness and other stochastic disturbances, such as varying loads, generation units, the probabilistic distributions of constraint violation of node voltages can be obtained. The presented method is tested on IEEE 34 node test feeder, and then analysis on different power connected points and load capacities with wind power integrated is made in this paper.
