This paper presents a method for penetration capacity calculation of wind farm based on probabilistic constraint. According to the stochastic programming theory, under a confidence interval, a mathematical model that considers the randomness of wind speed is established based on the static safety and power quality constrains. The solving method is proposed according to particle swarm op­timization algorithm and stochastic simulation technique too. According to a real power system in Yunnan, the penetration capacity of wind power is calculated under different confidence interval, and the feasibility and effectiveness of this method are verified too. The related factors of affecting the penetration capacity of wind power are analysed, which provide the reference for the planning and design of wind farm.
