With the expanding of the scale of wind farm, wind farm's impact on power grid becomes more serious, which would cause a lot of problems. This paper mainly focuses on the static stability for the power grid containing wind farms. The static stability margins at different wind farm outputs are obtained using continuous power flow method. Their probability distribution is also obtained with wind speed's Weibull distribution and the relation between wind speed and wind turbine output. Taking IEEE14 model with wind turbines connected as an example to analyze, the results have stated that wind farm output fluctuation has certain impact on the static stability of grid.
