Abstract


With the rapid development of wind power, wind power grid-tied become the bottleneck of wind power development. In this paper, from two aspects, qualitative and quantitative analysis of the influencing factors of wind power acceptable capacity, the specific quantitative method is given to select access location and determine the maximum power injection of wind farms. Assessing the influence of voltage level and network loss when the wind farm is connected to the power grid, which are prioritized and then determine the reasonable grid connection point. By adopting the combination of static and dynamic analysis method to determine the maximum power injection. First, determine the maximum power injection of wind farms by the static constraint conditions, and then, get the wind power which can keep the grid transient stability by considering the influence of wind speed change and power grid fault mode in the transient analysis, which is the acceptable maximum wind power of that grid connection point. Finally, measures to raise the capacity of wind power acceptance are given on the basis of research above.
