Impact of Wind Power Integration on Power System Out-of-step Oscillation
With the increasing scale of wind power integration, the impact on out-of-step oscillation cannot be underestimated. In this paper, for the research of the influence of wind power integration on power system out-of-step oscillation, first, using PSD-BPA software to establish wind-thermal-bundled equivalent single-machine infinite-bus system, innovative use the timeliness of the splitting device as a judgment of the degree of the system out-of-step. Now we can carry on simulation and analysis from 4 aspects as follows: the wind permeability, whether the wind farm is equipped with reactive power compensation or not , the type of wind turbines and different operation modes of wind turbines. Corresponding to the above four aspects, the results show that the larger scale of wind power integration, when the wind farm has reactive power compensation, with the constant speed wind cage type machine and in the constant voltage operation mode are conducive to curb power grid out-of-step oscillation, which also can improve the transient stability of the system.
