Abstract：In order to improve the accuracy of wind farm equivalent models under wind speed unequal distribution, a multi-machine representation method is proposed for the wind farm dynamic equivalence with fixed-speed wind turbines. Using the wind turbine similar operating point as the grouping rule of wind turbines, the proposed method defines the new cluster classification index. Then the wind turbines are dynamically grouped by clustering algorithm, and the parameters calculating methods and simulation modeling process of equivalent model are provided. Thus a wind farm model represented by multi equivalent wind turbines is obtained. Compared with the traditional equivalent methods, the simulation results show that the proposed cluster classification index is effective, and the proposed multi-machine equivalent model can more accurately describe the dynamic characteristics of the wind farm at the grid integration point.
