Applications of an Improved Equivalent Wind Method for the Aggregation of DFIG Wind Turbines

摘要：

Recently wind energy has developed at a fast pace,and it is necessary to develop equivalent models to represent dynamic behaviors of wind farms on power system.The equivalent wind method has been investigated for the aggregation of DFIG wind turbines.The detailed procedure for the calculation of equivalent wind has been analyzed.The necessity of classifying incoming winds has been shown.In order to improve the performance of the equivalent wind method,this paper proposes to classify incoming winds according to the mean wind speeds and the variances of wind speeds,and a group of turbines with similar wind are aggregated together.Simulations in a practical power system have been used to verify the effectiveness of the aggregation.
