Control Method of the Wind Farm in Frequency Control Considering Dynamic Performance

Abstract

With the increase installed capacity of wind energy, conventional generation starts to be replaced by wind farms, which will results in erosion of system frequency. It is thus imperative to develop advanced wind turbine control method to maintain the frequency. Considering the calculating complication of full-order models, this paper proposed a reduced wind turbine model with optimal dynamic performance. In order to improve the performance of the whole wind farm in frequency control, this work proposes a coordinate method at constant power control model for the goal of optimal dynamic response of the wind farm, considering the differences in operation state and wind speed of each wind turbine. Finally, the correctness and effectiveness of the proposed method are validated by the simulation.
