Owing to the large physical area of a wind farm, some uncertainty and inefficiency issues exist in the related power delivery process. To provide required ancillary services regarding reactive power for the utility grid, further optimization processes are needed to maintain the reliability and efficiency of the entire system. In this paper, we introduce a reactive power assignment strategy that is based on the linearized system components of a wind farm, which comprises a power conversion system. Additionally, we perform realistic assignment processes to verify the effectiveness of this strategy with electromagnetic transients using dc software tool. Reducing the total apparent power flow by utilizing the radial structure of the wind farm is explored by assigning reactive power to nearby wind turbines. The verification process focuses on comparing the loss in output profile of a normal assignment and the proposed method in a designated wind farm.
