风电场群无功电压优化控制
|
摘要
提出了一种风电场群无功电压协调优化控制策略,以风电场群枢纽变电站母线电压及区域网损为控制目标,计及场群运行约束条件,特别考虑了风电场由于风功率波动导致的动态无功边界。经仿真验证,所提出的控制策略相对以并网点电压为控制模式优化了场群的电压分布,且能有效降低场群损耗。
Most wind farm voltage and reactive power control aims at the PCC voltage of the wind farm and it will not lead to an optimal reactive voltage distribution of the wind farm cluster. Based on this problem,this paper proposed a wind farm cluster voltage and reactive power coordination optimization control strategy. The control objectives of the strategy is the voltage of pilot bus in the cluster and the active power loss of the cluster. Also,it considers the constraint condition of the cluster and especially the dynamic boundary of wind farm reactive power caused by wind power fluctuation. Finally,the simulation validates that the proposed control strategy can optimize the reactive voltage distribution of the cluster and reduce the power loss.
