摘　　要：风场出力优化已成为规划设计风电场时迫切需要解决的问题。本文提出了计及暂态稳定约束的风场出力优化问题的数学模型,并明确了数学模型中目标函数及各约束条件的物理意义。分析了风场出力暂态稳定裕度灵敏度的计算方法,并基于风场出力暂态稳定裕度灵敏度这一指标提出了风场出力配置的优化算法,最后利用PSASP仿真论证了本文算法的有效性。Power output optimization of wind farm becomes an urgent problem to be solved during wind farm is planned and designed.In this paper,the mathematical model for power output optimization of wind farm under transient stability constraints is put forward,and the objective function and constraint criteria are defined.Based on the transient stability margin sensitivity of wind power output,influence of different wind farm on power system transient stability is analyzed,and the power output optimization algorithm of wind farms is put forward.In the end,the simulation based on PSASP verifies the effectiveness of the algorithm proposed in this paper.
