摘　　要：风电场运行时有两个显著特点:有功出力具有随机性和需要吸收大量无功功率。大规模风电并网运行会对电力系统产生不利影响,需要对风电场接入系统进行无功优化规划。针对风电场有功出力随机性的特点,利用基于概率的场景方法研究风电场接入系统的无功优化问题,采用遗传算法求取最优解。利用风电场接入IEEE14节点系统进行仿真计算,得到的结果显示上述模型的正确性和有效性。The operation of the wind power plant has two major characteristics : the randomness of theactive power output and its demand for absorption of massive reactive power. Large scale wind power grid- connected operation would have adverse effects on the power system. Thus,it is necessary plan for reactive power of the access system of the wind power plant. In view of the randomness of thewind power plant,the probability analysis - based scenario method s used to study power of the access system of the wind power plant and the genetic algorithm s solution. Simulation calculation s carried out for the IEEE14 node system of the result shows that the above model is correct and valid.
