摘要

以双馈型风电机组为研究对象,待优化的变量设定为风电场的无功功率以及并联电容器的投运组数,综合电压稳定性、电压偏差以及系统的有功网损3个指标,建立无功优化的模型;以改进的人工蜂群(modified artificial bee colony,MABC)算法为基础,研究无功优化在含双馈型风电场的配电网中的应用;选择IEEE 33节点系统,对算例进行测试,结果验证了MABC算法的可行性和有效性.%Doubly fed wind turbine was set as the research object,and the reactive power of the wind farm and the number of parallel capacitors were set as the variables and optimized.The best voltage stability,the least voltage deviation and the lowest active power loss were set as the optimized goal,then the optimized model of reactive power was established.Based on the modified artificial bee colony (MABC) algorithm,the application of reactive power optimization based on this modified algorithm in the distribution network that contained doubly-fed wind power was studied.IEEE 33 nodes system was chosen to verify the MABC algorithm.The results show that the reactive power optimization algorithm is feasible and effective.
