摘　　要：文章基于改进飞蛾火焰优化算法,提出了一种风电汇集区域统一潮流控制器优化配置方案。该方案以潮流平衡及各系统参数为约束,以降低有功网损、改善电压水平、合理控制线路负载率为目标,开展统一潮流控制器补偿地点与容量的联合寻优。采用改进飞蛾火焰优化算法,引入Kent混沌搜索策略增强寻优能力,并与原飞蛾火焰算法进行比较。通过IEEE-14标准节点测试模型开展实验,表明所得优化配置方案能够有效提升电压与负载率水平,降低系统网损。With the increasing of wind power grid-connected capacity,the problem of heavy line and voltage drop in the wind power gathering area are increased significantly.Reasonable configuration of the unified power flow controller can effectively solve those problems.Therefore,an optimal configuration scheme of UPFC system in wind power gathering area based on improved moth flame optimization algorithm is proposed.The tidal current equilibrium equation is used as the equality constraint.The load flow balance and system parameters are taken as constrains.Aiming at reducing active power loss and improving voltage level and reasonable control line load rate,carry out the joint optimization of UPFC compensation locating and sizing.The improved AMFO algorithm and introducing Kent chaotic search strategy is used to enhance the optimization ability and compare with the original MFO.The experiment is carried out on the IEEE-14 node test system.The experiment results indicate that the optimized configuration scheme obtained by the new method can effectively improve the voltage level and load rate,and reduce the network loss.
