包含统一潮流控制器的概率潮流研究

Probabilistic load flow computation concerning UPFC

提出了一种包含统一潮流控制器(UPFC)的概率潮流算法。UPFC采用等效注入功率模型,概率潮流采用非序贯蒙特卡罗仿真算法。讨论了UPFC的初值选取对潮流收敛性的影响,分析了发电机和线路随机故障时UPFC对线路潮流和节点电压的控制作用,并以EPRI和IEEE-RTS系统验证了蒙特卡罗仿真算法的正确性。

A probabilistic load flow algorithm concerning the Unified Power Flow Controller (UPFC) is presented. The UPFC adopts the power injection model,while in the probabilistic load flow computation,the nonsequential MonteCarlo simulation algorithm is adopted. The effects of the initial value selection of the UPFC on the convergence of power flow computation are discussed,and the control action of UPFC on the line flow and the node voltage is analyzed when the faults of the generator and the line occur randomly. The EPRI and IEEERTS systems prove the correctness of this method.
