                    以统一潮流控制器(UPFC)为代表的灵活交流输电系统(FACTS)技术可以实现传输功率的合理分布、优化系统资源,提高系统的稳定性和可靠性。基于内点优化方法,提出了计及UPFC的无功优化模型,以系统网损最小为目标函数,采用UPFC电压源模型,将其作用等效为一系列电压和功率的约束,直接放到内点法的约束中,在不同的负荷运行方式下进行了优化分析。用IEEE-30节点系统进行了测试,引入UPFC后系数矩阵的维数会有所增加,但不会影响其收敛性。结果表明该方法是可行的、有效的,取得了很好的效果。
                
                The technique of Flexible AC transmission system(FACTS), especially unified power flow controller(UPFC), could be used to realize the reasonable distribution of power flow and optimization of system resources, improve the stability and reliability of the system. This paper proposes a model for reactive power optimization with UPFC. It minimizes the loss of the system, adopts the UPFC voltage source model and transforms their effect into a series of restricts of voltage and power, which are analyzed in different load operational modes based Interior Point Method. The tests of IEEE-30 bus indicate that the proposed method is effective and feasible.
