摘要
给出了电力系统最优潮流(OPF)的数学模型以及求解该模型的非线性原一对偶内点法,在阐述OPF数学模型的基础上,对基于非线性原-对偶内点法的OPF算法进行了详细的数学描述。并就改善内点法的2种高阶校正策略进行了论述,通过对3个不同规模电力系统的数值计算,验证了2种策略对于不同规模系统均优于原-对偶内点法,同时指出2种策略对不同规模系统有着不同的适应性。
Since the successful interior point algorithms for power system optimization problems in 1990s,the algorithms have been widely used in the optimal power flow area. Besides describing the OPF model,this paper focuses on the nonlinear primal-dual interior point algorithm and higher-order correction strategies. Numerical results of three test system ranging in size from 118 to 662 buses are presented. The computational results have shown that the algorithm and strategies are very effective.
