摘　　要：根据UPFC的稳态潮流模型,提出了基于原对偶内点法与自动微分(AD)技术相结合的含UPFC最优潮流算法。采用自动微分技术实现了雅可比矩阵和海森矩阵的自动生成,减少了微分表达式的推导,从而提高了开发效率。算例仿真结果表明,该算法对含UPFC的OPF模型具有良好的适用性和收敛性。ABSTRACT：The introduction of unified power flow controller （UPFC）has complicated the solving procedure of the optimal power flow（OPF）. This paper proposes an OPF algorithm incor-porating UPFC（solved by primal-dual interior point method）on the basis of combination of the steady state model of UPFC and the automatic differentiation（AD）technique. The AD technique is employed to establish the Jacobi and Hessian matrix automatically. Thus,the efficiency is improved by reducing the deduction of differential expressions. The proposed algorithm is verified on test cases to demonstrate its applicability and con-vergence.
