Abstract

An approach to solve the perturbated Optimal Power Flow (OPF) problem is proposed in this study. The methodology consists in obtaining the optimal solution for the initial problem via a program of OPF, and using sensitivity to estimate new solutions after the occurrence of some perturbations in the problem. These perturbations consist in load variations in some buses of the system. The sensitivity technique is based on both the information of second order and otimality conditions. The computation of the solutions after the occurrence of perturbations in the system does not depend of initial and correction parameters such as penalty and barrier used in the conventional OPF programs. The numerical results demonstrate the potential of this methodology for the solution of the perturbated OPF problem. (AU)
