Abstract

The reactive optimal power flow is a non convex, non linear, constrained optimization problem with discrete and continuous variablesand large scale. This problem aims to seek the best point of operation of an electric system according to a determined criterion. This project proposes a new approach that uses the interior point method and penalty method for the solution of optimal power flow problem with discrete control variables. For the treatment of the discrete variables will be used a strategy that transforms the discrete problem in a continuous problem using a penalty function which forces the variables to assumediscrete values. It is expected to contribute to the non linear optimization area with an efficient approaching and in determining of optimal power flow reactive solution. (AU)
