Oxford: Elsevier B.V., v. 27, n. 7, p. 528-532, 2005.0142-0615http://hdl.handle.net/11449/36575This paper presents a new approach to solve the Optimal Power Flow problem. This approach considers the application of logarithmic barrier method to voltage magnitude and tap-changing transformer variables and the other constraints are treated by augmented Lagrangian method. Numerical test results are presented, showing the effective performance of this algorithm. (C) 2005 Elsevier Ltd.
