Abstract :
A new approach to solving the optimal power flow problem is described, making use of some findings especially in the area of primal-dual methods for complex programming. In this approach, equality constraints are handled by Newton´s method inequality constraints for voltage and transformer taps by the logarithmic barrier method and the other inequality constraints by the augmented Lagrangian method. Numerical test results are presented, showing the effective performance of this algorithm
