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. © 2001 IEEE.126-130engInterior-point methodsNonlinear programmingOptimal power flowOptimization methodsAugmented Lagrangian methodsEffective performanceEquality constraintsInequality constraintInterior-point methodLogarithmic barriersNewton's methodsNumerical testsOptimal power flow problemOptimal power flowsOptimization methodPrimal-dual methodsConstraint theoryElectric load flowLagrange multipliersNewton-Raphson methodAcoustic generatorsTrabalho apresentado em evento10.1109/PTC.2001.964895Acesso aberto2-s2.0-5154909919284796874045269580000-0002-5642-8925
