Calculation of transfer capability of power systems using an efficient predictor-corrector primal dual interior point algorithm

In this paper, we employ an optimization approach with continuation power f low equality constraints for investigating stationary steady state behavior of power systems. We consider varying load and generation patterns to dete rmine real power transfer capability for power systems subject to system an d network constraints. A new algorithm using the primal-dual interior point method with the predictor-corrector for determination of maximum loadabili ty in a power system is presented in this paper. The method is new because it deals with the application of an advanced interior point method to maxim um loadability problem through successive linear programming (SLP). The non linear maximum loadability problem is linearized and solved by a predictor- corrector interior point method. This method is applied to the IEEE14 bus s ystem.
