A Multi-Function Power System Loa dFlow Calculating Algorithm

A new algorithm gor power system load flow calculation is proposed. Load flow calculation by the new method makes use of a linear mathematical model without the necessity of any additional assumption in model handling. The main advantages of the method proposed are faster calculation and better convergence as compared with the Newton-Raphson method. This method gives rapid convergence for those systems where when the P-Q decomposition method is used it is not easy to get converged. It guarantees convergence even when ill-conditioned power systems are involved. For most power systems, the calculating speed with this method is comparable with that of the P-Q decomposition method. It can be used to deal with either symmetrical or asymmetrical faults.
