Power Perturbation Method for Power Flow Analysis

This paper proposes an improved load flow method based on perturbation theory which is simple, efficient and reliable. The performance of the proposed method has been tested on well-conditioned IEEE 5-bus, 14-bus, 30 bus and also tested on 11-bus ill conditioned test systems. The proposed method shows its efficacy and robustness with minimum number of iterations along with high accuracy on conventional load flow methods like G-S (Gauss-Siedal) method.
