Power flow analysis of power system using Power Perturbation method

Computation of load flows is the most fundamental power system operation and planning problem. In large power system, nodal voltage method of network solution using admittance matrix is preferred. In order to study its parallel algorithms, which improve operation efficiency, enhancement of real-time control and timely decision support, an improved load flow method based on perturbation theory has been proposed. The new proposed method is tested with the IEEE 5-bus, IEEE 14-bus, IEEE 30-bus and IEEE 118-bus systems. The numerical result shows its efficiency and performance over conventional Gauss-Seidal method.
