Abstract :
The paper presents a study of the convergence characteristics and an assessment of the performance of the algorithm used to solve power system state estimation problems. The algorithm is studied to determine and compare the convergence patterns using several measurement sets consisting of line flows, bus injections, voltage magnitudes and line currents. The algorithm was tested on different IEEE test systems. Results related to the test with IEEE 14 bus bar system are presented
